Subject: [PATCH 0023/2315] Tidy up classpath pollution caused by resource
 creation in the tests

Previously, spring-webmvc and spring-webflux both contained tests
that would create gzipped files, write them to the filesystem
alongside the project's compiled test classes, and configure them to
be deleted on JVM exit. The output location placed the files on the
classpath, polluting it for every subsequent test that used the same
ClassLoader. The test-sources plugin combined with Gradle's use of
worker JVMs, broadens the scope of this pollution to other, downstream
projects in the same build. For example, the tests for
spring-websocket will have a different classpath depending on whether
or not the tests for spring-webmvc have already been run on the same
worker as part of the current build.

This commit updates the spring-webmvc and spring-webflux modules to
introduce a new JUnit Jupiter extension, GzipSupport. This extension
allows gzipped files to be created via an injectable GzippedFiles
class and automatically deletes each created file in an after-each
callback. This ensures that a gzipped file only exists on the
classpath for the duration of the test that needs it, avoiding the
pollution of the classpath of any subsequent tests.

Closes gh-23970

Subject: [PATCH 0048/2315] Fix schemaZip Gradle task on MS Windows

Prior to this commit, the schemaZip Gradle task failed to find Spring
schema files on MS Windows due to path separators hard coded to forward
slashes that are not compatible with the Windows operating system.

Consequently, a full build failed on Windows since the distZip task was
not able to locate the zipped schema archive that the schemaZip task
failed to create.

This commit fixes this by updating the schemaZip task to search for
schema files using backslashes as well as forward slashes.

Closes gh-23933

Subject: [PATCH 0059/2315] Inverse condition to fix ISO-formatted Instant
 parsing

Prior to this commit, InstantFormatter was able to properly serialize
an Instant that is far in the future (or in the past), but it could not
properly deserialize it, because in such scenarios an ISO-formatted
Instant starts with a +/- sign.

This commit fixes this issue, while maintaining the previous contract,
and also introduces tests for InstantFormatter.

Closes gh-23895

Subject: [PATCH 0066/2315] Refine MethodParameter#isOptional Kotlin
 implementation

This commit adds support for Continuation parameter that is now
considered as an optional parameter since it is never provided by
the user.

It also simplifies and optimizes the implementation.

Closes gh-23991

Subject: [PATCH 0077/2315] Use method signature to refine RSocket
 @MessageMapping

Before this change an @MessageMapping could be matched to any RSocket
interaction type, which is arguably too flexible, makes it difficult to
reason what would happen in case of a significant mismatch of
cardinality, e.g. request for Fire-And-Forget (1-to-0) mapped to a
method that returns Flux, and could result in payloads being ignored,
or not seen unintentionally.

This commit checks @ConnectMapping method on startup and rejects them
if they return any values (sync or async). It also refines each
@MessageMapping to match only the RSocket interaction type it fits
based on the input and output cardinality of the handler method.
Subsequently if a request is not matched, we'll do a second search to
identify partial matches (by route only) and raise a helpful error that
explains which interaction type is actually supported.

The reference docs has been updated to explain the options.

Closes gh-23999

Subject: [PATCH 0079/2315] Support scoped @ControllerAdvice beans again

Spring Framework 5.2 introduced support for implementing the Ordered
interface in a @ControllerAdvice bean. This support requires that
@ControllerAdvice beans be eagerly resolved from the BeanFactory in
order to invoke the getOrder() method defined in the Ordered interface.
Unfortunately doing so resulted in a regression in that an attempt to
eagerly resolve a scoped @ControllerAdvice bean throws a
BeanCreationException due to the lack of an active scope (e.g., request
or session scope).

This commit fixes this regression by avoiding eager resolution of scoped
@ControllerAdvice beans. As a direct consequence, the Ordered interface
is not supported for scoped @ControllerAdvice beans.

Closes gh-23985

Subject: [PATCH 0082/2315] Ignore scoped proxy targets for @ControllerAdvice
 beans

Prior to this commit, methods in a @ControllerAdvice bean were
registered and invoked twice if the advice was a scoped bean (e.g.,
request or session scoped). In other words, both the proxy bean and the
target bean were wrapped in ControllerAdviceBean instances.

This commit fixes this bug by modifying the findAnnotatedBeans() method
in ControllerAdviceBean so that it filters out targets of scoped
proxies.

Closes gh-24017

Subject: [PATCH 0099/2315] Improve HttpHandlerConnection completion

Before this commit the connector waited for a completed response (via
ServerHttpResponse#setComplete or ServerHttpResponse#writeWith) or an
error signal in handling, but it didn't deal explicitly with the case
where both can occur.

This commit explicitly waits for the completion of handling (success
or error) before passing the response downstream. If an error occurs
after response completion, it is wrapped in a dedicated exception that
also provides access to the completed response.

Subject: [PATCH 0100/2315] Refine Coroutines annotated controller support

This commit refines Coroutines annotated controller support
by considering Kotlin Unit as Java void and using the right
ReactiveAdapter to support all use cases, including suspending
functions that return Flow (usual when using APIs like WebClient).

It also fixes RSocket fire and forget handling and adds related tests
for that use case.

Closes gh-24057
Closes gh-23866

Subject: [PATCH 0112/2315] Expose method to determine form content type

This commit exposes the method that returns the media type used to write
forms. By default, it includes the charset in the content type, which
can cause issues with certain consumers. This commit changes the method
from a private to a protected method, so that users can override the
default behavior.

 1. Always check out the `master` branch and submit pull requests against it
 (for target version see [settings.gradle](settings.gradle)).
 Backports to prior versions will be considered on a case-by-case basis and reflected as
 the fix version in the issue tracker.
 
-1. Use short branch names, preferably based on the GitHub issue (e.g. `22276`), or
-otherwise using succinct, lower-case, dash (-) delimited names, such as `fix-warnings`.
-
 1. Choose the granularity of your commits consciously and squash commits that represent

This commit introduces failing assertions that are currently disabled
via a boolean reproduceGh24077 flag.

Setting that flag to true demonstrates the regression for
StandardAnnotationMetadata and inconsistencies for SimpleAnnotationMetadata.

Subject: [PATCH 0131/2315] Support @Inherited again in reflection-based
 AnnotationMetadata

Spring Framework 5.2 introduced a regression in reflection-based
AnnotationMetadata. Specifically, as of 5.2, StandardAnnotationMetadata
no longer found @Inherited annotations from superclasses.

This commit fixes this regression by switching to the INHERITED_ANNOTATIONS
SearchStrategy when creating the MergedAnnotations used within
StandardAnnotationMetadata,

Note, however, that the discrepancy between StandardAnnotationMetadata
and SimpleAnnotationMetadata (i.e., reflection-based vs. ASM-based)
regarding @Inherited support still remains as it was prior to Spring
Framework 5.2.

Closes gh-24077

Subject: [PATCH 0138/2315] Enable reading from the remote build cache for all

Previously, the remote build cache was only enabled if the
GRADLE_ENTERPRISE_URL environment variable was configured. This meant
that contributors would not benefit from the build time improvements
of the caching without some additional setup.

This commit updates the buildCache configuration so that reading from
the remote build cache at https://ge.spring.io is enabled for all.
Pushing to the cache continues to be disabled unless the required
credentials are provided. Build scan configuration has also been
updated in line with this change. While the server URL is now
hardcoded, publishing is still opt-in via an environment variable.
The exact mechanism by which someone can opt in will change in the
future once some server-side changes have been made. At this point,
only a change to publishAlwaysIf should be necessary.

Closes gh-24105

Subject: [PATCH 0142/2315] Allow ExchangeStrategies customizations in
 WebClient

Prior to this commit, developers could configure their WebClient to use
their custom `ExchangeStrategies`, by providing it in the
`WebClient.Builder` chain.
Once created, an `ExchangeStrategies` instance is not mutable, which
makes it hard for further customizations by other components. In the
case of the reported issue, other components would override the default
configuration for the codecs maxInMemorySize.

This commit makes the `ExchangeStrategies` mutable and uses that fact to
further customize them with a new `WebClient.Builder#exchangeStrategies`
`Consumer` variant. This commit is also deprecating those mutating
variants in favor of a new `WebClient.Builder#exchangeStrategies` that
takes a `ExchangeStrategies#Builder` directly and avoids mutation issues
altogether.

Closes gh-23961

+=== MaxInMemorySize
+
+Spring WebFlux configures by default a maximum size for buffering data in-memory when decoding
+HTTP responses with the `WebClient`. This avoids application memory issues if the received
+response is much larger than expected.
+
+The default configured value of 256KB might not be enough for your use case, and your application
+might hit that limit with the following:
+
+----
+org.springframework.core.io.buffer.DataBufferLimitException: Exceeded limit on max bytes to buffer

+
+You can configure this limit on all default codecs with the following code sample:

Subject: [PATCH 0150/2315] Allow ExchangeStrategies customizations in
 WebClient

Prior to this commit, developers could configure their WebClient to use
their custom `ExchangeStrategies`, by providing it in the
`WebClient.Builder` chain.
Once created, an `ExchangeStrategies` instance is not mutable, which
makes it hard for further customizations by other components. In the
case of the reported issue, other components would override the default
configuration for the codecs maxInMemorySize.

This commit makes the `ExchangeStrategies` mutable and uses that fact to
further customize them with a new `WebClient.Builder#exchangeStrategies`
`Consumer` variant. This commit is also deprecating those mutating
variants in favor of a new `WebClient.Builder#exchangeStrategies` that
takes a `ExchangeStrategies#Builder` directly and avoids mutation issues
altogether.

Closes gh-23961

+=== MaxInMemorySize
+
+Spring WebFlux configures by default a maximum size for buffering data in-memory when decoding
+HTTP responses with the `WebClient`. This avoids application memory issues if the received
+response is much larger than expected.
+
+The default configured value of 256KB might not be enough for your use case, and your application
+might hit that limit with the following:
+
+----
+org.springframework.core.io.buffer.DataBufferLimitException: Exceeded limit on max bytes to buffer
+----
+
+You can configure this limit on all default codecs with the following code sample:
 
+[source,java,indent=0,subs="verbatim,quotes",role="primary"]
+.Java
+----
+	WebClient webClient = WebClient.builder()
+			.exchangeStrategies(configurer ->

Subject: [PATCH 0157/2315] Provide default codecs config callback to custom
 codecs

As a follow-up of gh-23961, this change provides a way for custom codecs
to align with the default codecs' behavior on common features like
buffer size limits and logging request details.

Closes gh-24118

Subject: [PATCH 0160/2315] Honor default values for implicit aliases in
 composed annotations

Spring Framework 5.2 introduced a regression for implicit aliases
declared via @AliasFor. Specifically, Spring's merged annotation
algorithms stopped honoring default values for implicit alias pairs if
the composed annotation was used without specifying the aliased
attributes.

This commit fixes this regression.

Closes gh-24110

 [CAUTION]
 ====
-When using `exchange()`, you have to make sure that the body is always consumed or released,
-even when an exception occurs (see <<core.adoc#databuffers-using,Using DataBuffer>>).
-Typically, you do this by invoking either `bodyTo*` or `toEntity*` on `ClientResponse`
-to convert the body into an object of the desired type, but
-you can also invoke `releaseBody()` to discard the body contents without consuming it or
-`toBodilessEntity()` to get just the status and headers (while discarding the body).
-
-Finally, there is `bodyToMono(Void.class)`, which should only be used if no response content is
-expected.
-If the response does have content, the connection is closed and is not placed back in the pool,
-because it is not left in a reusable state.
+Unlike `retrieve()`, when using `exchange(), it is the responsibility of the application

Subject: [PATCH 0171/2315] Support variable resolution of wildcard types

Update `ResolvableType` so that variable referenced can be resolved
against wildcard types. Prior to this commit, given a type:

	Map<String, ? extends List<? extends CharSequence>>

Calling `type.getGeneric(1).asCollection().resolveGeneric()` would
return `null`. This was because the `List` variable `E` referenced a
wildcard type which `resolveVariable` did not support.

Closes gh-24145

Subject: [PATCH 0176/2315] Do not cache prototype @ControllerAdvice beans

Spring Framework 5.2 introduced support for caching @ControllerAdvice
beans; however, this caching was also applied incorrectly to
non-singleton beans.

This commit addresses this regression by only caching singleton
@ControllerAdvice beans.

Closes gh-24157

Subject: [PATCH 0189/2315] Improve exception for mixed explicit/implicit
 aliases with @AliasFor

Given the following improperly configured composed @RequestMapping
annotation:

@Retention(RetentionPolicy.RUNTIME)
@RequestMapping
@interface PostApi {

	@AliasFor("value")
	String[] path() default {};

	@AliasFor(annotation = RequestMapping.class, attribute = "path")
	String[] value() default {};
}

Prior to this commit, an attempt to process the above annotation
resulted in an exception similar to the following, which is not
especially helpful to discern the problem.

> Attribute 'value' in annotation [PostApi] must be declared as an
> @AliasFor 'path', not 'path'.

This commit improves the exception message for such scenarios,
resulting in an exception message similar to the following.

> Attribute 'value' in annotation [PostApi] must be declared as an
> @AliasFor attribute 'path' in annotation [PostApi], not attribute
> 'path' in annotation [RequestMapping].

Closes gh-24168

Subject: [PATCH 0197/2315] Make TYPE_HIERARCHY_AND_ENCLOSING_CLASSES
 annotation search strategy defensive

Prior to this commit, when searching for annotations using the
TYPE_HIERARCHY_AND_ENCLOSING_CLASSES strategy an exception could be
thrown while attempting to load the enclosing class (e.g., a
NoClassDefFoundError), thereby halting the entire annotation scanning
process.

This commit makes this search strategy defensive by logging exceptions
encountered while processing the enclosing class hierarchy instead of
allowing the exception to halt the entire annotation scanning process.

The exception handling is performed by
AnnotationUtils.handleIntrospectionFailure() which only allows an
AnnotationConfigurationException to propagate.

Subject: [PATCH 0200/2315] Handle exceptions in annotation searches again

Prior to Spring Framework 5.2, most annotation search algorithms made
use of AnnotationUtils.handleIntrospectionFailure() to handle exceptions
thrown while attempting to introspect annotation metadata. With the
introduction of the new MergedAnnotation API in Spring Framework 5.2,
this exception handling was accidentally removed.

This commit introduces the use of handleIntrospectionFailure() within
the new MergedAnnotation internals in order to (hopefully) align with
the previous behavior.

Closes gh-24188

Subject: [PATCH 0206/2315] Add register methods to
 CodecConfigurer.CustomCodecs

The new register methods replace the now deprecated
encoder, decoder, reader, and writer methods, and also offer a choice
to opt into default properties such maxInMemorySize, if configured.

See gh-24124

Subject: [PATCH 0207/2315] Expose ClientCodecConfigurer in WebClient.Builder

Using Consumer<ClientCodecConfigurer> instead of
Consumer<ExchangeStrategies> eliminates one level of nesting that is
also unnecessary since codecs are the only strategy at present.

Closes gh-24124

Subject: [PATCH 0232/2315] Improve UriBuilder Javadoc on query params

Add a note on encoding for query parameters specifically mentioning the
"+" sign and a link to the reference docs.

Also remove duplicate Javadoc in UriComponentsBuilder which is already
inherited from UriBuilder.

Subject: [PATCH 0240/2315] Remove quality parameter from selected media type

Prior to this commit, WebFlux application would keep the quality
parameter from the "Accept" request header when selecting a media type
for the response. It would then echo it back to the client.

While strictly not wrong, this is unnecessary and can confuse HTTP
clients. This commit aligns WebFlux's behavior with Spring MVC.

Fixes gh-24239

Subject: [PATCH 0265/2315] Remove Content-* response headers for error
 handling

Prior to this commit, when WebFlux handlers added `"Content-*"` response
headers and an error happened while handling the request, all those
headers would not be cleared from the response before error handling.

This commit clears those headers from the response in two places:
* when invoking the handler and adapting the response
* when writing the response body

Not removing those headers might break HTTP clients since they're given
wrong information about how to interpret the HTTP response body: the
error response body might be very different from the original one.

Fixes gh-24238

Subject: [PATCH 0277/2315] Introduce BeanNameGenerator based on fully
 qualified class name

Prior to this commit, Spring offered two top-level implementations of
the BeanNameGenerator strategy: DefaultBeanNameGenerator and
AnnotationBeanNameGenerator. The latter is used as the default bean
name generator for beans picked up via component scanning. In a typical
application, this strategy works well; however, if multiple component
scanned beans have the same simple class name (i.e., identical names
ignoring the package), a BeanDefinitionStoreException is thrown.

To address such naming conflicts, users of Spring have had to implement
a custom BeanNameGenerator based on the fully qualified class name of
such components.

Similar conflicts can arise with components registered via
configuration class imports (i.e., via @Import), and
ConfigurationClassPostProcessor addresses this via an anonymous inner
class that extends AnnotationBeanNameGenerator but falls back to using
the fully qualified class name if an explicit bean name is not provided
via an annotation.

This commit extracts the implementation of
ConfigurationClassPostProcessor's internal BeanNameGenerator into a new
top-level FullyQualifiedAnnotationBeanNameGenerator class that can be
used to disambiguate between same-named components residing in
different packages that are picked up via component scanning. This bean
name generator can be configured via @ComponentScan's nameGenerator
attribute.

Closes gh-24114

Subject: [PATCH 0288/2315] Always configure PDF backend as task will only run
 on cache miss

Previously, the Asciidoctor task was not cacheable and generating the
PDF documentation was very slow. To improve build times, the PDF
documentation was not generated for snapshot builds.

The upgrade to 2.4.0 of the Asciidoctor Gradle pluging means that the
Asciidoctor task is now cacheable. As such, its tasks will only run
when the documentation has changed. This should allow PDF
documentation to be published for every build without slowing things
down too much and the cost of generating the documentation will only
be incurred when there is a change to the documentation.

See gh-24216

Subject: [PATCH 0289/2315] Return 500 if producible attribute present

When a request is mapped through a producible condition on an
@RequestMapping, then a failure to find a converter/decoder should be
a 500 because the return type + media type pair were declared by the
controller and that should be possible to render.

Closes gh-23287

Subject: [PATCH 0300/2315] Update CORS support

This commit updates CORS support in order to check Origin header
in CorsUtils#isPreFlightRequest which does not change how Spring
MVC or WebFlux process CORS request but is more correct in term
of behavior since it is a public API potentially used in another
contexts.

It also removes an unnecessary check in
AbstractHandlerMethodMapping#hasCorsConfigurationSource and processes
every preflight request with PreFlightHandler.

Closes gh-24327

Subject: [PATCH 0307/2315] Improve limit handling in StringDecoder

The case of one data buffer containing multiple lines can could cause
a buffer leak due to a suspected issue in concatMapIterable. This
commit adds workarounds for that until the underlying issue is
addressed.

Subject: [PATCH 0325/2315] Publish a build scan only if authenticated

Previously, anyone could publish a scan and publishing was performed
if the GRADLE_ENTERPRISE_URL environment variable was set.

ge.spring.io has now been locked down to prohibit anonymous build scan
publishing. This commit aligns with this change by only attempting to
publish a build scan when authenticated with the server.

Authentication is achieved via an access token that is made available
via an environment variable on CI and locally via a file in ~/.gradle.

One can obtain an access key by running the following command:

./gradlew provisionGradleEnterpriseAccessKey

Subject: [PATCH 0335/2315] Avoid setting special Content-* response headers
 for Tomcat

As of gh-21783, Spring WebFlux uses a `TomcatHeadersAdapter`
implementation to directly address the native headers used by the
server.

In the case of Tomcat, "Content-Length" and "Content-Type" headers are
processed separately and should not be added to the native headers map.

This commit improves the `HandlerAdapter` implementation for Tomcat and
removes those headers, if previously set in the map. The adapter
already has a section that handles the Tomcat-specific calls for such
headers.

Fixes gh-24361

Subject: [PATCH 0342/2315] Use Jackson SequenceWriter for streaming

Before this commit, the AbstractJackson2Encoder instantiated a
ObjectWriter per value. This is not an issue for single values or
non-streaming scenarios (which effectively are the same, because in the
latter values are collected into a list until offered to Jackson).
However, this does create a problem for SMILE, because it allows for
shared references that do not match up when writing each value with a
new ObjectWriter, resulting in errors parsing the result.

This commit uses Jackson's SequenceWriter for streaming scenarios,
allowing Jackson to reuse the same context for writing multiple values,
fixing the issue described above.

Closes gh-24198

Subject: [PATCH 0345/2315] Expose media type mappings in
 ContentNegotiationManager

ContentNegotiationManagerFactoryBean now ensures that
ContentNegotiationManager contains the MediaType mappings even if the
path extension and the parameter strategies are off.

There are also minor fixes to ensure the media type mappings in
ContentNegotiationManagerFactoryBean aren't polluted when mapping keys
are not lowercase, and likewise MappingMediaTypeFileExtensionResolver
filters out duplicates in the list of all file extensions.

See gh-24179

Subject: [PATCH 0346/2315] Deprecate path extension strategies

This commit deprecates PathExtensionContentNegotiationStrategy and
ServletPathExtensionContentNegotiationStrategy and also updates code
that depends on them internally to remove that dependence.

Reactor Netty's TcpResources itself uses fixed 500 by default, we
update to have the same value which would apply when global resources
are not used.

Subject: [PATCH 0366/2315] Add Informix to the list of supported database
 products for procedure calls

Hi guys,

We're facing an issue in our application when we try to call a procedure in Informix database,
our app uses standard JDBC (spring-jdbc and com.ibm.informix.jdbc.4.50.3) without Hibernate
to connect to the database

Issue:
When we trying to execute any procedure call in our Informix database there is no data returned.

Diagnostic:
It points to the Java class called CallMetaDataProviderFactory in spring-jdbc project.

Taking a look of this class there is no explicit support for Informix procedure calls, so I added "Informix Dynamic Server" to the
list of supported databases and now I can execute procedures call without issues.

Basically I added the line "Informix Dynamic Server" to the list called "supportedDatabaseProductsForProcedures"
of CallMetaDataProviderFactory class in my local environment and it worked as expected.


I really appreciate any feedback/suggestion for this approach due we would like to continue using the framework
normally in our development without losing updates using a workaround in our end.

Many thanks in advance.

Subject: [PATCH 0378/2315] Support optional command line arguments with empty
 values

Spring Framework provides two implementations of the
CommandLinePropertySource API: SimpleCommandLinePropertySource and
JOptCommandLinePropertySource.

Prior to this commit, JOptCommandLinePropertySource supported empty
values for optional arguments; whereas, SimpleCommandLinePropertySource
did not.

This commit modifies the implementation of SimpleCommandLinePropertySource
to allow empty values for optional arguments.

Closes gh-24464

Subject: [PATCH 0404/2315] Support alternate JDK versions in Gradle build

This commit adds support for the following two JVM system properties
that control the Gradle build for alternative JDKs (i.e., a JDK other
than the one used to launch the Gradle process).

- customJavaHome: absolute path to the alternate JDK installation to
  use to compile Java code and execute tests. Setting this system
  property causes Groovy 3.0 RC3 to be used instead of 2.5.x. This
  system property is also used in spring-oxm.gradle to determine
  whether JiBX is supported.

- customJavaSourceVersion: Java version supplied to the `--release`
  command line flag to control the Java source and target compatibility
  version. Supported versions include 9 or higher. Do not set this
  system property if Java 8 should be used.

Examples:

./gradlew -DcustomJavaHome=/opt/java/jdk-14 test

./gradlew --no-build-cache -DcustomJavaHome=/opt/java/jdk-14 test

./gradlew -DcustomJavaHome=/opt/java/jdk-14 -DcustomJavaSourceVersion=14 test

Subject: [PATCH 0407/2315] Ignore warnings for missing classpath elements with
 custom JAVA_HOME

Prior to this commit, the "-Werror" was removed as a command-line
argument in order not to fail the build for missing classpath elements.

This commit reinstates "-Werror" and removes "-Xlink:path" in order to
explicitly ignore warnings for missing classpath elements when executing
the build with a custom JAVA_HOME.

Subject: [PATCH 0411/2315] Upgrade to Spring Asciidoctor Extensions
 0.4.0.RELEASE

0.4.0 provides built-in support for remembering a user's selections
using local storage. This replaces the custom switch language
JavaScript.

The selection is stored using a key derived from the
options that were available. Concretely, when the options are Java or
Kotlin, the local storage key is java-kotlin. Similarly, if the
choices were Java, Kotlin, and XML, the key would be java-kotlin-xml.

Given local storage's domain and protocol scoping, the nature of the
key that's used for storage will allow a user's selections to be
applied across all documentation hosted on https://docs.spring.io that
offer the same options.

Closes gh-24481

Subject: [PATCH 0412/2315] Force TokenBuffer to use BigDecimal if elementtype

This commit makes the Jackson2Tokenizer enable
TokenBuffer.forceUseOfBigDecimal if the element type given to the
Decoder is BigDecimal. Previous to this commit, values would be
converted to floats.

Subject: [PATCH 0421/2315] Eliminate windowUntil from StringDecoder

This is a follow-up on the earlier commit
28a95e89f35600199ee1254dee9e8ed53f958bcc eliminating windowUntil
entirely which generates a BubblingException wrapper. This also keeps
the chain a little simpler.

Subject: [PATCH 0423/2315] Support nested annotations in ASM-based processing
 again

Spring Framework 5.0 introduced a regression in ASM-based annotation
processing. Specifically, nested annotations were no longer supported,
and component scanning resulted in an exception if a candidate
component was annotated with an annotation that contained nested
annotations.

This commit fixes this regression by introducing special handling in
AnnotationTypeMapping that supports extracting values from objects of
type TypeMappedAnnotation when necessary.

Closes gh-24375

Subject: [PATCH 0426/2315] Simplify custom_java_home.gradle script

Setting `options.fork = true` causes the classpath in the forked
compiler process to include Class-Path entries from MANIFEST.MF files
in JARs in the classpath, which results in warnings about missing
classpath entries.

This commit removes the `options.fork = true` declaration and further
simplifies the script.

Subject: [PATCH 0427/2315] Support SpEL compilation of interface methods again

Spring Framework 5.1.8 introduced a regression for the compilation of
SpEL expressions referencing a method declared in an interface. An
attempt to compile such an expression resulted in a
SpelEvaluationException caused by an IncompatibleClassChangeError.

This commit fixes this regression by adding explicit support in
ReflectivePropertyAccessor.OptimalPropertyAccessor.generateCode() for
methods declared in interfaces.

Closes gh-24357

Subject: [PATCH 0437/2315] Mark response as complete before WebSocket upgrade

Prior to this commit, some WebSocket `RequestUpgradeStrategy` reactive
implementations would prevent the application from writing HTTP headers
and cookies to the response.

For Reactor Netty and Undertow, handling the upgrade and starting the
WebSocket communication marks the response status and headers as sent
and the application cannot update HTTP response headers after that.

This commit ensures that the `RequestUpgradeStrategy` implementations
mark the responses as "complete", so that headers are written before we
delegate to the server implementation.

Fixes gh-24475

Subject: [PATCH 0440/2315] Remove unnecessary dependency on spring-orm

Prior to this commit, spring-aspects would consider spring-orm as a
module providing aspects, which is not the case (anymore).
This commit removes that dependency as a result.

Fixes gh-24491

Subject: [PATCH 0442/2315] Consistently call setComplete before WS upgrade

Even thought Tomcat and Jetty, which commit the response more lazily,
were not impacted by this issue, it still makes sense for them to
complete the WebFlux response (and pre-commit actions) at the same time
as for other servers for consistent behavior.

See gh-24475

Subject: [PATCH 0445/2315] Remove producible request attribute before mapping

The attribute was previously removed only before exception resolution
in the DispatcherServlet in order to allow error rendering to make an
independent choice on content negotation.

However, Boot rendering happens later in an ERROR dispatch which could
also be a nested dispatch on some servers. So the attribute must also
generally be removed prior to mapping.

We also move the methods where this is done to the base
RequestMappingInfoHandlerMapping class which also deals with the
produces condition and where the producible attribute is added in the
first place.

Subject: [PATCH 0466/2315] Configure quiet period for shutting down Reactor
 resources

This commit adds two new properties to the `ReactorResourceFactory`.
This allows to configure the quiet and timeout periods when shutting
down Reactor resources. While we'll retain Reactor Netty's default for
production use, this option is useful for tests and developement
environments when developers want to avoid long waiting times when
shutting down resources.

Fixes gh-24538

-NOTE: Joda-Time provides separate distinct types to represent `date`, `time`, and `date-time`
-values. The `dateFormatter`, `timeFormatter`, and `dateTimeFormatter` properties of the
-`JodaTimeFormatterRegistrar` should be used to configure the different formats for each
-type. The `DateTimeFormatterFactoryBean` provides a convenient way to create formatters.
-
-NOTE: If you use Spring MVC, remember to explicitly configure the conversion service that
-is used. For Java-based `@Configuration`, this means extending the
-`WebMvcConfigurationSupport` class and overriding the `mvcConversionService()` method.
-For XML, you should use the `conversion-service` attribute of the
-`mvc:annotation-driven` element.
-See <<web.adoc#mvc-config-conversion, Conversion and Formatting>> for details.
-
+Note there are extra considerations when configuring date and time formats in web
+applications. Please see

Subject: [PATCH 0482/2315] Relax GraalVM check in
 DefaultParameterNameDiscoverer

Prior to this commit, DefaultParameterNameDiscoverer did not register
any discovers when compiling or running as a GraalVM native image.

This commit relaxes the GraalVM check so that it is only applied to the
registration of KotlinReflectionParameterNameDiscoverer.

Consequently, StandardReflectionParameterNameDiscoverer and
LocalVariableTableParameterNameDiscoverer are once again always
registered by DefaultParameterNameDiscoverer.

Closes gh-24600

 to enable autowiring for all parameters.

Subject: [PATCH 0498/2315] Remove unnecessary calls to disableContentCaching

These calls were added in error when trying to fix #22797 and #23775.
They are not needed in 304 scenarios. Those have no response content and
are skipped by ShallowETagHeaderFilter based on the status.

This leaves disableContentCaching invoked only in streaming scenarios,
which was the original intent and should be the only reason for that
method.

See gh-24635

Subject: [PATCH 0499/2315] ShallowEtagHeaderFilter checks for pre-existing
 eTag

The filter now checks for an explicitly set eTag and uses it instead of
generating one, and also suppresses caching.

Closes gh-24635

Subject: [PATCH 0519/2315] Add ServerRequest::checkNotModified

This commit adds the checkNotModified method to ServerRequest in both
WebFlux.fn and WebMvc.fn. Unlike other checkNotModified methods found
in the framework, this method does not return a boolean, but rather
a response wrapped in a Mono/Optional. If the resource has
not been changed, the not-modified response can be returned directly;
if the resource has changed, the user can create a corresponding
response using switchIfEmpty/orElse(Get).

Closes gh-24173

Subject: [PATCH 0530/2315] Improve RouterFunction composition

This commit changes the way two RouterFunctions are composed in
WebFlux.fn. Prior to this commit, two were composed with
`switchIfEmpty()`, switching from the first to the second route if the
first did not provide an element.
After this commit, two router functions are compose using `concat`,
which results in a smaller stack trace.

Subject: [PATCH 0531/2315] Improve efficiency of built RouterFunction

This commit changes the way RouterFunctions registered to the builder
are composed in both WebFlux.fn and WebMvc.fn.
Prior to this commit, all routes added to the build were composed with
`reduce`.
After this commit, all routes are stored in a special router function,
allowing for more efficient execution and smaller stack traces.

Subject: [PATCH 0546/2315] Include response body in
 UnknownHttpStatusCodeException

Spring Framework 5.2.2 introduced a regression in
DefaultResponseErrorHandler.handleError(ClientHttpResponse)
Specifically, for use cases where the InputStream had already been
consumed by the first invocation of getResponseBody(), the second
invocation of getResponseBody() resulted in the response body being
absent in the created UnknownHttpStatusCodeException.

This commit fixes this by invoking getResponseBody() only once in
DefaultResponseErrorHandler.handleError(ClientHttpReponse) in order to
reuse the retrieved response body for creating the exception message
and as a separate argument to the UnknownHttpStatusCodeException
constructor.

Closes gh-24595

Subject: [PATCH 0576/2315] Polish ConcurrentLruCache

This commit improves the performance of the `ConcurrentLruCache` and
applies a consistent style to the code:

* separating read/write locks into different variables does not help
performance, so this change is reverted
* apply a consistent style for read/write locks and try/cactch calls
* the reordering of recently used keys is only done when the cache is
full

Fixes gh-24671

Subject: [PATCH 0584/2315] Add @DynamicPropertySource support in TestContext
 framework

This commit introduces a @DynamicPropertySource annotation that can be
used on methods in test classes that want to add properties to the
Environment with a dynamically supplied value.

This new feature can be used in conjunction with Testcontainers and
other frameworks that manage resources outside the lifecycle of a
test's ApplicationContext.

Closes gh-24540

+/**
+ * Method-level annotation for integration tests that need to add properties with
+ * dynamic values to the {@code Environment}'s set of {@code PropertySources}.
+ *
+ * <p>This annotation and its supporting infrastructure were originally designed
+ * to allow properties from
+ * <a href="https://www.testcontainers.org/">Testcontainers</a> based tests to be
+ * exposed easily to Spring integration tests. However, this feature may also be
+ * used with any form of external resource whose lifecycle is maintained outside
+ * the test's {@code ApplicationContext}.
+ *
+ * <p>Methods annotated with {@code @DynamicPropertySource} must be {@code static}
+ * and must have a single {@link DynamicPropertyRegistry} argument which is used
+ * to add <em>name-value</em> pairs to the {@code Environment}'s set of
+ * {@code PropertySources}. Values are dynamic and provided via a {@link Supplier}
+ * which is only invoked when the property is resolved. Typically, method references
+ * are used to supply values, as in the following example.
+ *
+ * <h3>Example</h3>
+ *
+ * <pre class="code">

+===== Context Configuration with Dynamic Property Sources
+
+As of Spring Framework 5.2.5, the TestContext framework provides support for _dynamic_
+property sources via the `@DynamicPropertySource` annotation. This annotation can be used
+in integration tests that need to add properties with dynamic values to the set of
+`PropertySources` in the `Environment` for the `ApplicationContext` loaded for the
+integration test.
+
+NOTE: The `@DynamicPropertySource` annotation and its supporting infrastructure were
+originally designed to allow properties from
+https://www.testcontainers.org/[Testcontainers] based tests to be exposed easily to
+Spring integration tests. However, this feature may also be used with any form of
+external resource whose lifecycle is maintained outside the test's `ApplicationContext`.
+
+In contrast to the <<testcontext-ctx-management-property-sources,`@TestPropertySource`>>
+annotation that is applied at the class level, `@DynamicPropertySource` must be applied
+to a `static` method that accepts a single `DynamicPropertyRegistry` argument which is
+used to add _name-value_ pairs to the `Environment`. Values are dynamic and provided via
+a `Supplier` which is only invoked when the property is resolved. Typically, method
+references are used to supply values, as can be seen in the following example which uses
+the Testcontainers project to manage a Redis container outside of the Spring
+`ApplicationContext`. The IP address and port of the managed Redis container are made
+available to components within the test's `ApplicationContext` via the `redis.host` and
+`redis.port` properties. These properties can be injected into Spring-managed components
+via `@Value("${redis.host}")` and `@Value("${redis.port}")`, respectively.
+

Subject: [PATCH 0601/2315] Do not cache multipart MIME types in cache

Prior to this commmit, "mutipart/*" MIME types would be cached by the
`MimeTypeUtils` LRU cache. Since those MIME types are likely to have
random boundaries in them, they can waste space in the LRU cache.
This is not improving things since we're parsing them anyway.

This commit skips the caching step for all "multipart" MIME types.

Fixes gh-24767

Subject: [PATCH 0649/2315] Remove flaky check in MBeanClientInterceptorTests

Prior to this commit, the testTestLazyConnectionToRemote() method in
MBeanClientInterceptorTests expected an exception to be thrown while
attempting to access the state of a proxied MBean after the MBeanServer
had been shutdown; however, the test occasionally failed if the server
had not been properly shutdown.

Since an attempt to wait on the server to shutdown proved not to be
consistently helpful in this scenario, we are entirely removing this
check from the test.

Subject: [PATCH 0658/2315] Fix faulty tests

The tests were doing Callable async request processing in the main
thread which was already bound (via HandlerInterceptor#preProcess).
This leads to an ISE from TransactionSynchronizationManager#bindResource
but it went unnoticed because there is no Servlet container and no
async dispatch to continue processing.

-(that is, the other objects with which they work) only through constructor arguments, arguments
-to a factory method, or properties that are set on the object instance after it is
-constructed or returned from a factory method. The container then injects those
+(that is, the other objects with which they work) only through constructor arguments,
+arguments to a factory method, or properties that are set on the object instance after
+it is constructed or returned from a factory method. The container then injects those
 dependencies when it creates the bean. This process is fundamentally the inverse (hence
 the name, Inversion of Control) of the bean itself controlling the instantiation
 or location of its dependencies on its own by using direct construction of classes or

Subject: [PATCH 0672/2315] Consolidate TxMgr lookup tests in the TCF

This commit consolidates TransactionManager lookup tests in the Spring
TestContext Framework (TCF), migrates some to JUnit Jupiter, simplifies
their implementations, and removes duplicated test cases.

Subject: [PATCH 0673/2315] Test status quo for @Primary +
 TransactionManagementConfigurer in TCF

This commit introduces an integration test for the status quo in the
Spring TestContext Framework (TCF) for multiple transaction managers
registered as @Primary and via the TransactionManagementConfigurer API.

In Spring Framework 5.3 we will revise the transaction manager lookup in
TestContextTransactionUtils so that the transaction manager configured
via the TransactionManagementConfigurer API is favored over a @Primary
transaction manager.

See gh-24869

Subject: [PATCH 0674/2315] Document default constructor as fallback for
 non-@Autowired constructors

Prior to this commit, it was unclear in the documentation that a default
constructor will be used by default for autowiring if multiple
constructors are present and none of them is annotated with @Autowired.

This commit improves the documentation in this regard.

Closes gh-24838

Subject: [PATCH 0681/2315] Fix potential leak in MimeTypeUtils LRUCache

Prior to this commit, the `MimeTypeUtils` LRUCache would maintain a
queue to track least recently used cached values. In some cases,
concurrent access could create more entries in that unbounded queue than
expected and spend a significant amount of time removing entries in that
queue (i.e. iterating over a long list of elements).

This commit ensures that recently used entries are only added to the
queue if they've been removed by the current thread, in case of
concurrent access.

Fixes gh-24886

Subject: [PATCH 0695/2315] Retain brackets for IPV6 address in
 MockHttpServletRequest

According to the Javadoc for ServletRequest's getServerName() method,
when the `Host` header is set, the server name is "the value of the
part before ':' in the Host header value ...". For a value representing
an IPV6 address such as `[::ffff:abcd:abcd]`, the enclosing square
brackets should therefore not be stripped from the enclosed IPV6
address.

However, the changes made in conjunction with gh-16704 introduced a
regression in Spring Framework 4.1 for the getServerName() method in
MockHttpServletRequest by stripping the enclosing brackets from the
IPV6 address in the `Host` header. Similarly, the changes made in
conjunction with gh-20686 introduced a regression in Spring Framework
4.3.13 and 5.0.2 in the getRequestURL() method in
MockHttpServletRequest by delegating to the getServerName() method
which strips the enclosing brackets.

This commit fixes the implementation of getServerName() so that the
enclosing brackets are no longer stripped from an IPV6 address in the
`Host` header. The implementation of getRequestURL() is therefore also
fixed.

In addition, in order to avoid a NullPointerException, the
implementations of getServerName() and getServerPort() now assert that
an IPV6 address present in the `Host` header correctly contains an
opening and closing bracket and throw an IllegalStateException if that
is not the case.

Closes gh-24916

Subject: [PATCH 0709/2315] Avoid synthesizing annotations unnecessarily

Prior to Spring Framework 5.2, some of our annotation utilities would
not synthesize an annotation if it was already synthesized or not
synthesizable (i.e., did not declare local aliases via @AliasFor and
did not declare attributes that could override attributes in the
meta-annotation hierarchy above the given annotation); however, we lost
most of this functionality with the introduction of the new
MergedAnnotations API.

This commit revises the implementation of createSynthesized() in
TypeMappedAnnotation so that, for invocations of
MergedAnnotation.synthesize() and indirectly for invocations of
AnnotatedElementUtils.findMergedAnnotation(), etc.:

1. An annotation that was previously synthesized will not be
   synthesized again.

2. An annotation that is not "synthesizable" will not be synthesized.

For both of the above use cases, the original annotation is now
returned from createSynthesized().

Closes gh-24861

Subject: [PATCH 0713/2315] WARN against invalid patterns with
 PathPatternParser

As of gh-24952, `PathPatternParser` will strictly reject patterns with
`"**"` in the middle of them. `"**"` is only allowed at the end of the
pattern for matching multiple path segments until the end of the path.

Currently, if `"**"` is used in the middle of a pattern it will be
considered as a single `"*"` instead. Rejecting such cases should
clarify the situation.

This commit prepares for that upcoming change and:

* logs a warning message if such a case is used by an application
* expands the MVC and WebFlux documentation about URI matching in
general

Closes gh-24958

Subject: [PATCH 0715/2315] Avoid synthesizing annotations unnecessarily

Commit 31fa1569c5 introduced initial support for avoiding unnecessary
annotation synthesis in the MergedAnnotation API; however, it only
avoided synthesis for annotations that do not declare any attributes.

This commit reworks this support to avoid unnecessary annotation
synthesis for annotations that declare attributes.

Specifically, this commit introduces a new `isSynthesizable()` method
in AnnotationTypeMapping that allows the "synthesizable" flag to be
computed once and cached along with the other metadata already cached
in AnnotationTypeMapping instances. TypeMappedAnnotation now delegates
to this new method when determining whether it should synthesize an
annotation.

Closes gh-24861

Subject: [PATCH 0722/2315] Reintroduce synthesized annotation attribute value
 caching

Prior to the introduction of the MergedAnnotation API in Spring Framework
5.2, our SynthesizedAnnotationInvocationHandler utilized a cache for
annotation attribute values; whereas, the new
SynthesizedMergedAnnotationInvocationHandler has no such caching in
place.

Issues such as gh-24961 indicate a regression in performance caused by
the lack of such an attribute value cache. For example, the required
attribute in @RequestParam is looked up using the internal meta-model
in the MergedAnnotation API twice per request for each @RequestParam in
a given controller handler method.

This commit reintroduces the attribute value cache to avoid the
unnecessary performance overhead associated with multiple lookups of
the same attribute in a synthesized annotation. This applies not only
to direct attribute method invocations but also to invocations of
equals() and hashCode() on a synthesized annotation.

Note, however, that this commit does NOT address multiple lookups of
annotation attribute values for invocations of toString(). That behavior
currently remains unchanged in the implementation of
org.springframework.core.annotation.TypeMappedAnnotation.toString().

Closes gh-24970

Subject: [PATCH 0724/2315] Allow override of data binder binding

Motivation
----------
The Spring MVC ModelAttributeMethodProcessor includes many helpful
extension methods that allow developers to extend and enhance the data
binding capabilities of the class. Unfortunately, Spring WebFlux's
equivalent class, the ModelAttributeMethodArgumentResolver, does not
include these same extension methods. I am leveraging these extension
methods, specifically the bindRequestParameters method, to provide
valuable enhancements to my application. I would like to provide these
same enhancements to the WebFlux portion of my application and am
unable to do so at this time. I would like to update the WebFlux
ModelAttributeMethodArgumentResolver to add the bindRequestParameters
method.

Modifications
-------------
I created a new method called bindRequestParameters and encapsulated
the WebExchangeDataBinder bind call inside of it. This method is
marked as protected as it should only be used by children of this
class. This change mirrors the behavior in the equivalent Spring MVC
class (ModelAttributeMethodProcessor).

Result
------
The WebFlux ModelAttributeMethodArgumentResolver can now accept
alternative data binding implementations mirroring the Web MVC
behavior.

If set parent bean factory to self, once try to get an undefined bean,  bellow condition

will always be true and  StackOverflowError will be thrown.
Sometimes, this issue is hard to detect during runtime, if self-reference is not allowed here, error will be found at the early time of startup.
Also, a self-reference parent bean factory is valueless.

Subject: [PATCH 0735/2315] Optimize toString() for synthesized annotations

This commit moves the toString() implementation for synthesized
annotations from TypeMappedAnnotation to
SynthesizedMergedAnnotationInvocationHandler in order to take advantage
of the synthesized annotation attribute value cache introduced in
72b1abd226.

Closes gh-24970

Subject: [PATCH 0752/2315] Honor generic type information in
 BeanUtils.copyProperties()

Prior to this commit, BeanUtils.copyProperties() ignored generic type
information when comparing candidate source and target property types.

This commit reworks the implementation of BeanUtils.copyProperties() so
that generic type information is taken into account when copying
properties.

See gh-24281

Subject: [PATCH 0755/2315] Remove artifactory plugin from build

As we're moving the build to Concourse CI, we don't need to use the
Artifactory plugin anymore. Our build will publish the artifacts to a
repository on the local filesystem and will push its content to
Artifactory with the spring-io/artifactory-resource.

This commit also adds the conditional configuration for publishing to a
local repository.

Subject: [PATCH 0756/2315] Add Concourse Build pipeline

This commit adds the Concourse build infrastructure under the "ci/"
folder. It contains:

* "images/", the definitions of container images used in the pipeline
* "pipeline.yml" the build pipeline definition
* "parameters.yml" the parameters for the pipeline definition
* "tasks/" the tasks used by the build pipeline
* "scripts/" scripts used by pipeline tasks

This first iteration of the Concourse pipeline builds CI container
images for JDK8, JDK11, JDK14 and JDK15.
These images are used for building and publishing the master branch of
Spring Framework using JDK8. Other JDK variants are sanity checks and
don't actually publish the produced artifacts.

See gh-22490

+== Spring Framework Concourse pipeline
+
+The Spring Framework is using https://concourse-ci.org/[Concourse] for its CI build and other automated tasks.
+The Spring team has a dedicated Concourse instance available at https://ci.spring.io.
+
+=== Setting up your development environment
+
+If you're part of the Spring Framework project on GitHub, you can get access to CI management features.
+First, you need to go to https://ci.spring.io and install the client CLI for your platform (see bottom right of the screen).
+
+You can then login with the instance using:
+
+[source]
+----
+$ fly -t spring login -n spring-framework -c https://ci.spring.io
+----
+
+Once logged in, you should get something like:
+
+[source]
+----
+$ fly ts
+name                  url                   team                  expiry
+spring                https://ci.spring.io  spring-framework      Wed, 25 Mar 2020 17:45:26 UTC
+----
+
+=== Pipeline configuration and structure
+The build pipelines are described in `pipeline.yml` file.
+This file is listing Concourse resources, i.e. build inputs and outputs such as container images, artifact repositories, source repositories, notification services, etc.
+It also describes jobs (a job is a sequence of inputs, tasks and outputs); jobs are organized by groups.
+
+The `pipeline.yml` definition contains `((parameters))` which are loaded from the `parameters.yml` file or from our https://docs.cloudfoundry.org/credhub/[credhub instance].
+
+You'll find in this folder the following resources:
+* `pipeline.yml` the build pipeline
+* `parameters.yml` the build parameters used for the pipeline
+* `images/` holds the container images definitions used in this pipeline
+* `scripts/` holds the build scripts that ship within the CI container images
+* `tasks` contains the task definitions used in the main `pipeline.yml`
+
+=== Updating the build pipeline
+
+Updating files on the repository is not enough to update the build pipeline, as changes need to be applied.
+The pipeline can be deployed using the following command:
+
+[source]
+----
+$ fly -t spring set-pipeline -p spring-framework-5.3.x -c ci/pipeline.yml -l ci/parameters.yml
+----
+
+NOTE: This assumes that you have credhub integration configured with the appropriate secrets.

Subject: [PATCH 0766/2315] Filter out duplicates in SpringFactoriesLoader

Prior to this commit, SpringFactoriesLoader discovered all registered
factory implementations for a given factory type even if duplicates
were registered within a single META-INF/spring.factories file or in
multiple such files in the classpath.

This commit updates the internals of SpringFactoriesLoader so that
duplicate registrations are ignored, thereby aligning with the
well-known semantics for java.util.ServiceLoader in this regard.

Closes gh-24985

Subject: [PATCH 0774/2315] Fix Artifactory properties on published artifacts

This commit fixes the file pattern for the published zip artifacts.
Prior to this commit, the pattern was wrong and properties were not
applied to the published archives, preventing them from being published
automatically (javadoc, reference documentation, schemas...).

See gh-22490

Subject: [PATCH 0776/2315] Use same default ClassLoader in
 SpringFactoriesLoader

Prior to this commit, the loadFactoryNames() and loadFactories() methods
in SpringFactoriesLoader effectively used a different default
ClassLoader.

This commit ensures that the ClassLoader for SpringFactoriesLoader.class
is now consistently used as the default ClassLoader.

Closes gh-24992

Subject: [PATCH 0779/2315] Ensure that build directory exists before writing

This commit ensures that the build directory exists before writing the
build scan URL to it. This is useful when the `clean` task is executed
and the build folder is gone by the time the execution is done.

Subject: [PATCH 0782/2315] Move spring-framework.png to src/docs folder

Since the spring-framework.png file is not used in the generated
reference manual, this commit moves the spring-framework.png file from
the src/docs/asciidoc/images folder up to the src/docs folder.

Subject: [PATCH 0783/2315] Only include PNG files in reference manual

The `images` folder contains some files used to create the images, such
as OmniGraffle and SVG.

This commit modifies the `include` pattern to ensure that only `*.png`
files are copied from the source folder to the published reference
manual.

Subject: [PATCH 0790/2315] Support @TestConstructor config via JUnit Platform
 config param

This commit introduces support for setting the
spring.test.constructor.autowire.mode property via a JUnit Platform
configuration parameter -- for example, via the
junit-platform.properties file.

Closes gh-24285

Subject: [PATCH 0806/2315] Extend transaction attributes with labels

TransactionAttribute now exposes a labels attribute that associates a
descriptive array of labels with a transaction.

Labels may be of a pure descriptive nature or may get evaluated by
transaction managers to associate technology-specific behavior
with the actual transaction.

Subject: [PATCH 0809/2315] Fix concurrency issues in XStreamMarshaller

Prior to this commit, if an instance of XStreamMarshaller was used
concurrently from multiple threads without having first invoked the
afterPropertiesSet() method, the private `xstream` field could be
initialized multiple times resulting in a ConcurrentModificationException
in XStream's internal DefaultConverterLookup.

This commit fixes these concurrency issues by making the `xstream` field
volatile and by implementing a double-checked locking algorithm in
getXStream() to avoid concurrent instance creation.

Closes gh-25017

Subject: [PATCH 0813/2315] Add Release pipeline for Milestone versions

This commit finishes the first step for migrating our complete build and
release pipeline to Concourse CI.

We're creating here a new "Release" jobs group in our pipeline.
We can now release Milestones from our pipeline with:

* the "stage-milestone" job, which creates and tags a new Milestone
version on the source repository, builds the artifacts and deploys them
in a staging repository and updates the version to the next SNAPSHOT.

* the "promote-milestone" fetches the build information from the staging
repository and promotes the released milestone in the official milestone
repository.

Interactions with the Artifactory and Bintray REST APIs are done using
the https://github.com/spring-io/concourse-release-scripts project.

Closes gh-22490

+
+Imperative and reactive transaction management shares the same semantics for
+transaction boundary and transaction attribute definitions. The main difference
+to imperative transactions is the deferred nature. `TransactionInterceptor`
+decorates the returned reactive type with a transactional operator
+to begin and cleanup the transaction. Therefore, calling a transactional
+reactive method defers the actual transaction management to subscription
+type that activates processing of the reactive type.
+
+Another aspect of reactive transaction management relates to data escaping
+which is a natural consequence of the programming model.
+
+Method return values of imperative transactions are returned from transactional methods
+upon successful termination of a method so that partially computed results
+do not escape the method closure.
+
+Reactive transaction methods return a reactive wrapper type which represent a
+computation sequence along with a promise to begin and complete computation.
+
+A `Publisher` can emit data while an transaction is ongoing but not necessarily
+completed. Therefore, methods that depend upon successful completion of an entire
+transaction need to ensure completion and buffer results in the calling code.

+The `TransactionOperator` follows an operator design that is similar to other reactive

+code that is intention driven, in that your code focuses solely on what
+you want to do.

Subject: [PATCH 0824/2315] Honor TxMgmtConfigurer when @Primary tx mgr is
 present in TCF

Prior to this commit, the Spring TestContext Framework (TCF) favored a
@Primary transaction manger over one configured via the
TransactionManagementConfigurer API, and this contradicts the behavior
in production Spring applications.

This commit aligns the transaction manger lookup within the TCF so that
a transaction manger configured via the TransactionManagementConfigurer
API is properly favored over a @Primary transaction manager.

Closes gh-24869

Subject: [PATCH 0830/2315] Wrappers for native headers on the client side

Native server request headers have been wrapped rather than copied
since 5.1. This commit applies the same change to the client side
where, to make matters worse, headers were copied repeatedly on every
access, see also previous commit ca897b95.

For Netty and Jetty the wrappers are the same as on the server side
but duplicated in order to remain package private.

See gh-24680

Subject: [PATCH 0831/2315] Add mutate() to ClientResponse and deprecate from()

from() has the flaw of ignoring the body and it can't be fixed because
applications are guaranteed to be setting it already and if set twice
the builder drains the first body.

mutate() is a better fit in any case for what needs to be done in a
filter chain. It can be done more efficiently and is consistent with
similar options on the server side.

Subject: [PATCH 0832/2315] Shortcut handling of bodyToFlux(DataBuffer.class)

Given that the body is a Flux<DataBuffer> there probably could be a
Flux<DataBuffer> body();

At least bodyToFlux(DataBuffer.class) which is used when mutating and
is a common case should not incur overhead.

Subject: [PATCH 0833/2315] Avoid parse cookies when mutating request or
 response

When mutating a ServerHttpRequest or ClientResponse, the respective
builders no longer access cookies automatically which causes them to
be parsed and does so only if necessary. Likewise re-applying the
read-only HttpHeaders wrapper is avoided.

Subject: [PATCH 0835/2315] Align TransactionManagementConfigurer support in
 TCF with production

This commit picks up where 613bd3be1db254f713e39dafcf22f52686611cd7
left off by ensuring that a transaction manager configured via the
TransactionManagementConfigurer API takes precedence over any
transaction manager configured as a bean in the ApplicationContext
unless @Transactional is configured with a qualifier for the explicit
transaction manager to use in tests.

Closes gh-24869

Subject: [PATCH 0837/2315] Reject "/path/**/other" patterns in
 PathPatternParser

Prior to this commit, patterns like `"/path/**/other"` would be treated
as `"/path/*/other"` (single wildcard, i.e. matching zero to many chars
within a path segment). This will not match multiple segments, as
expected by `AntPathMatcher` users or by `PathPatternParser` users when
in patterns like `"/resource/**"`.

This commit now rejects patterns like `"/path/**/other"` as invalid.
This behavior was previously warned against since gh-24958.

Closes gh-24952

Subject: [PATCH 0838/2315] Use weak ETags in VersionResourceResolver

Prior to this commit, the `VersionResourceResolver` implementations
would write a strong ETag HTTP response header with the resolved version
of the resource (the actual value depending on the chosen strategy).

This approach doesn't work well when combined with HTTP compression.
Web servers disable HTTP response copression in the presence of strong
ETags since mutating the response body would break the contract.

This commit changes this semantic and ensures that weak ETags are used
instead.

Closes gh-24898

Subject: [PATCH 0841/2315] Only proxy supported beans in
 BeanNameAutoProxyCreator

Prior to this commit, if a BeanNameAutoProxyCreator was configured with
a custom TargetSourceCreator, the TargetSourceCreator was applied to
all beans in the ApplicationContext. Thus, the list of supported
beanNames was effectively ignored when applying any
TargetSourceCreator. Consequently, if a TargetSourceCreator returned a
non-null TargetSource for a given bean, the BeanNameAutoProxyCreator
proxied the bean even if the bean name had not been configured in the
beanNames list.

This commit addresses this issue by ensuring that a custom
TargetSourceCreator is only applied to beans whose names match the
configured beanNames list in a BeanNameAutoProxyCreator.

Closes gh-24915

Subject: [PATCH 0860/2315] Add JMH benchmark infrastructure

Prior to this commit, the Spring Framework test suite would rely only on
"Performance" tests associated with a specific CI build. As outlined in
gh-24830, the way they're built and executed is not working well
anymore.

This commit introduces a new JMH benchmark infrastructure in the build.
The goal here is not to run those benchmarks as part of a CI build, but
rather provide a proper infrastructure for writing and locally running
micro-benchmarks when working on specific optimizations.

This commit adds and configures a Gradle JMH plugin to allow for JMH
benchmark classes in Spring Framework modules (in `src/jmh/java` of each
`spring-*` module). It's also relaxing the checkstyle rules for JMH
classes, especially around Javadoc rules: this code is not meant to
have Javadocs.

Finally, this commit links to a new Wiki page on the project GitHub
repository documenting the infrastructure and helping contributors to
run and design benchmarks.

See gh-24830

Subject: [PATCH 0861/2315] Optimize MediaType parsing

Prior to this commit, `MediaType.parseMediaType` would already rely on
the internal LRU cache in `MimeTypeUtils` for better performance. With
that optimization, the parsing of raw media types is skipped for cached
elements.
But still, `MediaType.parseMediaType` would first get a cached
`MimeType` instance from that cache and then instantiate a
`new MediaType(type, subtype, parameters)`. This constructor not only
replays the `MimeType` checks on type/subtyme tokens and parameters, but
it also performs `MediaType`-specific checks on parameters.
Such checks are not required, as we're using an existing `MimeType`
instance in the first place.

This commit adds a new protected copy constructor (skipping checks) in
`MimeType` and uses it in `MediaType.parseMediaType` as a result.

This yields interesting performance improvements, with +400% throughput
and -40% allocation/call in benchmarks. This commit also introduces a
new JMH benchmark for future optimization work.

Closes gh-24769

Subject: [PATCH 0874/2315] Avoid using regex matching for static patterns

Prior to this commit (and the previous one), the `AntPathStringMatcher`
(inner class of `AntPathmatcher`) would compile `Pattern` instances and
use regex matching even for static patterns such as `"/home"`.

This change introduces a shortcut in the string matcher algorithm to
skip the `Pattern` creation and uses `String` equality instead.
Static patterns are quite common in applications and this change can
bring performance improvements, depending on the mix of patterns
configured in the web application.

In benchmarks (added with this commit), we're seeing +20% throughput
and -40% allocation. This of course can vary depending on the number of
static patterns configured in the application.

Closes gh-24887

Subject: [PATCH 0885/2315] Shared read-only instance of UrlPathHelper

In many places UrlPathHelper is created and used without any
customizations, in some cases repeatedly. This commit adds a
shared read-only UrlPathHelper instance with default settings.

See gh-25100

Subject: [PATCH 0890/2315] Fix
 ExceptionHandlerExceptionResolver.setResponseBodyAdvice behaviour

Prior to this commit, calling the `setResponseBodyAdvice` method would
clear all existing `ResponseBodyAdvice` instances present in the list
before adding provided one.
This behavior is inconsistent with the Javadoc and other
implementations.

This brings the method in line with the existing documentation.

Subject: [PATCH 0892/2315] Honor attributes configured in ServerRequest.from()
 builder

Prior to this commit, if attributes were configured in the builder
returned by `ServerRequest.from(...)`, those attributes were not
available in the `ServerRequest` built by the builder. In addition, any
attributes in the original `ServerRequest` supplied to
`ServerRequest.from(...)` were also ignored.

This commit addresses this issue by ensuring that the attributes
configured via DefaultServerRequestBuilder are used as the attributes
in the resulting `ServerRequest`.

This commit also polishes the Javadoc in `ServerRequest` and
`ClientResponse` and avoids the use of lambda expressions in the
constructors for `DefaultServerRequestBuilder` and
`DefaultClientResponseBuilder`.

Closes gh-25106

Subject: [PATCH 0904/2315] Add dependency on BouncyCastle for JDK 15+

With a recent upgrade to an early access build for JDK 15,
ServerHttpsRequestIntegrationTests began failing since Netty's
SelfSignedCertificate could not be properly initialized.

This commit adds a test fixture dependency on BouncyCastle which is now
needed by Netty's SelfSignedCertificate on JDK 15 or higher, since JDK 15
no longer supports the javax.security.cert.X509Certificate.

See: https://bugs.openjdk.java.net/browse/JDK-8241039

Subject: [PATCH 0923/2315] Fix BaseCodecConfigurer clone bug

Prior to this commit, ExchangeStrategies custom codec's reader and
writer were not registered due to a bug in BaseCodecConfigurer.

This commit fixes this by correcting the implementation of the
DefaultCustomCodecs constructor used within BaseCodecConfigurer.

Closes gh-25149

Subject: [PATCH 0926/2315] Make use of custom types configurable in
 YamlProcessor

Prior to this commit, there was no easy way to restrict what types could
be loaded from a YAML document in subclasses of YamlProcessor such as
YamlPropertiesFactoryBean and YamlMapFactoryBean.

This commit introduces a setSupportedTypes(Class<?>...) method in
YamlProcessor in order to address this. If no supported types are
configured, all types encountered in YAML documents will be supported.
If an unsupported type is encountered, an IllegalStateException will be
thrown when the corresponding YAML node is processed.

Closes gh-25152

Subject: [PATCH 0950/2315] Respect MediaType charset in Jackson converters

Before this commit, AbstractJackson2HttpMessageConverter and subclasses
did not check media type encoding in the canRead and canWrite
methods. As a result, the converter reported that it can write
(for instance) "application/json;charset=ISO-8859-1", but in practice
wrote the default charset (UTF-8).

This commit fixes that bug.

See: gh-25076

Subject: [PATCH 0951/2315] Respect MimeType charset in Jackson codecs

Before this commit, Jackson2CodecSupport and subclasses
did not check media type encoding in the supportsMimeType
method (called from canEncode/canDecode).
As a result, the encoder reported that it can write
(for instance) "application/json;charset=ISO-8859-1", but in practice
wrote the default charset (UTF-8).

This commit fixes that bug.

Closes: gh-25076

Subject: [PATCH 0954/2315] Respect MimeType charset in Jackson codecs

Before this commit, Jackson2CodecSupport and subclasses
did not check media type encoding in the supportsMimeType
method (called from canEncode/canDecode).
As a result, the encoder reported that it can write
(for instance) "application/json;charset=ISO-8859-1", but in practice
wrote the default charset (UTF-8).

This commit fixes that bug.

Closes: gh-25076

Subject: [PATCH 0956/2315] Test status quo for invocation order of all advice
 types

Prior to this commit we did not have tests in place to verify the status
quo for the invocation order of all advice types when declared within
a single aspect, either via the <aop:aspect> XML namespace or AspectJ
auto-proxy support.

This commit introduces such tests that demonstrate where such ordering
is broken or suboptimal.

The only test for which the advice invocation order is correct or at
least as expected is the afterAdviceTypes() test method in
ReflectiveAspectJAdvisorFactoryTests, where an AOP proxy is hand crafted
using ReflectiveAspectJAdvisorFactory without the use of Spring's
AspectJPrecedenceComparator.

See gh-25186

Subject: [PATCH 0971/2315] Implement reliable advice invocation order within
 an @Aspect

The AspectJPrecedenceComparator was designed to mimic the precedence
order enforced by the AspectJ compiler with regard to multiple 'after'
methods defined within the same aspect whose pointcuts match the same
joinpoint. Specifically, if an aspect declares multiple @After,
@AfterReturning, or @AfterThrowing advice methods whose pointcuts match
the same joinpoint, such 'after' advice methods should be invoked in
the reverse order in which they are declared in the source code.

When the AspectJPrecedenceComparator was introduced in Spring Framework
2.0, it achieved its goal of mimicking the AspectJ compiler since the
JDK at that time (i.e., Java 5) ensured that an invocation of
Class#geDeclaredMethods() returned an array of methods that matched the
order of declaration in the source code. However, Java 7 removed this
guarantee. Consequently, in Java 7 or higher,
AspectJPrecedenceComparator no longer works as it is documented or as
it was designed when sorting advice methods in a single @Aspect class.
Note, however, that AspectJPrecedenceComparator continues to work as
documented and designed when sorting advice configured via the
<aop:aspect> XML namespace element.

PR gh-24673 highlights a use case where AspectJPrecedenceComparator
fails to assign the highest precedence to an @After advice method
declared last in the source code. Note that an @After advice method
with a precedence higher than @AfterReturning and @AfterThrowing advice
methods in the same aspect will effectively be invoked last due to the
try-finally implementation in AspectJAfterAdvice.invoke() which invokes
proceed() in the try-block and invokeAdviceMethod() in the
finally-block.

Since Spring cannot reliably determine the source code declaration
order of annotated advice methods without using ASM to analyze the byte
code, this commit introduces reliable invocation order for advice
methods declared within a single @Aspect. Specifically, the
getAdvisors(...) method in ReflectiveAspectJAdvisorFactory now hard
codes the declarationOrderInAspect to `0` instead of using the index of
the current advice method. This is necessary since the index no longer
has any correlation to the method declaration order in the source code.
The result is that all advice methods discovered via reflection will
now be sorted only according to the precedence rules defined in the
ReflectiveAspectJAdvisorFactory.METHOD_COMPARATOR. Specifically, advice
methods within a single @Aspect will be sorted in the following order
(with @After advice methods effectively invoked after @AfterReturning
and @AfterThrowing advice methods): @Around, @Before, @After,
@AfterReturning, @AfterThrowing.

The modified assertions in AspectJAutoProxyAdviceOrderIntegrationTests
demonstrate the concrete effects of this change.

Closes gh-25186

+===== Cancel Signals
+
+In Reactive Streams, a `Subscriber` can cancel its `Subscription` and terminate its
+`Publisher`. Operators in Project Reactor, as well as in other libraries, such as `next()`,
+`take(long)`, `timeout(Duration)`, and others can issue cancellations. There is no way to
+know the reason for the cancellation, whether it is due to an error or a simply lack of
+interest to consume further, and in version 5.2 the `TransactionalOperator` defaults to
+committing the transaction on cancel. In version 5.3 this behavior will change and
+transactions will be roll back on cancel to create a reliable and deterministic outcome.
+As a result it is important to consider the operators used downstream from a transaction
+`Publisher`. In particular in the case of a `Flux` or other multi-value `Publisher`,
+the full output must be consumed to allow the transaction to complete.

+[NOTE]
+====
+As of Spring Framework 5.2.7, advice methods defined in the same `@Aspect` class that
+need to run at the same join point are assigned precedence based on their advice type in
+the following order, from highest to lowest precedence: `@Around`, `@Before`, `@After`,
+`@AfterReturning`, `@AfterThrowing`. Note, however, that due to the implementation style
+in Spring's `AspectJAfterAdvice`, an `@After` advice method will effectively be invoked
+after any `@AfterReturning` or `@AfterThrowing` advice methods in the same aspect.

+====
+In contrast to the precedence rules for advice methods defined in the same `@Aspect`
+class, when two pieces of advice defined in the same `<aop:aspect>` element both need to
+run at the same join point, the precedence is determined by the order in which the advice

+
+For example, given an `around` advice and a `before` advice defined in the same

Prior to this commit, Jaxb2XmlDecoder and XmlEventDecoder threw
XMLStreamExceptions instead of DecodingExceptions (as the Decoder
contract defines).

This commit resolves this issue.

Closes: gh-24778

Subject: [PATCH 1003/2315] Ensure spring-core JAR is reproducible

Prior to this commit, a change to Javadoc in any class in spring-core
would result in ALL tests in the entire test suite being re-run via the
Gradle build.

Thanks to a tip from @melix, this commit ensures that the spring-core
JAR is "reproducible".

Subject: [PATCH 1011/2315] Convert non-unicode input when reading w/ Jackson

This commit makes sure that Jackson-based message converters and
decoders can deal with non-unicode input. It does so by reading
non-unicode input messages with a InputStreamReader.

This commit also adds additional tests forthe canRead/canWrite methods
on both codecs and message converters.

Subject: [PATCH 1012/2315] Support user-defined key type in JDBC KeyHolder

Prior to this commit, the JDBC KeyHolder API only supported keys of
type Number. However, a generated key can be a UUID or something else,
and developers shouldn't have to go manually through complex
collections to access it.

This commit adds a new getKeyAs(Class<T> keyType) method to the
KeyHolder API that allows the user to specify the key type.

Closes gh-24655

Subject: [PATCH 1014/2315] Upgrade to Kotlin 1.4 M2

- The compiler is configured to retain compatibility with Kotlin 1.3.
- Explicit API mode is not yet enabled but could be in the future.
- A workaround for Gradle build is required for now, see
  https://youtrack.jetbrains.com/issue/KT-39610 for more details.
- Some exceptions thrown by Kotlin have changed to NullPointerException,
  see https://youtrack.jetbrains.com/issue/KT-22275 for more details.

Closes gh-24171

Subject: [PATCH 1015/2315] Make DispatcherServlet.properties loading lazy

With #25209, DispatcherServlet.properties loading and parsing
will be useless for most of use cases, and it requires
configuration on GraalVM native images.

The purpose of this issue to make such loading and parsing lazy,
only invoked in getDefaultStrategies() if needed.

Subject: [PATCH 1027/2315] Rollback reactive transaction on cancel

This commit introduces a change in reactive transaction semantics for
cancel signals. Canceling a subscription now rolls back a reactive transaction
to achieve a deterministic transaction outcome.

Previously, cancel signals committed a transaction which could
cause partially committed transactions depending on when the cancel happened.

+ * Spring classes such as {@code DatabaseClient} use this strategy implicitly.
+ * If not used in combination with this transaction manager, the

+ *
+ * <p>Alternatively, you can allow application code to work with the standard

+ * Obviously, this is not multi-threading capable.
+ *
+ * <p>Note that at shutdown, someone should close the underlying
+ * Connection via the {@code close()} method. Client code will
+ * never call close on the Connection handle if it is
+ * SmartConnectionFactory-aware (e.g. uses
+ * {@link ConnectionFactoryUtils#releaseConnection(Connection, ConnectionFactory)}).
+ *
+ * <p>If client code will call {@link Connection#close()} in the
+ * assumption of a pooled Connection, like when using persistence tools,
+ * set "suppressClose" to "true". This will return a close-suppressing
+ * proxy instead of the physical Connection.
+ *
+ * <p>This is primarily intended for testing and pipelining usage of connections.
+ * For example, it enables easy testing outside an application server, for code
+ * that expects to work on a {@link ConnectionFactory}.
+ * Note that this implementation does not act as a connection pool-like utility.
+ * Connection pooling requires a {@link ConnectionFactory} implemented by e.g.
+ * {@code r2dbc-pool}.

+ * Proxy for a target R2DBC {@link ConnectionFactory}, adding awareness
+ * of Spring-managed transactions.
+ *
+ * <p>Data access code that should remain unaware of Spring's data access
+ * support can work with this proxy to seamlessly participate in
+ * Spring-managed transactions.
+ * Note that the transaction manager, for example {@link R2dbcTransactionManager},
+ * still needs to work with the underlying {@link ConnectionFactory},
+ * <i>not</i> with this proxy.
+ *
+ * <p><b>Make sure that {@link TransactionAwareConnectionFactoryProxy} is the outermost
+ * {@link ConnectionFactory} of a chain of {@link ConnectionFactory} proxies/adapters.</b>
+ * {@link TransactionAwareConnectionFactoryProxy} can delegate either directly to the
+ * target connection pool or to some intermediary proxy/adapter.
+ *
+ * <p>Delegates to {@link ConnectionFactoryUtils} for automatically participating
+ * in thread-bound transactions, for example managed by {@link R2dbcTransactionManager}.
+ * {@link #create()} calls and {@code close} calls on returned {@link Connection}
+ * will behave properly within a transaction, i.e. always operate on the
+ * transactional Connection. If not within a transaction, normal {@link ConnectionFactory}
+ * behavior applies.
+ *
+ * <p> This proxy allows data access code to work with the plain R2DBC API. However,
+ * if possible, use Spring's {@link ConnectionFactoryUtils} or {@code DatabaseClient}
+ * to get transaction participation even without a proxy for the target
+ * {@link ConnectionFactory}, avoiding the need to define such a proxy in the first place.
+ *
+ * <p><b>NOTE:</b> This {@link ConnectionFactory} proxy needs to return wrapped
+ * {@link Connection}s (which implement the {@link ConnectionProxy} interface) in order
+ * to handle close calls properly. Use {@link Wrapped#unwrap()} to retrieve
+ * the native R2DBC Connection.

+[[r2dbc]]
+== Data Access with R2DBC
+
+https://r2dbc.io[R2DBC] ("Reactive Relational Database Connectivity") is a community-driven
+specification effort to standardize access to SQL databases using reactive patterns.
+
+
+[[r2dbc-packages]]
+=== Package Hierarchy
+
+The Spring Framework's R2DBC abstraction framework consists of two different packages:
+
+* `core`: The `org.springframework.r2dbc.core` package contains the `DatabaseClient`
+class plus a variety of related classes. See <<r2dbc-core>>.
+
+* `connection`: The `org.springframework.r2dbc.connection` package contains a utility class
+for easy `ConnectionFactory` access and various simple `ConnectionFactory` implementations
+that you can use for testing and running unmodified R2DBC. See <<r2dbc-connections>>.
+
+
+[[r2dbc-core]]
+=== Using the R2DBC Core Classes to Control Basic R2DBC Processing and Error Handling
+
+This section covers how to use the R2DBC core classes to control basic R2DBC processing,
+including error handling. It includes the following topics:
+
+* <<r2dbc-DatabaseClient>>
+* <<r2dbc-DatabaseClient-examples-statement>>
+* <<r2dbc-DatabaseClient-examples-query>>
+* <<r2dbc-DatabaseClient-examples-update>>
+* <<r2dbc-DatbaseClient-filter>>
+* <<r2dbc-auto-generated-keys>>
+
+[[r2dbc-DatabaseClient]]
+==== Using `DatabaseClient`
+
+`DatabaseClient` is the central class in the R2DBC core package. It handles the
+creation and release of resources, which helps to avoid common errors, such as
+forgetting to close the connection. It performs the basic tasks of the core R2DBC
+workflow (such as statement creation and execution), leaving application code to provide
+SQL and extract results. The `DatabaseClient` class:
+
+* Runs SQL queries
+* Update statements and stored procedure calls
+* Performs iteration over `Result` instances
+* Catches R2DBC exceptions and translates them to the generic, more informative, exception
+hierarchy defined in the `org.springframework.dao` package. (See <<dao-exceptions>>.)
+
+The client has a functional, fluent API using reactive types for declarative composition.
+
+When you use the `DatabaseClient` for your code, you need only to implement
+`java.util.function` interfaces, giving them a clearly defined contract.
+Given a `Connection` provided by the `DatabaseClient` class, a `Function`
+callback creates a `Publisher`. The same is true for mapping functions that
+extract a `Row` result.
+
+You can use `DatabaseClient` within a DAO implementation through direct instantiation
+with a `ConnectionFactory` reference, or you can configure it in a Spring IoC container
+and give it to DAOs as a bean reference.
+
+The simplest way to create a `DatabaseClient` object is through a static factory method, as follows:
+
+[source,java,indent=0,subs="verbatim,quotes",role="primary"]
+.Java
+----
+	DatabaseClient client = DatabaseClient.create(connectionFactory);
+----
+[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
+.Kotlin
+----
+	val client = DatabaseClient.create(connectionFactory)
+----
+
+NOTE: The `ConnectionFactory` should always be configured as a bean in the Spring IoC
+container.
+
+The preceding method creates a `DatabaseClient` with default settings.
+
+You can also obtain a `Builder` instance from `DatabaseClient.builder()`.
+You can customize the client by calling the following methods:
+
+* `….bindMarkers(…)`: Supply a specific `BindMarkersFactory` to configure named
+parameter to database bind marker translation.
+* `….executeFunction(…)`: Set the `ExecuteFunction` how `Statement` objects get
+ executed.
+* `….namedParameters(false)`: Disable named parameter expansion. Enabled by default.
+
+TIP: Dialects are resolved by {api-spring-framework}/r2dbc/core/binding/BindMarkersFactoryResolver.html[`BindMarkersFactoryResolver`]
+ from a `ConnectionFactory`, typically by inspecting `ConnectionFactoryMetadata`.
+ +
+You can let Spring auto-discover your `BindMarkersFactory` by registering a
+class that implements `org.springframework.r2dbc.core.binding.BindMarkersFactoryResolver$BindMarkerFactoryProvider`
+through `META-INF/spring.factories`.
+`BindMarkersFactoryResolver` discovers bind marker provider implementations from
+the class path using Spring's `SpringFactoriesLoader`.
+ +
+
+Currently supported databases are:
+
+* H2
+* MariaDB
+* Microsoft SQL Server
+* MySQL
+* Postgres
+
+All SQL issued by this class is logged at the `DEBUG` level under the category
+corresponding to the fully qualified class name of the client instance (typically
+`DefaultDatabaseClient`). Additionally, each execution registers a checkpoint in
+the reactive sequence to aid debugging.
+
+The following sections provide some examples of `DatabaseClient` usage. These examples
+are not an exhaustive list of all of the functionality exposed by the `DatabaseClient`.
+See the attendant {api-spring-framework}/r2dbc/core/DatabaseClient.html[javadoc] for that.
+
+[[r2dbc-DatabaseClient-examples-statement]]
+===== Executing Statements
+
+`DatabaseClient` provides the basic functionality of running a statement.
+The following example shows what you need to include for minimal but fully functional
+code that creates a new table:
+
+[source,java,indent=0,subs="verbatim,quotes",role="primary"]
+.Java
+----
+	Mono<Void> completion = client.sql("CREATE TABLE person (id VARCHAR(255) PRIMARY KEY, name VARCHAR(255), age INTEGER);")
+	        .then();
+----
+[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
+.Kotlin
+----
+	client.sql("CREATE TABLE person (id VARCHAR(255) PRIMARY KEY, name VARCHAR(255), age INTEGER);")
+	        .await()
+----
+
+`DatabaseClient` is designed for convenient, fluent usage.
+It exposes intermediate, continuation, and terminal methods at each stage of the
+execution specification. The preceding example above uses `then()` to return a completion
+`Publisher` that completes as soon as the query (or queries, if the SQL query contains
+multiple statements) completes.
+
+NOTE: `execute(…)` accepts either the SQL query string or a query `Supplier<String>`
+to defer the actual query creation until execution.
+
+[[r2dbc-DatabaseClient-examples-query]]
+===== Querying (`SELECT`)
+
+SQL queries can return values through `Row` objects or the number of affected rows.
+`DatabaseClient` can return the number of updated rows or the rows themselves,
+depending on the issued query.
+
+The following query gets the `id` and `name` columns from a table:
+
+[source,java,indent=0,subs="verbatim,quotes",role="primary"]
+.Java
+----
+	Mono<Map<String, Object>> first = client.sql("SELECT id, name FROM person")
+	        .fetch().first();
+----
+[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
+.Kotlin
+----
+	val first = client.sql("SELECT id, name FROM person")
+	        .fetch().awaitFirst()
+----
+
+The following query uses a bind variable:
+
+[source,java,indent=0,subs="verbatim,quotes",role="primary"]
+.Java
+----
+	Mono<Map<String, Object>> first = client.sql("SELECT id, name FROM person WHERE first_name = :fn")
+	        .bind("fn", "Joe")
+	        .fetch().first();
+----
+[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
+.Kotlin
+----
+	val first = client.sql("SELECT id, name FROM person WHERE WHERE first_name = :fn")
+	        .bind("fn", "Joe")
+	        .fetch().awaitFirst()
+----
+
+You might have noticed the use of `fetch()` in the example above. `fetch()` is a
+continuation operator that lets you specify how much data you want to consume.
+
+Calling `first()` returns the first row from the result and discards remaining rows.
+You can consume data with the following operators:
+
+* `first()` return the first row of the entire result. Its Kotlin Coroutine variant
+is named `awaitFirst()` for non-nullable return values and `awaitFirstOrNull()`
+if the value is optional.
+* `one()` returns exactly one result and fails if the result contains more rows.
+Using Kotlin Coroutines, `awaitOne()` for exactly one value or `awaitOneOrNull()`
+if the value may be `null`.
+* `all()` returns all rows of the result. When using Kotlin Coroutines, use `flow()`.
+* `rowsUpdated()` returns the number of affected rows (`INSERT`/`UPDATE`/`DELETE`
+count). Its Kotlin Coroutine variant is named `awaitRowsUpdated()`.
+
+Without specifying further mapping details, queries return tabular results
+as `Map` whose keys are case-insensitive column names that map to their column value.
+
+You can take control over result mapping by supplying a `Function<Row, T>` that gets
+called for each `Row` so it can can return arbitrary values (singular values,
+collections and maps, and objects).
+
+The following example extracts the `id` column and emits its value:
+
+[source,java,indent=0,subs="verbatim,quotes",role="primary"]
+.Java
+----
+	Flux<String> names = client.sql("SELECT name FROM person")
+	        .map(row -> row.get("id", String.class))
+	        .all();
+----
+[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
+.Kotlin
+----
+	val names = client.sql("SELECT name FROM person")
+	        .map{ it.get("id", String.class) }
+	        .flow()
+----
+
+
+[[r2dbc-DatabaseClient-mapping-null]]
+.What about `null`?
+****
+Relational database results can contain `null` values.
+The Reactive Streams specification forbids the emission of `null` values.
+That requirement mandates proper `null` handling in the extractor function.
+While you can obtain `null` values from a `Row`, you must not emit a `null`
+value. You must wrap any `null` values in an object (for example, `Optional`
+for singular values) to make sure a `null` value is never returned directly
+by your extractor function.
+****
+
+[[r2dbc-DatabaseClient-examples-update]]
+===== Updating (`INSERT`, `UPDATE`, and `DELETE`) with `DatabaseClient`
+
+The only difference of modifying statements is that these statements typically
+do not return tabular data so you use `rowsUpdated()` to consume results.
+
+The following example shows an `UPDATE` statement that returns the number
+of updated rows:
+
+[source,java,indent=0,subs="verbatim,quotes",role="primary"]
+.Java
+----
+	Mono<Integer> affectedRows = client.sql("UPDATE person SET first_name = :fn")
+	        .bind("fn", "Joe")
+	        .fetch().rowsUpdated();
+----
+[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
+.Kotlin
+----
+	val affectedRows = client.sql("UPDATE person SET first_name = :fn")
+	        .bind("fn", "Joe")
+	        .fetch().awaitRowsUpdated()
+----
+
+[[r2dbc-DatabaseClient-named-parameters]]
+===== Binding Values to Queries
+
+A typical application requires parameterized SQL statements to select or
+update rows according to some input. These are typically `SELECT` statements
+constrained by a `WHERE` clause or `INSERT` and `UPDATE` statements that accept
+input parameters. Parameterized statements bear the risk of SQL injection if
+parameters are not escaped properly. `DatabaseClient` leverages R2DBC's
+`bind` API to eliminate the risk of SQL injection for query parameters.
+You can provide a parameterized SQL statement with the `execute(…)` operator
+and bind parameters to the actual `Statement`. Your R2DBC driver then executes
+the statement by using prepared statements and parameter substitution.
+
+Parameter binding supports two binding strategies:
+
+* By Index, using zero-based parameter indexes.
+* By Name, using the placeholder name.
+
+The following example shows parameter binding for a query:
+
+====
+[source,java]
+----
+db.sql("INSERT INTO person (id, name, age) VALUES(:id, :name, :age)")
+    .bind("id", "joe")
+    .bind("name", "Joe")
+    .bind("age", 34);
+----
+====
+
+.R2DBC Native Bind Markers
+****
+R2DBC uses database-native bind markers that depend on the actual database vendor.
+As an example, Postgres uses indexed markers, such as `$1`, `$2`, `$n`.
+Another example is SQL Server, which uses named bind markers prefixed with `@`.
+
+This is different from JDBC, which requires `?` as bind markers.
+In JDBC, the actual drivers translate `?` bind markers to database-native
+markers as part of their statement execution.
+
+Spring Framework's R2DBC support lets you use native bind markers or named bind
+markers with the `:name` syntax.
+
+Named parameter support leverages a `BindMarkersFactory` instance to expand named
+parameters to native bind markers at the time of query execution, which gives you
+a certain degree of query portability across various database vendors.
+****
+
+The query-preprocessor unrolls named `Collection` parameters into a series of bind
+markers to remove the need of dynamic query creation based on the number of arguments.
+Nested object arrays are expanded to allow usage of (for example) select lists.
+
+Consider the following query:
+
+[source,sql]
+----
+SELECT id, name, state FROM table WHERE (name, age) IN (('John', 35), ('Ann', 50))
+----
+
+The preceding query can be parametrized and executed as follows:
+
+[source,java,indent=0,subs="verbatim,quotes",role="primary"]
+.Java
+----
+	List<Object[]> tuples = new ArrayList<>();
+	tuples.add(new Object[] {"John", 35});
+	tuples.add(new Object[] {"Ann",  50});
+
+	client.sql("SELECT id, name, state FROM table WHERE (name, age) IN (:tuples)")
+	    .bind("tuples", tuples);
+----
+[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
+.Kotlin
+----
+	val tuples: MutableList<Array<Any>> = ArrayList()
+	tuples.add(arrayOf("John", 35))
+	tuples.add(arrayOf("Ann", 50))
+
+	client.sql("SELECT id, name, state FROM table WHERE (name, age) IN (:tuples)")
+	    .bind("tuples", tuples)
+----
+
+NOTE: Usage of select lists is vendor-dependent.
+
+The following example shows a simpler variant using `IN` predicates:
+
+[source,java,indent=0,subs="verbatim,quotes",role="primary"]
+.Java
+----
+	client.sql("SELECT id, name, state FROM table WHERE age IN (:ages)")
+	    .bind("ages", Arrays.asList(35, 50));
+----
+[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
+.Kotlin
+----
+	val tuples: MutableList<Array<Any>> = ArrayList()
+	tuples.add(arrayOf("John", 35))
+	tuples.add(arrayOf("Ann", 50))
+
+	client.sql("SELECT id, name, state FROM table WHERE age IN (:ages)")
+	    .bind("tuples", arrayOf(35, 50))
+----

+Sometimes it you need to fine-tune options on the actual `Statement`
+before it gets executed. Register a `Statement` filter
+(`StatementFilterFunction`) through `DatabaseClient` to intercept and
+modify statements in their execution, as the following example shows:
+
+[source,java,indent=0,subs="verbatim,quotes",role="primary"]
+.Java
+----
+	client.sql("INSERT INTO table (name, state) VALUES(:name, :state)")
+	    .filter((s, next) -> next.execute(s.returnGeneratedValues("id")))
+	    .bind("name", …)
+	    .bind("state", …);
+----
+[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
+.Kotlin
+----
+	client.sql("INSERT INTO table (name, state) VALUES(:name, :state)")
+				.filter { s: Statement, next: ExecuteFunction -> next.execute(s.returnGeneratedValues("id")) }
+				.bind("name", …)
+				.bind("state", …)
+----
+
+`DatabaseClient` exposes also simplified `filter(…)` overload accepting `Function<Statement, Statement>`:
+
+[source,java,indent=0,subs="verbatim,quotes",role="primary"]
+.Java
+----
+	client.sql("INSERT INTO table (name, state) VALUES(:name, :state)")
+	    .filter(statement -> s.returnGeneratedValues("id"));
+
+	client.sql("SELECT id, name, state FROM table")
+	    .filter(statement -> s.fetchSize(25));
+----
+[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
+.Kotlin
+----
+	client.sql("INSERT INTO table (name, state) VALUES(:name, :state)")
+	    .filter { statement -> s.returnGeneratedValues("id") }
+
+	client.sql("SELECT id, name, state FROM table")
+	    .filter { statement -> s.fetchSize(25) }
+----
+
+`StatementFilterFunction` implementations allow filtering of the executed 
+`Statement` and filtering of `Result` objects.
+
+[[r2dbc-DatabaseClient-idioms]]
+===== `DatabaseClient` Best Practices
+
+Instances of the `DatabaseClient` class are thread-safe, once configured. This is
+important because it means that you can configure a single instance of a `DatabaseClient`
+and then safely inject this shared reference into multiple DAOs (or repositories).
+The `DatabaseClient` is stateful, in that it maintains a reference to a `ConnectionFactory`,
+but this state is not conversational state.
+
+A common practice when using the `DatabaseClient` class is to configure a `ConnectionFactory`
+in your Spring configuration file and then dependency-inject
+that shared `ConnectionFactory` bean into your DAO classes. The `DatabaseClient` is created in
+the setter for the `ConnectionFactory`. This leads to DAOs that resemble the following:
+
+[source,java,indent=0,subs="verbatim,quotes",role="primary"]
+.Java
+----
+	public class R2dbcCorporateEventDao implements CorporateEventDao {
+
+		private DatabaseClient databaseClient;
+
+		public void setConnectionFactory(ConnectionFactory connectionFactory) {
+			this.databaseClient = DatabaseClient.create(connectionFactory);
+		}
+
+		// R2DBC-backed implementations of the methods on the CorporateEventDao follow...
+	}
+----
+[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
+.Kotlin
+----
+	class R2dbcCorporateEventDao(connectionFactory: ConnectionFactory) : CorporateEventDao {
+
+		private val databaseClient = DatabaseClient.create(connectionFactory)
+
+		// R2DBC-backed implementations of the methods on the CorporateEventDao follow...
+	}
+----
+
+An alternative to explicit configuration is to use component-scanning and annotation
+support for dependency injection. In this case, you can annotate the class with `@Component`
+(which makes it a candidate for component-scanning) and annotate the `ConnectionFactory` setter
+method with `@Autowired`. The following example shows how to do so:
+
+[source,java,indent=0,subs="verbatim,quotes",role="primary"]
+.Java
+----
+	@Component // <1>
+	public class R2dbcCorporateEventDao implements CorporateEventDao {
+
+		private DatabaseClient databaseClient;
+
+		@Autowired // <2>
+		public void setConnectionFactory(ConnectionFactory connectionFactory) {
+			this.databaseClient = DatabaseClient.create(connectionFactory); // <3>
+		}
+
+		// R2DBC-backed implementations of the methods on the CorporateEventDao follow...
+	}
+----
+<1> Annotate the class with `@Component`.
+<2> Annotate the `ConnectionFactory` setter method with `@Autowired`.
+<3> Create a new `DatabaseClient` with the `ConnectionFactory`.
+
+[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
+.Kotlin
+----
+	@Component // <1>
+	class R2dbcCorporateEventDao(connectionFactory: ConnectionFactory) : CorporateEventDao { // <2>
+
+		private val databaseClient = DatabaseClient(connectionFactory) // <3>
+
+		// R2DBC-backed implementations of the methods on the CorporateEventDao follow...
+	}
+----
+<1> Annotate the class with `@Component`.
+<2> Constructor injection of the `ConnectionFactory`.
+<3> Create a new `DatabaseClient` with the `ConnectionFactory`.
+
+Regardless of which of the above template initialization styles you choose to use (or
+not), it is seldom necessary to create a new instance of a `DatabaseClient` class each
+time you want to run SQL. Once configured, a `DatabaseClient` instance is thread-safe.
+If your application accesses multiple
+databases, you may want multiple `DatabaseClient` instances, which requires multiple
+`ConnectionFactory` and, subsequently, multiple differently configured `DatabaseClient`
+instances.
+
+[[r2dbc-auto-generated-keys]]
+== Retrieving Auto-generated Keys
+
+`INSERT` statements may generate keys when inserting rows into a table
+that defines an auto-increment or identity column. To get full control over
+the column name to generate, simply register a `StatementFilterFunction` that
+requests the generated key for the desired column.
+
+[source,java,indent=0,subs="verbatim,quotes",role="primary"]
+.Java
+----
+	Mono<Integer> generatedId = client.sql("INSERT INTO table (name, state) VALUES(:name, :state)")
+	    .filter(statement -> s.returnGeneratedValues("id"))
+			.map(row -> row.get("id", Integer.class))
+			.first();
+
+	// generatedId emits the generated key once the INSERT statement has finished
+----
+[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
+.Kotlin
+----
+	val generatedId = client.sql("INSERT INTO table (name, state) VALUES(:name, :state)")
+	    .filter { statement -> s.returnGeneratedValues("id") }
+			.map { row -> row.get("id", Integer.class) }
+			.awaitOne()
+
+	// generatedId emits the generated key once the INSERT statement has finished
+----

+* <<r2dbc-SingleConnectionFactory>>
+* <<r2dbc-TransactionAwareConnectionFactoryProxy>>
+* <<r2dbc-R2dbcTransactionManager>>
+
+
+[[r2dbc-ConnectionFactory]]
+==== Using `ConnectionFactory`
+
+Spring obtains an R2DBC connection to the database through a `ConnectionFactory`.
+A `ConnectionFactory` is part of the R2DBC specification and is a common entry-point
+for drivers. It lets a container or a framework hide connection pooling
+and transaction management issues from the application code. As a developer,
+you need not know details about how to connect to the database. That is the
+responsibility of the administrator who sets up the `ConnectionFactory`. You
+most likely fill both roles as you develop and test code, but you do not
+necessarily have to know how the production data source is configured.
+
+When you use Spring's R2DBC layer, you can can configure your own with a
+connection pool implementation provided by a third party. A popular
+implementation is R2DBC Pool (`r2dbc-pool`). Implementations in the Spring 
+distribution are meant only for testing purposes and do not provide pooling.
+
+To configure a `ConnectionFactory`:
+
+. Obtain a connection with `ConnectionFactory` as you typically obtain an R2DBC `ConnectionFactory`.
+. Provide an R2DBC URL
+(See the documentation for your driver for the correct value).
+
+The following example shows how to configure a `ConnectionFactory`:
+
+[source,java,indent=0,subs="verbatim,quotes",role="primary"]
+.Java
+----
+	ConnectionFactory factory = ConnectionFactories.get("r2dbc:h2:mem:///test?options=DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE");
+----
+[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
+.Kotlin
+----
+	val factory = ConnectionFactories.get("r2dbc:h2:mem:///test?options=DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE");
+----
+
+
+[[r2dbc-ConnectionFactoryUtils]]
+==== Using `ConnectionFactoryUtils`
+
+
+The `ConnectionFactoryUtils` class is a convenient and powerful helper class
+that provides `static` methods to obtain connections from `ConnectionFactory`
+and close connections (if necessary).
+
+It supports subscriber ``Context``-bound connections with, for example
+`R2dbcTransactionManager`.
+
+
+[[r2dbc-SingleConnectionFactory]]
+==== Using `SingleConnectionFactory`
+
+The `SingleConnectionFactory` class is an implementation of `DelegatingConnectionFactory`
+interface that wraps a single `Connection` that is not closed after each use.
+
+If any client code calls `close` on the assumption of a pooled connection (as when using
+persistence tools), you should set the `suppressClose` property to `true`. This setting
+returns a close-suppressing proxy that wraps the physical connection. Note that you can
+no longer cast this to a native `Connection` or a similar object.
+
+`SingleConnectionFactory` is primarily a test class and may be used for specific requirements
+such as pipelining if your R2DBC driver permits for such use.
+In contrast to a pooled `ConnectionFactory`, it reuses the same connection all the time, avoiding
+excessive creation of physical connections.
+
+
+[[r2dbc-TransactionAwareConnectionFactoryProxy]]
+==== Using `TransactionAwareConnectionFactoryProxy`
+
+`TransactionAwareConnectionFactoryProxy` is a proxy for a target `ConnectionFactory`.
+The proxy wraps that target `ConnectionFactory` to add awareness of Spring-managed transactions.
+
+NOTE: Using this class is required if you use a R2DBC client that is not integrated otherwise
+with Spring's R2DBC support. In this case, you can still use this client and, at
+the same time, have this client participating in Spring managed transactions. It is generally
+preferable to integrate a R2DBC client with proper access to `ConnectionFactoryUtils`
+for resource management.
+
+See the {api-spring-framework}/r2dbc/connection/TransactionAwareConnectionFactoryProxy.html[`TransactionAwareConnectionFactoryProxy`]
+javadoc for more details.
+
+
+[[r2dbc-R2dbcTransactionManager]]
+==== Using `R2dbcTransactionManager`
+
+The `R2dbcTransactionManager` class is a `ReactiveTransactionManager` implementation for
+single R2DBC datasources. It binds an R2DBC connection from the specified connection factory
+to the subscriber `Context`, potentially allowing for one subscriber connection for each 
+connection factory.
+
+Application code is required to retrieve the R2DBC connection through
+`ConnectionFactoryUtils.getConnection(ConnectionFactory)`, instead of R2DBC's standard
+`ConnectionFactory.create()`.
+
+All framework classes (such as `DatabaseClient`) use this strategy implicitly.
+If not used with this transaction manager, the lookup strategy behaves exactly like the common one.
+Thus, it can be used in any case.
+
+The `R2dbcTransactionManager` class supports custom isolation levels that get applied to the connection.

Subject: [PATCH 1037/2315] Align DispatcherServlet defaults for Java and XML

Prior to this commit some of the default strategies defined
for the DispatcherServlet weren't included in the default
configuration for both Java and XML configuration.

The following default beans have been added to the configuration
with the name as expected by the DispatcherServlet:

- org.springframework.web.servlet.i18n.AcceptHeaderLocaleResolver
- org.springframework.web.servlet.theme.FixedThemeResolver
- org.springframework.web.servlet.support.SessionFlashMapManager
- org.springframework.web.servlet.view.DefaultRequestToViewNameTranslator

Closes gh-25209

Subject: [PATCH 1038/2315] Support multi-value X-Forwarded-Prefix headers

Prior to this commit, the Forwarded headers for Spring MVC and Spring
WebFlux did not support multiple prefix values for the
`"X-Forwarded-Prefix"` HTTP header.

This commit splits and processes multiple prefixes defined in the
dedicated header.

Closes gh-25254

Subject: [PATCH 1042/2315] Provide a flag to disable SpEL support

This commit introduces a spring.spel.ignore system property
which when set to true avoid initializing SpEL infrastructure.

A typical use case is optimizing GraalVM native image footprint
for applications not using SpEL. In order to be effective, those
classes should be initialized at build time:

- org.springframework.context.support.AbstractApplicationContext
- org.springframework.core.SpringProperties
- org.springframework.context.event.EventListenerMethodProcessor

Closes gh-25153

-Captured URI variables can be accessed with `@PathVariable`, as the following example shows:
+`@RequestMapping` methods can be mapped using URL patterns. There are two alternatives:
+
+* `PathPattern` -- a pre-parsed pattern matched against the URL path also pre-parsed as
+`PathContainer`. Designed for web use, this solution deals effectively with encoding and
+path parameters, and matches efficiently.
+* `AntPathMatcher` -- match String patterns against a String path. This is the original
+solution also used in Spring configuration to select resources on the classpath, on the
+filesystem, and other locations. It is less efficient and the String path input is a
+challenge for dealing effectively with encoding and other issues with URLs.
+
+`PathPattern` is the recommended solution for web applications and it is the only choice in
+Spring WebFlux. Prior to version 5.3, `AntPathMatcher` was the only choice in Spring MVC
+and continues to be the default. However `PathPattern` can be enabled in the
+<<mvc-config-path-matching, MVC config>>.
+
+`PathPattern` supports the same pattern syntax as `AntPathMatcher`. In addition it also
+supports the capturing pattern, e.g. `+{*spring}+`, for matching 0 or more path segments
+at the end of a path. `PathPattern` also restricts the use of `+**+` for matching multiple
+path segments such that it's only allowed at the end of a pattern. This eliminates many
+cases of ambiguity when choosing the best matching pattern for a given request.
+For full pattern syntax please refer to
+{api-spring-framework}/web/util/pattern/PathPattern.html[PathPattern] and
+{api-spring-framework}/util/AntPathMatcher.html[AntPathMatcher].
+
+Some example patterns:
+
+* `+"/resources/ima?e.png"+` - match one character in a path segment
+* `+"/resources/*.png"+` - match zero or more characters in a path segment
+* `+"/resources/**"+` - match multiple path segments
+* `+"/projects/{project}/versions"+` - match a path segment and capture it as a variable
+* `+"/projects/{project:[a-z]+}/versions"+` - match and capture a variable with a regex
+
+Captured URI variables can be accessed with `@PathVariable`. For example:

 ==== Pattern Comparison
 [.small]#<<web-reactive.adoc#webflux-ann-requestmapping-pattern-comparison, WebFlux>>#
 
-When multiple patterns match a URL, they must be compared to find the best match. This is done
-by using `AntPathMatcher.getPatternComparator(String path)`, which looks for patterns that are more
-specific.
+When multiple patterns match a URL, the best match must be selected. This is done with
+one of the following depending on whether parsed `PathPattern`'s are enabled for use or not:
 
-A pattern is less specific if it has a lower count of URI variables (counted as 1), single
-wildcards (counted as 1), and double wildcards (counted as 2). Given an equal score, the
-longer pattern is chosen. Given the same score and length, the pattern with more URI variables
-than wildcards is chosen.
+* {api-spring-framework}/web/util/pattern/PathPattern.html#SPECIFICITY_COMPARATOR[`PathPattern.SPECIFICITY_COMPARATOR`]
+* {api-spring-framework}/util/AntPathMatcher.html#getPatternComparator-java.lang.String-[`AntPathMatcher.getPatternComparator(String path)`]
+
+Both help to sorts patterns with more specific ones on top. A pattern is less specific if
+it has a lower count of URI variables (counted as 1), single wildcards (counted as 1),
+and double wildcards (counted as 2). Given an equal score, the longer pattern is chosen.
+Given the same score and length, the pattern with more URI variables than wildcards is
+chosen.
 
 The default mapping pattern (`/{asterisk}{asterisk}`) is excluded from scoring and always
 sorted last. Also, prefix patterns (such as `/public/{asterisk}{asterisk}`) are considered less

Subject: [PATCH 1045/2315] Provide a flag to disable XML support

This commit introduces a spring.xml.ignore system property
which when set to true avoid initializing XML infrastructure.

A typical use case is optimizing GraalVM native image footprint
for applications not using XML. In order to be effective, those
classes should be initialized at build time:

- org.springframework.util.DefaultPropertiesPersister
- org.springframework.core.io.support.PropertiesLoaderUtils
- org.springframework.web.servlet.function.support.RouterFunctionMapping
- org.springframework.web.client.RestTemplate
- org.springframework.web.servlet.mvc.method.annotation.ExceptionHandlerExceptionResolver
- org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport
- org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter
- org.springframework.http.converter.support.AllEncompassingFormHttpMessageConverter
- org.springframework.http.codec.support.BaseDefaultCodecs
- org.springframework.beans.PropertyEditorRegistrySupport

Closes gh-25151

Subject: [PATCH 1047/2315] Fix missing sslInfo with Reactor Netty and http/2

Prior to this commit, the `SslInfo` would be missing for WebFlux apps
when deployed on Reactor Netty with http/2.

This commit ensures that the request adapter checks the current channel
and the parent channel for the presence of the `SslHander`.
In the case of http/2, the `SslHander` is tied to the parent channel.

Fixes gh-25278

-== JCA CCI
-
-Java EE provides a specification to standardize access to enterprise information systems
-(EIS): the JCA (Java EE Connector Architecture). This specification is divided into
-two different parts:
-
-* SPI (Service Provider Interfaces) that the connector provider must implement. These
-  interfaces constitute a resource adapter that can be deployed on a Java EE
-  application server. In such a scenario, the server manages connection pooling,
-  transactions, and security (managed mode). The application server is also responsible
-  for managing the configuration, which is held outside the client application. A
-  connector can be used without an application server as well. In this case, the
-  application must configure it directly (non-managed mode).
-* CCI (Common Client Interface) that an application can use to interact with the
-  connector and, thus, communicate with an EIS. An API for local transaction demarcation
-  is provided as well.
-
-The aim of the Spring CCI support is to provide classes to access a CCI connector in
-typical Spring style, using the Spring Framework's general resource and transaction
-management facilities.
-
-NOTE: The client side of connectors does not always use CCI. Some connectors expose their own
-APIs, providing a JCA resource adapter to use the system contracts of a Java EE container
-(connection pooling, global transactions, and security). Spring does not offer special
-support for such connector-specific APIs.
-
-
-
-[[cci-config]]
-=== Configuring CCI
-
-This section covers how to configure a Common Client Interface (CCI). It includes the
-following topics:
-
-* <<cci-config-connector>>
-* <<cci-config-connectionfactory>>
-* <<cci-config-cci-connections>>
-* <<cci-config-single-connection>>
-
-
-[[cci-config-connector]]
-==== Connector Configuration
-
-The base resource to use JCA CCI is the `ConnectionFactory` interface. The connector
-you use must provide an implementation of this interface.
-
-To use your connector, you can deploy it on your application server and fetch the
-`ConnectionFactory` from the server's JNDI environment (managed mode). The connector
-must be packaged as a RAR file (resource adapter archive) and contain a `ra.xml` file to
-describe its deployment characteristics. The actual name of the resource is specified
-when you deploy it. To access it within Spring, you can use Spring's
-`JndiObjectFactoryBean` or `<jee:jndi-lookup>` to fetch the factory by its JNDI name.
-
-Another way to use a connector is to embed it in your application (non-managed mode) and
-not use an application server to deploy and configure it. Spring offers the
-possibility to configure a connector as a bean, through a `FactoryBean` implementation called
-(`LocalConnectionFactoryBean`). In this manner, you only need the connector library in
-the classpath (no RAR file and no `ra.xml` descriptor needed). The library must be
-extracted from the connector's RAR file, if necessary.
-
-Once you have access to your `ConnectionFactory` instance, you can inject it into
-your components. These components can either be coded against the plain CCI API or
-use Spring's support classes for CCI access (e.g. `CciTemplate`).
-
-NOTE: When you use a connector in non-managed mode, you cannot use global transactions, because
-the resource is never enlisted or delisted in the current global transaction of the
-current thread. The resource is not aware of any global Java EE transactions that
-might be running.
-
-
-[[cci-config-connectionfactory]]
-==== `ConnectionFactory` Configuration in Spring
-
-To make connections to the EIS, you need to obtain a `ConnectionFactory` from
-the application server (if you are in a managed mode) or directly from Spring (if you are
-in a non-managed mode).
-
-In managed mode, you can access a `ConnectionFactory` from JNDI. Its properties are
-configured in the application server. The following example shows how to do so:
-
-[source,xml,indent=0]
-[subs="verbatim,quotes"]
-----
-	<jee:jndi-lookup id="eciConnectionFactory" jndi-name="eis/cicseci"/>
-----
-
-In non-managed mode, you must configure the `ConnectionFactory` you want to use in the
-configuration of Spring as a JavaBean. The `LocalConnectionFactoryBean` class offers
-this setup style, passing in the `ManagedConnectionFactory` implementation of your
-connector, exposing the application-level CCI `ConnectionFactory`. The following example
-shows how to do so:
-
-[source,xml,indent=0]
-[subs="verbatim,quotes"]
-----
-	<bean id="eciManagedConnectionFactory" class="com.ibm.connector2.cics.ECIManagedConnectionFactory">
-		<property name="serverName" value="TXSERIES"/>
-		<property name="connectionURL" value="tcp://localhost/"/>
-		<property name="portNumber" value="2006"/>
-	</bean>
-
-	<bean id="eciConnectionFactory" class="org.springframework.jca.support.LocalConnectionFactoryBean">
-		<property name="managedConnectionFactory" ref="eciManagedConnectionFactory"/>
-	</bean>
-----
-
-NOTE: You cannot directly instantiate a specific `ConnectionFactory`. You need to go through
-the corresponding implementation of the `ManagedConnectionFactory` interface for your
-connector. This interface is part of the JCA SPI specification.
-
-
-[[cci-config-cci-connections]]
-==== Configuring CCI Connections
-
-JCA CCI lets you configure the connections to the EIS by using the
-`ConnectionSpec` implementation of your connector. To configure its properties,
-you need to wrap the target connection factory with a dedicated adapter,
-`ConnectionSpecConnectionFactoryAdapter`. You can configure the dedicated `ConnectionSpec`
-with the `connectionSpec` property (as an inner bean).
-
-This property is not mandatory, because the CCI `ConnectionFactory` interface defines two
-different methods to obtain a CCI connection. You can often configure some of the `ConnectionSpec` properties
-in the application server (in managed mode) or on the
-corresponding local `ManagedConnectionFactory` implementation. The following listing
-shows the relevant parts of the `ConnectionFactory` interface definition:
-
-[source,java,indent=0]
-[subs="verbatim,quotes"]
-----
-	public interface ConnectionFactory implements Serializable, Referenceable {
-		...
-		Connection getConnection() throws ResourceException;
-		Connection getConnection(ConnectionSpec connectionSpec) throws ResourceException;
-		...
-	}
-----
-
-Spring provides a `ConnectionSpecConnectionFactoryAdapter` that lets you specify a
-`ConnectionSpec` instance to use for all operations on a given factory. If the adapter's
-`connectionSpec` property is specified, the adapter uses the `getConnection` variant
-with the `ConnectionSpec` argument. Otherwise, the adapter uses the variant without that argument.
-The following example shows how to configure a `ConnectionSpecConnectionFactoryAdapter`:
-
-[source,xml,indent=0]
-[subs="verbatim,quotes"]
-----
-	<bean id="managedConnectionFactory"
-			class="com.sun.connector.cciblackbox.CciLocalTxManagedConnectionFactory">
-		<property name="connectionURL" value="jdbc:hsqldb:hsql://localhost:9001"/>
-		<property name="driverName" value="org.hsqldb.jdbcDriver"/>
-	</bean>
-
-	<bean id="targetConnectionFactory"
-			class="org.springframework.jca.support.LocalConnectionFactoryBean">
-		<property name="managedConnectionFactory" ref="managedConnectionFactory"/>
-	</bean>
-
-	<bean id="connectionFactory"
-			class="org.springframework.jca.cci.connection.ConnectionSpecConnectionFactoryAdapter">
-		<property name="targetConnectionFactory" ref="targetConnectionFactory"/>
-		<property name="connectionSpec">
-			<bean class="com.sun.connector.cciblackbox.CciConnectionSpec">
-				<property name="user" value="sa"/>
-				<property name="password" value=""/>
-			</bean>
-		</property>
-	</bean>
-----
-
-
-[[cci-config-single-connection]]
-==== Using a Single CCI Connection
-
-If you want to use a single CCI connection, Spring provides a further
-`ConnectionFactory` adapter to manage this. The `SingleConnectionFactory` adapter class
-lazily opens a single connection and closes it when this bean is destroyed at
-application shutdown. This class exposes special `Connection` proxies that behave
-accordingly, all sharing the same underlying physical connection. The following example
-shows how to use the `SingleConnectionFactory` adapter class:
-
-[source,xml,indent=0]
-[subs="verbatim,quotes"]
-----
-	<bean id="eciManagedConnectionFactory"
-			class="com.ibm.connector2.cics.ECIManagedConnectionFactory">
-		<property name="serverName" value="TEST"/>
-		<property name="connectionURL" value="tcp://localhost/"/>
-		<property name="portNumber" value="2006"/>
-	</bean>
-
-	<bean id="targetEciConnectionFactory"
-			class="org.springframework.jca.support.LocalConnectionFactoryBean">
-		<property name="managedConnectionFactory" ref="eciManagedConnectionFactory"/>
-	</bean>
-
-	<bean id="eciConnectionFactory"
-			class="org.springframework.jca.cci.connection.SingleConnectionFactory">
-		<property name="targetConnectionFactory" ref="targetEciConnectionFactory"/>
-	</bean>
-----
-
-NOTE: This `ConnectionFactory` adapter cannot directly be configured with a `ConnectionSpec`.
-You can use an intermediary `ConnectionSpecConnectionFactoryAdapter` that the
-`SingleConnectionFactory` talks to if you require a single connection for a specific
-`ConnectionSpec`.
-
-
-
-[[cci-using]]
-=== Using Spring's CCI Access Support
-
-This section describes how to use Spring's support for CCI to achieve various purposes.
-It includes the following topics:
-
-* <<cci-record-creator>>
-* <<cci-using-template>>
-* <<cci-using-dao>>
-* <<automatic-output-generation>>
-* <<template-summary>>
-* <<cci-straight>>
-* <<cci-template-example>>
-
-
-[[cci-record-creator]]
-==== Record Conversion
-
-One of the aims of Spring's JCA CCI support is to provide convenient facilities for
-manipulating CCI records. You can specify the strategy to create records and extract
-data from records, for use with Spring's `CciTemplate`. The interfaces described in
-this section configure the strategy to use input and output records if you do not want
-to work with records directly in your application.
-
-To create an input `Record`, you can use a dedicated implementation of the `RecordCreator`
-interface. The following listing shows the `RecordCreator` interface definition:
-
-[source,java,indent=0]
-[subs="verbatim,quotes"]
-----
-	public interface RecordCreator {
-
-		Record createRecord(RecordFactory recordFactory) throws ResourceException, DataAccessException;
-
-	}
-----
-
-The `createRecord(..)` method receives a `RecordFactory` instance as a
-parameter, which corresponds to the `RecordFactory` of the `ConnectionFactory` used.
-You can use this reference to create `IndexedRecord` or `MappedRecord` instances. The
-following sample shows how to use the `RecordCreator` interface and indexed or mapped
-records:
-
-[source,java,indent=0]
-[subs="verbatim,quotes"]
-----
-	public class MyRecordCreator implements RecordCreator {
-
-		public Record createRecord(RecordFactory recordFactory) throws ResourceException {
-			IndexedRecord input = recordFactory.createIndexedRecord("input");
-			input.add(new Integer(id));
-			return input;
-		}
-
-	}
-----
-
-You can use an output `Record` to receive data back from the EIS. Hence, you can pass a specific
-implementation of the `RecordExtractor` interface to Spring's
-`CciTemplate` to extract data from the output `Record`. The following listing shows the
-`RecordExtractor` interface definition:
-
-[source,java,indent=0]
-[subs="verbatim,quotes"]
-----
-	public interface RecordExtractor {
-
-		Object extractData(Record record) throws ResourceException, SQLException, DataAccessException;
-
-	}
-----
-
-The following example shows how to use the `RecordExtractor` interface:
-
-[source,java,indent=0]
-[subs="verbatim,quotes"]
-----
-	public class MyRecordExtractor implements RecordExtractor {
-
-		public Object extractData(Record record) throws ResourceException {
-			CommAreaRecord commAreaRecord = (CommAreaRecord) record;
-			String str = new String(commAreaRecord.toByteArray());
-			String field1 = string.substring(0,6);
-			String field2 = string.substring(6,1);
-			return new OutputObject(Long.parseLong(field1), field2);
-		}
-
-	}
-----
-
-
-[[cci-using-template]]
-==== Using `CciTemplate`
-
-The `CciTemplate` is the central class of the core CCI support package (
-`org.springframework.jca.cci.core`). It simplifies the use of CCI, since it handles the
-creation and release of resources. This helps to avoid common errors, such as forgetting to
-always close the connection. It cares for the lifecycle of connection and interaction
-objects, letting application code focus on generating input records from application
-data and extracting application data from output records.
-
-The JCA CCI specification defines two distinct methods to call operations on an EIS. The
-CCI `Interaction` interface provides two execute method signatures, as the following
-listing shows:
-
-[source,java,indent=0]
-[subs="verbatim,quotes"]
-----
-	public interface javax.resource.cci.Interaction {
-
-		...
-
-		boolean execute(InteractionSpec spec, Record input, Record output) throws ResourceException;
-
-		Record execute(InteractionSpec spec, Record input) throws ResourceException;
-
-		...
-
-	}
-----
-
-Depending on the template method called, `CciTemplate` knows which `execute` method
-to call on the interaction. In any case, a correctly initialized `InteractionSpec`
-instance is mandatory.
-
-You can use `CciTemplate.execute(..)` in two ways:
-
-* With direct `Record` arguments. In this case, you need to pass in the CCI input
-  record, and the returned object is the corresponding CCI output record.
-* With application objects, by using record mapping. In this case, you need to provide
-  corresponding `RecordCreator` and `RecordExtractor` instances.
-
-With the first approach, the following methods (which directly correspond to those on the
-`Interaction` interface) of the template are used:
-
-[source,java,indent=0]
-[subs="verbatim,quotes"]
-----
-	public class CciTemplate implements CciOperations {
-
-		public Record execute(InteractionSpec spec, Record inputRecord)
-				throws DataAccessException { ... }
-
-		public void execute(InteractionSpec spec, Record inputRecord, Record outputRecord)
-				throws DataAccessException { ... }
-
-	}
-----
-
-With the second approach, we need to specify the record creation and record
-extraction strategies as arguments. The interfaces used are those describe in the
-<<cci-record-creator, previous section on record conversion>>. The following
-listing shows the corresponding `CciTemplate` methods:
-
-[source,java,indent=0]
-[subs="verbatim,quotes"]
-----
-	public class CciTemplate implements CciOperations {
-
-		public Record execute(InteractionSpec spec,
-				RecordCreator inputCreator) throws DataAccessException {
-			// ...
-		}
-
-		public Object execute(InteractionSpec spec, Record inputRecord,
-				RecordExtractor outputExtractor) throws DataAccessException {
-			// ...
-		}
-
-		public Object execute(InteractionSpec spec, RecordCreator creator,
-				RecordExtractor extractor) throws DataAccessException {
-			// ...
-		}
-
-	}
-----
-
-Unless the `outputRecordCreator` property is set on the template (see the following
-section), every method calls the corresponding `execute` method of the CCI
-`Interaction` with two parameters: `InteractionSpec` and an input `Record`. It receives an
-output `Record` as its return value.
-
-`CciTemplate` also provides methods to create `IndexRecord` and `MappedRecord` outside of a
-`RecordCreator` implementation, through its `createIndexRecord(..)` and
-`createMappedRecord(..)` methods. You can use this within DAO implementations to create
-`Record` instances to pass into corresponding `CciTemplate.execute(..)` methods.
-The following listing shows the `CciTemplate` interface definition:
-
-[source,java,indent=0]
-[subs="verbatim,quotes"]
-----
-	public class CciTemplate implements CciOperations {
-
-		public IndexedRecord createIndexedRecord(String name) throws DataAccessException { ... }
-
-		public MappedRecord createMappedRecord(String name) throws DataAccessException { ... }
-
-	}
-----
-
-
-[[cci-using-dao]]
-==== Using DAO Support
-
-Spring's CCI support provides an abstract class for DAOs, supporting injection of a
-`ConnectionFactory` or a `CciTemplate` instance. The name of the class is
-`CciDaoSupport`. It provides simple `setConnectionFactory` and `setCciTemplate` methods.
-Internally, this class creates a `CciTemplate` instance for a passed-in
-`ConnectionFactory`, exposing it to concrete data access implementations in subclasses.
-The following example shows how to use `CciDaoSupport`:
-
-[source,java,indent=0]
-[subs="verbatim,quotes"]
-----
-	public abstract class CciDaoSupport {
-
-		public void setConnectionFactory(ConnectionFactory connectionFactory) {
-			// ...
-		}
-
-		public ConnectionFactory getConnectionFactory() {
-			// ...
-		}
-
-		public void setCciTemplate(CciTemplate cciTemplate) {
-			// ...
-		}
-
-		public CciTemplate getCciTemplate() {
-			// ...
-		}
-
-	}
-----
-
-
-[[automatic-output-generation]]
-==== Automatic Output Record Generation
-
-If the connector you use supports only the `Interaction.execute(..)` method with input and
-output records as parameters (that is, it requires the desired output record to be passed
-in instead of returning an appropriate output record), you can set the `outputRecordCreator`
-property of the `CciTemplate` to automatically generate an output record to be filled by
-the JCA connector when the response is received. This record is then returned to the caller
-of the template.
-
-This property holds an implementation of the <<cci-record-creator, `RecordCreator` interface>>,
-to be used for that purpose. You must directly specify the `outputRecordCreator` property on
-the `CciTemplate`. The following example shows how to do so:
-
-[source,java,indent=0]
-[subs="verbatim,quotes"]
-----
-	cciTemplate.setOutputRecordCreator(new EciOutputRecordCreator());
-----
-
-Alternatively (and we recommend this approach), in the Spring configuration, if the
-`CciTemplate` is configured as a dedicated bean instance, you can define beans in the
-following fashion:
-
-[source,xml,indent=0]
-[subs="verbatim,quotes"]
-----
-	<bean id="eciOutputRecordCreator" class="eci.EciOutputRecordCreator"/>
-
-	<bean id="cciTemplate" class="org.springframework.jca.cci.core.CciTemplate">
-		<property name="connectionFactory" ref="eciConnectionFactory"/>
-		<property name="outputRecordCreator" ref="eciOutputRecordCreator"/>
-	</bean>
-----
-
-NOTE: As the `CciTemplate` class is thread-safe, it is usually configured as a shared
-instance.
-
-
-[[template-summary]]
-==== `CciTemplate` `Interaction` Summary

-[[cci-straight]]
-==== Using a CCI Connection and an Interaction Directly
-
-`CciTemplate` also lets you work directly with CCI connections and
-interactions, in the same manner as `JdbcTemplate` and `JmsTemplate`. This is useful
-when you want to perform multiple operations on a CCI connection or interaction, for
-example.
-
-The `ConnectionCallback` interface provides a CCI `Connection` as an argument (to
-perform custom operations on it) plus the CCI `ConnectionFactory` with which the `Connection`
-was created. The latter can be useful (for example, to get an associated
-`RecordFactory` instance and create indexed/mapped records).
-The following listing shows the `ConnectionCallback` interface definition:
-
-[source,java,indent=0]
-[subs="verbatim,quotes"]
-----
-	public interface ConnectionCallback {
-
-		Object doInConnection(Connection connection, ConnectionFactory connectionFactory)
-				throws ResourceException, SQLException, DataAccessException;
-
-	}
-----
-
-The `InteractionCallback` interface provides the CCI `Interaction` (to perform
-custom operations on it) plus the corresponding CCI `ConnectionFactory`.
-The following listing shows the `InteractionCallback` interface definition:
-
-[source,java,indent=0]
-[subs="verbatim,quotes"]
-----
-	public interface InteractionCallback {
-
-		Object doInInteraction(Interaction interaction, ConnectionFactory connectionFactory)
-			throws ResourceException, SQLException, DataAccessException;
-
-	}
-----
-
-NOTE: `InteractionSpec` objects can either be shared across multiple template calls or be newly
-created inside every callback method. This is completely up to the DAO implementation.
-
-
-[[cci-template-example]]
-==== Example of `CciTemplate` Usage
-
-In this section, we show the usage of the `CciTemplate` to access a CICS with
-ECI mode, with the IBM CICS ECI connector.
-
-First, we must do some initializations on the CCI `InteractionSpec` to specify which
-CICS program to access and how to interact with it, as the following example shows:
-
-[source,java,indent=0]
-[subs="verbatim,quotes"]
-----
-	ECIInteractionSpec interactionSpec = new ECIInteractionSpec();
-	interactionSpec.setFunctionName("MYPROG");
-	interactionSpec.setInteractionVerb(ECIInteractionSpec.SYNC_SEND_RECEIVE);
-----
-
-Then the program can use CCI through Spring's template and specify mappings between custom
-objects and CCI `Records`, as the following example shows:
-
-[source,java,indent=0]
-[subs="verbatim,quotes"]
-----
-	public class MyDaoImpl extends CciDaoSupport implements MyDao {
-
-		public OutputObject getData(InputObject input) {
-			ECIInteractionSpec interactionSpec = ...;
-
-		OutputObject output = (ObjectOutput) getCciTemplate().execute(interactionSpec,
-			new RecordCreator() {
-				public Record createRecord(RecordFactory recordFactory) throws ResourceException {
-					return new CommAreaRecord(input.toString().getBytes());
-				}
-			},
-			new RecordExtractor() {
-				public Object extractData(Record record) throws ResourceException {
-					CommAreaRecord commAreaRecord = (CommAreaRecord)record;
-					String str = new String(commAreaRecord.toByteArray());
-					String field1 = string.substring(0,6);
-					String field2 = string.substring(6,1);
-					return new OutputObject(Long.parseLong(field1), field2);
-				}
-			});
-
-			return output;
-		}
-	}
-----
-
-As discussed previously, you can use callbacks to work directly on CCI connections or
-interactions. The following example shows how to do so:
-
-[source,java,indent=0]
-[subs="verbatim,quotes"]
-----
-	public class MyDaoImpl extends CciDaoSupport implements MyDao {
-
-		public OutputObject getData(InputObject input) {
-			ObjectOutput output = (ObjectOutput) getCciTemplate().execute(
-				new ConnectionCallback() {
-					public Object doInConnection(Connection connection,
-							ConnectionFactory factory) throws ResourceException {
-
-						// do something...
-
-					}
-				});
-			}
-			return output;
-		}
-
-	}
-----
-
-NOTE: With a `ConnectionCallback`, the `Connection` used is managed and closed by the
-`CciTemplate`, but the callback implementation must manage any interactions created on the
-connection.
-
-For a more specific callback, you can implement an `InteractionCallback`. If you do so, the passed-in
-`Interaction` is managed and closed by the `CciTemplate`. The following example shows how to do so:
-
-[source,java,indent=0]
-[subs="verbatim,quotes"]
-----
-	public class MyDaoImpl extends CciDaoSupport implements MyDao {
-
-		public String getData(String input) {
-			ECIInteractionSpec interactionSpec = ...;
-			String output = (String) getCciTemplate().execute(interactionSpec,
-				new InteractionCallback() {
-					public Object doInInteraction(Interaction interaction,
-							ConnectionFactory factory) throws ResourceException {
-						Record input = new CommAreaRecord(inputString.getBytes());
-						Record output = new CommAreaRecord();
-						interaction.execute(holder.getInteractionSpec(), input, output);
-						return new String(output.toByteArray());
-					}
-				});
-			return output;
-		}
-
-	}
-----
-
-For the preceding examples, the corresponding configuration of the involved Spring beans
-could resemble the following example in non-managed mode:
-
-[source,xml,indent=0]
-[subs="verbatim,quotes"]
-----
-	<bean id="managedConnectionFactory" class="com.ibm.connector2.cics.ECIManagedConnectionFactory">
-		<property name="serverName" value="TXSERIES"/>
-		<property name="connectionURL" value="local:"/>
-		<property name="userName" value="CICSUSER"/>
-		<property name="password" value="CICS"/>
-	</bean>
-
-	<bean id="connectionFactory" class="org.springframework.jca.support.LocalConnectionFactoryBean">
-		<property name="managedConnectionFactory" ref="managedConnectionFactory"/>
-	</bean>
-
-	<bean id="component" class="mypackage.MyDaoImpl">
-		<property name="connectionFactory" ref="connectionFactory"/>
-	</bean>
-----
-
-In managed mode (that is, in a Java EE environment), the configuration could resemble
-the following example:
-
-[source,xml,indent=0]
-[subs="verbatim,quotes"]
-----
-	<jee:jndi-lookup id="connectionFactory" jndi-name="eis/cicseci"/>
-
-	<bean id="component" class="MyDaoImpl">
-		<property name="connectionFactory" ref="connectionFactory"/>
-	</bean>

-[[cci-object]]
-=== Modeling CCI Access as Operation Objects
-
-The `org.springframework.jca.cci.object` package contains support classes that let you
-access the EIS in a different style: through reusable operation objects, analogous to
-Spring's JDBC operation objects (see the <<data-access.adoc#jdbc, JDBC section of the
-Data Access chapter>>). This usually encapsulates the CCI API. An application-level
-input object is passed to the operation object, so it can construct the input record and
-then convert the received record data to an application-level output object and return it.
-
-NOTE: This approach is internally based on the `CciTemplate` class and the `RecordCreator`
-or `RecordExtractor` interfaces, reusing the machinery of Spring's core CCI support.
-
-
-[[cci-object-mapping-record]]
-==== Using `MappingRecordOperation`
-
-`MappingRecordOperation` essentially performs the same work as `CciTemplate` but
-represents a specific, pre-configured operation as an object. It provides two template
-methods to specify how to convert an input object to an input record and how to convert

-
-* `createInputRecord(..)`: to specify how to convert an input object to an input `Record`
-* `extractOutputData(..)`: to specify how to extract an output object from an output `Record`
-

-----
-
-Thereafter, ito execute an EIS operation, you need to use a single `execute`
-method, passing in an application-level input object and receiving an application-level
-output object as the result. The following example shows how to do so:

-	}
-----
-
-Contrary to the `CciTemplate` class, this `execute(..)` method does not
-have an `InteractionSpec` as an argument. Instead, the `InteractionSpec` is global to the
-operation. You must use the following constructor to instantiate an operation object
-with a specific `InteractionSpec`. The following example shows how to do so:
-
-[source,java,indent=0]

-[[cci-object-mapping-comm-area]]
-==== Using `MappingCommAreaOperation`
-
-Some connectors use records based on a COMMAREA, which represents an array of bytes
-that contain parameters to send to the EIS and the data returned by it. Spring provides a
-special operation class for working directly on COMMAREA rather than on records. The
-`MappingCommAreaOperation` class extends the `MappingRecordOperation` class to provide
-this special COMMAREA support. It implicitly uses the `CommAreaRecord` class as the input
-and output record type and provides two new methods to convert an input object into an
-input COMMAREA and convert the output COMMAREA into an output object. The following
-listing shows the relevant method signatures:
-
-[source,java,indent=0]
-[subs="verbatim,quotes"]
-----
-	public abstract class MappingCommAreaOperation extends MappingRecordOperation {
-
-		...
-
-		protected abstract byte[] objectToBytes(Object inObject)
-				throws IOException, DataAccessException;
-
-		protected abstract Object bytesToObject(byte[] bytes)
-			throws IOException, DataAccessException;
-
-		...

-==== Automatic Output Record Generation
-
-As every `MappingRecordOperation` subclass is based on CciTemplate internally, the same
-way to automatically generate output records as with `CciTemplate` is available.
-Every operation object provides a corresponding `setOutputRecordCreator(..)` method.
-For further information, see <<automatic-output-generation>>.

-==== Example of `MappingRecordOperation` Usage
-
-In this section, we show how to use `MappingRecordOperation` to access a
-database with the Blackbox CCI connector.
-
-NOTE: The original version of this connector is provided by the Java EE SDK (version 1.3),
-which is available from Oracle.
-
-First, you must do some initializations on the CCI `InteractionSpec` to specify which
-SQL request to execute. In the following example, we directly define the way to convert the
-parameters of the request to a CCI record and the way to convert the CCI result record
-to an instance of the `Person` class:
-
-[source,java,indent=0]
-[subs="verbatim,quotes"]
-----
-	public class PersonMappingOperation extends MappingRecordOperation {
-
-		public PersonMappingOperation(ConnectionFactory connectionFactory) {
-			setConnectionFactory(connectionFactory);
-			CciInteractionSpec interactionSpec = new CciConnectionSpec();
-			interactionSpec.setSql("select * from person where person_id=?");
-			setInteractionSpec(interactionSpec);
-		}
-
-		protected Record createInputRecord(RecordFactory recordFactory,
-				Object inputObject) throws ResourceException {
-			Integer id = (Integer) inputObject;
-			IndexedRecord input = recordFactory.createIndexedRecord("input");
-			input.add(new Integer(id));
-			return input;
-		}
-
-		protected Object extractOutputData(Record outputRecord)
-				throws ResourceException, SQLException {
-			ResultSet rs = (ResultSet) outputRecord;
-			Person person = null;
-			if (rs.next()) {
-				Person person = new Person();
-				person.setId(rs.getInt("person_id"));
-				person.setLastName(rs.getString("person_last_name"));
-				person.setFirstName(rs.getString("person_first_name"));
-			}
-			return person;
-		}
-	}
-----
-
-Then the application can execute the operation object, with the person identifier as an
-argument. Note that you could set up the operation object as a shared instance, as it is
-thread-safe. The following executes the operation object with the person identifier as an
-argument:
-
-[source,java,indent=0]
-[subs="verbatim,quotes"]
-----
-	public class MyDaoImpl extends CciDaoSupport implements MyDao {
-
-		public Person getPerson(int id) {
-			PersonMappingOperation query = new PersonMappingOperation(getConnectionFactory());
-			Person person = (Person) query.execute(new Integer(id));
-			return person;
-		}
-	}
-----

-
-[source,xml,indent=0]

-==== Example of `MappingCommAreaOperation` Usage
-
-In this section, we show how to use the usage of the `MappingCommAreaOperation` to access a
-CICS with ECI mode with the IBM CICS ECI connector.
-
-First, we need to initialize the CCI `InteractionSpec` to specify which CICS program
-to access and how to interact with it, as the following example shows:
-
-[source,java,indent=0]
-[subs="verbatim,quotes"]
-----
-	public abstract class EciMappingOperation extends MappingCommAreaOperation {
-
-		public EciMappingOperation(ConnectionFactory connectionFactory, String programName) {
-			setConnectionFactory(connectionFactory);
-			ECIInteractionSpec interactionSpec = new ECIInteractionSpec(),
-			interactionSpec.setFunctionName(programName);
-			interactionSpec.setInteractionVerb(ECIInteractionSpec.SYNC_SEND_RECEIVE);
-			interactionSpec.setCommareaLength(30);
-			setInteractionSpec(interactionSpec);
-			setOutputRecordCreator(new EciOutputRecordCreator());
-		}
-
-		private static class EciOutputRecordCreator implements RecordCreator {
-			public Record createRecord(RecordFactory recordFactory) throws ResourceException {
-				return new CommAreaRecord();
-			}
-		}
-
-	}
-----
-
-We can then subclass the abstract `EciMappingOperation` class to specify mappings
-between custom objects and `Records`, as the following example shows:
-
-[source,java,indent=0]
-[subs="verbatim,quotes"]
-----
-	public class MyDaoImpl extends CciDaoSupport implements MyDao {
-
-		public OutputObject getData(Integer id) {
-			EciMappingOperation query = new EciMappingOperation(getConnectionFactory(), "MYPROG") {
-
-				protected abstract byte[] objectToBytes(Object inObject) throws IOException {
-					Integer id = (Integer) inObject;
-					return String.valueOf(id);
-				}
-
-				protected abstract Object bytesToObject(byte[] bytes) throws IOException;
-					String str = new String(bytes);
-					String field1 = str.substring(0,6);
-					String field2 = str.substring(6,1);
-					String field3 = str.substring(7,1);
-					return new OutputObject(field1, field2, field3);
-				}
-			});
-
-			return (OutputObject) query.execute(new Integer(id));

-[[cci-tx]]
-=== Transactions
-
-JCA specifies several levels of transaction support for resource adapters. The kind of
-transactions that your resource adapter supports is specified in its `ra.xml` file.
-There are essentially three options: none (for example, with the CICS EPI connector), local
-transactions (for example, with a CICS ECI connector), and global transactions (for example,
-with an IMS connector). The following example configures the global option:
-
-[source,xml,indent=0]
-[subs="verbatim,quotes"]
-----
-	<connector>
-		<resourceadapter>
-			<!-- <transaction-support>NoTransaction</transaction-support> -->
-			<!-- <transaction-support>LocalTransaction</transaction-support> -->
-			<transaction-support>XATransaction</transaction-support>
-		<resourceadapter>
-	<connector>
-----
-
-For global transactions, you can use Spring's generic transaction infrastructure to
-demarcate transactions, with `JtaTransactionManager` as the backend (delegating to the Java
-EE server's distributed transaction coordinator underneath).
-
-For local transactions on a single CCI `ConnectionFactory`, Spring provides a specific
-transaction-management strategy for CCI, analogous to the `DataSourceTransactionManager`
-for JDBC. The CCI API defines a local transaction object and corresponding local
-transaction demarcation methods. Spring's `CciLocalTransactionManager` executes such
-local CCI transactions in a fashion that is fully compliant with Spring's generic
-`PlatformTransactionManager` abstraction. The following example configures a `CciLocalTransactionManager`:
-
-[source,xml,indent=0]
-[subs="verbatim,quotes"]
-----
-	<jee:jndi-lookup id="eciConnectionFactory" jndi-name="eis/cicseci"/>
-
-	<bean id="eciTransactionManager"
-			class="org.springframework.jca.cci.connection.CciLocalTransactionManager">
-		<property name="connectionFactory" ref="eciConnectionFactory"/>
-	</bean>
-----
-
-You can use both transaction strategies with any of Spring's transaction demarcation
-facilities, be it declarative or programmatic. This is a consequence of Spring's generic
-`PlatformTransactionManager` abstraction, which decouples transaction demarcation from
-the actual execution strategy. You can switch between `JtaTransactionManager` and
-`CciLocalTransactionManager` as needed, keeping your transaction demarcation as-is.
-
-For more information on Spring's transaction facilities, see
-<<data-access.adoc#transaction, Transaction Management>>.

Subject: [PATCH 1055/2315] Disable and remove unsupported features from native
 images

This commit removes load time weaving, CGLIB and Objenesis support
from native images.

GraalDetector has been removed for now because of
https://github.com/oracle/graal/issues/2594. It should be reintroduced
when this bug will be fixed with NativeImageDetector class name.

Closes gh-25179

Subject: [PATCH 1061/2315] Adjust WebFlux behavior for @RequestPart List<T>

List<T> support was added relatively late, incorrectly decoding each
part to T which means no way to decode a single part to List<T> and
thatis the most common case (vs multipart parts with the same name).
This behavior was further misaligned with Spring MVC as well as with
the behavior for T[].

Closes gh-22973

Subject: [PATCH 1065/2315] Use MonoProcessor instead of FluxIdentityProcessor

We just need to signal completion when close() is called. MonoProcessor
should suffice and we can avoid a hard dependency on Reactor 3.4.

Subject: [PATCH 1066/2315] Map from charset name rather than Charset

With this commit it is no longer assumed that all charset names in the
JsonEncoding can be resolved by Charset.forName. Instead, we store the
charset name itself, rather than the Charset object.

Subject: [PATCH 1071/2315] Fix missing contextPath when mutating
 ServerHttpRequest

This commit ensures that when mutating `ServerHttpRequest` instances,
the original contextPath information is copied to the request being
built.

Note that mutation on the `contextPath(String)` or `path(String)` should
be reflected to the other. (See their Javadoc for more information).

Fixes gh-25279

Subject: [PATCH 1072/2315] Reduce String creation in BeanPropertyRowMapper

Prior to this commit the BeanPropertyRowMapper used
String.substring and String.toLowerCase to parse the
field names. This would generate more String than needed.

Instead one could iterate over the internal char[] of the
String and use the Character methods instead. This reduces
the String creation.

Closes gh-25301

Subject: [PATCH 1087/2315] Refine solution for 21de09

The following was reported after the change and is related to it:
https://github.com/reactor/reactor-netty/issues/1170. An HTTP HEAD with the body
not consumed. Connection is disposed and closed leading to subsequent request to
fail. Adding toBodilessEntity() helps.

This change does not close the connection but rather drains the body which does
not impact subsequent re-use of the connection. This however may compete with a
late subscriber actually attempting to read the response. At that point there is
little choice but to raise an ISE with a more specific description.

See gh-25216

Subject: [PATCH 1092/2315] Direct matches by URL path work again

This commit fixes a recent regression as a result of 5225a5741197a7e2123437709c2468e4537b0469
with the determination of non-pattern vs pattern URLs. That in turn affects the ability to perform
direct matches by URL path.

There is also a fix in PathPattern to recognize "catch-all" patterns as pattern syntax.

See gh-24945

Subject: [PATCH 1093/2315] (Re)introduce DefaultMultipartMessageReader

This commit introduces the DefaultMultipartMessageReader, a fully
reactive multipart parser without third party dependencies.

An earlier version of this code was introduced in fb642ce, but removed
again in 77c24aa because of buffering issues.

Closes gh-21659

Subject: [PATCH 1094/2315] Remove UndertowDataBuffer

This commit removes the UndertowDataBuffer, in favor of using regular
DataBuffers from the DataBufferFactory. During the development of the
DefaultPartHttpMessageReader, it was determined that invoking various
slicing and releasing operators on the UndertowDataBuffer resulted in
memory leaks. This commit fixes that.

Subject: [PATCH 1098/2315] Use @SafeVarargs in Jackson builder and factory

Using @SafeVarargs in Jackson mapper builder and factory bean classes
allows the varargs methods to be used without a compiler warning. The
implementations of these methods do not perform unsafe operations on
their varargs parameter. It is therefore safe to add this annotation.

The following two methods are changed:

- add @SafeVarargs to Jackson2ObjectMapperBuilder#modulesToInstall
  and make it final
- add @SafeVarargs to
  Jackson2ObjectMapperFactoryBean#setModulesToInstall and make it final

This is a backwards incompatible change as these methods now have to be
declared final. Existing subclasses that override one of these methods
will break.

Closes gh-25311

From 9876ca003b996f51fcf567391fb135b58c936667 Mon Sep 17 00:00:00 2001
From: Sam Brannen <sbrannen@vmware.com>

Subject: [PATCH 1104/2315] Support fragments in
 UriComponentsBuilder.fromHttpUrl()

Prior to this commit, UriComponentsBuilder.fromHttpUrl() threw an
IllegalArgumentException if the provided URL contained a fragment.

This commit aligns the implementation of fromHttpUrl() with that of
fromUriString(), by parsing a fragment and storing it in the builder.

Closes gh-25300

Subject: [PATCH 1109/2315] Check for valid IPv6 host in
 UriComponentsBuilder.fromUriString

PR gh-358 introduced a "scheme but no host" check in the fromHttpUrl()
method in UriComponentsBuilder, but a similar check was not added to
fromUriString() at that time.

This commit introduces a "scheme but no host" check in fromUriString()
to align with the functionality in fromHttpUrl().

Note, however that the regular expressions used to match against the
hostname or IP address are inexact and still permit invalid host names
or IP addresses. True validation of the host portion of the URI is out
of scope for this commit.

Closes gh-25334

Subject: [PATCH 1113/2315] RouterFunction honors PathPatternParser in config

This commit introduces a way to change the PathPatternParser used in
PathPredicates, by way of a ChangePathPatternParserVisitor. This
visitor is used by both WebFluxConfigurationSupport and
WebMvcConfigurationSupport to make sure the configured parser is used.

Closes gh-23236

Subject: [PATCH 1122/2315] Use System.nanoTime() for Random seed in
 SocketUtils

Prior to this commit, SocketUtils used System.currentTimeMillis() for
the seed for the java.util.Random instance used internally. The use of
the milliseconds value returned by currentTimeMillis() can lead to
collisions for randomly selected free ports for tests executing in
parallel on the same computer.

This commit therefore switches to System.nanoTime() for the Random seed
used in SocketUtils in an attempt to avoid such collisions for tests
executing in parallel in different JVMs on the same computer.

Subject: [PATCH 1125/2315] PathPattern caching with HandlerMappingIntrospector

This commit evolves the solution from M1 by parsing and caching patterns with the
target HandlerMapping's PathPatternParser. This makes it unnecessary for callers to
be aware of pattern parsing.

Closes gh-25312

Subject: [PATCH 1130/2315] Make Profiles created via Profiles.of() comparable

Prior to this commit, a Profiles instance created via Profiles.of() was
not considered equivalent to another Profiles instance created via
Profiles.of() with the exact same expressions. This makes it difficult
to mock invocations of Environment#acceptsProfiles(Profiles) -- for
example, when using a mocking library such as Mockito.

This commit makes Profiles instances created via Profiles.of()
"comparable" by implementing equals() and hashCode() in ParsedProfiles.

Note, however, that equivalence is only guaranteed if the exact same
profile expression strings are supplied to Profiles.of(). In other
words, Profiles.of("A & B", "C | D") is equivalent to
Profiles.of("A & B", "C | D") and Profiles.of("C | D", "A & B"), but
Profiles.of("X & Y") is not equivalent to Profiles.of("X&Y") or
Profiles.of("Y & X").

Closes gh-25340

Subject: [PATCH 1143/2315] Deprecate remoting technologies support

Because of security and broader industry support, support for several
remoting technologies is now deprecated and scheduled for removal in
Spring Framework 6.0.

This commit deprecates the following remoting technologies:

* HTTPInvoker
* RMI
* Hessian
* JMS remoting

Other remoting technologies like EJB or JAXWS might be deprecated in the
future depending on industry support.

Closes gh-25379

 This part of the reference documentation covers the Spring Framework's integration with
-a number of Java EE (and related) technologies.
-
+a number technologies.
 
 
+[[rest-client-access]]
+== REST Endpoints
 
-[[remoting]]
-== Remoting and Web Services
+The Spring Framework provides two choices for making calls to REST endpoints:
 
-Spring provides support for remoting with various technologies.
-The remoting support eases the development of remote-enabled services, implemented
-via Java interfaces and objects as input and output. Currently, Spring supports the
-following remoting technologies:
+* <<rest-resttemplate>>: The original Spring REST client with a synchronous, template
+method API.
+* <<web-reactive.adoc#webflux-client, WebClient>>: a non-blocking, reactive alternative
+that supports both synchronous and asynchronous as well as streaming scenarios.
 
-* <<remoting-rmi,Remote Method Invocation (RMI)>>: Through the use of  `RmiProxyFactoryBean` and
-  `RmiServiceExporter`, Spring supports both traditional RMI (with `java.rmi.Remote`
-  interfaces and `java.rmi.RemoteException`) and transparent remoting through RMI
-  invokers (with any Java interface).
-* <<remoting-httpinvoker>>: Spring provides a special remoting strategy that allows
-  for Java serialization though HTTP, supporting any Java interface (as the RMI
-  invoker does). The corresponding support classes are `HttpInvokerProxyFactoryBean`
-  and `HttpInvokerServiceExporter`.
-* <<remoting-caucho-protocols-hessian>>: By using Spring's `HessianProxyFactoryBean` and the
-  `HessianServiceExporter`, you can transparently expose your services through the
-  lightweight binary HTTP-based protocol provided by Caucho.
-* <<remoting-web-services>>: Spring provides remoting support for web services through JAX-WS.
-* <<remoting-jms>>: Remoting via JMS as the underlying protocol is supported through the
-  `JmsInvokerServiceExporter` and `JmsInvokerProxyFactoryBean` classes in the
-   `spring-jms` module.
-* <<remoting-amqp>>: Remoting via AMQP as the underlying protocol is supported by the
-  separate Spring AMQP project.
+NOTE: As of 5.0 the `RestTemplate` is in maintenance mode, with only minor requests for
+changes and bugs to be accepted going forward. Please, consider using the
+<<web-reactive.adoc#webflux-client, WebClient>> which offers a more modern API and
+supports sync, async, and streaming scenarios.
 
-While discussing the remoting capabilities of Spring, we use the following domain
-model and corresponding services:

+[[rest-resttemplate]]
+=== `RestTemplate`
 
-		private String name;
+The `RestTemplate` provides a higher level API over HTTP client libraries. It makes it
+easy to invoke REST endpoints in a single line. It exposes the following groups of
+overloaded methods:
 
-		public String getName(){
-			return name;
-		}

-			// do something...

+| `postForEntity`

-This section starts by exposing the service to a remote client by using RMI and talk a bit
-about the drawbacks of using RMI. It then continues with an example that uses Hessian as
-the protocol.
+| `patchForObject`
+| Updates a resource by using PATCH and returns the representation from the response.
+Note that the JDK `HttpURLConnection` does not support the `PATCH`, but Apache
+HttpComponents and others do.
 
+| `delete`
+| Deletes the resources at the specified URI by using DELETE.
 
+| `optionsForAllow`
+| Retrieves allowed HTTP methods for a resource by using ALLOW.
 
-[[remoting-rmi]]
-=== RMI
+| `exchange`
+| More generalized (and less opinionated) version of the preceding methods that provides extra
+flexibility when needed. It accepts a `RequestEntity` (including HTTP method, URL, headers,
+and body as input) and returns a `ResponseEntity`.
 
-By using Spring's support for RMI, you can transparently expose your services through the
-RMI infrastructure. After having this set up, you basically have a configuration similar
-to remote EJBs, except for the fact that there is no standard support for security
-context propagation or remote transaction propagation. Spring does provide hooks for
-such additional invocation context when you use the RMI invoker, so you can, for example,
-plug in security frameworks or custom security credentials.
+These methods allow the use of `ParameterizedTypeReference` instead of `Class` to specify
+a response type with generics.
 
+| `execute`
+| The most generalized way to perform a request, with full control over request
+preparation and response extraction through callback interfaces.
 
-[[remoting-rmi-server]]
-==== Exporting the Service by Using `RmiServiceExporter`
+|===
 
-Using the `RmiServiceExporter`, we can expose the interface of our AccountService object
-as RMI object. The interface can be accessed by using `RmiProxyFactoryBean`, or via
-plain RMI in case of a traditional RMI service. The `RmiServiceExporter` explicitly
-supports the exposing of any non-RMI services via RMI invokers.
+[[rest-resttemplate-create]]
+==== Initialization
 
-We first have to set up our service in the Spring container.
-The following example shows how to do so:
+The default constructor uses `java.net.HttpURLConnection` to perform requests. You can
+switch to a different HTTP library with an implementation of `ClientHttpRequestFactory`.
+There is built-in support for the following:
 
-[source,xml,indent=0]
-[subs="verbatim,quotes"]
-----
-	<bean id="accountService" class="example.AccountServiceImpl">
-		<!-- any additional properties, maybe a DAO? -->
-	</bean>
-----
+* Apache HttpComponents
+* Netty
+* OkHttp
 
-Next, we have to expose our service by using `RmiServiceExporter`.
-The following example shows how to do so:
+For example, to switch to Apache HttpComponents, you can use the following:
 
-[source,xml,indent=0]
+[source,java,indent=0]
 [subs="verbatim,quotes"]
 ----
-	<bean class="org.springframework.remoting.rmi.RmiServiceExporter">
-		<!-- does not necessarily have to be the same name as the bean to be exported -->
-		<property name="serviceName" value="AccountService"/>
-		<property name="service" ref="accountService"/>
-		<property name="serviceInterface" value="example.AccountService"/>
-		<!-- defaults to 1099 -->
-		<property name="registryPort" value="1199"/>
-	</bean>
+	RestTemplate template = new RestTemplate(new HttpComponentsClientHttpRequestFactory());
 ----
 
-In the preceding example, we override the port for the RMI registry. Often, your application
-server also maintains an RMI registry, and it is wise to not interfere with that one.
-Furthermore, the service name is used to bind the service. So, in the preceding example, the
-service is bound at `'rmi://HOST:1199/AccountService'`. We use this URL later on to link in
-the service at the client side.
+Each `ClientHttpRequestFactory` exposes configuration options specific to the underlying
+HTTP client library -- for example, for credentials, connection pooling, and other details.
 
-NOTE: The `servicePort` property has been omitted (it defaults to 0). This means that an
-anonymous port is used to communicate with the service.
+TIP: Note that the `java.net` implementation for HTTP requests can raise an exception when
+accessing the status of a response that represents an error (such as 401). If this is an
+issue, switch to another HTTP client library.
 
+[[rest-resttemplate-uri]]
+===== URIs
 
-[[remoting-rmi-client]]
-==== Linking in the Service at the Client
+Many of the `RestTemplate` methods accept a URI template and URI template variables,
+either as a `String` variable argument, or as `Map<String,String>`.
 
-Our client is a simple object that uses the `AccountService` to manage accounts,
-as the following example shows:
+The following example uses a `String` variable argument:
 
 [source,java,indent=0]
 [subs="verbatim,quotes"]
 ----
-	public class SimpleObject {
+	String result = restTemplate.getForObject(
+			"https://example.com/hotels/{hotel}/bookings/{booking}", String.class, "42", "21");
+----
 
-		private AccountService accountService;
+The following example uses a `Map<String, String>`:
 
-		public void setAccountService(AccountService accountService) {
-			this.accountService = accountService;
-		}
+[source,java,indent=0]
+[subs="verbatim,quotes"]
+----
+	Map<String, String> vars = Collections.singletonMap("hotel", "42");
 
-		// additional methods using the accountService
-	}
+	String result = restTemplate.getForObject(
+			"https://example.com/hotels/{hotel}/rooms/{hotel}", String.class, vars);
 ----
 
-To link in the service on the client, we create a separate Spring container,
-to contain the following simple object and the service linking configuration bits:
+Keep in mind URI templates are automatically encoded, as the following example shows:
 
-[source,xml,indent=0]
+[source,java,indent=0]
 [subs="verbatim,quotes"]
 ----
-	<bean class="example.SimpleObject">
-		<property name="accountService" ref="accountService"/>
-	</bean>
+	restTemplate.getForObject("https://example.com/hotel list", String.class);
 
-	<bean id="accountService" class="org.springframework.remoting.rmi.RmiProxyFactoryBean">
-		<property name="serviceUrl" value="rmi://HOST:1199/AccountService"/>
-		<property name="serviceInterface" value="example.AccountService"/>
-	</bean>
+	// Results in request to "https://example.com/hotel%20list"
 ----
 
-That is all we need to do to support the remote account service on the client. Spring
-transparently creates an invoker and remotely enables the account service through the
-`RmiServiceExporter`. At the client, we link it in by using the `RmiProxyFactoryBean`.
-
+You can use the `uriTemplateHandler` property of `RestTemplate` to customize how URIs
+are encoded. Alternatively, you can prepare a `java.net.URI` and pass it into one of
+the `RestTemplate` methods that accepts a `URI`.
 
+For more details on working with and encoding URIs, see <<web.adoc#mvc-uri-building, URI Links>>.
 
-[[remoting-caucho-protocols]]
-=== Using Hessian to Remotely Call Services through HTTP
+[[rest-template-headers]]
+===== Headers
 
-Hessian offers a binary HTTP-based remoting protocol. It is developed by Caucho,
-and you can find more information about Hessian itself at https://www.caucho.com/[].
+You can use the `exchange()` methods to specify request headers, as the following example shows:
 
+[source,java,indent=0]
+[subs="verbatim,quotes"]

-Hessian communicates through HTTP and does so by using a custom servlet. By using Spring's
-`DispatcherServlet` principles (see <<webmvc.adoc#mvc-servlet>>), we can wire up such a
-servlet to expose your services. First, we have to create a new servlet in our application,
-as shown in the following excerpt from `web.xml`:
+	ResponseEntity<String> response = template.exchange(requestEntity, String.class);
 
-[source,xml,indent=0]
-[subs="verbatim,quotes"]
+	String responseHeader = response.getHeaders().getFirst("MyResponseHeader");

-If you are familiar with Spring's `DispatcherServlet` principles, you probably
-know that now you have to create a Spring container configuration resource named
-`remoting-servlet.xml` (after the name of your servlet) in the `WEB-INF` directory.
-The application context is used in the next section.
-
-Alternatively, consider the use of Spring's simpler `HttpRequestHandlerServlet`. Doing so
-lets you embed the remote exporter definitions in your root application context (by
-default, in `WEB-INF/applicationContext.xml`), with individual servlet definitions
-pointing to specific exporter beans. In this case, each servlet name needs to match the bean name of
-its target exporter.
+You can obtain response headers through many `RestTemplate` method variants that return
+`ResponseEntity`.
 
+[[rest-template-body]]
+==== Body
 
-[[remoting-caucho-protocols-hessian-server]]
-==== Exposing Your Beans by Using `HessianServiceExporter`
+Objects passed into and returned from `RestTemplate` methods are converted to and from raw
+content with the help of an `HttpMessageConverter`.
 
-In the newly created application context called `remoting-servlet.xml`, we create a
-`HessianServiceExporter` to export our services, as the following example shows:
+On a POST, an input object is serialized to the request body, as the following example shows:
 
-[source,xml,indent=0]
-[subs="verbatim,quotes"]
 ----
-	<bean id="accountService" class="example.AccountServiceImpl">
-		<!-- any additional properties, maybe a DAO? -->
-	</bean>
-
-	<bean name="/AccountService" class="org.springframework.remoting.caucho.HessianServiceExporter">
-		<property name="service" ref="accountService"/>
-		<property name="serviceInterface" value="example.AccountService"/>
-	</bean>
+URI location = template.postForLocation("https://example.com/people", person);
 ----
 
-Now we are ready to link in the service at the client. No explicit handler mapping is
-specified (to map request URLs onto services), so we use `BeanNameUrlHandlerMapping`
-used. Hence, the service is exported at the URL indicated through its bean name
-within the containing `DispatcherServlet` instance's mapping (as defined earlier):
-`https://HOST:8080/remoting/AccountService`.
+You need not explicitly set the Content-Type header of the request. In most cases,
+you can find a compatible message converter based on the source `Object` type, and the chosen
+message converter sets the content type accordingly. If necessary, you can use the
+`exchange` methods to explicitly provide the `Content-Type` request header, and that, in
+turn, influences what message converter is selected.
 
-Alternatively, you can create a `HessianServiceExporter` in your root application context (for example,
-in `WEB-INF/applicationContext.xml`), as the following example shows:
+On a GET, the body of the response is deserialized to an output `Object`, as the following example shows:
 
-[source,xml,indent=0]
-[subs="verbatim,quotes"]
 ----
-	<bean name="accountExporter" class="org.springframework.remoting.caucho.HessianServiceExporter">

-		<property name="serviceInterface" value="example.AccountService"/>
-	</bean>
+Person person = restTemplate.getForObject("https://example.com/people/{id}", Person.class, 42);
 ----
 
-In the latter case, you should define a corresponding servlet for this exporter in `web.xml`,
-with the same end result: The exporter gets mapped to the request path at
-`/remoting/AccountService`. Note that the servlet name needs to match the bean name of
-the target exporter. The following example shows how to do so:
+The `Accept` header of the request does not need to be explicitly set. In most cases,
+a compatible message converter can be found based on the expected response type, which
+then helps to populate the `Accept` header. If necessary, you can use the `exchange`
+methods to provide the `Accept` header explicitly.
 
-[source,xml,indent=0]
+By default, `RestTemplate` registers all built-in
+<<rest-message-conversion, message converters>>, depending on classpath checks that help
+to determine what optional conversion libraries are present. You can also set the message
+converters to use explicitly.
+
+[[rest-message-conversion]]
+==== Message Conversion
+[.small]#<<web-reactive.adoc#webflux-codecs, WebFlux>>#
+
+The `spring-web` module contains the `HttpMessageConverter` contract for reading and
+writing the body of HTTP requests and responses through `InputStream` and `OutputStream`.
+`HttpMessageConverter` instances are used on the client side (for example, in the `RestTemplate`) and
+on the server side (for example, in Spring MVC REST controllers).
+
+Concrete implementations for the main media (MIME) types are provided in the framework
+and are, by default, registered with the `RestTemplate` on the client side and with
+`RequestMethodHandlerAdapter` on the server side (see
+<<web.adoc#mvc-config-message-converters, Configuring Message Converters>>).
+
+The implementations of `HttpMessageConverter` are described in the following sections.
+For all converters, a default media type is used, but you can override it by setting the
+`supportedMediaTypes` bean property. The following table describes each implementation:
+
+[[rest-message-converters-tbl]]
+.HttpMessageConverter Implementations
+[cols="1,3"]
+|===
+| MessageConverter | Description
+
+| `StringHttpMessageConverter`
+| An `HttpMessageConverter` implementation that can read and write `String` instances from the HTTP
+request and response. By default, this converter supports all text media types
+(`text/{asterisk}`) and writes with a `Content-Type` of `text/plain`.
+
+| `FormHttpMessageConverter`
+| An `HttpMessageConverter` implementation that can read and write form data from the HTTP
+request and response. By default, this converter reads and writes the
+`application/x-www-form-urlencoded` media type. Form data is read from and written into a
+`MultiValueMap<String, String>`. The converter can also write (but not read) multipart
+data read from a `MultiValueMap<String, Object>`. By default, `multipart/form-data` is
+supported. As of Spring Framework 5.2, additional multipart subtypes can be supported for
+writing form data. Consult the javadoc for `FormHttpMessageConverter` for further details.
+
+| `ByteArrayHttpMessageConverter`
+| An `HttpMessageConverter` implementation that can read and write byte arrays from the
+HTTP request and response. By default, this converter supports all media types (`{asterisk}/{asterisk}`)
+and writes with a `Content-Type` of `application/octet-stream`. You can override this
+by setting the `supportedMediaTypes` property and overriding `getContentType(byte[])`.
+
+| `MarshallingHttpMessageConverter`
+| An `HttpMessageConverter` implementation that can read and write XML by using Spring's
+`Marshaller` and `Unmarshaller` abstractions from the `org.springframework.oxm` package.
+This converter requires a `Marshaller` and `Unmarshaller` before it can be used. You can inject these
+through constructor or bean properties. By default, this converter supports
+`text/xml` and `application/xml`.
+
+| `MappingJackson2HttpMessageConverter`
+| An `HttpMessageConverter` implementation that can read and write JSON by using Jackson's
+`ObjectMapper`. You can customize JSON mapping as needed through the use of Jackson's
+provided annotations. When you need further control (for cases where custom JSON
+serializers/deserializers need to be provided for specific types), you can inject a custom `ObjectMapper`
+through the `ObjectMapper` property. By default, this
+converter supports `application/json`.
+
+| `MappingJackson2XmlHttpMessageConverter`
+| An `HttpMessageConverter` implementation that can read and write XML by using
+https://github.com/FasterXML/jackson-dataformat-xml[Jackson XML] extension's
+`XmlMapper`. You can customize XML mapping as needed through the use of JAXB
+or Jackson's provided annotations. When you need further control (for cases where custom XML
+serializers/deserializers need to be provided for specific types), you can inject a custom `XmlMapper`
+through the `ObjectMapper` property. By default, this
+converter supports `application/xml`.
+
+| `SourceHttpMessageConverter`
+| An `HttpMessageConverter` implementation that can read and write
+`javax.xml.transform.Source` from the HTTP request and response. Only `DOMSource`,
+`SAXSource`, and `StreamSource` are supported. By default, this converter supports
+`text/xml` and `application/xml`.
+
+| `BufferedImageHttpMessageConverter`
+| An `HttpMessageConverter` implementation that can read and write
+`java.awt.image.BufferedImage` from the HTTP request and response. This converter reads
+and writes the media type supported by the Java I/O API.
+
+|===

+[[rest-template-jsonview]]

+
+You can specify a https://www.baeldung.com/jackson-json-view-annotation[Jackson JSON View]
+to serialize only a subset of the object properties, as the following example shows:

-[[remoting-caucho-protocols-hessian-client]]
-==== Linking in the Service on the Client
+[[rest-template-multipart]]
+===== Multipart
 
-By using the `HessianProxyFactoryBean`, we can link in the service at the client. The same
-principles apply as with the RMI example. We create a separate bean factory or
-application context and mention the following beans where the `SimpleObject` is by using
-the `AccountService` to manage accounts, as the following example shows:
+To send multipart data, you need to provide a `MultiValueMap<String, Object>` whose values
+may be an `Object` for part content, a `Resource` for a file part, or an `HttpEntity` for
+part content with headers. For example:
 
-[source,xml,indent=0]
+[source,java,intent=0]
 [subs="verbatim,quotes"]
 ----
-	<bean class="example.SimpleObject">
-		<property name="accountService" ref="accountService"/>
-	</bean>
+	MultiValueMap<String, Object> parts = new LinkedMultiValueMap<>();
 
-	<bean id="accountService" class="org.springframework.remoting.caucho.HessianProxyFactoryBean">
-		<property name="serviceUrl" value="https://remotehost:8080/remoting/AccountService"/>
-		<property name="serviceInterface" value="example.AccountService"/>
-	</bean>
-----
+	parts.add("fieldPart", "fieldValue");
+	parts.add("filePart", new FileSystemResource("...logo.png"));
+	parts.add("jsonPart", new Person("Jason"));
 
+	HttpHeaders headers = new HttpHeaders();
+	headers.setContentType(MediaType.APPLICATION_XML);
+	parts.add("xmlPart", new HttpEntity<>(myBean, headers));
+----
 
-[[remoting-caucho-protocols-security]]
-==== Applying HTTP Basic Authentication to a Service Exposed through Hessian
+In most cases, you do not have to specify the `Content-Type` for each part. The content
+type is determined automatically based on the `HttpMessageConverter` chosen to serialize
+it or, in the case of a `Resource` based on the file extension. If necessary, you can
+explicitly provide the `MediaType` with an `HttpEntity` wrapper.
 
-One of the advantages of Hessian is that we can easily apply HTTP basic authentication,
-because both protocols are HTTP-based. Your normal HTTP server security mechanism can
-be applied through using the `web.xml` security features, for example. Usually,
-you need not use per-user security credentials here. Rather, you can use shared credentials that you define
-at the `HessianProxyFactoryBean` level (similar to a JDBC `DataSource`), as the following example shows:
+Once the `MultiValueMap` is ready, you can pass it to the `RestTemplate`, as show below:
 
-[source,xml,indent=0]
+[source,java,intent=0]
 [subs="verbatim,quotes"]
 ----
-	<bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping">
-		<property name="interceptors" ref="authorizationInterceptor"/>
-	</bean>
-
-	<bean id="authorizationInterceptor"
-			class="org.springframework.web.servlet.handler.UserRoleAuthorizationInterceptor">
-		<property name="authorizedRoles" value="administrator,operator"/>
-	</bean>
+	MultiValueMap<String, Object> parts = ...;
+	template.postForObject("https://example.com/upload", parts, Void.class);
 ----
 
-In the preceding example, we explicitly mention the `BeanNameUrlHandlerMapping` and set
-an interceptor, to let only administrators and operators call the beans mentioned in
-this application context.
+If the `MultiValueMap` contains at least one non-`String` value, the `Content-Type` is set
+to `multipart/form-data` by the `FormHttpMessageConverter`. If the `MultiValueMap` has
+`String` values the `Content-Type` is defaulted to `application/x-www-form-urlencoded`.
+If necessary the `Content-Type` may also be set explicitly.
 
-NOTE: The preceding example does not show a flexible kind of security infrastructure. For
-more options as far as security is concerned, have a look at the Spring Security project
-at https://projects.spring.io/spring-security/.
 
+[[rest-async-resttemplate]]
+=== Using `AsyncRestTemplate` (Deprecated)
 
+The `AsyncRestTemplate` is deprecated. For all use cases where you might consider using
+`AsyncRestTemplate`, use the <<web-reactive.adoc#webflux-client, WebClient>> instead.
 
-[[remoting-httpinvoker]]
-=== Spring HTTP Invoker
 
-As opposed to Hessian, Spring HTTP invokers are both lightweight protocols that use their own slim
-serialization mechanisms and use the standard Java serialization
-mechanism to expose services through HTTP. This has a huge advantage if your arguments
-and return types are complex types that cannot be serialized by using the serialization
-mechanisms Hessian uses (see the next section for more considerations when
-you choose a remoting technology).
 
-Under the hood, Spring uses either the standard facilities provided by the JDK or
-Apache `HttpComponents` to perform HTTP calls. If you need more
-advanced and easier-to-use functionality, use the latter. See
-https://hc.apache.org/httpcomponents-client-ga/[hc.apache.org/httpcomponents-client-ga/]
-for more information.
+[[remoting]]
+== Remoting and Web Services
 
-[WARNING]
-====
-Be aware of vulnerabilities due to unsafe Java deserialization:
-Manipulated input streams can lead to unwanted code execution on the server
-during the deserialization step. As a consequence, do not expose HTTP invoker
-endpoints to untrusted clients. Rather, expose them only between your own services.
-In general, we strongly recommend using any other message format (such as JSON) instead.
+Spring provides support for remoting with various technologies.
+The remoting support eases the development of remote-enabled services, implemented
+via Java interfaces and objects as input and output. Currently, Spring supports the
+following remoting technologies:
 
-If you are concerned about security vulnerabilities due to Java serialization,
-consider the general-purpose serialization filter mechanism at the core JVM level,
-originally developed for JDK 9 but backported to JDK 8, 7 and 6 in the meantime. See
-https://blogs.oracle.com/java-platform-group/entry/incoming_filter_serialization_data_a
-and https://openjdk.java.net/jeps/290.

-[[remoting-httpinvoker-server]]
-==== Exposing the Service Object
+The following remoting technologies are now deprecated and will not be replaced:
 
-Setting up the HTTP invoker infrastructure for a service object closely resembles the
-way you would do the same by using Hessian. As Hessian support provides
-`HessianServiceExporter`, Spring's HttpInvoker support provides
-`org.springframework.remoting.httpinvoker.HttpInvokerServiceExporter`.
+* <<remoting-rmi,Remote Method Invocation (RMI)>>: Through the use of  `RmiProxyFactoryBean` and
+  `RmiServiceExporter`, Spring supports both traditional RMI (with `java.rmi.Remote`
+  interfaces and `java.rmi.RemoteException`) and transparent remoting through RMI
+  invokers (with any Java interface).
+* <<remoting-httpinvoker>>: Spring provides a special remoting strategy that allows
+  for Java serialization though HTTP, supporting any Java interface (as the RMI
+  invoker does). The corresponding support classes are `HttpInvokerProxyFactoryBean`
+  and `HttpInvokerServiceExporter`.
+* <<remoting-caucho-protocols-hessian>>: By using Spring's `HessianProxyFactoryBean` and the
+  `HessianServiceExporter`, you can transparently expose your services through the
+  lightweight binary HTTP-based protocol provided by Caucho.
+* <<remoting-jms>>: Remoting via JMS as the underlying protocol is supported through the
+  `JmsInvokerServiceExporter` and `JmsInvokerProxyFactoryBean` classes in the
+   `spring-jms` module.
+
+While discussing the remoting capabilities of Spring, we use the following domain
+model and corresponding services:
+
+[source,java,indent=0]
+[subs="verbatim,quotes"]

+	public class Account implements Serializable{
+
+		private String name;
+
+		public String getName(){
+			return name;
+		}
 
-To expose the `AccountService` (mentioned earlier) within a Spring Web MVC
-`DispatcherServlet`, the following configuration needs to be in place in the
-dispatcher's application context, as the following example shows:
+		public void setName(String name) {
+			this.name = name;
+		}
+	}

-Such an exporter definition is exposed through the `DispatcherServlet` instance's standard
-mapping facilities, as explained in <<remoting-caucho-protocols, the section on Hessian>>.
+		public void insertAccount(Account account);
 
-Alternatively, you can create an `HttpInvokerServiceExporter` in your root application context
-(for example, in `'WEB-INF/applicationContext.xml'`), as the following example shows:
+		public List<Account> getAccounts(String name);
+	}

-[[remoting-httpinvoker-client]]
-==== Linking in the Service at the Client
 
-Again, linking in the service from the client much resembles the way you would do it
-when you use Hessian. By using a proxy, Spring can translate your calls to
-HTTP POST requests to the URL that points to the exported service. The following example
-shows how to configure this arrangement:
 
-[source,xml,indent=0]
-[subs="verbatim,quotes"]
-----
-	<bean id="httpInvokerProxy" class="org.springframework.remoting.httpinvoker.HttpInvokerProxyFactoryBean">

-		<property name="serviceInterface" value="example.AccountService"/>
-	</bean>

+[[remoting-amqp]]
+=== AMQP
+Remoting via AMQP as the underlying protocol is supported in the Spring AMQP project.
+For further details please visit the {doc-spring-amqp}/html/#remoting[Spring Remoting]
+section of the Spring AMQP reference.
 
-As mentioned earlier, you can choose what HTTP client you want to use. By default, the
-`HttpInvokerProxy` uses the JDK's HTTP functionality, but you can also use the Apache
-`HttpComponents` client by setting the `httpInvokerRequestExecutor` property.
-The following example shows how to do so:
+[[remoting-autodection-remote-interfaces]]
+[NOTE]
+====
+Auto-detection is not implemented for remote interfaces
 
-[source,xml,indent=0]
-[subs="verbatim,quotes"]
-----
-	<property name="httpInvokerRequestExecutor">
-		<bean class="org.springframework.remoting.httpinvoker.HttpComponentsHttpInvokerRequestExecutor"/>
-	</property>
-----
+The main reason why auto-detection of implemented interfaces does not occur for remote
+interfaces is to avoid opening too many doors to remote callers. The target object might
+implement internal callback interfaces, such as `InitializingBean` or `DisposableBean`
+which one would not want to expose to callers.
+
+Offering a proxy with all interfaces implemented by the target usually does not matter
+in the local case. However, when you export a remote service, you should expose a specific
+service interface, with specific operations intended for remote usage. Besides internal
+callback interfaces, the target might implement multiple business interfaces, with only
+one of them intended for remote exposure. For these reasons, we require such a
+service interface to be specified.
+
+This is a trade-off between configuration convenience and the risk of accidental
+exposure of internal methods. Always specifying a service interface is not too much
+effort and puts you on the safe side regarding controlled exposure of specific methods.
+====
+
+
+
+[[remoting-considerations]]
+=== Considerations when Choosing a Technology
+
+Each and every technology presented here has its drawbacks. When choosing a technology,
+you should carefully consider your needs, the services you expose, and the objects you
+send over the wire.
+
+When using RMI, you cannot access the objects through the HTTP protocol,
+unless you tunnel the RMI traffic. RMI is a fairly heavy-weight protocol, in that it
+supports full-object serialization, which is important when you use a complex data model
+that needs serialization over the wire. However, RMI-JRMP is tied to Java clients. It is
+a Java-to-Java remoting solution.
+
+Spring's HTTP invoker is a good choice if you need HTTP-based remoting but also rely on
+Java serialization. It shares the basic infrastructure with RMI invokers but uses
+HTTP as transport. Note that HTTP invokers are not limited only to Java-to-Java remoting
+but also to Spring on both the client and the server side. (The latter also applies to
+Spring's RMI invoker for non-RMI interfaces.)
+
+Hessian might provide significant value when operating in a heterogeneous environment,
+because they explicitly allow for non-Java clients. However, non-Java support is still
+limited. Known issues include the serialization of Hibernate objects in combination with
+lazily-initialized collections. If you have such a data model, consider using RMI or
+HTTP invokers instead of Hessian.
+
+JMS can be useful for providing clusters of services and letting the JMS broker take
+care of load balancing, discovery, and auto-failover. By default, Java serialization is
+used for JMS remoting, but the JMS provider could use a different mechanism for
+the wire formatting, such as XStream to let servers be implemented in other
+technologies.
+
+Last but not least, EJB has an advantage over RMI, in that it supports standard
+role-based authentication and authorization and remote transaction propagation. It is
+possible to get RMI invokers or HTTP invokers to support security context propagation as
+well, although this is not provided by core Spring. Spring offers only appropriate hooks
+for plugging in third-party or custom solutions.

-[[remoting-jms-client]]
-==== Client-side Configuration
 
-The client merely needs to create a client-side proxy that implements the agreed-upon
-interface (`CheckingAccountService`).
 
-The following example defines beans that you can inject into other client-side objects
-(and the proxy takes care of forwarding the call to the server-side object via JMS):
+
+[[remoting-rmi]]
+=== RMI (Deprecated)
+
+WARNING: As of Spring Framework 5.3, RMI support is deprecated and will not be replaced.
+
+By using Spring's support for RMI, you can transparently expose your services through the
+RMI infrastructure. After having this set up, you basically have a configuration similar
+to remote EJBs, except for the fact that there is no standard support for security
+context propagation or remote transaction propagation. Spring does provide hooks for
+such additional invocation context when you use the RMI invoker, so you can, for example,
+plug in security frameworks or custom security credentials.
+
+
+[[remoting-rmi-server]]
+==== Exporting the Service by Using `RmiServiceExporter`
+
+Using the `RmiServiceExporter`, we can expose the interface of our AccountService object
+as RMI object. The interface can be accessed by using `RmiProxyFactoryBean`, or via
+plain RMI in case of a traditional RMI service. The `RmiServiceExporter` explicitly
+supports the exposing of any non-RMI services via RMI invokers.
+
+We first have to set up our service in the Spring container.
+The following example shows how to do so:
 
 [source,xml,indent=0]
 [subs="verbatim,quotes"]
 ----
-	<?xml version="1.0" encoding="UTF-8"?>

+	<bean id="accountService" class="example.AccountServiceImpl">
+		<!-- any additional properties, maybe a DAO? -->
+	</bean>
+----
 
-		<bean id="checkingAccountService"
-				class="org.springframework.jms.remoting.JmsInvokerProxyFactoryBean">
-			<property name="serviceInterface" value="com.foo.CheckingAccountService"/>
-			<property name="connectionFactory" ref="connectionFactory"/>
-			<property name="queue" ref="queue"/>
-		</bean>
+Next, we have to expose our service by using `RmiServiceExporter`.
+The following example shows how to do so:
 
-	</beans>
+[source,xml,indent=0]
+[subs="verbatim,quotes"]
+----
+	<bean class="org.springframework.remoting.rmi.RmiServiceExporter">
+		<!-- does not necessarily have to be the same name as the bean to be exported -->
+		<property name="serviceName" value="AccountService"/>
+		<property name="service" ref="accountService"/>
+		<property name="serviceInterface" value="example.AccountService"/>
+		<!-- defaults to 1099 -->
+		<property name="registryPort" value="1199"/>
+	</bean>
 ----
 
+In the preceding example, we override the port for the RMI registry. Often, your application
+server also maintains an RMI registry, and it is wise to not interfere with that one.
+Furthermore, the service name is used to bind the service. So, in the preceding example, the
+service is bound at `'rmi://HOST:1199/AccountService'`. We use this URL later on to link in
+the service at the client side.
+
+NOTE: The `servicePort` property has been omitted (it defaults to 0). This means that an
+anonymous port is used to communicate with the service.
+
+
+[[remoting-rmi-client]]
+==== Linking in the Service at the Client
+
+Our client is a simple object that uses the `AccountService` to manage accounts,

-			CheckingAccountService service = (CheckingAccountService) ctx.getBean("checkingAccountService");
-			service.cancelAccount(new Long(10));
+		public void setAccountService(AccountService accountService) {
+			this.accountService = accountService;
 		}
+
+		// additional methods using the accountService
 	}
 ----
 
+To link in the service on the client, we create a separate Spring container,
+to contain the following simple object and the service linking configuration bits:

-[[remoting-autodection-remote-interfaces]]
-[NOTE]
-====
-Auto-detection is not implemented for remote interfaces
+That is all we need to do to support the remote account service on the client. Spring
+transparently creates an invoker and remotely enables the account service through the
+`RmiServiceExporter`. At the client, we link it in by using the `RmiProxyFactoryBean`.
 
-The main reason why auto-detection of implemented interfaces does not occur for remote
-interfaces is to avoid opening too many doors to remote callers. The target object might
-implement internal callback interfaces, such as `InitializingBean` or `DisposableBean`
-which one would not want to expose to callers.
 
-Offering a proxy with all interfaces implemented by the target usually does not matter
-in the local case. However, when you export a remote service, you should expose a specific
-service interface, with specific operations intended for remote usage. Besides internal
-callback interfaces, the target might implement multiple business interfaces, with only
-one of them intended for remote exposure. For these reasons, we require such a
-service interface to be specified.
 
-This is a trade-off between configuration convenience and the risk of accidental
-exposure of internal methods. Always specifying a service interface is not too much
-effort and puts you on the safe side regarding controlled exposure of specific methods.

+[[remoting-caucho-protocols]]
+=== Using Hessian to Remotely Call Services through HTTP (Deprecated)
 
+WARNING: As of Spring Framework 5.3, Hessian support is deprecated and will not be replaced.
 
+Hessian offers a binary HTTP-based remoting protocol. It is developed by Caucho,
+and you can find more information about Hessian itself at https://www.caucho.com/[].
 
-[[remoting-considerations]]
-=== Considerations when Choosing a Technology
 
-Each and every technology presented here has its drawbacks. When choosing a technology,
-you should carefully consider your needs, the services you expose, and the objects you
-send over the wire.
+[[remoting-caucho-protocols-hessian]]
+==== Hessian
 
-When using RMI, you cannot access the objects through the HTTP protocol,
-unless you tunnel the RMI traffic. RMI is a fairly heavy-weight protocol, in that it
-supports full-object serialization, which is important when you use a complex data model
-that needs serialization over the wire. However, RMI-JRMP is tied to Java clients. It is
-a Java-to-Java remoting solution.
+Hessian communicates through HTTP and does so by using a custom servlet. By using Spring's
+`DispatcherServlet` principles (see <<webmvc.adoc#mvc-servlet>>), we can wire up such a
+servlet to expose your services. First, we have to create a new servlet in our application,
+as shown in the following excerpt from `web.xml`:
 
-Spring's HTTP invoker is a good choice if you need HTTP-based remoting but also rely on
-Java serialization. It shares the basic infrastructure with RMI invokers but uses
-HTTP as transport. Note that HTTP invokers are not limited only to Java-to-Java remoting
-but also to Spring on both the client and the server side. (The latter also applies to
-Spring's RMI invoker for non-RMI interfaces.)
+[source,xml,indent=0]
+[subs="verbatim,quotes"]
+----
+	<servlet>
+		<servlet-name>remoting</servlet-name>
+		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
+		<load-on-startup>1</load-on-startup>
+	</servlet>
 
-Hessian might provide significant value when operating in a heterogeneous environment,
-because they explicitly allow for non-Java clients. However, non-Java support is still
-limited. Known issues include the serialization of Hibernate objects in combination with
-lazily-initialized collections. If you have such a data model, consider using RMI or
-HTTP invokers instead of Hessian.
+	<servlet-mapping>
+		<servlet-name>remoting</servlet-name>
+		<url-pattern>/remoting/*</url-pattern>
+	</servlet-mapping>
+----
 
-JMS can be useful for providing clusters of services and letting the JMS broker take
-care of load balancing, discovery, and auto-failover. By default, Java serialization is
-used for JMS remoting, but the JMS provider could use a different mechanism for
-the wire formatting, such as XStream to let servers be implemented in other
-technologies.
+If you are familiar with Spring's `DispatcherServlet` principles, you probably
+know that now you have to create a Spring container configuration resource named
+`remoting-servlet.xml` (after the name of your servlet) in the `WEB-INF` directory.
+The application context is used in the next section.
 
-Last but not least, EJB has an advantage over RMI, in that it supports standard
-role-based authentication and authorization and remote transaction propagation. It is
-possible to get RMI invokers or HTTP invokers to support security context propagation as
-well, although this is not provided by core Spring. Spring offers only appropriate hooks
-for plugging in third-party or custom solutions.
+Alternatively, consider the use of Spring's simpler `HttpRequestHandlerServlet`. Doing so
+lets you embed the remote exporter definitions in your root application context (by
+default, in `WEB-INF/applicationContext.xml`), with individual servlet definitions
+pointing to specific exporter beans. In this case, each servlet name needs to match the bean name of
+its target exporter.

+==== Exposing Your Beans by Using `HessianServiceExporter`
 
-[[rest-client-access]]
-=== REST Endpoints
+In the newly created application context called `remoting-servlet.xml`, we create a
+`HessianServiceExporter` to export our services, as the following example shows:
+
+[source,xml,indent=0]
+[subs="verbatim,quotes"]
+----
+	<bean id="accountService" class="example.AccountServiceImpl">
+		<!-- any additional properties, maybe a DAO? -->
+	</bean>
 
-The Spring Framework provides two choices for making calls to REST endpoints:
+	<bean name="/AccountService" class="org.springframework.remoting.caucho.HessianServiceExporter">
+		<property name="service" ref="accountService"/>
+		<property name="serviceInterface" value="example.AccountService"/>
+	</bean>
+----
 
-* <<rest-resttemplate>>: The original Spring REST client with a synchronous, template
-method API.
-* <<web-reactive.adoc#webflux-client, WebClient>>: a non-blocking, reactive alternative
-that supports both synchronous and asynchronous as well as streaming scenarios.
+Now we are ready to link in the service at the client. No explicit handler mapping is
+specified (to map request URLs onto services), so we use `BeanNameUrlHandlerMapping`
+used. Hence, the service is exported at the URL indicated through its bean name
+within the containing `DispatcherServlet` instance's mapping (as defined earlier):
+`https://HOST:8080/remoting/AccountService`.
 
-NOTE: As of 5.0 the `RestTemplate` is in maintenance mode, with only minor requests for
-changes and bugs to be accepted going forward. Please, consider using the
-<<web-reactive.adoc#webflux-client, WebClient>> which offers a more modern API and
-supports sync, async, and streaming scenarios.
+Alternatively, you can create a `HessianServiceExporter` in your root application context (for example,
+in `WEB-INF/applicationContext.xml`), as the following example shows:
 
+[source,xml,indent=0]
+[subs="verbatim,quotes"]
+----
+	<bean name="accountExporter" class="org.springframework.remoting.caucho.HessianServiceExporter">
+		<property name="service" ref="accountService"/>
+		<property name="serviceInterface" value="example.AccountService"/>
+	</bean>
+----
 
-[[rest-resttemplate]]
-==== `RestTemplate`
+In the latter case, you should define a corresponding servlet for this exporter in `web.xml`,
+with the same end result: The exporter gets mapped to the request path at
+`/remoting/AccountService`. Note that the servlet name needs to match the bean name of
+the target exporter. The following example shows how to do so:
 
-The `RestTemplate` provides a higher level API over HTTP client libraries. It makes it
-easy to invoke REST endpoints in a single line. It exposes the following groups of
-overloaded methods:
+[source,xml,indent=0]
+[subs="verbatim,quotes"]

-| `headForHeaders`
-| Retrieves all headers for a resource by using HEAD.
+By using the `HessianProxyFactoryBean`, we can link in the service at the client. The same

+application context and mention the following beans where the `SimpleObject` is by using
+the `AccountService` to manage accounts, as the following example shows:
 
-| `postForLocation`
-| Creates a new resource by using POST and returns the `Location` header from the response.

+[[remoting-caucho-protocols-security]]
+==== Applying HTTP Basic Authentication to a Service Exposed through Hessian
 
-| `patchForObject`
-| Updates a resource by using PATCH and returns the representation from the response.
-Note that the JDK `HttpURLConnection` does not support the `PATCH`, but Apache
-HttpComponents and others do.
+One of the advantages of Hessian is that we can easily apply HTTP basic authentication,
+because both protocols are HTTP-based. Your normal HTTP server security mechanism can
+be applied through using the `web.xml` security features, for example. Usually,
+you need not use per-user security credentials here. Rather, you can use shared credentials that you define
+at the `HessianProxyFactoryBean` level (similar to a JDBC `DataSource`), as the following example shows:
 
-| `delete`
-| Deletes the resources at the specified URI by using DELETE.
+[source,xml,indent=0]
+[subs="verbatim,quotes"]
+----
+	<bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping">
+		<property name="interceptors" ref="authorizationInterceptor"/>

-| `optionsForAllow`
-| Retrieves allowed HTTP methods for a resource by using ALLOW.
+	<bean id="authorizationInterceptor"
+			class="org.springframework.web.servlet.handler.UserRoleAuthorizationInterceptor">
+		<property name="authorizedRoles" value="administrator,operator"/>
+	</bean>
+----
 
-| `exchange`
-| More generalized (and less opinionated) version of the preceding methods that provides extra
-flexibility when needed. It accepts a `RequestEntity` (including HTTP method, URL, headers,
-and body as input) and returns a `ResponseEntity`.
+In the preceding example, we explicitly mention the `BeanNameUrlHandlerMapping` and set
+an interceptor, to let only administrators and operators call the beans mentioned in
+this application context.
 
-These methods allow the use of `ParameterizedTypeReference` instead of `Class` to specify
-a response type with generics.
+NOTE: The preceding example does not show a flexible kind of security infrastructure. For
+more options as far as security is concerned, have a look at the Spring Security project
+at https://projects.spring.io/spring-security/.

+[[remoting-httpinvoker]]
+=== Spring HTTP Invoker (Deprecated)
 
-The default constructor uses `java.net.HttpURLConnection` to perform requests. You can
-switch to a different HTTP library with an implementation of `ClientHttpRequestFactory`.
-There is built-in support for the following:
+WARNING: As of Spring Framework 5.3, HTTP Invoker support is deprecated and will not be replaced.
 
-* Apache HttpComponents
-* Netty
-* OkHttp
+As opposed to Hessian, Spring HTTP invokers are both lightweight protocols that use their own slim
+serialization mechanisms and use the standard Java serialization
+mechanism to expose services through HTTP. This has a huge advantage if your arguments
+and return types are complex types that cannot be serialized by using the serialization
+mechanisms Hessian uses (see the next section for more considerations when
+you choose a remoting technology).
 
-For example, to switch to Apache HttpComponents, you can use the following:
+Under the hood, Spring uses either the standard facilities provided by the JDK or
+Apache `HttpComponents` to perform HTTP calls. If you need more
+advanced and easier-to-use functionality, use the latter. See

+[CAUTION]
+====
+Be aware of vulnerabilities due to unsafe Java deserialization:
+Manipulated input streams can lead to unwanted code execution on the server
+during the deserialization step. As a consequence, do not expose HTTP invoker
+endpoints to untrusted clients. Rather, expose them only between your own services.
+In general, we strongly recommend using any other message format (such as JSON) instead.
 
-Each `ClientHttpRequestFactory` exposes configuration options specific to the underlying
-HTTP client library -- for example, for credentials, connection pooling, and other details.
+If you are concerned about security vulnerabilities due to Java serialization,
+consider the general-purpose serialization filter mechanism at the core JVM level,
+originally developed for JDK 9 but backported to JDK 8, 7 and 6 in the meantime. See
+https://blogs.oracle.com/java-platform-group/entry/incoming_filter_serialization_data_a
+and https://openjdk.java.net/jeps/290.
+====
 
-TIP: Note that the `java.net` implementation for HTTP requests can raise an exception when
-accessing the status of a response that represents an error (such as 401). If this is an
-issue, switch to another HTTP client library.
 
-[[rest-resttemplate-uri]]
-===== URIs
+[[remoting-httpinvoker-server]]
+==== Exposing the Service Object
 
-Many of the `RestTemplate` methods accept a URI template and URI template variables,
-either as a `String` variable argument, or as `Map<String,String>`.
+Setting up the HTTP invoker infrastructure for a service object closely resembles the
+way you would do the same by using Hessian. As Hessian support provides
+`HessianServiceExporter`, Spring's HttpInvoker support provides
+`org.springframework.remoting.httpinvoker.HttpInvokerServiceExporter`.
 
-The following example uses a `String` variable argument:
+To expose the `AccountService` (mentioned earlier) within a Spring Web MVC
+`DispatcherServlet`, the following configuration needs to be in place in the
+dispatcher's application context, as the following example shows:
 
-[source,java,indent=0]

+		<property name="service" ref="accountService"/>
+		<property name="serviceInterface" value="example.AccountService"/>
+	</bean>
 ----
 
-The following example uses a `Map<String, String>`:
+Such an exporter definition is exposed through the `DispatcherServlet` instance's standard
+mapping facilities, as explained in <<remoting-caucho-protocols, the section on Hessian>>.
 
-[source,java,indent=0]
+Alternatively, you can create an `HttpInvokerServiceExporter` in your root application context
+(for example, in `'WEB-INF/applicationContext.xml'`), as the following example shows:
+
+[source,xml,indent=0]

-Keep in mind URI templates are automatically encoded, as the following example shows:

-===== Headers
+[[remoting-httpinvoker-client]]
+==== Linking in the Service at the Client
 
-You can use the `exchange()` methods to specify request headers, as the following example shows:
+Again, linking in the service from the client much resembles the way you would do it
+when you use Hessian. By using a proxy, Spring can translate your calls to
+HTTP POST requests to the URL that points to the exported service. The following example
+shows how to configure this arrangement:
 
-[source,java,indent=0]
+[source,xml,indent=0]
 [subs="verbatim,quotes"]
 ----
-	String uriTemplate = "https://example.com/hotels/{hotel}";
-	URI uri = UriComponentsBuilder.fromUriString(uriTemplate).build(42);
-
-	RequestEntity<Void> requestEntity = RequestEntity.get(uri)
-			.header(("MyRequestHeader", "MyValue")
-			.build();
-
-	ResponseEntity<String> response = template.exchange(requestEntity, String.class);
-
-	String responseHeader = response.getHeaders().getFirst("MyResponseHeader");
-	String body = response.getBody();
+	<bean id="httpInvokerProxy" class="org.springframework.remoting.httpinvoker.HttpInvokerProxyFactoryBean">
+		<property name="serviceUrl" value="https://remotehost:8080/remoting/AccountService"/>
+		<property name="serviceInterface" value="example.AccountService"/>
+	</bean>
 ----
 
-You can obtain response headers through many `RestTemplate` method variants that return
-`ResponseEntity`.
+As mentioned earlier, you can choose what HTTP client you want to use. By default, the
+`HttpInvokerProxy` uses the JDK's HTTP functionality, but you can also use the Apache
+`HttpComponents` client by setting the `httpInvokerRequestExecutor` property.
+The following example shows how to do so:
 
-[[rest-template-body]]
-===== Body
+[source,xml,indent=0]
+[subs="verbatim,quotes"]
+----
+	<property name="httpInvokerRequestExecutor">
+		<bean class="org.springframework.remoting.httpinvoker.HttpComponentsHttpInvokerRequestExecutor"/>
+	</property>
+----
 
-Objects passed into and returned from `RestTemplate` methods are converted to and from raw
-content with the help of an `HttpMessageConverter`.
 
-On a POST, an input object is serialized to the request body, as the following example shows:
 
-----
-URI location = template.postForLocation("https://example.com/people", person);
-----
+[[remoting-jms]]
+=== JMS (Deprecated)
 
-You need not explicitly set the Content-Type header of the request. In most cases,
-you can find a compatible message converter based on the source `Object` type, and the chosen
-message converter sets the content type accordingly. If necessary, you can use the
-`exchange` methods to explicitly provide the `Content-Type` request header, and that, in
-turn, influences what message converter is selected.
+WARNING: As of Spring Framework 5.3, JMS remoting support is deprecated and will not be replaced.
 
-On a GET, the body of the response is deserialized to an output `Object`, as the following example shows:
+You can also expose services transparently by using JMS as the underlying communication
+protocol. The JMS remoting support in the Spring Framework is pretty basic. It sends
+and receives on the `same thread` and in the same non-transactional `Session`.
+As a result, throughput is implementation-dependent. Note that these single-threaded
+and non-transactional constraints apply only to Spring's JMS remoting support.
+See <<jms>> for information on Spring's rich support for JMS-based messaging.
 
+The following interface is used on both the server and the client sides:
+
+[source,java,indent=0]
+[subs="verbatim,quotes"]
 ----
-Person person = restTemplate.getForObject("https://example.com/people/{id}", Person.class, 42);
-----
+	package com.foo;
 
-The `Accept` header of the request does not need to be explicitly set. In most cases,
-a compatible message converter can be found based on the expected response type, which
-then helps to populate the `Accept` header. If necessary, you can use the `exchange`
-methods to provide the `Accept` header explicitly.
+	public interface CheckingAccountService {
 
-By default, `RestTemplate` registers all built-in
-<<rest-message-conversion, message converters>>, depending on classpath checks that help
-to determine what optional conversion libraries are present. You can also set the message
-converters to use explicitly.
+		public void cancelAccount(Long accountId);
+	}
+----
 
-[[rest-message-conversion]]
-===== Message Conversion
-[.small]#<<web-reactive.adoc#webflux-codecs, WebFlux>>#
+The following simple implementation of the preceding interface is used on the server-side:
 
-The `spring-web` module contains the `HttpMessageConverter` contract for reading and
-writing the body of HTTP requests and responses through `InputStream` and `OutputStream`.
-`HttpMessageConverter` instances are used on the client side (for example, in the `RestTemplate`) and
-on the server side (for example, in Spring MVC REST controllers).
+[source,java,indent=0]
+[subs="verbatim,quotes"]
+----
+	package com.foo;
 
-Concrete implementations for the main media (MIME) types are provided in the framework
-and are, by default, registered with the `RestTemplate` on the client side and with
-`RequestMethodHandlerAdapter` on the server side (see
-<<web.adoc#mvc-config-message-converters, Configuring Message Converters>>).
+	public class SimpleCheckingAccountService implements CheckingAccountService {
 
-The implementations of `HttpMessageConverter` are described in the following sections.
-For all converters, a default media type is used, but you can override it by setting the
-`supportedMediaTypes` bean property. The following table describes each implementation:
+		public void cancelAccount(Long accountId) {
+			System.out.println("Cancelling account [" + accountId + "]");
+		}
+	}

-.HttpMessageConverter Implementations
-[cols="1,3"]
-|===
-| MessageConverter | Description
+The following configuration file contains the JMS-infrastructure beans that are shared
+on both the client and the server:
 
-| `StringHttpMessageConverter`
-| An `HttpMessageConverter` implementation that can read and write `String` instances from the HTTP
-request and response. By default, this converter supports all text media types
-(`text/{asterisk}`) and writes with a `Content-Type` of `text/plain`.
+[source,xml,indent=0]
+[subs="verbatim,quotes"]
+----
+	<?xml version="1.0" encoding="UTF-8"?>
+	<beans xmlns="http://www.springframework.org/schema/beans"
+		xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+		xsi:schemaLocation="http://www.springframework.org/schema/beans
+			https://www.springframework.org/schema/beans/spring-beans.xsd">
 
-| `FormHttpMessageConverter`
-| An `HttpMessageConverter` implementation that can read and write form data from the HTTP
-request and response. By default, this converter reads and writes the
-`application/x-www-form-urlencoded` media type. Form data is read from and written into a
-`MultiValueMap<String, String>`. The converter can also write (but not read) multipart
-data read from a `MultiValueMap<String, Object>`. By default, `multipart/form-data` is
-supported. As of Spring Framework 5.2, additional multipart subtypes can be supported for
-writing form data. Consult the javadoc for `FormHttpMessageConverter` for further details.
+		<bean id="connectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
+			<property name="brokerURL" value="tcp://ep-t43:61616"/>
+		</bean>
 
-| `ByteArrayHttpMessageConverter`
-| An `HttpMessageConverter` implementation that can read and write byte arrays from the
-HTTP request and response. By default, this converter supports all media types (`{asterisk}/{asterisk}`)
-and writes with a `Content-Type` of `application/octet-stream`. You can override this
-by setting the `supportedMediaTypes` property and overriding `getContentType(byte[])`.
+		<bean id="queue" class="org.apache.activemq.command.ActiveMQQueue">
+			<constructor-arg value="mmm"/>
+		</bean>
 
-| `MarshallingHttpMessageConverter`
-| An `HttpMessageConverter` implementation that can read and write XML by using Spring's
-`Marshaller` and `Unmarshaller` abstractions from the `org.springframework.oxm` package.
-This converter requires a `Marshaller` and `Unmarshaller` before it can be used. You can inject these
-through constructor or bean properties. By default, this converter supports
-`text/xml` and `application/xml`.
+	</beans>
+----
 
-| `MappingJackson2HttpMessageConverter`
-| An `HttpMessageConverter` implementation that can read and write JSON by using Jackson's
-`ObjectMapper`. You can customize JSON mapping as needed through the use of Jackson's
-provided annotations. When you need further control (for cases where custom JSON
-serializers/deserializers need to be provided for specific types), you can inject a custom `ObjectMapper`
-through the `ObjectMapper` property. By default, this
-converter supports `application/json`.
 
-| `MappingJackson2XmlHttpMessageConverter`
-| An `HttpMessageConverter` implementation that can read and write XML by using
-https://github.com/FasterXML/jackson-dataformat-xml[Jackson XML] extension's
-`XmlMapper`. You can customize XML mapping as needed through the use of JAXB
-or Jackson's provided annotations. When you need further control (for cases where custom XML
-serializers/deserializers need to be provided for specific types), you can inject a custom `XmlMapper`
-through the `ObjectMapper` property. By default, this
-converter supports `application/xml`.
+[[remoting-jms-server]]
+==== Server-side Configuration
 
-| `SourceHttpMessageConverter`
-| An `HttpMessageConverter` implementation that can read and write
-`javax.xml.transform.Source` from the HTTP request and response. Only `DOMSource`,
-`SAXSource`, and `StreamSource` are supported. By default, this converter supports
-`text/xml` and `application/xml`.
+On the server, you need to expose the service object that uses the
+`JmsInvokerServiceExporter`, as the following example shows:
 
-| `BufferedImageHttpMessageConverter`
-| An `HttpMessageConverter` implementation that can read and write
-`java.awt.image.BufferedImage` from the HTTP request and response. This converter reads
-and writes the media type supported by the Java I/O API.

 ----
-	MappingJacksonValue value = new MappingJacksonValue(new User("eric", "7!jd#h23"));
-	value.setSerializationView(User.WithoutPasswordView.class);
+	package com.foo;
 
-	RequestEntity<MappingJacksonValue> requestEntity =
-		RequestEntity.post(new URI("https://example.com/user")).body(value);
+	import org.springframework.context.support.ClassPathXmlApplicationContext;

+	public class Server {
+
+		public static void main(String[] args) throws Exception {
+			new ClassPathXmlApplicationContext("com/foo/server.xml", "com/foo/jms.xml");
+		}
+	}
 ----
 
-[[rest-template-multipart]]
-===== Multipart
 
-To send multipart data, you need to provide a `MultiValueMap<String, Object>` whose values
-may be an `Object` for part content, a `Resource` for a file part, or an `HttpEntity` for
-part content with headers. For example:
+[[remoting-jms-client]]
+==== Client-side Configuration
 
-[source,java,intent=0]
-[subs="verbatim,quotes"]
-----
-	MultiValueMap<String, Object> parts = new LinkedMultiValueMap<>();
+The client merely needs to create a client-side proxy that implements the agreed-upon
+interface (`CheckingAccountService`).
 
-	parts.add("fieldPart", "fieldValue");
-	parts.add("filePart", new FileSystemResource("...logo.png"));
-	parts.add("jsonPart", new Person("Jason"));
+The following example defines beans that you can inject into other client-side objects
+(and the proxy takes care of forwarding the call to the server-side object via JMS):
 
-	HttpHeaders headers = new HttpHeaders();
-	headers.setContentType(MediaType.APPLICATION_XML);
-	parts.add("xmlPart", new HttpEntity<>(myBean, headers));
+[source,xml,indent=0]
+[subs="verbatim,quotes"]
 ----
+	<?xml version="1.0" encoding="UTF-8"?>
+	<beans xmlns="http://www.springframework.org/schema/beans"
+		xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+		xsi:schemaLocation="http://www.springframework.org/schema/beans
+			https://www.springframework.org/schema/beans/spring-beans.xsd">
 
-In most cases, you do not have to specify the `Content-Type` for each part. The content
-type is determined automatically based on the `HttpMessageConverter` chosen to serialize
-it or, in the case of a `Resource` based on the file extension. If necessary, you can
-explicitly provide the `MediaType` with an `HttpEntity` wrapper.
+		<bean id="checkingAccountService"
+				class="org.springframework.jms.remoting.JmsInvokerProxyFactoryBean">
+			<property name="serviceInterface" value="com.foo.CheckingAccountService"/>
+			<property name="connectionFactory" ref="connectionFactory"/>
+			<property name="queue" ref="queue"/>
+		</bean>
 
-Once the `MultiValueMap` is ready, you can pass it to the `RestTemplate`, as show below:
+	</beans>
+----
 
-[source,java,intent=0]
+[source,java,indent=0]
 [subs="verbatim,quotes"]
 ----
-	MultiValueMap<String, Object> parts = ...;
-	template.postForObject("https://example.com/upload", parts, Void.class);
-----
-
-If the `MultiValueMap` contains at least one non-`String` value, the `Content-Type` is set
-to `multipart/form-data` by the `FormHttpMessageConverter`. If the `MultiValueMap` has
-`String` values the `Content-Type` is defaulted to `application/x-www-form-urlencoded`.
-If necessary the `Content-Type` may also be set explicitly.
+	package com.foo;
 
+	import org.springframework.context.ApplicationContext;
+	import org.springframework.context.support.ClassPathXmlApplicationContext;
 
-[[rest-async-resttemplate]]
-==== Using `AsyncRestTemplate` (Deprecated)
+	public class Client {
 
-The `AsyncRestTemplate` is deprecated. For all use cases where you might consider using
-`AsyncRestTemplate`, use the <<web-reactive.adoc#webflux-client, WebClient>> instead.
+		public static void main(String[] args) throws Exception {
+			ApplicationContext ctx = new ClassPathXmlApplicationContext("com/foo/client.xml", "com/foo/jms.xml");
+			CheckingAccountService service = (CheckingAccountService) ctx.getBean("checkingAccountService");
+			service.cancelAccount(new Long(10));
+		}

-To obtain an `RSocketRequester` on the client side requires connecting to a server along with

+To obtain an `RSocketRequester` on the client side is to connect to a server which involves
+sending an RSocket `SETUP` frame with connection settings. `RSocketRequester` provides a
+builder that helps to prepare an `io.rsocket.core.RSocketConnector` including connection
+settings for the `SETUP` frame.
 
 This is the most basic way to connect with default settings:

Subject: [PATCH 1153/2315] Allow auto grow for entries w/o default constructor
 in SpEL

Prior to this commit, The "auto grow" feature in SpEL expressions only
worked for element types with a default constructor. For example, auto
grow did not work for a list of BigDecimal elements.

This commit inserts a null value in the list when no default
constructor can be found for the element type.

Subject: [PATCH 1197/2315] Match subscriptions to remove by id

Commit 524ca1a6767a8912e1a4c58c797e5099794b442b unintentionally changed
how subscriptions to be removed are matched. This commit restores that.

Subject: [PATCH 1198/2315] Provide access to underlying RSocketClient

The recently introduced support for RSocketClient in commit
7c982511426eebea3d34730ab128bb39a55a9de6 did not expose the underlying
client in order to avoid a hard dependency on RSocket 1.1 for the time
being. However such access appears to be necessary, e.g. for Spring
Integration, where the connection needs to be established (warmed up)
ahead of actual requests.

See gh-25332

Subject: [PATCH 1208/2315] Avoid infinite loop in AnnotationScanner

Prior to this commit, scanning for annotations resulted in an infinite
loop when using the INHERITED_ANNOTATIONS search strategy and a class
filter that filters out visited classes.

This commit avoids an infinite loop in AnnotationsScanner's
processClassInheritedAnnotations(...) method by skipping the current
level of the class hierarchy when the current source class has been
filtered out.

Closes gh-25429

Subject: [PATCH 1212/2315] Support multiple Content-Language values in
 MockHttpServletResponse

Prior to this commit, if the user supplied a comma-separated list such
as "en, it" as the Content-Language header value to
MockHttpServletResponse's setHeader() method, only the first language
was actually set in the response's Content-Language header (e.g., "en").

This commit ensures that all supplied content languages are set in the
response's Content-Language header.

Closes gh-25281

Subject: [PATCH 1215/2315] Add application startup metrics support

This commit adds a new `StartupStep` interface and its factory
`ApplicationStartup`. Such steps are created, tagged with metadata and
thir execution time can be recorded - in order to collect metrics about
the application startup.

The default implementation is a "no-op" variant and has no side-effect.
Other implementations can record and collect events in a dedicated
metrics system or profiling tools. We provide here an implementation for
recording and storing steps with Java Flight Recorder.

This commit also instruments the Spring application context to gather
metrics about various phases of the application context, such as:

* context refresh phase
* bean definition registry post-processing
* bean factory post-processing
* beans instantiation and post-processing

Third part libraries involved in the Spring application context can
reuse the same infrastructure to record similar metrics.

Closes gh-24878

+[[context-functionality-startup]]
+=== Application Startup tracking
 
+The `ApplicationContext` manages the lifecycle of Spring applications and provides a rich
+programming model around components. As a result, complex applications can have equally
+complex component graphs and startup phases.
+
+Tracking the application startup steps with specific metrics can help understand where
+time is being spent during the startup phase, but it can also be used as a way to better
+understand the context lifecycle as a whole.
+
+The `AbstractApplicationContext` (and its subclasses) is instrumented with an
+`ApplicationStartup`, which collects `StartupStep` data about various startup phases:
+
+* application context lifecycle (base packages scanning, config classes management)
+* beans lifecycle (instantiation, smart initialization, post processing)
+* application events processing
+
+Here is an example of instrumentation in the `AnnotationConfigApplicationContext`:
+
+[source,java,indent=0,subs="verbatim,quotes",role="primary"]
+.Java
+----
+	// create a startup step and start recording
+	StartupStep scanPackages = this.getApplicationStartup().start("spring.context.base-packages.scan");
+	// add tagging information to the current step
+	scanPackages.tag("packages", () -> Arrays.toString(basePackages));
+	// perform the actual phase we're instrumenting
+	this.scanner.scan(basePackages);
+	// end the current step
+	scanPackages.end();
+----
+[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
+.Kotlin
+----
+	// create a startup step and start recording
+	val scanPackages = this.getApplicationStartup().start("spring.context.base-packages.scan");
+	// add tagging information to the current step
+	scanPackages.tag("packages", () -> Arrays.toString(basePackages));
+	// perform the actual phase we're instrumenting
+	this.scanner.scan(basePackages);
+	// end the current step
+	scanPackages.end();
+----
+
+The application context is already instrumented with multiple steps.
+Once recorded, these startup steps can be collected, displayed and analyzed with specific tools.
+For a complete list of existing startup steps, you can check out the
+<<application-startup-steps, dedicated appendix section>>.
+
+The default `ApplicationStartup` implementation is a no-op variant, for minimal overhead.
+This means no metrics will be collected during application startup by default.
+Spring Framework ships with an implementation for tracking startup steps with Java Flight Recorder:
+`FlightRecorderApplicationStartup`. To use this variant, you must configure an instance of it
+to the `ApplicationContext` as soon as it's been created.
+
+Developers can also use the `ApplicationStartup` infrastructure if they're providing their own
+`AbstractApplicationContext` subclass, or if they wish to collect more precise data.
+
+WARNING: `ApplicationStartup` is meant to be only used during application startup and for
+the core container; this is by no means a replacement for Java profilers or
+metrics libraries like https://micrometer.io[Micrometer].
+
+To start collecting custom `StartupStep`, components can either get the `ApplicationStartup`
+instance from the application context directly, make their component implement `ApplicationStartupAware`,
+or ask for the `ApplicationStartup` type on any injection point.
+
+NOTE: Developers should not use the `"spring.*"` namespace when creating custom startup steps.
+This namespace is reserved for internal Spring usage and is subject to change.

Subject: [PATCH 1217/2315] Remove unused class filtering support in
 AnnotationScanner

PR gh-25429 brought it to our attention that there was a bug in
AnnotationScanner when using a non-null class filter that filtered out
classes; however, it turns out that there is no production code that
utilizes the package-private class filtering support.

This commit therefore removes all class filtering support from
AnnotationScanner since that functionality is effectively unused.

Closes gh-25477

Subject: [PATCH 1234/2315] Update Reactor Netty modules

Since reactor/reactor-netty#739, the `reactor-netty` module is now split
into two: `reactor-netty-core` and `reactor-netty-http`.

This commit updates the Spring Framework build accordingly.

Subject: [PATCH 1238/2315] Reset charset field in MockHttpServletResponse

Prior to this commit, calling reset() on MockHttpServletResponse did not
reset the `charset` field to `false` which could result in the
"Content-Type" header containing `;charset=null` which in turn would
result in errors when parsing the "Content-Type" header.

This commit resets the charset field to `false` in
MockHttpServletResponse's reset() method to avoid such errors.

Closes gh-25501

Subject: [PATCH 1240/2315] Fix error message for type mismatch in
 jsonPath().value()

Prior to this commit, if a value existed at the specified JSON path but
had an incompatible type, the AssertionError thrown contained a message
stating that the value did not exist (i.e., "No Value at JSON Path"),
which was not only misleading but also technically incorrect.

This commit fixes the error message for such use cases. For example, the
AssertionError thrown in such use cases now resembles the following.

  At JSON path "$.name", value <Lisa> of type <java.lang.String> cannot
  be converted to type <byte[]>

Closes gh-25480

Subject: [PATCH 1251/2315] Fix bug in StaticListableBeanFactory.isSingleton()

Prior to this commit, StaticListableBeanFactory.isSingleton() returned
false for singleton beans unless they were created by a FactoryBean.

StaticListableBeanFactory.isSingleton() now properly returns true for
all beans not created by a FactoryBean.

Closes gh-25522

Subject: [PATCH 1253/2315] Drop support for standalone "L" in CronExpression

This commit removes support for a standalone "L" in the
day-of-week of a cron expression, which used a locale-dependent
API to determine what the last day of the week is (Saturday or
Sunday ?).
Alternatively, we could have implement this in the exact way as Quartz
has done (i.e. treat the "L" like "SAT"), but we opted not to do that,
as having an explicit SAT or SUN is much clearer.

Subject: [PATCH 1258/2315] Support @RestControllerAdvice in Standalone MockMvc
 again

Since Spring Framework 5.2, @RestControllerAdvice registered with
MockMvc when using MockMvcBuilders.standaloneSetup() has no longer been
properly supported if annotation attributes were declared in the
@RestControllerAdvice annotation. Prior to 5.2, this was not an issue.

The cause for this regression is two-fold.

1. Commit 50c257794f7845829ac9ce78a102ef94e7e28a2e refactored
   DefaultListableBeanFactory so that findAnnotationOnBean() supports
   merged annotations; however, that commit did not refactor
   StaticListableBeanFactory#findAnnotationOnBean() to support merged
   annotations.

2. Commit 978adbdae749566fbf458f4f72847dfc0b5aabf7 refactored
   ControllerAdviceBean so that a merged @ControllerAdvice annotation
   is only looked up via ApplicationContext#findAnnotationOnBean().

The latter relies on the fact that findAnnotationOnBean() supports
merged annotations (e.g., @RestControllerAdvice as a merged instance of
@ControllerAdvice). Behind the scenes, MockMvcBuilders.standaloneSetup()
creates a StubWebApplicationContext which internally uses a
StubBeanFactory which extends StaticListableBeanFactory. Consequently,
since the implementation of findAnnotationOnBean() in
StaticListableBeanFactory was not updated to support merged annotations
like it was in DefaultListableBeanFactory, we only see this regression
with the standalone MockMvc support and not with MockMvc support for an
existing WebApplicationContext or with standard Spring applications
using an ApplicationContext that uses DefaultListableBeanFactory.

This commit fixes this regression by supporting merged annotations in
StaticListableBeanFactory#findAnnotationOnBean() as well.

Closes gh-25520

Subject: [PATCH 1286/2315] Assert preconditions for MergedAnnotations.from()
 factory methods

Prior to this commit, if null values were supplied for the
RepeatableContainers or AnnotationFilter arguments to `from()` factory
methods in MergedAnnotations, certain operations would eventually
result in a NullPointerException. This is to be expected; however, the
NullPointerException is often swallowed and only logged at INFO level
with an exception message similar to the following.

> Failed to introspect annotations on org.example.MyClass: NullPointerException

In such cases, the INFO log message is not helpful in diagnosing the
problem. Furthermore, since the exception is swallowed, the desired
operation (e.g., MergedAnnotations.stream(...)) simply returns no
results.

This commit improves the user experience by eagerly asserting non-null
preconditions for required arguments in MergedAnnotations.from()
factory methods.

Closes gh-25568

Subject: [PATCH 1301/2315] Update contentType property via
 MockHttpServletResponse::setCharacterEncoding()

Prior to this commit, MockHttpServletResponse's setCharacterEncoding()
method did not update the contentType property, which violates the
Servlet 2.4 Javadoc for getContentType() and setCharacterEncoding().

This commit addresses this issue; however, some existing tests may have
to be updated as a result of this change.

For example, note how some of the tests in this commit have been
refactored to use MediaType##isCompatibleWith() instead of asserting
exact matches for the value returned by MockHttpServletResponse's
getContentType() method.

Closes gh-25536

+Since Spring Framework 5.0, Spring comes with its own Commons Logging bridge implemented
+in the `spring-jcl` module. The implementation checks for the presence of the Log4j 2.x
+API and the SLF4J 1.7 API in the classpath and uses the first one of those found as the
+logging implementation, falling back to the Java platform's core logging facilities (also
+known as _JUL_ or `java.util.logging`) if neither Log4j 2.x nor SLF4J is available.
+
+Put Log4j 2.x or Logback (or another SLF4J provider) in your classpath, without any extra
+bridges, and let the framework auto-adapt to your choice. For further information see the
+https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#boot-features-logging[Spring
+Boot Logging Reference Documentation].
+
+[NOTE]
+====
+Spring's Commons Logging variant is only meant to be used for infrastructure logging
+purposes in the core framework and in extensions.
+
+For logging needs within application code, prefer direct use of Log4j 2.x, SLF4J, or JUL.
+====
+
+A `Log` implementation may be retrieved via `org.apache.commons.logging.LogFactory` as in
+the following example.

Subject: [PATCH 1319/2315] Introduce createContext() factory method in
 AbstractGenericContextLoader

Prior to this commit it was possible to configure the
DefaultListableBeanFactory used by the GenericApplicationContext
created by AbstractGenericContextLoader, but it was not possible to
completely replace the bean factory.

This commit introduces a new createContext() factory method in
AbstractGenericContextLoader which indirectly allows subclasses to
supply a custom DefaultListableBeanFactory implementation to the
GenericApplicationContext.

Subject: [PATCH 1324/2315] WebTestClient releases body on
 returnResult(Void.class)

The original behavior was to ignore the body which came with odd
warnings in the Javadoc and potential leaks that could be reported
from tests causing unnecessary concern.

This change causes the body to be released and effectively still
ignores it but minus the potential leaks.

See gh-19647

Subject: [PATCH 1325/2315] Add mechanism to expose mock server results

WebTestClient is an actual client and generally it's only possible
to assert the client response (i.e. what goes over HTTP). However,
in a mock server scenario technically we have access to the server
request and response and can make those available for further
assertions.

This will be helpful for the WebTestClient integration with MockMvc
where many more assertions can be performed on the server request
and response when needed.

See gh-19647

Subject: [PATCH 1326/2315] WebTestClient header assertion improvements

Provides parity with similar options in MockMvc:
 - compare header using a long value
 - compare header using a date/time value
 - dedicated method for "Location" header (redirect)
 - let Hamcrest assert a header even when missing

Subject: [PATCH 1331/2315] Fix regressions in SimpleThreadScope and
 SimpleTransactionScope

PR gh-25038 introduced regressions in SimpleThreadScope and
SimpleTransactionScope in Spring Framework 5.2.7. Specifically, if a
thread-scoped or transaction-scoped bean has a dependency on another
thread-scoped or transaction-scoped bean, respectively, a
ConcurrentModificationException will be thrown on Java 11 or higher.

The reason is that Java 11 introduced a check for concurrent
modification in java.util.HashMap's computeIfAbsent() implementation,
and such a modification can occur when a thread-scoped bean is being
created in order to satisfy a dependency of another thread-scoped bean
that is currently being created.

This commit fixes these regressions by switching from HashMap to
ConcurrentHashMap for the instance maps in SimpleThreadScope and
SimpleTransactionScope.

Closes gh-25618

Subject: [PATCH 1333/2315] Call StartupStep.end in finally block

Prior to this commit it was possible that a StartupStep was
started but never ended. This was the case when an exception
occured during bean initializing. To always call the method
regardless of the outcome, the call to StartupStep.end has
been moved to a finally block.

When an exception occurs the StartupStep is also enriched with
the exception class and message for diagnostic purposes.

See gh-22776

Subject: [PATCH 1348/2315] OrderedMessageSender throughput improvement

Before this change messages were sent serially across sessions but
ordering is important only within a session. This leads to head of
line blocking when a session is slow to send, and also enforcement of
send buffer size and time limits is precluded because it happens at
a lower level in the transport.

This change ensures messages are held up only if there is another
from the same session is being sent. This allows messages from each
session to flow independent of other.

See gh-25581

 == Setup
 
-To create a `WebTestClient` you must choose one of several server setup options.
-Effectively you're either configuring the WebFlux application to bind to or using
-a URL to connect to a running server.
+To set up a `WebTestClient` you need to choose a server setup to bind to. This can be one
+of several mock server setup choices or a connection to a live server.

-=== Spring MVC Test Framework
-
-The Spring MVC Test framework provides first class support for testing Spring MVC code
-with a fluent API that you can use with JUnit, TestNG, or any other testing framework. It
-is built on the {api-spring-framework}/mock/web/package-summary.html[Servlet API mock objects]
-from the `spring-test` module and, hence, does not use a running Servlet container. It
-uses the `DispatcherServlet` to provide full Spring MVC runtime behavior and provides
-support for loading actual Spring configuration with the TestContext framework in
-addition to a standalone mode, in which you can manually instantiate controllers and test
-them one at a time.
-
-Spring MVC Test also provides client-side support for testing code that uses the
-`RestTemplate`. Client-side tests mock the server responses and also do not use a running
-server.
-
-TIP: Spring Boot provides an option to write full, end-to-end integration tests that
-include a running server. If this is your goal, see the
-{doc-spring-boot}/html/spring-boot-features.html#boot-features-testing[Spring Boot Reference Guide].
-For more information on the differences between out-of-container and end-to-end
-integration tests, see <<spring-mvc-test-vs-end-to-end-integration-tests>>.

-==== Server-Side Tests
 
-You can write a plain unit test for a Spring MVC controller by using JUnit or TestNG. To
-do so, instantiate the controller, inject it with mocked or stubbed dependencies, and
-call its methods (passing `MockHttpServletRequest`, `MockHttpServletResponse`, and
-others, as necessary). However, when writing such a unit test, much remains untested: for
-example, request mappings, data binding, type conversion, validation, and much more.
-Furthermore, other controller methods such as `@InitBinder`, `@ModelAttribute`, and
-`@ExceptionHandler` may also be invoked as part of the request processing lifecycle.
+[[spring-mvc-test-framework]]
+=== MockMvc
 
-The goal of Spring MVC Test is to provide an effective way to test controllers by
-performing requests and generating responses through the actual `DispatcherServlet`.
+The Spring MVC Test framework, also known as MockMvc, provides support for testing Spring
+MVC applications. It performs full Spring MVC request handling but via mock request and
+response objects instead of a running server.
 
-Spring MVC Test builds on the familiar <<mock-objects-servlet, "`mock`" implementations of
-the Servlet API>> available in the `spring-test` module. This allows performing requests
-and generating responses without the need for running in a Servlet container. For the
-most part, everything should work as it does at runtime with a few notable exceptions, as
-explained in <<spring-mvc-test-vs-end-to-end-integration-tests>>. The following JUnit
-Jupiter-based example uses Spring MVC Test:
+MockMvc can be used on its own to perform requests and verify responses. It can also be
+used through the <<webtestclient>> where MockMvc is plugged in as the server to handle
+requests with. The advantage of `WebTestClient` is the option to work with higher level
+objects instead of raw data as well as the ability to switch to full, end-to-end HTTP
+tests against a live server and use the same test API.

-		MockMvc mockMvc;
+You can write plain unit tests for Spring MVC by instantiating a controller, injecting it

-		@BeforeEach

-			this.mockMvc = MockMvcBuilders.webAppContextSetup(wac).build();
-		}
+The Spring MVC Test framework, also known as `MockMvc`, aims to provide more complete
+testing for Spring MVC controllers without a running server. It does that by invoking
+the `DispacherServlet` and passing
+<<mock-objects-servlet, "`mock`" implementations of the Servlet API>> from the
+`spring-test` module which replicates the full Spring MVC request handling without
+a running server.

+When using MockMvc through the <<webtestclient>> you do not need static imports.
+The `WebTestClient` provides a fluent API without static imports.
 
-The `MockMvc` instance is used to perform a `GET` request to `/accounts/1` and verify

-https://spring.io/tools[Spring Tools for Eclipse], be sure to add them as "`favorite static members`" in

 [[spring-mvc-test-server-setup-options]]
 ===== Setup Choices
 
-You have two main options for creating an instance of `MockMvc`. The first is to load
-Spring MVC configuration through the TestContext framework, which loads the Spring
-configuration and injects a `WebApplicationContext` into the test to use to build a
-`MockMvc` instance. The following example shows how to do so:
+MockMvc can be setup in one of two ways. One is to point directly to the controllers you
+want to test and programmatically configure Spring MVC infrastructure. The second is to

Subject: [PATCH 1392/2315] Polish StartupStep "tags" method

Renaming the `tags` method to `getTags` for overall consistency, and
fixing the Javadoc to mention that this returns an immutable collection.

Closes gh-25678

Subject: [PATCH 1393/2315] Respect context path in WebMvc.fn & WebFlux.fn

This commit makes several changes in both WebMvc.fn as well as
WebFlux.fn.

 - ServerRequest now exposes a RequestPath through requestPath(), and
   pathContainer() has been deprecated.

 - The PathPredicate and PathResourceLookupFunction now respects this
   RequestPath's pathInApplication() in their path-related
   functionality.

 - When nesting, the PathPredicate now appends the matched part of the
   path to the current context path, instead of removing the matched
   part (which was done previously). This has the same result: the
   matched part is gone, but now the full path stays the same.

Closes gh-25270

Subject: [PATCH 1394/2315] Retry SQLErrorCodesFactory retrieval if
 DatabaseMetaData access failed

Includes deprecation of JdbcUtils.extractDatabaseMetaData(DataSource, String) in favor of the now generified version of extractDatabaseMetaData(DataSource, DatabaseMetaDataCallback).

Closes gh-25681

Subject: [PATCH 1403/2315] Early configuration of ApplicationStartup on
 BeanFactory

Prior to this commit, the `GenericApplicationContext` configured the
`AppliationStartup` on the `BeanFactory` only right before refreshing it.
Delaying this has no purpose and we should instead configure it as soon
as possible by overriding the setter method.

Closes gh-25718

Subject: [PATCH 1414/2315] Shared read-only instances of UrlPathHelper

UrlPathHelper is often created and used without customizations or with
the same customizations. This commit introduces re-usable, instances.
Effectively a backport of commit 23233c.

Subject: [PATCH 1426/2315] Improve MIME type subtype suffix handling

Prior to this commit, the subtype suffix of a MIME type (see RFC 6839)
was not properly taken into account when checking compatibility between
MIME types.

For example, `"application/*"` was not considered as compatible with
`"application/vnd.io.spring+json"`.

This commit adds a new `MimeType#getSubtypeSuffix()` method to easily
extract the subtype suffix information. This method is then reused in
the `isCompatibleWith` implementation to better handle these cases.

Fixes gh-25350

Subject: [PATCH 1437/2315] Publish documentation under reference/html folder

This is done:
 - For consistency with other Spring projects
 - Because it is probably a better option to use reference instead of
   spring-framework-reference (spring-framework is already present in
   the URL)
 - To improve PDF documentation discoverability

As a consequence:
 - spring-framework-reference HTML documentation is now published
   under reference/html
 - spring-framework-reference/pdf PDF documentation is now published
   under reference/pdf

The following permanent redirect should be created before Spring
Framework 5.3.0 release:
 - current/spring-framework-reference/pdf/* to current/reference/pdf/*
 - current/spring-framework-reference/* to current/reference/html/*

Subject: [PATCH 1445/2315] Wrap exceptions in WebClient

This commit makes sure that exceptions emitted by WebClient are wrapped
by WebClientExceptions:

- Exceptions emitted by the ClientHttpConnector are wrapped in a new
  WebClientRequestException.

- Exceptions emitted after a response is received are wrapped in a
  WebClientResponseException

+=== Kotlin multiplatform serialization
+
+As of Spring Framework 5.3, https://github.com/Kotlin/kotlinx.serialization[Kotlin multiplatform serialization] is
+supported in Spring MVC. The builtin support currently only targets JSON format.
+
+To enable it, follow https://github.com/Kotlin/kotlinx.serialization#setup[those instructions] and make sure neither
+Jackson, GSON or JSONB are in the classpath.
+
+NOTE: For a typical Spring Boot web application, that can be achieved by excluding `spring-boot-starter-json` dependency.
+
+If you need Jackson, GSON or JSONB for other purposes, you can keep them on the classpath and
+<<web#mvc-config-message-converters, configure message converters>> to remove `MappingJackson2HttpMessageConverter` and add
+`KotlinSerializationJsonHttpMessageConverter`.
+
+
 == Coroutines

Subject: [PATCH 1461/2315] Update AbstractDataBufferAllocatingTests

We are passing custom values to the constructor of PooledByteBufAllocator in
tests in order to turn of caching. This is based on:
https://github.com/netty/netty/issues/5275#issuecomment-220547057

Netty 4.1.52 has significant changes in PooledByteBufAllocator:
https://github.com/netty/netty/pull/10267

After the changes, our current value for maxOrder=2, which results in
chunkSize=16K, causes an assert failure in PoolChunk where the runSize
exceeds the chunkSize.

Subject: [PATCH 1474/2315] Remove unnecessary folders and files from PDF
 reference documentation

Prior to this commit, the asciidoctor Gradle task was configured to
generate both the HTML5 and PDF backends. Unfortunately, this resulted
in resources such as HTML, JavaScript, CSS, and images being published
alongside the generated PDF documents.

This commit addresses this issue by introducing the use of a dedicated
asciidoctorPdf Gradle task. The existing asciidoctor Gradle task has
been modified to only generate HTML5 output. Both of these tasks now
share common configuration supplied by the updated asciidoctorj Gradle
task.

In addition, the asciidoctor task now depends on the asciidoctorPdf
task. Thus, invoking `./gradlew asciidoctor` will still generate both
the HTML5 and PDF outputs; whereas, `./gradlew asciidoctorPdf` will
generate only the PDF outputs. We may later decide to rework the tasks
to introduce a dedicated asciidoctorHtml task so that we can generate
the HTML outputs without having to generate the PDF outputs (which are
more time consuming).

Subject: [PATCH 1479/2315] Do not generate reference docs for include-files

Prior to this commit, the Asciidoctor Gradle tasks generated top-level
HTML and PDF documents for AsciiDoc files that are included in other
top-level documents. This causes slower builds and results in each
include-file being published twice:

1) inline in the including document (as intended)
2) as a top-level document but missing surrounding context (unintended)

The reason these include-files are generated as top-level documents is
that the asciidoctor and asciidoctorPdf Gradle tasks are configured to
use '*.adoc' as the input source files.

This commit addresses this issue by moving the following include-files
to new subdirectories. Locating the include-files in the subdirectories
causes them to be ignored in the '*.adoc' pattern used to identify
input source files.

- data-access-appendix.adoc -> data-access/data-access-appendix.adoc
- integration-appendix.adoc -> integration/integration-appendix.adoc
- testing-webtestclient.adoc -> testing/testing-webtestclient.adoc

Closes gh-25783

Subject: [PATCH 1480/2315] Remove unnecessary folders and files from PDF
 reference documentation

Prior to this commit, the asciidoctor Gradle task was configured to
generate both the HTML5 and PDF backends. Unfortunately, this resulted
in resources such as HTML, JavaScript, CSS, and images being published
alongside the generated PDF documents.

This commit addresses this issue by introducing the use of a dedicated
asciidoctorPdf Gradle task. The existing asciidoctor Gradle task has
been modified to only generate HTML5 output. Both of these tasks now
share common configuration supplied by the updated asciidoctorj Gradle
task.

In addition, the asciidoctor task now depends on the asciidoctorPdf
task. Thus, invoking `./gradlew asciidoctor` will still generate both
the HTML5 and PDF outputs; whereas, `./gradlew asciidoctorPdf` will
generate only the PDF outputs. We may later decide to rework the tasks
to introduce a dedicated asciidoctorHtml task so that we can generate
the HTML outputs without having to generate the PDF outputs (which are
more time consuming).

Subject: [PATCH 1481/2315] Do not generate reference docs for include-files

Prior to this commit, the Asciidoctor Gradle tasks generated top-level
HTML and PDF documents for AsciiDoc files that are included in other
top-level documents. This causes slower builds and results in each
include-file being published twice:

1) inline in the including document (as intended)
2) as a top-level document but missing surrounding context (unintended)

The reason these include-files are generated as top-level documents is
that the asciidoctor and asciidoctorPdf Gradle tasks are configured to
use '*.adoc' as the input source files.

This commit addresses this issue by moving the following include-files
to new subdirectories. Locating the include-files in the subdirectories
causes them to be ignored in the '*.adoc' pattern used to identify
input source files.

- data-access-appendix.adoc -> data-access/data-access-appendix.adoc
- integration-appendix.adoc -> integration/integration-appendix.adoc
- testing-webtestclient.adoc -> testing/testing-webtestclient.adoc

Closes gh-25783

Subject: [PATCH 1484/2315] Fix missing reference doc from docs archive

Prior to this commit, the `docsZip` task would not reference the new
output locations for the `asciidoctor` and `asciidoctorPdf` tasks.
This results with missing reference docs in the docs zip.

This commit updates the input locations of the Zip task to include the

Subject: [PATCH 1489/2315] Revert use of Map::computeIfAbsent in thread and tx
 scopes

Issues gh-25038 and gh-25618 collectively introduced a regression for
thread-scoped and transaction-scoped beans.

For example, given a thread-scoped bean X that depends on another
thread-scoped bean Y, if the names of the beans (when used as map keys)
end up in the same bucket within a ConcurrentHashMap AND an attempt is
made to retrieve bean X from the ApplicationContext prior to retrieving
bean Y, then the use of Map::computeIfAbsent in SimpleThreadScope
results in recursive access to the same internal bucket in the map.

On Java 8, that scenario simply hangs. On Java 9 and higher,
ConcurrentHashMap throws an IllegalStateException pointing out that a
"Recursive update" was attempted.

In light of these findings, we are reverting the changes made to
SimpleThreadScope and SimpleTransactionScope in commits 50a4fdac6e and
148dc95eb1.

Closes gh-25801

Subject: [PATCH 1501/2315] Requalify tests as LONG_RUNNING

Prior to this commit, some tests would belong to the PERFORMANCE
`TestGroup`, while they were not testing for performance but rather
performing functional tests that involve long running operations or
timeouts.

This commit moves those tests to the LONG_RUNNING `TestGroup`.

See gh-24830

From e33e7d7681dc73560071bca4e9e62208cb9a1f27 Mon Sep 17 00:00:00 2001
From: Brian Clozel <bclozel@vmware.com>

Subject: [PATCH 1503/2315] Remove TestGroup.PERFORMANCE

Now that there's a new JMH infrastructure for benchmarks and that
performance tests have been rewritten to use it, we should remove the
`PERFORMANCE` `TestGroup` to avoid introducing such tests in the future.

Closes gh-24830

Subject: [PATCH 1506/2315] Deprecate LiveBeansView

This commit deprecates LiveBeansView and related classes in order to allow
a future removal in order to increase the separation of concerns between
Spring Framework and Spring Boot, and the consistency between JVM
and native.

Closes gh-25820

- * <p><strong>NOTE:</strong> When using a {@link ClientResponse}
- * through the {@code WebClient}
- * {@link WebClient.RequestHeadersSpec#exchange() exchange()} method,
- * you have to make sure that the body is consumed or released by using
- * one of the following methods:
- * <ul>
- * <li>{@link #body(BodyExtractor)}</li>
- * <li>{@link #bodyToMono(Class)} or
- *     {@link #bodyToMono(ParameterizedTypeReference)}</li>

-*  <li>{@link #toBodilessEntity()}</li>
- * <li>{@link #releaseBody()}</li>
- * </ul>
- * You can also use {@code bodyToMono(Void.class)} if no response content is
- * expected. However keep in mind the connection will be closed, instead of
- * being placed back in the pool, if any content does arrive. This is in
- * contrast to {@link #releaseBody()} which does consume the full body and
- * releases any content received.

Subject: [PATCH 1510/2315] Remove use of WebClient#exchange from WebTestClient

The exchange() method is now deprecated because it is not safe for
general use but that doesn't apply to the WebTestClient because it
exposes a different higher level API for response handling that
ensures the response is consumed. Nevertheless WebTestClient cannot
call WebClient.exchange() any more.

To fix this WebTestClient no longer delegates to WebClient and thus
gains direct access to the underlying ExchangeFunction. This is
not a big deal because WebClient and WebTestClient do the same
only when it comes to gathering builder options and request input.

See gh-25751

-[CAUTION]
-====
-Unlike `retrieve()`, when using `exchange()`, it is the responsibility of the application
-to consume any response content regardless of the scenario (success, error, unexpected
-data, etc). Not doing so can cause a memory leak. The Javadoc for `ClientResponse` lists
-all the available options for consuming the body. Generally prefer using `retrieve()`
-unless you have a good reason for using `exchange()` which does allow to check the
-response status and headers before deciding how to or if to consume the response.

Subject: [PATCH 1518/2315] Remove inefficiency in HttpStatus.series()

Prior to this commit, the Series value for an HttpStatus was always
evaluated which resulted in an allocation of a Series array by invoking
Series.values() which makes a defensive copy.

This commit addresses this issue by hardcoding the corresponding Series
within the HttpStatus constructor, thereby avoiding any unnecessary
computations. In addition, a unit test has been added to verify that
all HttpStatus enum constants have a properly configured Series.

Closes gh-22366

 /**
- * A base for classes providing strongly typed getters and setters as well as
- * behavior around specific categories of headers (e.g. STOMP headers).
- * Supports creating new headers, modifying existing headers (when still mutable),
- * or copying and modifying existing headers.
- *
- * <p>The method {@link #getMessageHeaders()} provides access to the underlying,
- * fully-prepared {@link MessageHeaders} that can then be used as-is (i.e.
- * without copying) to create a single message as follows:
+ * Wrapper around {@link MessageHeaders} that provides extra features such as
+ * strongly typed accessors for specific headers, the ability to leave headers
+ * in a {@link Message} mutable, and the option to suppress automatic generation
+ * of {@link MessageHeaders#ID id} and {@link MessageHeaders#TIMESTAMP
+ * timesteamp} headers. Sub-classes such as {@link NativeMessageHeaderAccessor}
+ * and others provide support for managing processing vs external source headers
+ * as well as protocol specific headers.
  *
+ * <p>Below is a workflow to initialize headers via {@code MessageHeaderAccessor},
+ * or one of its sub-classes, then create a {@link Message}, and then re-obtain
+ * the accessor possibly from a different component:
  * <pre class="code">
+ * // Create a message with headers
  * MessageHeaderAccessor accessor = new MessageHeaderAccessor();
  * accessor.setHeader("foo", "bar");
- * Message message = MessageBuilder.createMessage("payload", accessor.getMessageHeaders());
- * </pre>
+ * MessageHeaders headers = accessor.getMessageHeaders();
+ * Message message = MessageBuilder.createMessage("payload", headers);
  *
- * <p>After the above, by default the {@code MessageHeaderAccessor} becomes
- * immutable. However it is possible to leave it mutable for further initialization
- * in the same thread, for example:
+ * // Later on
+ * MessageHeaderAccessor accessor = MessageHeaderAccessor.getAccessor(message);
+ * Assert.notNull(accessor, "No MessageHeaderAccessor");
+ * </pre>
  *
+ * <p>In order for the above to work, all participating components must use
+ * {@code MessageHeaders} to create, access, or modify headers, or otherwise
+ * {@link MessageHeaderAccessor#getAccessor(Message, Class)} will return null.
+ * Below is a workflow that shows how headers are created and left mutable,
+ * then modified possibly by a different component, and finally made immutable
+ * perhaps before the possibility of being accessed on a different thread:
  * <pre class="code">
+ * // Create a message with mutable headers
  * MessageHeaderAccessor accessor = new MessageHeaderAccessor();
  * accessor.setHeader("foo", "bar");
  * accessor.setLeaveMutable(true);
- * Message message = MessageBuilder.createMessage("payload", accessor.getMessageHeaders());
+ * MessageHeaders headers = accessor.getMessageHeaders();
+ * Message message = MessageBuilder.createMessage("payload", headers);
  *
- * // later on in the same thread...
+ * // Later on
+ * MessageHeaderAccessor accessor = MessageHeaderAccessor.getAccessor(message);
+ * if (accessor.isMutable()) {
+ *     // It's mutable, just change the headers
+ *     accessor.setHeader("bar", "baz");
+ * }
+ * else {
+ *     // It's not, so get a mutable copy, change and re-create
+ *     accessor = MessageHeaderAccessor.getMutableAccessor(message);
+ *     accessor.setHeader("bar", "baz");
+ *     accessor.setLeaveMutable(true); // leave mutable again or not?
+ *     message = MessageBuilder.createMessage(message.getPayload(), accessor);
+ * }
  *
+ * // Make the accessor immutable
  * MessageHeaderAccessor accessor = MessageHeaderAccessor.getAccessor(message);
- * accessor.setHeader("bar", "baz");
  * accessor.setImmutable();
  * </pre>
  *
- * <p>The method {@link #toMap()} returns a copy of the underlying headers. It can
- * be used to prepare multiple messages from the same {@code MessageHeaderAccessor}
- * instance:
- * <pre class="code">
- * MessageHeaderAccessor accessor = new MessageHeaderAccessor();
- * MessageBuilder builder = MessageBuilder.withPayload("payload").setHeaders(accessor);
- *
- * accessor.setHeader("foo", "bar1");
- * Message message1 = builder.build();
- *
- * accessor.setHeader("foo", "bar2");
- * Message message2 = builder.build();
- *
- * accessor.setHeader("foo", "bar3");
- * Message  message3 = builder.build();
- * </pre>
- *
- * <p>However note that with the above style, the header accessor is shared and
- * cannot be re-obtained later on. Alternatively it is also possible to create
- * one {@code MessageHeaderAccessor} per message:
- *
- * <pre class="code">
- * MessageHeaderAccessor accessor1 = new MessageHeaderAccessor();
- * accessor.set("foo", "bar1");
- * Message message1 = MessageBuilder.createMessage("payload", accessor1.getMessageHeaders());
- *
- * MessageHeaderAccessor accessor2 = new MessageHeaderAccessor();
- * accessor.set("foo", "bar2");
- * Message message2 = MessageBuilder.createMessage("payload", accessor2.getMessageHeaders());
- *
- * MessageHeaderAccessor accessor3 = new MessageHeaderAccessor();
- * accessor.set("foo", "bar3");
- * Message message3 = MessageBuilder.createMessage("payload", accessor3.getMessageHeaders());
- * </pre>
- *
- * <p>Note that the above examples aim to demonstrate the general idea of using
- * header accessors. The most likely usage however is through subclasses.

Subject: [PATCH 1528/2315] Add ServerResponse.async() in WebMvc.fn

This commit introduces a new async(Object) method in the WebMvc.fn,
taking a asynchronous response as argument in the form of a
CompletableFuture or Publisher. This allows for asynchronous setting
of headers and status (and not just body, which was already possible).

Closes gh-25828

Subject: [PATCH 1533/2315] Add no path HTTP method variants for route builder

This commit adds two overloaded methods for each HTTP method in the
WebFlux.fn and WebMvc.fn route builders: one method taking just a
handler function, the other a request predicate and handler function.

After this commit, it is no longer required to provide a String path,
which is particularly useful when nesting routes, and the path would be
"".

Closes gh-25752

+You can resolve such issues by making Hibernate aware of the JTA transaction manager,
+to which it synchronizes (along with Spring). You have two options for doing this:
 
-* If, in your application context, you already directly obtain the JTA
-  `PlatformTransactionManager` object (presumably from JNDI through
-  `JndiObjectFactoryBean` or `<jee:jndi-lookup>`) and feed it, for example, to
-  Spring's `JtaTransactionManager`, the easiest way is to specify a reference to
-  the bean that defines this JTA `PlatformTransactionManager` instance as the value of the
-  `jtaTransactionManager` property for `LocalSessionFactoryBean.` Spring then makes the
-  object available to Hibernate.
-* More likely, you do not already have the JTA `PlatformTransactionManager` instance,
-  because Spring's `JtaTransactionManager` can find it itself. Thus, you need to
-  configure Hibernate to look up JTA `PlatformTransactionManager` directly. You do this
-  by configuring an application server-specific `TransactionManagerLookup` class in the
-  Hibernate configuration, as described in the Hibernate manual.
+* Pass your Spring `JtaTransactionManager` bean to your Hibernate setup. The easiest
+  way is a bean reference into the `jtaTransactionManager` property for your
+  `LocalSessionFactoryBean` bean (see <<transaction-strategies-hibernate>>).
+  Spring then makes the corresponding JTA strategies available to Hibernate.
+* You may also configure Hibernate's JTA-related properties explicitly, in particular
+  "hibernate.transaction.coordinator_class", "hibernate.connection.handling_mode"
+  and potentially "hibernate.transaction.jta.platform" in your "hibernateProperties"
+  on `LocalSessionFactoryBean` (see Hibernate's manual for details on those properties).

Subject: [PATCH 1538/2315] Revert errorhandler order in RouterFunctionBuilder

Prior to this commit, error handlers in the WebMvc.fn and WebFlux.fn
router function builders had to be registered in an unintuitive, reverse
order, due to the filter chain composition model used.
This commit reverses the error handler order, so that more specific
error handlers can come before generic ones.

Closes gh-25541

Subject: [PATCH 1541/2315] Add option for ignoring last-modified for static
 resources

Prior to this commit, the resource handler serving static resources for
Spring MVC and Spring WebFlux would always look at the
`Resource#lastModified` information, derive the `"Last-Modified"` HTTP
response header and support HTTP conditional requests with that
information.

In some cases, builds or packaging tools choose to set this last
modification date to a static date in the past. This allows tools to
have reproducible builds or to leverage caching given the static
resources content didn't change.

This can lead to problems where this static date (e.g. "1980-01-01") is
used literally in HTTP responses and will make the HTTP caching
mechanism counter-productive: the content of the resources changed, but
the application insists on saying it didn't change since the 80s...

This commit adds a new configuration option to disable this support -
there is no way to automatically discard those dates: there is no
standard for that and many don't use he "EPOCH 0 date" as it can lead to
compatibility issues with different OSes.

Closes gh-25845

Subject: [PATCH 1545/2315] Revert workaround in Jetty connector

The workaround was removed in the 5.3 milestone phase and in master
only because the referenced Jetty issue is marked fixed. However,
what we need to replace it with should be a little more involved
and also it's not entirely clear if the fixes in Jetty aligns with
our release and retain semantics so that needs to be investigated
more thoroughly.

Subject: [PATCH 1547/2315] Add kotlinx.serialization JSON support to Spring
 WebFlux

Flow decoding is not supported yet since it depends on
kotlin/kotlinx.serialization#1073, but it will be
enabled when this issue will be fixed.

Closes gh-25771

Subject: [PATCH 1559/2315] Support suspending handler methods in Spring MVC

This commit adds support for Kotlin Coroutines suspending functions to
Spring MVC, by converting those to a Mono that can then be handled by
the asynchronous request processing feature.

It also optimizes Coroutines detection with the introduction of an
optimized KotlinDetector.isSuspendingFunction() method that does not
require kotlin-reflect.

Closes gh-23611

Subject: [PATCH 1567/2315] Discover test config on enclosing classes for
 nested test classes

Prior to this commit (and since Spring Framework 5.0), Spring's
integration with JUnit Jupiter supported detection of test
configuration (e.g., @ContextConfiguration, etc.) on @Nested classes.
However, if a @Nested class did not declare its own test configuration,
Spring would not find the configuration from the enclosing class. This
is in contrast to Spring's support for automatic inheritance of test
configuration from superclasses. The only workaround was to
copy-n-paste the entire annotation configuration from enclosing classes
to nested tests classes, which is cumbersome and error prone.

This commit introduces a new @NestedTestConfiguration annotation that
allows one to choose the EnclosingConfiguration mode that Spring should
use when searching for test configuration on a @Nested test class.
Currently, the options are INHERIT or OVERRIDE, where the current
default is OVERRIDE. Note, however, that the default mode will be
changed to INHERIT in a subsequent commit. In addition, support will be
added to configure the global default mode via the SpringProperties
mechanism in order to allow development teams to revert to the behavior
prior to Spring Framework 5.3.

As of this commit, inheritance of the following annotations is honored
when the EnclosingConfiguration mode is INHERIT.

- @ContextConfiguration / @ContextHierarchy
- @ActiveProfiles
- @TestPropertySource / @TestPropertySources
- @WebAppConfiguration
- @TestConstructor
- @BootstrapWith
- @TestExecutionListeners
- @DirtiesContext
- @Transactional
- @Rollback / @Commit

This commit does NOT include support for inheriting the following
annotations on enclosing classes.

- @Sql / @SqlConfig / @SqlGroup

In order to implement this feature, the search algorithms in
MetaAnnotationUtils (and various other spring-test internals) have been
enhanced to detect when annotations should be looked up on enclosing
classes. Other parts of the ecosystem may find the new
searchEnclosingClass() method in MetaAnnotationUtils useful to provide
similar support.

As a side effect of the changes in this commit, validation of user
configuration in repeated @TestPropertySource declarations has been
removed, but this may be reintroduced at a later date.

Closes gh-19930

+ * {@code @NestedTestConfiguration} is a type-level annotation that is used to

+ *
+ * <p>If {@code @NestedTestConfiguration} is not <em>present</em> or
+ * <em>meta-present</em> on a test class, configuration from the test class will
+ * not propagate to inner test classes (see {@link EnclosingConfiguration#OVERRIDE}).
+ * Consequently, inner test classes will have to declare their own Spring test
+ * configuration annotations. If you wish for an inner test class to inherit
+ * configuration from its enclosing class, annotate either the inner test class
+ * or the enclosing class with
+ * {@code @NestedTestConfiguration(EnclosingConfiguration.INHERIT)}. Note that
+ * a {@code @NestedTestConfiguration(...)} declaration is inherited within the
+ * superclass hierarchy as well as within the enclosing class hierarchy. Thus,
+ * there is no need to redeclare the annotation unless you wish to switch the
+ * mode.
+ *
+ * <p>This annotation may be used as a <em>meta-annotation</em> to create custom
+ * <em>composed annotations</em>.
+ *
+ * <p>As of Spring Framework 5.3, the use of this annotation typically only makes
+ * sense in conjunction with {@link org.junit.jupiter.api.Nested @Nested} test
+ * classes in JUnit Jupiter.

Subject: [PATCH 1583/2315] Make default @NestedTestConfiguration mode
 configurable

Prior to this commit, the EnclosingConfiguration mode used in
conjunction with @NestedTestConfiguration defaulted to INHERIT.

In other to allow development teams to change the default to OVERRIDE
(e.g., for compatibility with Spring Framework 5.0 through 5.2), this
commit introduces support for changing the default EnclosingConfiguration
mode globally via a JVM system property or via the SpringProperties
mechanism.

For example, the default may be changed to
EnclosingConfiguration.OVERRIDE by supplying the following JVM system
property via the command line.

-Dspring.test.enclosing.configuration=override

Subject: [PATCH 1593/2315] Upgrade to Coroutines 1.4.0-M1 and use
 awaitSingle()

This commit raises the minimum Coroutines version supported
to 1.4.0-M1 and above, and changes usages of awaitFirst() or
awaitFirstOrNull() to awaitSingle() or awaitSingleOrNull()
to fix gh-25007.

Closes gh-25914
Closes gh-25007

Subject: [PATCH 1595/2315] Support Propagation.NEVER for disabling
 test-managed transactions

Prior to this commit only Propagation.NOT_SUPPORTED was supported for
disabling test-managed transactions via the `propagation` attribute of
`@Transactional`.

This commit allows users to specify Propagation.NOT_SUPPORTED or
Propagation.NEVER to disable test-managed transactions.

Closes gh-25909

+===== `@NestedTestConfiguration`
+
+`@NestedTestConfiguration` is a type-level annotation that is used to configure how
+Spring test configuration annotations are processed within enclosing class hierarchies
+for inner test classes.
+
+If `@NestedTestConfiguration` is not present or meta-present on a test class, in its
+super type hierarchy, or in its enclosing class hierarchy, the default _enclosing
+configuration inheritance mode_ will be used. See the tip below for details on how to
+change the default mode.
+
+.Changing the default enclosing configuration inheritance mode
+[TIP]
+=====
+The default _enclosing configuration inheritance mode_ is `INHERIT`, but it can be
+changed by setting the `spring.test.enclosing.configuration` JVM system property to
+`OVERRIDE`. Alternatively, the default mode may be set via the `SpringProperties`
+mechanism.

+NOTE: The use of `@NestedTestConfiguration` typically only makes sense in conjunction

+frameworks with support for Spring and nested test classes that make use of this
+annotation.

+[[testcontext-junit-jupiter-nested-test-configuration]]
+===== `@Nested` test class configuration
+
+The _Spring TestContext Framework_ has supported the use of test-related annotations on
+`@Nested` test classes in JUnit Jupiter since Spring Framework 5.0; however, until Spring
+Framework 5.3 class-level test configuration annotations were not _inherited_ from
+enclosing classes like they are from superclasses.
+
+Spring Framework 5.3 introduces first-class support for inheriting test class
+configuration from enclosing classes, and such configuration will be inherited by
+default. To change from the default `INHERIT` mode to `OVERRIDE` mode, you may annotate
+an individual `@Nested` test class with
+`@NestedTestConfiguration(EnclosingConfiguration.OVERRIDE)`. An explicit
+`@NestedTestConfiguration` declaration will apply to the annotated test class as well as
+any of its subclasses and nested classes. Thus, you may annotate a top-level test class
+with `@NestedTestConfiguration`, and that will apply to all of its nested test classes
+recursively.
+
+In order to allow development teams to change the default to `OVERRIDE` – for example,
+for compatibility with Spring Framework 5.0 through 5.2 – the default mode can be changed
+globally via a JVM system property or a `spring.properties` file in the root of the
+classpath. See the <<integration-testing-annotations-nestedtestconfiguration, "Changing
+the default enclosing configuration inheritance mode">> note for details.
+
+Although the following "Hello World" example is very simplistic, it shows how to declare
+common configuration on a top-level class that is inherited by its `@Nested` test
+classes. In this particular example, only the `TestConfig` configuration class is
+inherited. Each nested test class provides its own set of active profiles, resulting in a
+distinct `ApplicationContext` for each nested test class (see
+<<testcontext-ctx-management-caching>> for details). Consult the list of
+<<integration-testing-annotations-nestedtestconfiguration, supported annotations>> to see
+which annotations can be inherited in `@Nested` test classes.

Subject: [PATCH 1609/2315] Fix race issue and improve
 readAsynchronousFileChannel

Before this commit, ReadCompletionHandler delayed closing the channel
to allow an ongoing read to complete/fail so we can get a hold of the
associated DataBuffer and release it. This can be problematic since the
read take time to complete but even more importantly there was a race
condition where we didn't check if we've been disposed concurrently
while releasing the read flag.

This commit removes the delay and closes the channel immediately from
cancel() and that should in turn fail any ongoing read operation,
according to AsynchronousChannel, and the DataBuffer is released.

Further improvements include:
- combining the "reading" and "disposed" AtomicBoolean's into a
single "state" AtomicReference.
- an optimistic check to remain in READING mode and avoid state
switches when there is demand to continue reading.

Closes gh-25831

Subject: [PATCH 1627/2315] WebSocketTransportRegistration: javadoc typo

The documentation written for the method WebSocketTransportRegistration.setSendTimeLimit(int timeLimit) mentions that, if no time limit is specified, a default value of 10 seconds is used; however, later on the exact default value employed is incorrectly typed as 10 * 10000 ms, which would result in 100 seconds instead.
The javadoc has been updated in order to show the correct value in milliseconds (10 * 1000).

Subject: [PATCH 1628/2315] Optimize Jackson resource management in codecs

Prior to this commit, references to `JsonGenerator` and
`ByteArrayBuilder` were not closed/released within codecs calls.
This prevents Jackson from reusing more efficiently shared memory
resources.

This commit properly closes/releases Jackson resources in Spring MVC,
Spring WebFlux and Spring Messaging codecs.
A benchmark on WebFlux codecs (in both single value/streaming mode)
shows significant throughput and allocation improvements for small
payloads.

Closes gh-25910

Subject: [PATCH 1634/2315] Discover @Sql annotations on enclosing class for
 nested test class

This commit introduces support for discovering @Sql, @SqlGroup,
@SqlConfig, and @SqlMergeMode on enclosing classes for @Nested test
classes in JUnit Jupiter.

Closes gh-25913

Subject: [PATCH 1636/2315] Refactor StringDecoder

Simplify and optimize the processing of the input stream.

The existing implementation was using bufferUntil and creating a List
for every line along with an EndFrameBuffer inserted for the
bufferUntil predicate. So the larger the input buffer and the more
lines it contained, the greater the overhead.

The new implementation avoids bufferUntil for all lines and
instead uses concatMapIterable to aggregate the lines from a buffer
into a single list. So the larger the input buffer and the more
lines it contains, the better the throughput. The only buffering
used then is for partial chunks and those are accumulated in a list.

See gh-25915

Subject: [PATCH 1643/2315] Refactor DataBufferUtils Matcher implementation

The existing implementation was exposed to very poor performance when matching
with multiple delimiters against a large buffer with many delimiters. In that
case all matchers are invoked many times (as many as the number of delimiters)
even though some of them found no match at all on the first pass.

The revised implementation uses a single index and advances all matchers
together, checking one byte a time, and not letting any one of them search to
the end of the entire buffer on a single pass.

Closes gh-25915

Subject: [PATCH 1644/2315] Introduce TestContextAnnotationUtils to avoid
 package cycles

This commit introduces TestContextAnnotationUtils as a replacement for
MetaAnnotationUtils, with dedicated support for honoring the new
@NestedTestConfiguration annotation and related annotation search
semantics.

MetaAnnotationUtils has been reverted to its previous scope and is now
deprecated.

See gh-19930

This commit makes TransactionInterceptor and TransactionAspectSupport
Coroutines aware, adapting Reactive transaction support to Coroutines.

Suspending functions returning a Flow are handled like Flux, for other
return types, they are handled like Mono.

Closes gh-23575

Subject: [PATCH 1669/2315] Avoid cache miss for @ActiveProfiles w/ same
 profiles but different order

Prior to this commit, two @ActiveProfiles declarations with the same
profiles but different order resulted in an identical, duplicate
ApplicationContext in the context cache in the Spring TestContext
Framework.

This commit uses a TreeSet to ensure that registered active profiles
are both unique and sorted, thereby avoiding cache misses for
semantically identical active profiles configuration on different test
classes.

Closes gh-25973

Subject: [PATCH 1672/2315] Fix JUnit 4 to AssertJ migration bugs

The migration from JUnit 4 assertions to AssertJ assertions resulted in
several unnecessary casts from int to long that actually cause
assertions to pass when they should otherwise fail.

This commit fixes all such bugs for the pattern `.isNotEqualTo((long)`.

Subject: [PATCH 1674/2315] Ignore duplicate config metadata for cache key in
 TestContext framework

Prior to this commit, if a developer accidentally copied and pasted the
same @ContextConfiguration or @TestPropertySource declaration from a
test class to one of its subclasses or nested test classes, the Spring
TestContext Framework (TCF) would merge the inherited configuration
with the local configuration, resulting in different sets of
configuration metadata which in turn resulted in a different
ApplicationContext instance being loaded for the test classes. This
behavior led to unnecessary creation of identical application contexts
in the context cache for the TCF stored under different keys.

This commit ignores duplicate configuration metadata when generating
the ApplicationContext cache key (i.e., MergedContextConfiguration) in
the TCF. This is performed for the following annotations.

- @ContextConfiguration
- @ActiveProfiles (support already existed prior to this commit)
- @TestPropertySource

Specifically, if @ContextConfiguration or @TestPropertySource is
declared on a test class and its subclass or nested test class with the
exact same attributes, only one instance of the annotation will be used
to generate the cache key for the resulting ApplicationContext. The
exception to this rule is an "empty" annotation declaration. An empty
@ContextConfiguration or @TestPropertySource declaration signals that
Spring (or a third-party SmartContextLoader) should detect default
configuration specific to the annotated class. Thus, multiple empty
@ContextConfiguration or @TestPropertySource declarations within a test
class hierarchy are not considered to be duplicate configuration and
are therefore not ignored.

Since @TestPropertySource is a @Repeatable annotation, the same
duplicate configuration detection logic is applied for multiple
@TestPropertySource declarations on a single test class or test
interface.

In addition, this commit reinstates validation of the rules for
repeated @TestPropertySource annotations that was removed when support
for @NestedTestConfiguration was introduced.

Closes gh-25800

Subject: [PATCH 1678/2315] Support multiple matchers in MockMvc Kotlin DSL

Previous incarnation of MockMvc Kotlin DSL tried to reuse directly
Java APIs like ModelResultMatchers or StatusResultMatchers, but
when using multiple matchers in DSL blocks like model { } or
status { }, only the last statement was taken in account which
was very confusing.

This refactoring provides dedicated Kotlin DSLs for matchers.

The main API breaking changes is that functions like isOk() need to be
invoked with the parenthesis, isOk is not supported anymore (on purpose).

Closes gh-24103

Subject: [PATCH 1709/2315] Preserve registration order in @ActiveProfiles

With this commit, bean definition profiles declared via @ActiveProfiles
are once again stored in registration order, in order to support use
cases in Spring Boot and other frameworks that depend on the
registration order.

This effectively reverts the changes made in conjunction with gh-25973.

Subject: [PATCH 1715/2315] Use TYPE_HIERARCHY strategy in
 AnnoDescr.findAllLocalMergedAnnotations()

Prior to this commit, the findAllLocalMergedAnnotations() method in
AnnotationDescriptor altered between the use of TYPE_HIERARCHY and
TYPE_HIERARCHY_AND_ENCLOSING_CLASSES for the SearchStrategy, depending
on @NestedTestConfiguration semantics; however, when searching for
"local" annotations, there is no need to search the enclosing class
hierarchy since AnnotationDescriptor#next() handles that use case.

This commit therefore switches to using only the TYPE_HIERARCHY
strategy.

This commit also discontinues the use of
MergedAnnotationCollectors.toAnnotationSet() in order to avoid the
unnecessary creation of a temporary List when collecting synthesized
annotations in a LinkedHashSet.

Subject: [PATCH 1718/2315] Do not create intermediate list in
 MergedAnnotationCollectors.toAnnotationSet()

Prior to this commit, MergedAnnotationCollectors.toAnnotationSet()
created an intermediate ArrayList for storing the results prior to
creating a LinkedHashSet in the finishing step.

Since the creation of the intermediate list is unnecessary, this commit
simplifies the implementation of toAnnotationSet() by using the
Collector.of() factory method that does not accept a `finisher` argument.
The resulting Collector internally uses a `castingIdentity()` function
as the `finisher`.

Closes gh-26031

Subject: [PATCH 1722/2315] Add
 FullyQualifiedAnnotationBeanNameGenerator.INSTANCE

Adds a static INSTANCE to FullyQualifiedAnnotationBeanNameGenerator,
just like its parent class, AnnotationBeanNameGenerator, does.

The class doesn't have any state and overriding/hiding the INSTANCE of
the superclass, this prevents unintended use of a regular
AnnotationBeanNameGenerator through
FullyQualifiedAnnotationBeanNameGenerator.INSTANCE.

Subject: [PATCH 1760/2315] WebClient method to populate the Reactor Context

The alternative is to use a filter but this makes it a little easier
and also guarantees that it will be downstream from all filters
regardless of their order, and therefore the Context will be visible
to all of them.

Subject: [PATCH 1764/2315] Validate that test & lifecycle methods are not
 @Autowired

Prior to this commit, a developer may have accidentally annotated a
JUnit Jupiter test method or lifecycle method with @Autowired, and that
would have potentially resulted in an exception that was hard to
understand. This is because the Spring container considers any
@Autowired method to be a "configuration method" when autowiring the
test class instance. Consequently, such an @Autowired method would be
invoked twice: once by Spring while attempting to autowire the test
instance and another time by JUnit Jupiter when invoking the test or
lifecycle method. The autowiring invocation of the method often leads
to an exception, either because Spring cannot satisfy a dependency (such
as JUnit Jupiter's TestInfo) or because the body of the method fails due
to test setup that has not yet been invoked.

This commit introduces validation for @Autowired test and lifecycle
methods in the SpringExtension that will throw an IllegalStateException
if any @Autowired method in a test class is also annotated with any of
the following JUnit Jupiter annotations.

- @Test
- @TestFactory
- @TestTemplate
- @RepeatedTest
- @ParameterizedTest
- @BeforeAll
- @AfterAll
- @BeforeEach
- @AfterEach

Subject: [PATCH 1774/2315] Ensure test() conditions in JUnit TestKit match
 method names

Prior to this commit, the test("test") conditions used in
AutowiredConfigurationErrorsIntegrationTests inadvertently asserted
that the invoked test methods reside in an org.springframework.test
subpackage, which is always the case for any test method in the
`spring-test` module. In other words, "test" is always a substring of
"org.springframework.test...", which is not a meaningful assertion.

This commit ensures that the JUnit Platform Test Kit is asserting the
actual names of test methods.

+[[scheduling-cron-expression]]
+=== Cron Expressions
+
+All Spring cron expressions have to conform to the same format, whether you are using them in
+<<scheduling-annotation-support-scheduled,`@Scheduled` annotations>>,
+<<scheduling-task-namespace-scheduled-tasks,`task:scheduled-tasks` elements>>,
+or someplace else.
+A well-formed cron expression, such as `* * * * * *`, consists of six space-separated time and date
+fields, each with its own range of valid values:
+
+
+....
+ ┌───────────── second (0-59)
+ │ ┌───────────── minute (0 - 59)
+ │ │ ┌───────────── hour (0 - 23)
+ │ │ │ ┌───────────── day of the month (1 - 31)
+ │ │ │ │ ┌───────────── month (1 - 12) (or JAN-DEC)
+ │ │ │ │ │ ┌───────────── day of the week (0 - 7)
+ │ │ │ │ │ │          (0 or 7 is Sunday, or MON-SUN)
+ │ │ │ │ │ │
+ * * * * * *
+....
+
+There are some rules that apply:
+
+* A field may be an asterisk (`*`), which always stands for "`first-last`".
+For the day-of-the-month or day-of-the-week fields, a question mark (`?`) may be used instead of an
+asterisk.
+* Commas (`,`) are used to separate items of a list.
+* Two numbers separated with a hyphen (`-`) express a range of numbers.
+The specified range is inclusive.
+* Following a range (or `*`) with `/` specifies the interval of the number's value through the range.
+* English names can also be used for the day-of-month and day-of-week fields.
+Use the first three letters of the particular day or month (case does not matter).
+* The day-of-month and day-of-week fields can contain a `L` character, which has a different meaning
+** In the day-of-month field, `L` stands for _the last day of the month_.
+If followed by a negative offset (that is, `L-n`), it means _``n``th-to-last day of the month_.
+** In the day-of-week field, `L` stands for _the last day of the week_.
+If prefixed by a number or three-letter name (`dL` or `DDDL`), it means _the last day of week (`d`
+or `DDD`) in the month_.
+* The day-of-month field can be `nW`, which stands for _the nearest weekday to day of the month ``n``_.
+If `n` falls on Saturday, this yields the Friday before it.
+If `n` falls on Sunday, this yields the Monday after, which also happens if `n` is `1` and falls on
+a Saturday (that is: `1W` stands for _the first weekday of the month_).
+* If the day-of-month field is `LW`, it means _the last weekday of the month_.
+* The day-of-week field can be `d#n` (or `DDD#n`), which stands for _the ``n``th day of week `d`
+(or ``DDD``) in the month_.
+
+Here are some examples:
+
+|===
+| Cron Expression       | Meaning
+
+|`0 0 * * * *`          | top of every hour of every day
+|`*/10 * * * * *`       | every ten seconds
+| `0 0 8-10 * * *`      | 8, 9 and 10 o'clock of every day
+| `0 0 6,19 * * *`      | 6:00 AM and 7:00 PM every day
+| `0 0/30 8-10 * * *`   | 8:00, 8:30, 9:00, 9:30, 10:00 and 10:30 every day
+| `0 0 9-17 * * MON-FRI`| on the hour nine-to-five weekdays
+| `0 0 0 25 DEC ?`       | every Christmas Day at midnight
+| `0 0 0 L * *`         | last day of the month at midnight
+| `0 0 0 L-3 * *`       | third-to-last day of the month at midnight
+| `0 0 0 * * 5L`        | last Friday of the month at midnight
+| `0 0 0 * * THUL`      | last Thursday of the month at midnight
+| `0 0 0 1W * *`        | first weekday of the month at midnight
+| `0 0 0 LW * *`        | last weekday of the month at midnight
+| `0 0 0 ? * 5#2`       | the second Friday in the month at midnight
+| `0 0 0 ? * MON#1`     | the first Monday in the month at midnight
+|===
+
+==== Macros
+
+Expressions such as `0 0 * * * *` are hard for humans to parse and are, therefore, hard to fix in case of bugs.
+To improve readability, Spring supports the following macros, which represent commonly used sequences.
+You can use these macros instead of the six-digit value, thus: `@Scheduled(cron = "@hourly")`.
+
+|===
+|Macro                          | Meaning
+
+| `@yearly` (or `@annually`)    | once a year (`0 0 0 1 1 *`)
+| `@monthly`                    | once a month (`0 0 0 1 * *`)
+| `@weekly`                     | once a week (`0 0 0 * * 0`)
+| `@daily` (or `@midnight`)     | once a day (`0 0 0 * * *`), or
+| `@hourly`                     | once an hour, (`0 0 * * * *`)

Subject: [PATCH 1785/2315] Discover @DynamicPropertySource methods on
 enclosing test classes

gh-19930 introduced support for finding class-level test configuration
annotations on enclosing classes when using JUnit Jupiter @Nested test
classes, but support for @DynamicPropertySource methods got overlooked
since they are method-level annotations.

This commit addresses this shortcoming by introducing full support for
@NestedTestConfiguration semantics for @DynamicPropertySource methods
on enclosing classes.

Closes gh-26091

 NOTE: As of Spring Framework 5.3, Spring requires Hibernate ORM 5.2+ for Spring's
 `HibernateJpaVendorAdapter` as well as for a native Hibernate `SessionFactory` setup.
 Is is strongly recommended to go with Hibernate ORM 5.4 for a newly started application.
+For use with `HibernateJpaVendorAdapter`, Hibernate Search needs to be upgraded to 5.11.6.

Subject: [PATCH 1819/2315] Remove TODO from AbstractAspectJAdvice

Despite the code duplication, we will not delegate to
AopUtils.invokeJoinpointUsingReflection() from
AbstractAspectJAdvice.invokeAdviceMethodWithGivenArgs().

The rationale is that the exception message in
invokeAdviceMethodWithGivenArgs() provides additional context via the
pointcut expression, and we would lose that additional context if we
simply delegate to AopUtils.invokeJoinpointUsingReflection(). We could
introduce an overloaded variant of invokeJoinpointUsingReflection() that
accepts an additional argument to provide the additional context for the
exception message, but we don't think that would be the best solution
for this particular use case.

In light of that, we are simply removing the TODO.

Subject: [PATCH 1826/2315] Ensure that projects can be imported into Eclipse
 IDE

Recently the Spring Framework projects could no longer be imported into
Eclipse IDE without compilation errors in JMH sources.

This commit addresses this issue by applying workarounds for bugs in
Gradle and the JMH plugin for Gradle.

Gradle bug: https://github.com/gradle/gradle/issues/14932

JMH plugin bug: https://github.com/melix/jmh-gradle-plugin/issues/157

The Gradle bug has already been fixed in Gradle 6.8 RC1; however, the
issue for the JMH plugin bug seems not to have been triaged yet.

 MultipartWriterSupport

This commit only writes the 'charset' parameter in the written headers
if it is non-default (not UTF-8), since RFC7578 states that the only
allowed parameter is 'boundary'.

Subject: [PATCH 1838/2315] Refine kotlinx.serialization support

This commit introduces the following changes:
 - Converters/codecs are now used based on generic type info.
 - On WebMvc and WebFlux, kotlinx.serialization is enabled along
   to Jackson because it only serializes Kotlin @Serializable classes
   which is not enough for error or actuator endpoints in Boot as
   described on spring-projects/spring-boot#24238.

TODO: leverage Kotlin/kotlinx.serialization#1164 when fixed.

Closes gh-26147

 === Kotlin multiplatform serialization
 
 As of Spring Framework 5.3, https://github.com/Kotlin/kotlinx.serialization[Kotlin multiplatform serialization] is
-supported in Spring MVC, Spring WebFlux and Spring Messaging. The builtin support currently only targets JSON format.
-
-To enable it, follow https://github.com/Kotlin/kotlinx.serialization#setup[those instructions] and make sure neither
-Jackson, GSON or JSONB are in the classpath.
-
-NOTE: For a typical Spring Boot web application, that can be achieved by excluding `spring-boot-starter-json` dependency.
-
-In Spring MVC, if you need Jackson, GSON or JSONB for other purposes, you can keep them on the classpath and
-<<web#mvc-config-message-converters, configure message converters>> to remove `MappingJackson2HttpMessageConverter` and add
-`KotlinSerializationJsonHttpMessageConverter`.
+supported in Spring MVC, Spring WebFlux and Spring Messaging (RSocket). The builtin support currently only targets JSON format.
 
+To enable it, follow https://github.com/Kotlin/kotlinx.serialization#setup[those instructions] to add the related dependency and plugin.
+With Spring MVC and WebFlux, both Kotlin serialization and Jackson will be configured by default if they are in the classpath since
+Kotlin serialization is designed to serialize only Kotlin classes annotated with `@Serializable`.
+With Spring Messaging (RSocket), make sure that neither Jackson, GSON or JSONB are in the classpath if you want automatic configuration,
+if Jackson is needed configure `KotlinSerializationJsonMessageConverter` manually.

Subject: [PATCH 1840/2315] MessageHeaderAccessor handle self-copy correctly

1. Revert changes in setHeader from 5.2.9 that caused regression on self-copy.
2. Update copyHeaders to ensure it still gets a copy of native headers.
3. Exit if source and target are the same instance, as an optimization.

Closes gh-26155

Subject: [PATCH 1855/2315] Expose future response in new AsyncServerResponse

This commit introduces AsyncServerResponse, an extension of
ServerResponse that is returned from ServerResponse.async and that
allows users to get the future response by calling the block method.
This is particularly useful for testing purposes.

Subject: [PATCH 1856/2315] Remove spring.event.invoke-listener startup event

Prior to this commit, the `SimpleApplicationEventMulticaster` would be
instrumented with the `ApplicationStartup` and start/stop events for
invoking event listeners (`spring.event.invoke-listener`).

This feature was already limited to single-threaded event publishers,
but is still flawed since several types of events can happen
concurrently. Due to the single-threaded nature of the startup sequence,
our implementation should not produce startup events concurrently.

This can cause issues like gh-26057, where concurrent events lead to
inconcistencies when tracking parent/child relationships.

This commit removes the `spring.event.invoke-listener` startup event as
a result.

Fixes gh-26057

Subject: [PATCH 1858/2315] Optimization in ResourceArrayPropertyEditor

The previous implementation uses ArrayList for storing resolved
resources and ArrayList has O(n) time complexity for the contains
operation. By switching to the HashSet for storing resolved
resources we improve the time complexity of this operation to be O(1).

 When two pieces of the same type of advice (for example, two `@After` advice methods)
 defined in the same `@Aspect` class both need to run at the same join point, the ordering
 is undefined (since there is no way to retrieve the source code declaration order through

Subject: [PATCH 1897/2315] Fix NPE when calling NettyHeadersAdapter.add()

Prior to this commit, the `NettyHeadersAdapter` would directly delegate
the `add()` and `set()` calls to the adapted
`io.netty.handler.codec.http.HttpHeaders`. This implementation rejects
`null` values with exceptions.

This commit aligns the behavior here with other implementations, by not
rejecting null values but simply ignoring them.

Fixes gh-26274

Subject: [PATCH 1900/2315] Introduce computeAttribute() in AttributeAccessor

This commit introduces computeAttribute() as an interface default method
in the AttributeAccessor API. This serves as a convenience analogous to
the computeIfAbsent() method in java.util.Map.

Closes gh-26281

Subject: [PATCH 1908/2315] Update async dispatch check in OncePerRequestFilter

We no longer need to rely on an indirect check since Servlet 3.0 is expected
so we can just check the DispatcherType of the request.

Subject: [PATCH 1911/2315] Introduce ApplicationEvents to assert events
 published during tests

This commit introduces a new feature in the Spring TestContext
Framework (TCF) that provides support for recording application events
published in the ApplicationContext so that assertions can be performed
against those events within tests. All events published during the
execution of a single test are made available via the ApplicationEvents
API which allows one to process the events as a java.util.Stream.

The following example demonstrates usage of this new feature.

@SpringJUnitConfig(/* ... */)
@RecordApplicationEvents
class OrderServiceTests {

    @Autowired
    OrderService orderService;

    @Autowired
    ApplicationEvents events;

    @Test
    void submitOrder() {
        // Invoke method in OrderService that publishes an event
        orderService.submitOrder(new Order(/* ... */));
        // Verify that an OrderSubmitted event was published
        int numEvents = events.stream(OrderSubmitted.class).count();
        assertThat(numEvents).isEqualTo(1);
    }
}

To enable the feature, a test class must be annotated or meta-annotated
with @RecordApplicationEvents. Behind the scenes, a new
ApplicationEventsTestExecutionListener manages the registration of
ApplicationEvents for the current thread at various points within the
test execution lifecycle and makes the current instance of
ApplicationEvents available to tests via an @Autowired field in the
test class. The latter is made possible by a custom ObjectFactory that
is registered as a "resolvable dependency". Thanks to the magic of
ObjectFactoryDelegatingInvocationHandler in the spring-beans module,
the ApplicationEvents instance injected into test classes is
effectively a scoped-proxy that always accesses the ApplicationEvents
managed for the current test.

The current ApplicationEvents instance is stored in a ThreadLocal
variable which is made available in the ApplicationEventsHolder.
Although this class is public, it is only intended for use within the
TCF or in the implementation of third-party extensions.

ApplicationEventsApplicationListener is responsible for listening to
all application events and recording them in the current
ApplicationEvents instance. A single
ApplicationEventsApplicationListener is registered with the test's
ApplicationContext by the ApplicationEventsTestExecutionListener.

The SpringExtension has also been updated to support parameters of type
ApplicationEvents via the JUnit Jupiter ParameterResolver extension
API. This allows JUnit Jupiter based tests to receive access to the
current ApplicationEvents via test and lifecycle method parameters as
an alternative to @Autowired fields in the test class.

Closes gh-25616

+==== Application Events
+
+Since Spring Framework 5.3.3, the TestContext framework provides support for recording
+<<core.adoc#context-functionality-events, application events>> published in the
+`ApplicationContext` so that assertions can be performed against those events within
+tests. All events published during the execution of a single test are made available via
+the `ApplicationEvents` API which allows you to process the events as a
+`java.util.Stream`.
+
+To use `ApplicationEvents` in your tests, do the following.
+
+* Ensure that your test class is annotated or meta-annotated with
+  <<spring-testing-annotation-recordapplicationevents>>.
+* Ensure that the `ApplicationEventsTestExecutionListener` is registered. Note, however,
+  that `ApplicationEventsTestExecutionListener` is registered by default and only needs
+  to be manually registered if you have custom configuration via
+  `@TestExecutionListeners` that does not include the default listeners.
+* Annotate a field of type `ApplicationEvents` with `@Autowired` and use that instance of
+  `ApplicationEvents` in your test and lifecycle methods (such as `@BeforeEach` and
+  `@AfterEach` methods in JUnit Jupiter).
+** When using the <<testcontext-junit-jupiter-extension>>, you may declare a method
+   parameter of type `ApplicationEvents` in a test or lifecycle method as an alternative
+   to an `@Autowired` field in the test class.
+
+The following test class uses the `SpringExtension` for JUnit Jupiter and
+https://assertj.github.io/doc/[AssertJ] to assert the types of application events
+published while invoking a method in a Spring-managed component:
+
+// Don't use "quotes" in the "subs" section because of the asterisks in /* ... */
+[source,java,indent=0,subs="verbatim",role="primary"]

+			// Verify that an OrderSubmitted event was published
+			int numEvents = events.stream(OrderSubmitted.class).count(); // <3>
+			assertThat(numEvents).isEqualTo(1);
+		}
+	}
+----

Subject: [PATCH 1919/2315] Test status quo for repeatable @PropertySource on
 composed annotation

This commit introduces tests that verify support for using
@PropertySource as a repeatable annotation without the
@PropertySources container, both locally on an @Configuration class
and on a custom composed annotation.

Subject: [PATCH 1920/2315] Remove obsolete commandName attribute in
 spring-form.tld

Since support for the commandName attribute was removed from the
implementation of FormTag in Spring Framework 5.0, the presence of the
commandName attribute in the spring-form.tld file is no longer valid
and can lead one to assume that the commandName attribute is still
supported -- for example when using code completion in a JSP editor.

This commit therefore removes the obsolete commandName attribute in
spring-form.tld.

Closes gh-26337

Subject: [PATCH 1921/2315] Fix JdbcOperationsExtensions

This commit reverts some changes done in 2d5f9723fa9ba54480cffb650158f6a8e956e6c8
in order to fix JdbcOperations.queryForObject and
JdbcOperations.queryForList.

It is not possible to provide a vararg variant in Kotlin
for now due to a signature clash, but that will probably
make sense in Spring Framework 6 timeframe along to array
based variant removal for both Java and Kotlin.

Closes gh-26312

Subject: [PATCH 1930/2315] Avoid writing content-length twice in resource
 handling

Prior to this commit, the `ResourceHttpRequestHandler` would write the
resource size to the "Content-Length" response header.
This is already done by the underlying `ResourceHttpMessageConverter`
and `ResourceRegionHttpMessageConverter`.

This commit avoid this duplicate operation and delegates instead to the
converters.

Subject: [PATCH 1931/2315] Set content length on ServletHttpResponse

Prior to this commit, the `ServletServerHttpResponse` would copy headers
from the `HttpHeaders` map and calls methods related to headers exposed
as properties (content-type, character encoding).

Unlike its reactive variant, this would not set the content length.
Depending on the Servlet container implementation, this could cause
duplicate Content-Length response headers in the actual HTTP response.

This commit aligns both implementations and ensures that the
`setContentLengthLong` method is called if necessary so that the Servlet
container can ensure a single header for that.

Subject: [PATCH 1939/2315] Filter empty buffers PayloadMethodArgumentResolver

An empty buffer for RSocket is an empty message and while some codecs
such as StringDecoder may be able turn that into something such as an
empty String, for other formats such as JSON it is invalid input.

Closes gh-26344

if it is non-default (not UTF-8), since RFC7578 states that the only
allowed parameter is 'boundary'.

Instead of using a new bounded elastic scheduler per
DefaultPartHttpMessageReader instance, which creates daemon threads that
are not shut down, we now use the shared bounded elastic scheduler.

Subject: [PATCH 1944/2315] Fix headers keySet in WebFlux adapters

Prior to this commit, WebFlux native headers adapters would delegate the
`httpHeaders.keySet` to underlying implementations that do not honor the
`remove*` methods.

This commit fixes the `Set` implementation backing the
`httpHeaders.keySet` and ensures that headers can be safely removed from
the set.

Fixes gh-26361

 `DirtiesContextBeforeModesTestExecutionListener` and the
 `DirtiesContextTestExecutionListener`, which are enabled by default.
 
+.ApplicationContext lifecycle and console logging
+[NOTE]
+====
+When you need to debug a test executed with the Spring TestContext Framework, it can be
+useful to analyze the console output (that is, output to the `SYSOUT` and `SYSERR`
+streams). Some build tools and IDEs are able to associate console output with a given
+test; however, some console output cannot be easily associated with a given test.
+
+With regard to console logging triggered by the Spring Framework itself or by components
+registered in the `ApplicationContext`, it is important to understand the lifecycle of an
+`ApplicationContext` that has been loaded by the Spring TestContext Framework within a
+test suite.
+
+The `ApplicationContext` for a test is typically loaded when an instance of the test
+class is being prepared -- for example, to perform dependency injection into `@Autowired`
+fields of the test instance. This means that any console logging triggered during the
+initialization of the `ApplicationContext` typically cannot be associated with an
+individual test method. However, if the context is closed immediately before the
+execution of a test method according to <<spring-testing-annotation-dirtiescontext>>
+semantics, a new instance of the context will be loaded just prior to execution of the
+test method. In the latter scenario, an IDE or build tool may potentially associate
+console logging with the individual test method.
+
+The `ApplicationContext` for a test can be closed via one of the following scenarios.
+
+* The context is closed according to `@DirtiesContext` semantics.
+* The context is closed because it has been automatically evicted from the cache
+  according to the LRU eviction policy.
+* The context is closed via a JVM shutdown hook when the JVM for the test suite
+  terminates.
+
+If the context is closed according to `@DirtiesContext` semantics after a particular test
+method, an IDE or build tool may potentially associate console logging with the
+individual test method. If the context is closed according to `@DirtiesContext` semantics
+after a test class, any console logging triggered during the shutdown of the
+`ApplicationContext` cannot be associated with an individual test method. Similarly, any
+console logging triggered during the shutdown phase via a JVM shutdown hook cannot be
+associated with an individual test method.
+
+When a Spring `ApplicationContext` is closed via a JVM shutdown hook, callbacks executed
+during the shutdown phase are executed on a thread named `SpringContextShutdownHook`. So,
+if you wish to disable console logging triggered when the `ApplicationContext` is closed
+via a JVM shutdown hook, you may be able to register a custom filter with your logging
+framework that allows you to ignore any logging initiated by that thread.

+As of 5.3, non-null arguments will be enforced even after type conversion. If your handler

Subject: [PATCH 1955/2315] Prevent kotlinx.serialization usage on interfaces

Remove support for open polymorphic serialization in
kotlinx.serialization web converters and codecs in order
to prevent serialization handling suitable for Jackson
or other general purpose Java JSON libraries.

This will probably need further refinements for collections
for example, and could ultimately be fixed when
kotlinx.serialization will provide a dedicated function to
evaluate upfront if a type can be serialized or not.

Closes gh-26298

Subject: [PATCH 1980/2315] Fix contextPath request matching with PathPatterns

Prior to this commit, `SimpleUrlHandlerMapping` and other
implementations of `AbstractUrlHandlerMapping` would not strip the
Servlet context path from the request path before performing path
matching with PathPattern instances.

This resulted in requests not matching as expected if the application
was configured with a Servlet context path.

This commit ensures that the `RequestPath` "path whithin the
application" is used for matching against path patterns.

Fixes gh-26411

Subject: [PATCH 1987/2315] Unwrap proxied DataSources in
 SqlScriptsTestExecutionListener

Prior to this commit, if the DataSource in the
DataSourceFromTransactionManager was wrapped in a proxy implementing
InfrastructureProxy, SqlScriptsTestExecutionListener would throw an
exception stating that the DataSource in the ApplicationContext and the
DataSource in the DataSourceFromTransactionManager were not the same.

This commit unwraps both data sources and compares the underlying
target instances to check for equality.

In addition, this commit makes the unwrapResourceIfNecessary() method in
TransactionSynchronizationUtils public.

Subject: [PATCH 2014/2315] Improve handling for pre-flight requests

1. Update the HandlerMapping contract to state that CORS checks are expected
to be applied before returning a handler.

2. DispatcherHandler checks explicitly for pre-flight requests or CORS failed
requests and skips handling for both. Technically no change since
AbstractHandlerMapping already returns a NO_OP_HANDLER for those cases.
The purpose however is for the DispatcherHandler to also guarantee more
explicitly that no such handling can take place for such cases.

As one consequence, this makes it possible to invoke the DispatcherHandler from
anywhere in the WebFilter chain in order to "handle" a pre-flight request, and
then skip the rest of the WebFilter chain.

See gh-26257

Subject: [PATCH 2016/2315] Ignore null header value in MockHttpServletResponse

Prior to this commit, calls to setHeader() and addHeader() in
MockHttpServletResponse would result in an IllegalArgumentException or
NullPointerException if the supplied header value was null.

Although the Javadoc for setHeader(String, String) and
addHeader(String, String) in javax.servlet.http.HttpServletResponse
does not specify how a null header value should be handled, both Tomcat
and Jetty simply ignore a null value. Furthermore,
org.springframework.http.HttpHeaders.add(String, String) declares the
headerValue parameter as @Nullable.

This commit therefore updates MockHttpServletResponse to silently
ignore null header values passed to setHeader() and addHeader().

Closes gh-26488

Subject: [PATCH 2017/2315] Ignore null Locale in MockHttpServletResponse

Prior to this commit, calls to setLocale() MockHttpServletResponse
would result in a NullPointerException if the supplied Locale was null.

Although the Javadoc for setLocale(Locale) and addHeader(String, String)
in javax.servlet.ServletResponse does not specify how a null
Locale should be handled, both Tomcat and Jetty simply ignore a null
value.

This commit therefore updates MockHttpServletResponse to silently
ignore a null Locale passed to setLocale().

Closes gh-26493

Subject: [PATCH 2030/2315] Do not retain partial column metadata in
 SimpleJdbcInsert

Prior to this commit, if an SQLException was thrown while retrieving
column metadata from the database, SimpleJdbcInsert would generate an
INSERT statement that was syntactically valid but missing columns,
which could lead to data silently missing in the database (for nullable
columns).

This commit fixes this by clearing all collected column metadata if an
SQLException is thrown while processing the metadata. The result is
that an InvalidDataAccessApiUsageException will be thrown later while
generating the INSERT statement. The exception message now contains an
additional hint to make use of SimpleJdbcInsert#usingColumns() in order
to ensure that all required columns are included in the generated
INSERT statement.

SimpleJdbcCall can also encounter an SQLException while retrieving
column metadata for a stored procedure/function, but an exception is
not thrown since a later invocation of the stored procedure/function
will likely fail anyway due to missing arguments. Consequently, this
commit only improves the warning level log message by including a hint
to make use of SimpleJdbcCall#addDeclaredParameter().

Closes gh-26486

Subject: [PATCH 2031/2315] Fix in
 MockMultipartHttpServletRequest#getMultipartHeaders

Previously this method returned headers only when a Content-Type part header
was present. Now it is guaranteed to return headers (possibly empty) as long
as there is a MultipartFile or Part with the given name.

Closes gh-26501

Subject: [PATCH 2042/2315] Message broker skips messages with user destination

When a broker message handler is not configured with any prefixes, it will
process all messages by default, but user destination messages should be
pre-processed by the userDestinationMessageHandler first. This change
protects against that.

Closes gh-26474

Subject: [PATCH 2051/2315] Ensure StringDecoder supports multiline delimiters

This commit makes sure the StringDecoder supports stripping off
multi-line delimiters, such as \r\n. Specifically, we ensure that the
delimiter is stripped from the joined buffer.

Subject: [PATCH 2052/2315] Enforce standard Java types in YamlProcessor

`spring-beans` ships a `YamlProcessor` that's used as a base class by
`YamlMapFactoryBean` and `YamlPropertiesFactoryBean`. These
implementations have a clear use case: mapping application-internal Yaml
documents for configuration or infrastructure purposes.

Since this use case rarely requires extended types support from the
underlying library, and since we're offering ways to list custom types
(since #25152), we'll restrict to java standard types only by default.
This simplifies the setup and focuses the abstract class on the core
use cases.

Closes gh-26530

Subject: [PATCH 2054/2315] Check available processors in
 ParallelApplicationEventsIntegrationTests

This commit changes the condition in the if-block to check the number of
available processors instead of currently active threads with the hope
that doing so will prove more reliable on the CI server.

Subject: [PATCH 2060/2315] Update variable detection in
 UriComponentsBuilder#encode

This commit better aligns how URI variable placeholders are detected
in UriComponentsBuilder#encode (i.e. the pre-encoding of the literal
parts of a URI template) and how they are expanded later on.
The latter relies on a pattern that stops at the first closing '}'
which excludes the possibility for well-formed, nested placeholders
other than variables with regex syntax, e.g. "{year:\d{1,4}}".

UriComponentsBuilder#encode now also stops at the first closing '}' and
further ensures the placeholder is not empty and that it has '{' before
deciding to treat it as a URI variable.

Closes gh-26466

Subject: [PATCH 2061/2315] Ignore generics when Proxy is supplied to
 BeanUtils.copyProperties()

gh-24281 introduced support to honor generic type information in
BeanUtils.copyProperties(), but that introduced a regression.
Specifically, if the supplied source or target object lacked generic
type information for the return type of the read-method or the
parameter type of the write-method for a given property, respectively,
the two properties would be considered a mismatch and ignored. This can
occur if the source or target object is a java.lang.reflect.Proxy since
the dynamically generated class for the proxy loses the generic type
information from interfaces that the proxy implements.

This commit fixes this regression by ignoring generic type information
if either the source or target property is lacking generic type
information.

Closes gh-26531

Subject: [PATCH 2064/2315] Update ref docs for Inner class names

This commit updates the reference manual to point out that one may use
`.` instead of `$` as the nested class separator when providing a fully
qualified class name for a nested class in XML configuration.

This commit also updates the test for ClassUtils#forName to assert
support for `.` instead of `$`.

Closes gh-26540

Subject: [PATCH 2084/2315] Introduce a NativeDetector utility class

With the introduction of the -H:+InlineBeforeAnalysis native image
compiler flag in GraalVM 21.0.0, it is now possible to use an utility method and get code
removal at build time.

This flag will be enabled as of Spring Native 0.9.0.

 You can also use autowiring to avoid having to specify a dedicated bean definition at

 annotation. You can specify either `@Configurable(autowire=Autowire.BY_TYPE)` or
-`@Configurable(autowire=Autowire.BY_NAME` for autowiring by type or by name,

 at the field or method level (see <<beans-annotation-config>> for further details).

+operations and transformations via the `Path` API. It supports resolution as a `File` and
+as a `URL` and also implements the extended `WritableResource` interface. `PathResource`
+is effectively a pure `java.nio.path.Path` based alternative to `FileSystemResource` with
+different `createRelative` behavior.

+As can be seen above, this interface also defines a special `classpath*:` resource prefix

+expected to be a path without placeholders in this case -- for example,
+`classpath*:/config/beans.xml`. JAR files or different directories in the class path can

+If the `MyBean` class is refactored for use with annotation-driven configuration, the
+path to `myTemplate.txt` can be stored under a key named `template.path` -- for example,
+in a properties file made available to the Spring `Environment` (see
+<<beans-environment>>). The template path can then be referenced via the `@Value`
+annotation using a property placeholder (see <<beans-value-annotations>>). Spring will
+retrieve the value of the template path as a string, and a special `PropertyEditor` will
+convert the string to a `Resource` object to be injected into the `MyBean` constructor.

Subject: [PATCH 2113/2315] Support cookie w/ only Expires attribute in
 MockHttpServletResponse

Prior to this commit, MockHttpServletResponse only included the Expires
attribute in the generated Cookie header if the Max-Age attribute had
also been set.

This commit supports including the Expires attribute in the generated
Cookie Header even when the Max-Age attribute has not been set.

Closes gh-26558

Subject: [PATCH 2116/2315] Fix ResourceUrlProvider handler auto-detection

Prior to this commit, `ResourceUrlProvider` would listen and consider
all `ContextRefreshedEvent` and use the given context to detect
`SimpleUrlHandlerMapping`.

This could lead to situations where a `ResourceUrlProvider` uses another
application context than its own (in a parent/child context setup) and
detect the wrong set of handlers.

Because `ResourceUrlProvider` locks itself once the auto-detection is
done, we need to ensure that it considers only events sent by its
application context.

Fixes gh-26561

Subject: [PATCH 2123/2315] Support load-time weaving for @Component classes
 again

Since Spring Framework 5.2, the LoadTimeWeaver no longer weaves bean
classes annotated with @Component. This is a regression caused by the
changes in 40c62139ae, stemming from the fact that any class annotated
or meta-annotated with @Component is considered to be a candidate
configuration class in 'configuration lite' mode (i.e., a class without
the @Configuration annotation and without any @Bean methods) and
therefore now has its class eagerly loaded. This results in the class
being loaded before the LoadTimeWeaver has a chance to weave it.

This commit fixes this regression by explicitly avoiding eager class
loading for any 'lite' @Configuration or @Component class without @Bean
methods.

Closes gh-26199

+== Spring Properties
+
+{api-spring-framework}/core/SpringProperties.html[`SpringProperties`] is a static holder
+for properties that control certain low-level aspects of the Spring Framework. Users can
+configure these properties via JVM system properties or programmatically via the
+`SpringProperties.setProperty(String key, String value)` method. The latter may be
+necessary if the deployment environment disallows custom JVM system properties. As an
+alternative, these properties may be configured in a `spring.properties` file in the root
+of the classpath -- for example, deployed within the application's JAR file.
+
+The following table lists all currently supported Spring properties.
+
+.Supported Spring Properties
+|===
+| Name | Description
+
+| `spring.beaninfo.ignore`
+| Instructs Spring to use the `Introspector.IGNORE_ALL_BEANINFO` mode when calling the
+JavaBeans `Introspector`. See
+{api-spring-framework}++/beans/CachedIntrospectionResults.html#IGNORE_BEANINFO_PROPERTY_NAME++[`CachedIntrospectionResults`]
+for details.
+
+| `spring.expression.compiler.mode`
+| The mode to use when compiling expressions for the
+<<core.adoc#expressions-compiler-configuration, Spring Expression Language>>.
+
+| `spring.getenv.ignore`
+| Instructs Spring to ignore operating system environment variables if a Spring
+`Environment` property -- for example, a placeholder in a configuration String -- isn't
+resolvable otherwise. See
+{api-spring-framework}++/core/env/AbstractEnvironment.html#IGNORE_GETENV_PROPERTY_NAME++[`AbstractEnvironment`]
+for details.
+
+| `spring.index.ignore`
+| Instructs Spring to ignore the components index located in
+`META-INF/spring.components`. See <<core.adoc#beans-scanning-index, Generating an Index
+of Candidate Components>>.
+
+| `spring.jdbc.getParameterType.ignore`
+| Instructs Spring to ignore `java.sql.ParameterMetaData.getParameterType` completely.
+See the note in <<data-access.adoc#jdbc-batch-list, Batch Operations with a List of Objects>>.
+
+| `spring.jndi.ignore`
+| Instructs Spring to ignore a default JNDI environment, as an optimization for scenarios
+where nothing is ever to be found for such JNDI fallback searches to begin with, avoiding
+the repeated JNDI lookup overhead. See
+{api-spring-framework}++/jndi/JndiLocatorDelegate.html#IGNORE_JNDI_PROPERTY_NAME++[`JndiLocatorDelegate`]
+for details.
+
+| `spring.objenesis.ignore`
+| Instructs Spring to ignore Objenesis, not even attempting to use it. See
+{api-spring-framework}++/objenesis/SpringObjenesis.html#IGNORE_OBJENESIS_PROPERTY_NAME++[`SpringObjenesis`]
+for details.
+
+| `spring.test.constructor.autowire.mode`
+| The default _test constructor autowire mode_ to use if `@TestConstructor` is not present
+on a test class. See <<testing.adoc#integration-testing-annotations-testconstructor,
+Changing the default test constructor autowire mode>>.
+
+| `spring.test.context.cache.maxSize`
+| The maximum size of the context cache in the _Spring TestContext Framework_. See
+<<testing.adoc#testcontext-ctx-management-caching, Context Caching>>.
+
+| `spring.test.enclosing.configuration`
+| The default _enclosing configuration inheritance mode_ to use if
+`@NestedTestConfiguration` is not present on a test class. See
+<<testing.adoc#integration-testing-annotations-nestedtestconfiguration, Changing the
+default enclosing configuration inheritance mode>>.

Subject: [PATCH 2143/2315] Correctly set auto-growing array's element

Prior to this commit, the implementation of processKeyedProperty() in
AbstractNestablePropertyAccessor resulted in a
`java.lang.IllegalArgumentException: array element type mismatch` when
the property expression had more than one property key and the last key
should cause the array to grow automatically.

For example, given a property `int[][] multiArray` and property
expression `multiArray[1][3]`, the `processKeyedProperty()` method
created a new array object and assigned it to `multiArray`; whereas,
the new array object should have be assigned to `multiArray[1]`.

This commit fixes this issue.

Closes gh-26600

Subject: [PATCH 2146/2315] getResource can throw IllegalArgumentException

Class.getResource, ClassLoader.getResource, and ClassLoader.getSystemResource will throw IllegalArgumentException if a malformed URL is provided to them.

According to its javadoc, resolveURL should return null if not resolvable, so catch the IllegalArgumentException and return null.

Subject: [PATCH 2147/2315] Fix handling of file: paths to non-existent files

For setAsText, if the text argument is a file: URL for a path that does not exist, Paths.get(text) is called where text is a file: URL, which doesn't work - the result is an InvalidPathException.

To fix this issue, also check that the resource isn't a file before calling Paths.get(). That way, resources that are files skip to the other branch.

Subject: [PATCH 2153/2315] Cancel handling onError/Timeout in
 ServletHttpHandlerAdapter

This commit ensures handling is cancelled in case of onError/Timeout
callback from the Servlet container.

Separately we detect the same in ServletServerHttpRequest and
ServletServerHttpResponse, which signal onError to the read publisher
and cancel writing, but if the onError/Timeout arrives after reading
is done and before writing has started (e.g. longer handling), then
neither will reach handling.

Subject: [PATCH 2160/2315] Allow ServerHttpRequest content-type mutation

Prior to this commit, `ServerHttpRequest.mutate()` would not reflect
changes made on the "Accept" and "Content-Type" HTTP headers.
This was due to the fact that the instantiation of a new request based
on the mutated values would not use the writable HTTP headers used
during the mutation, but rather a read-only view of the headers backed
by `ReadOnlyHttpHeaders`.

`ReadOnlyHttpHeaders` caches those values for performance reasons, so
getting those from the new request would not reflect the changes made
during the mutation phase.

This commit ensures that the new request uses the mutated headers.

Fixes gh-26615

Subject: [PATCH 2161/2315] Ensure local @CrossOrigin maxAge overrides global
 value

Prior to this commit, a method-level @CrossOrigin maxAge value did not
override a class-level @CrossOrigin maxAge value. This contradicts the
Javadoc for @CrossOrgin which states the following.

    For those attributes where only a single value can be accepted such
    as allowCredentials and maxAge, the local overrides the global
    value.

This commit ensures that a method-level @CrossOrigin maxAge value
overrides a class-level @CrossOrigin maxAge value.

Closes gh-26619

Subject: [PATCH 2170/2315] Consolidate AsyncListener registration

Previously we registered 3 AsyncListener's from the request, from the
response, and from the Servlet adapter.

After this change, only the Servlet adapter registers a listener and
the others are delegated to. This consolidates the handling of
AsyncListener events so that it's easier to discover, trace, and
enforce the order of handling.

Subject: [PATCH 2189/2315] Publish directly to Maven Central

This commit skips the Bintray-related tasks in our CI pipeline and
instead relies on Maven Central for publishing Spring Framework
artifacts.

This commit also updates the CI pipeline to sign the artifacts directly
with the `artifactory-resource`.

Closes gh-26654

Subject: [PATCH 2196/2315] Support multiple parsing patterns in
 @DateTimeFormat

Prior to this commit, @DateTimeFormat only supported a single format
for parsing date time values via the style, iso, and pattern attributes.

This commit introduces a new fallbackPatterns attribute that can be
used to configure multiple fallback patterns for parsing date time
values. This allows applications to accept multiple input formats for
date time values.

For example, if you wish to use the ISO date format for parsing and
printing but allow for lenient parsing of user input for various
additional date formats, you could annotate a field or method parameter
with configuration similar to the following.

    @DateTimeFormat(
        iso = ISO.DATE,
        fallbackPatterns = { "M/d/yy", "dd.MM.yyyy" }
    )

Subject: [PATCH 2218/2315] Introduce Gradle Toolchain support in build

Prior to this commit, the Spring Framework build would rely on
setting a custom Java HOME for building all sources and tests
with that JDK.

This approach is not flexible enough, since we would be testing
the source compatibility against a recent JDK, but not a common
case experienced by the community: compiling and running
application code with a recent JDK and the official, JDK8-based
Framework artifacts.
This method is also limiting our choice of JDKs to the ones
currently supported by Gradle itself.

This commit introduces the support of Gradle JVM Toolchains in
the Spring Framework build.

We can now select a specific JDK for compiling the main
SourceSets (Java, Groovy and Kotlin) and another one for
compiling and running the test SourceSets:

`./gradlew check -PmainToolChain=8 -PtestToolchain=15`

Gradle will automatically find the JDKs present on the host or
download one automcatically. You can find out about the ones
installed on your host using:

`./gradlew -q javaToolchains`

Finally, this commit also refactors the CI infrastructure to:

* only have a single CI image (with all the supported JDKs)
* use this new feature to compile with JDK8 but test it
against JDK11 and JDK15.

Closes gh-25787

-// This script adds support for the following two JVM system properties
-// that control the build for alternative JDKs (i.e., a JDK other than
-// the one used to launch the Gradle process).
-//
-// - customJavaHome: absolute path to the alternate JDK installation to
-//     use to compile Java code and execute tests. This system property
-//     is also used in spring-oxm.gradle to determine whether JiBX is
-//     supported.
-//
-// - customJavaSourceVersion: Java version supplied to the `--release`
-//     command line flag to control the Java source and target
-//     compatibility version. Supported versions include 9 or higher.
-//     Do not set this system property if Java 8 should be used.
-//
-// Examples:
-//
-// ./gradlew -DcustomJavaHome=/Library/Java/JavaVirtualMachines/jdk-14.jdk/Contents/Home test
-//
-// ./gradlew --no-build-cache -DcustomJavaHome=/Library/Java/JavaVirtualMachines/jdk-14.jdk/Contents/Home test
-//
-// ./gradlew -DcustomJavaHome=/Library/Java/JavaVirtualMachines/jdk-14.jdk/Contents/Home -DcustomJavaSourceVersion=14 test

Subject: [PATCH 2229/2315] Fix release pipeline for Maven Central publication

This commit fixes the missing pieces in our Maven Central publication
pipeline. Our first attempt at releasing with it showed a few problems:

* the promote task did not have the artifacts downladed with the
  artifactory repository
* we applied the wrong Sonatype credentials to the task
* the github changelog task would fail because of docker rate limiting
  since we were not using the right type of resource, which is
  configured with the proper caching mechanism

Subject: [PATCH 2233/2315] Honor class-level @DirtiesContext if test class is
 disabled via SpEL

Prior to this commit, if a test class annotated with @DirtiesContext
and @EnabledIf/@DisabledIf with `loadContext = true` was disabled due
to the evaluated SpEL expression, the ApplicationContext would not be
marked as dirty and closed.

The reason is that @EnabledIf/@DisabledIf are implemented via JUnit
Jupiter's ExecutionCondition extension API which results in the entire
test class (as well as any associated extension callbacks) being
skipped if the condition evaluates to `disabled`. This effectively
prevents any of Spring's TestExecutionListener APIs from being invoked.
Consequently, the DirtiesContextTestExecutionListener does not get a
chance to honor the class-level @DirtiesContext declaration.

This commit fixes this by implementing part of the logic of
DirtiesContextTestExecutionListener in
AbstractExpressionEvaluatingCondition (i.e., the base class for
@EnabledIf/@DisabledIf support). Specifically, if the test class for an
eagerly loaded ApplicationContext is disabled,
AbstractExpressionEvaluatingCondition will now mark the test
ApplicationContext as dirty if the test class is annotated with
@DirtiesContext.

Closes gh-26694

Subject: [PATCH 2258/2315] Support "Accept-Patch" for unsupported media type

This commit introduces support in both servlet and webflux for the
"Accept-Patch" header, which is sent when the client sends unsupported
data in PATCH requests.
See  section 2.2 of RFC 5789.

Closes gh-26759

Subject: [PATCH 2265/2315] Recreate file storage directory when removed in
 DefaultPartHttpMessageReader

Some operating systems delete temp files not just when booting up, but
also during operation. This commit makes sure that the
DefaultPartHttpMessageReader recreates the directory used to store
files in, if it's not there.

Subject: [PATCH 2266/2315] Retain root cause for parsing patterns in
 @DateTimeFormat

The support for fallback parsing patterns in @DateTimeFormat introduced
in gh-20292 introduced a regression in that the original cause of the
parsing exception was no longer retained.

This commit ensures that the original DateTimeParseException is set as
the cause for any newly created DateTimeParseException, thereby
retaining the original exception as the root cause.

Subject: [PATCH 2290/2315] Retain root cause for parsing patterns in
 @DateTimeFormat

The support for fallback parsing patterns in @DateTimeFormat introduced
in gh-20292 introduced a regression in that the original cause of the
parsing exception was no longer retained.

gh-26777 addressed that regression for `java.time` support; whereas,
this commit addresses that regression for legacy Date types.

This commit ensures that the original ParseException is set as the
cause for any newly created ParseException, thereby retaining the
original exception as the root cause.

Subject: [PATCH 2292/2315] Ensure @DateTimeFormat tests pass on Java 9+

Prior to this commit, two tests for exception handling regarding
@DateTimeFormat processing only passed on Java 8. This is due to the
fact that the toString() implementation for annotations changed in Java
9. Specifically, the representation for arrays changed from [] to {},
and strings are enclosed in double quotes beginning with Java 9.

This commit ensures that the affected @DateTimeFormat tests pass on
Java 9+, by making the assertions more lenient regarding toString()
output for annotations.

See gh-26777

Subject: [PATCH 2293/2315] Polish CronTriggerTests and assess daylight savings
 time issue

This test polishes CronTriggerTests and modifies the
daylightSavingMissingHour() test to help analyze why the test fails
for CET if the minute value for the last completion time falls between
0 and 9 minutes.

Subject: [PATCH 2308/2315] Avoid exceptions when evaluating validation hints

Prior to this commit, evaluating validation hints for
@javax.validation.Valid caused exceptions being raised when getting the
value of this annotation, which does not exist. Bypassing
AnnotationUtils.getValue() in those cases can improve performance by
avoiding the cost incurred by raising exceptions.

Subject: [PATCH 2309/2315] Copy HttpStatus::values to prevent allocation

Before this commit, HttpStatus::resolve used the values() method in its
logic. This causes a new array to be allocated for each invocation,
and results in memory overhead.

This commit makes a copy of the HttpStatus values array, and uses that
to resolve status codes.

Closes gh-26842

+=== Path Matching
+
+The Servlet API exposes the full request path as `requestURI` and further sub-divides it
+into `contextPath`, `servletPath`, and `pathInfo` whose values vary depending on how a
+Servlet is mapped. From these inputs, Spring MVC needs to determine the lookup path to
+use for handler mapping, which is the path within the mapping of the `DispatcherServlet`
+itself, excluding the `contextPath` and any `servletMapping` prefix, if present.
+
+The `servletPath` and `pathInfo` are decoded and that makes them impossible to compare
+directly to the full `requestURI` in order to derive the lookupPath and that makes it
+necessary to decode the `requestUri`. However this introduces its own issues because the
+path may contain encoded reserved characters such as `"/"` or `";"` that can in turn
+alter the structure of the path after they are decoded which can also lead to security
+issues. In addition, Servlet containers may normalize the `servletPath` to varying
+degrees which makes it further impossible to perform `startsWith` comparisons against
+the `requestUri`.
+
+This is why it is best to avoid reliance on the `servletPath` which comes with the
+prefix-based `servletPath` mapping type. If the `DispatcherServlet` is mapped as the
+default Servlet with `"/"` or otherwise without a prefix with `"/*"` and the Servlet
+container is 4.0+ then Spring MVC is able to detect the Servlet mapping type and avoid
+use of the `servletPath` and `pathInfo` altogether. On a 3.1 Servlet container,
+assuming the same Servlet mapping types, the equivalent can be achieved by providing
+a `UrlPathHelper` with `alwaysUseFullPath=true` via <<mvc-config-path-matching>> in
+the MVC config.
+
+Fortunately the default Servlet mapping `"/"` is a good choice. However, there is still
+an issue in that the `requestUri` needs to be decoded to make it possible to compare to
+controller mappings. This is again undesirable because of the potential to decode
+reserved characters that alter the path structure. If such characters are not expected,
+then you can reject them (like the Spring Security HTTP firewall), or you can configure
+`UrlPathHelper` with `urlDecode=false` but controller mappings will need to match to the
+encoded path which may not always work well. Furthermore, sometimes the
+`DispatcherServlet` needs to share the URL space with another Servlet and may need to
+be mapped by prefix.
+
+The above issues can be addressed more comprehensively by switching from `PathMatcher` to
+the parsed `PathPattern` available in 5.3 or higher, see
+<<mvc-ann-requestmapping-pattern-comparison>>. Unlike `AntPathMatcher` which needs
+either the lookup path decoded or the controller mapping encoded, a parsed `PathPattern`
+matches to a parsed representation of the path called `RequestPath`, one path segment
+at a time. This allows decoding and sanitizing path segment values individually without
+the risk of altering the structure of the path. Parsed `PathPattern` also supports
+the use of `servletPath` prefix mapping as long as the prefix is kept simple and does
+not have any characters that need to be encoded.
