This commit introduces new AOT processors that look for
`@RSocketExchange` annotated methods on interfaces implemented by beans
and registers reachability metadata accordingly:
* JDK proxies for the beans themselves
* invocation reflection for annotated methods
* binding reflection for arguments and return types
This allows to compile such clients to Native Images.
Closes gh-29877
LocalVariableTableParameterNameDiscoverer is not registered by default anymore now.
Java sources should be compiled with `-parameters` instead (available since Java 8).
Also retaining standard Java parameter names for all of Spring's Kotlin sources now.
Closes gh-29531
As of Java 18, the serial lint warning in javac has been expanded to
check for class fields that are not marked as `Serializable`.
See https://www.oracle.com/java/technologies/javase/18all-relnotes.html#JDK-8202056
In the Spring Framework codebase, this can happen with `Map`, `Set` or
`List` attributes which are often assigned with an unmodifiable
implementation variant. Such implementations are `Serializable` but
cannot be used as field types.
This commit ensures that the following changes are applied:
* fields are marked as transient if they can't be serialized
* classes are marked as `Serializable` if this was missing
* `@SuppressWarnings("serial")` is applied where relevant
This commit fixes Kotlin Serialization converter
registration logic in RestTemplate,
AbstractMessageBrokerConfiguration and
AllEncompassingFormHttpMessageConverter classes
to be similar to the one in
WebMvcConfigurationSupport.
Closes gh-29008
Includes runtime storing of generated classes to a directory specified by the "cglib.generatedClasses" system property. Avoids lazy CGLIB fast-class generation and replaces generated Enhancer and MethodWrapper key classes with equivalent record types. Introduces support for early type determination in InstantiationStrategy, AopProxy and SmartInstantiationAwareBeanPostProcessor - in order to trigger CGLIB class generation in refreshForAotProcessing (through early determineBeanType calls for bean definitions).
Closes gh-28115
This commit deprecates ListenableFuture in favor of CompletableFuture.
ListenableFuture was introduced in Spring Framework 4.0, when
CompletableFuture was not yet available. Spring now requires JDK 17, so
having our own type no longer seems necessary.
Major changes in this commit include:
- Deprecation of ListenableFuture and related types
(ListenableFutureCallback, SettableListenableFuture, etc.)
- Deprecation of AsyncListenableTaskExecutor in favor of default methods
in AsyncTaskExecutor (submitCompletable).
- AsyncHandlerMethodReturnValueHandler now has toCompletableFuture
instead of toListenableFuture.
- WebSocketClient now has execute methods, which do the same as
doHandshake, but return CompletableFutures (cf. the reactive
WebSocketClient).
All other changes
- add an overloaded method that takes a CompletableFuture parameter
instead of ListenableFuture, and/or
- add a method with a 'Async' suffix that returns a CompletableFuture
instead of a ListenableFuture (connectAsync, sendAsync).
Closes gh-27780
This commit deprecates all methods in org.springframework.scheduling
that use
- Date, in favor of variants that take an Instant.
- long & TimeUnit, in favor of variants that take a Duration.
Closes: gh-28714
