This commit review the support for AOT by only ignoring beans that are
using an instance supplier. The Kotlin DSL has a way to register a
bean by type where all inferences should happen as usual and that was
previously ignored.
This commit no longer ignores those beans so AOT can optimize them, and
makes sure that they are not registered again when running with AOT
optimizations. This change makes it so that the order in which beans are
registered is now different when running with AOT optimizations, and
we'll have to find a solution for that.
See gh-29555
This commit adds AOT/Native support for beans that are contributed by
the Kotlin DSL.
Since they use an instance supplier, such beans are now configured to
be ignored by AOT generation. They are part of the bean factory still
so any hint generation works.
This commit removes a previous attempt at fixing this issue when we
were not checking for instance suppliers. Rather than skipping the
initializr at runtime, it runs again as intended since their state
can't be stored in AOT-generated code.
Closes gh-29555
This commit adds support for Kotlin BeanPostProcessor beans which should
be defined in a companion object and annotated with `@JvmStatic`.
Closes gh-32946
This commit adds Coroutines support for `@Cacheable`.
It also refines SimpleKeyGenerator to ignore Continuation
parameters (Kotlin does not allow to have the same method
signature with both suspending and non-suspending variants)
and refines
org.springframework.aop.framework.CoroutinesUtils.awaitSingleOrNull
in order to wrap plain value to Mono.
Closes gh-31412
This commit reverts the deprecation of CommandLinePropertySource and
SimpleCommandLinePropertySource, since we have discovered that Spring
Boot actively uses SimpleCommandLinePropertySource in
org.springframework.boot.SpringApplication.
Closes gh-31207
This commit adds support for `@Scheduled` annotation on reactive
methods and Kotlin suspending functions.
Reactive methods are methods that return a `Publisher` or a subclass
of `Publisher`. The `ReactiveAdapterRegistry` is used to support many
implementations, such as `Flux`, `Mono`, `Flow`, `Single`, etc.
Methods should not take any argument and published values will be
ignored, as they are already with synchronous support.
This is implemented in `ScheduledAnnotationReactiveSupport`, which
"converts" Publishers to `Runnable`. This strategy keeps track of
active Subscriptions in the `ScheduledAnnotationBeanPostProcessor`,
in order to cancel them all in case of shutdown.
The existing scheduling support for tasks is reused, aligning the
triggering behavior with the existing support: cron, fixedDelay and
fixedRate are all supported strategies.
If the `Publisher` errors, the exception is logged at warn level and
otherwise ignored. As a result new `Runnable` instances will be
created for each execution and scheduling will continue.
The only difference with synchronous support is that error signals
will not be thrown by those `Runnable` tasks and will not be made
available to the `org.springframework.util.ErrorHandler` contract.
This is due to the asynchronous and lazy nature of Publishers.

An ArrayIndexOutOfBoundsException is thrown by
Validator.getConstraintsForClass when processing Kotlin beans
with extensions functions (Kotlin or Hibernate Validator bug).
This commit catches those exceptions and report them as warning
without the full stactrace, and report as well other
ones thrown as errors with the full stracktrace.
Closes gh-30037
This commit leverages Hibernate Validator's own internal use
of standard Java reflection to perform validation on suspending
function, which fixes the ArrayIndexOutOfBoundsException previously
observed.
Validation of suspending function return values remains unsupported
as Hibernate Validator is not Coroutines aware.
Closes gh-23499
Kotlin reflection API invocation on a specific function
may require iterating on all Java methods to find the right
Kotlin function. As a consequence, this commit adds introspection
hints on the class declared methods for all Kotlin beans since
the impact on the footprint is low.
Closes gh-29663
This commit harmonizes the registration of an executable so that
the default method and the method that takes an empty customizer
produces the same hint. The same applies to the readable flag of
a field hint.
Rather than returning a list of executable modes, the "highest" mode
is retained.
See gh-29011
This commit removes the JUnit 4 dependency from all modules except
spring-test which provides explicit JUnit 4 support.
This commit also includes the following.
- migration from JUnit 4 assertions to JUnit Jupiter assertions in all
Kotlin tests
- migration from JUnit 4 assumptions in Spring's TestGroup support to
JUnit Jupiter assumptions, based on org.opentest4j.TestAbortedException
- introduction of a new TestGroups utility class than can be used from
existing JUnit 4 tests in the spring-test module in order to perform
assumptions using JUnit 4's Assume class

This commit updates Kotlin beans DSL in order to support
creating beans using callable references with autowired
parameters. Type resolution is implemented using Kotlin
reified type parameters without requiring reflection.
Closes gh-21845
Spring Framework 5.1.0 exposed by mistake context in the Kotlin bean DSL
API in order to fix SPR-16269. Now that BeanFactory#getBeanprovider is
available, it should be exposed via a provider<Foo>() function in order
to provide a more clean API instead.
Issue: SPR-17352
Since non-default constructors are now evaluated for autowiring,
there is no need anymore for setting autowiring mode or exposing
it in Kotlin bean DSL.
Issue: SPR-17292
This commit introduces a deferred initialization of the declared beans
in order to make it possible to access to the environment (and even
to the context for advanced use-cases) in the beans { } Kotlin DSL.
Issues: SPR-16269, SPR-16412
