Jersey HttpServletResponse Injection #62
Description
From the docs, I can inject an HttpServletRequest using the following:
ResourceConfig app = new ResourceConfig()
.packages("com.amazonaws.serverless.proxy.test.jersey")
.register(new AbstractBinder() {
@Override
protected void configure() {
bindFactory(AwsProxyServletRequestFactory.class)
.to(HttpServletRequest.class)
.in(RequestScoped.class);
bindFactory(AwsProxyServletContextFactory.class)
.to(ServletContext.class)
.in(RequestScoped.class);
}
});
And I can access the HttpServletRequest using:
@Path("/my-servlet") @GET
public String echoServletHeaders(@Context HttpServletRequest context) {
Enumeration<String> headerNames = context.getHeaderNames();
while (headerNames.hasMoreElements()) {
String headerName = headerNames.nextElement();
}
return "servlet";
}
However, I have not found a way to inject the HttpServletResponse. It would be nice to bind a factory method like:
bindFactory(AwsProxyServletResponseFactory.class)
.to(HttpServletResponse.class)
.in(RequestScoped.class);
So that I can access the HttpServletResponse using the @context object, e.g. something like:
@Path("/my-servlet") @GET
public String echoServletHeaders(@Context HttpServletRequest request, @Context HttpServletResponse) {
//stuff
}
If this is not possible, is there another way to inject the HttpServletResponse? I tried using the @context above the @path, but the HttpServletResponse always returns null. Here is a snippet of what I tried:
@Context private ServletContext myContext;
@Context private HttpServletResponse httpResponse;
@Path("/saml")
@POST
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_FORM_URLENCODED)
public Response processSAML(@Context HttpServletRequest httpRequest) {
//httpResponse is null
