Avoid the need to specify Supplier in Kotlin bean registration API [SPR-15118]

[spring-projects-issues]

Sébastien Deleuze opened SPR-15118 and commented

Based on an idea from Mario Arias, we can avoid requiring specifying explicitly Supplier lambda type in Kotlin API by declaring the supplier parameter as crossinline supplier: () -> T instead of supplier: Supplier<T>.

These 2 additional commits (c5cfd8c, 6ee5e2a) now allows to write the 100% Kotlin idiomatic code with pure functions:

val context = GenericApplicationContext()
context.registerBean(Foo::class)
context.registerBean{ Bar(it.getBean(Foo::class)) }
