This commit harmonizes the package space by moving the TestCompiler
infrastructure from the now outdated "generator" package to "generate".
Closes gh-29082
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 makes use of the new `getLazyResolutionProxyClass` on
`AutowireCandidateResolver` to detect if a injection point requires
a proxy.
Closes gh-28980
Further refinements will be required for
MethodValidationPostProcessor since @Lazy
used by Spring Boot is not supported yet
for that use case.
See gh-28980
Instead of individual last-minute clearing in markBeanAsCreated, the factory clears all merged bean definitions in freezeConfiguration, retaining the changes of merged bean definition post-processing after that point (in particular in refreshForAotProcessing).
Closes gh-28948
Tests with the agent are broken now that hints for an annotation is
no longer required if the annotated element has an introspection hint.
See gh-28967
This commit updates RuntimeHintsUtils to focus on registering a JDK
proxy only as annotations of annotated elements that have at least
an introspection hints are visible out-of-the-box.
This commit also removes unnecessary hints and adapt `@Reflective` to
detect if a hint is required using the introduced
MergedAnnotation#isSynthesizable.
See gh-28967
This commit updates the hints of a Cglib proxy's target type so that
methods can be invoked and constructors can be introspected. The former
is needed as a cglib proxy invokes the target type via reflection. As
for that latter, this is required at least by
Enhancer#filterConstructors.
See gh-28954
This commit expands GeneratedClassHandler to allow invocation of
declared fields and methods. Generated proxies have a number of
internal fields and methods that are invoked via reflection.
See gh-28954
This commit updates ApplicationContextAotGenerator to register a
handler that process Cglib generated classes. The handler registers
such classes to the GeneratedFiles and provide a hint so that it
can be instantiated using reflection.
Closes gh-28954
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 updates refresh for AOT processing so that the configuration
is frozen before invoking MergedBeanDefinitionPostProcessor instances.
This makes sure that post-processed MergedBeanDefinitions are kept in
cache and not lost if a component attempts to clear the metadata cache.
Closes gh-28941
NestedIOException has been removed in Spring Framework 6 and this commit
marks it as deprecated in 5.x. Users that were relying on this exception
should use IOException directly.
Closes gh-28929
This commit updates ImportAwareAotBeanPostProcessor to be priority
ordered, with the same order as its original BeanPostProcessor. This
makes sure that infrastructure beans can be post-processed if
necessary
See gh-28915
This commit adapts the generated code for handling ImportAware to
register a bean definition rather than adding the BeanPostProcessor
directly on the beanFactory. The previous arrangement put the
post processor handling import aware callbacks first on the list,
leading to inconsistent callback orders.
Tests have been adapted to validate this exact scenario.
Closes gh-28915
Add an `AotServices` class to replace `AotFactoriesLoader`. The
replacement class allow instances to be loaded from just the
`aot.factories` file if required. It also retains a link to the bean
names so that a `findByBeanName(...)` method can be provided.
See gh-28833
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 polishes DefaultGenerationContext to make the method
that flushes generated classes more explicit. It now throws an
IOException and TestGenerationContext has been updated to handle
that to ease its use in code that can't throw such an exception.
As this use case is likely to happen outside the Spring Framework,
this commit adds such a convenience to spring-test as well.
Closes gh-28877
This commit registers the MergedBeanDefinitionPostProcessor instances
on the BeanFactory processed for AOT purposes. This allows beans that
are created at build-time to be post-processed for low-level needs such
as initialization and autowiring.
Closes gh-28777
Migrate all AOT tests to make use of `GeneratedClasses` rather than
directly generating Java files. This commit also refines and polishes
AOT APIs to being greater consistency.
Specifically:
- The `MethodGenerator` interface has been removed in favor of
working directly with `GeneratedMethods`.
- The visibility of several constructors and methods has been
reduced to package-private.
- The `using(...)` and `builder` methods have been removed in
favor of setting the `Consumer` callbacks directly as
constructor arguments.
- Variable names for builders are now named `type` or `method`
depending on what they're building.
Closes gh-28831
Prior to this commit, when users wished to register proxy hints for a
Spring AOP JDK dynamic proxy, they were required to explicitly specify
SpringProxy, Advised, and DecoratingProxy along with user interfaces.
This commit simplifies hint registration for Spring AOP proxies by
introducing two completeJdkProxyInterfaces() methods in AopProxyUtils,
one that accepts strings and one that accepts classes that represent
the user-specified interfaces implemented the user component to be
proxied. The SpringProxy, Advised, and DecoratingProxy interfaces are
appended to the user-specified interfaces and returned as the complete
set of interfaces that the proxy will implement.
Closes gh-28745
This commit replaces convention-based annotation attribute overrides in
tests with explicit use of @AliasFor -- except for tests in spring-core,
since we still want to test our support for convention-based annotation
attribute overrides.
See gh-28760
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
The previous change to the tests resulted in a failure on Windows when
using the DefaultResourceLoader by expecting an exception when no
exception is thrown.
This commit narrows the scope of the if-clause to expect an exception
only when using the FileSystemResourceLoader on Windows.
See gh-28703, gh-28746
The tests introduced in commit 9868c28c73 pass on Mac OS and Linux but
fail on Microsoft Windows.
This commit updates the tests so that they pass on MS Windows as well.
See gh-28703
Closes gh-28746
This commit adds new tests for the `ApplicationContextAotGenerator`,
this time leveraging the `RuntimeHintsAgent` that checks the need for
runtime hints at runtime.
See gh-27981
When the ProtocolResolver SPI was introduced in Spring Framework 4.3,
support for protocol resolvers was added in DefaultResourceLoader's
getResource() implementation; however, GenericApplicationContext's
overridden getResource() implementation was not updated accordingly.
Prior to this commit, if a GenericApplicationContext was configured
with a custom ResourceLoader, registered protocol resolvers were
ignored.
This commit ensures that protocol resolvers are honored in
GenericApplicationContext even if a custom ResourceLoader is used.
Closes gh-28703
This commit moves the responsibility of naming classes to the
GenerationContext. This was already largely the case before, except that
the concept of a "mainTarget" and "featureNamePrefix" was specific
to bean factory initialization contributors.
ClassNameGenerator should now be instantiated with a default target
and an optional feature name prefix. As a result, it does no longer
generate class names in the "__" package.
GeneratedClasses can now provide a new, unique, GeneratedClass or
offer a container for retrieving the same GeneratedClass based on an
identifier. This lets all contributors use this facility rather than
creating JavaFile manually. This also means that ClassNameGenerator
is no longer exposed.
Because the naming conventions are now part of the GenerationContext, it
is required to be able to retrieve a specialized version of it if a
code generation round needs to use different naming conventions. A new
withName method has been added to that effect.
Closes gh-28585
Since LoggingCacheErrorHandler was only recently introduced in 5.3.16,
we have decided to completely revise its internals (protected API) in
5.3.x while retaining the current public API.
Specifically, this commit:
- introduces protected getLogger() and isLogStackTraces() methods to
improve extensibility
- revises logCacheError() to accept a Supplier<String> for lazy
resolution of error messages
Closes gh-28672
See gh-28670, gh-28648
At present, creating a LoggingCacheErrorHandler that logs stack traces
also requires supplying the logger to be used. This might be
inconvenient for some users, as it requires usage of the Commons
Logging API.
This commit simplifies creation of such as LoggingCacheErrorHandler
instance by adding a constructor that only accepts a boolean flag
indicating whether to log stack traces.
Closes gh-28670
Most importantly, static @Bean methods do not expose their @Configuration class-level annotations anymore, aligned with the behavior for non-static @Bean methods.
Closes gh-28298
Includes deprecation of NestedServletException, whereas NestedCheckedException and NestedRuntimeException remain as base classes with several convenience methods.
Closes gh-25162
The `RuntimeHints` API allows to describe hints for the reflection,
proxies and resources behavior at runtime. The need for a particular
behavior can be covered by several types of hints, at different levels.
This knowledge can be important in several cases:
* before contributing additional hints, infrastructure can check if an
existing hint already covers the behavior
* this can be used in test suites and test infrastructure
This commit adds a new RuntimeHintsPredicates that generates `Predicate`
instances for testing `RuntimeHints` against a desired runtime behavior
for reflection, resources or proxies.
Closes gh-28555
We use Grafana to monitor our app via Spring's JMX exporter, and we
think it could be interesting to have at least the current queue size
for this purpose since the queue size directly affects the app memory
load. Having the queue capacity seems also interesting to set up
triggers whose values are calculated based on the maximum capacity of
the queue.
This commit introduces new getCurrentQueueSize() and getQueueCapacity()
methods in ThreadPoolTaskExecutor.
See gh-28583
Refine the class name logic so that the name is passed in rather
than using `ApplicationContext.getId()`. Also propagate the name
so that the generated classes use it.
See gh-28565
Update `ApplicationContextAotGenerator` so that it can generate class
names based on a `target` class and using the ID of the application
context. Prior to this commit, the generated class name was always
`__.BeanFactoryRegistrations`.
Closes gh-28565
This commit adds a central utility to figure out if the application
must run with Ahead-Of-Time optimizations. This is mandatory for running
in a native image but can be selected on the JVM using the
"spring.aot.enabled" property.
This commit also introduces a utility that can be used to initialize a
context with generated artifacts. This represents the runtime
counterpart of ApplicationContextAotGenerator.
Closes gh-28474
Prior to this commit, the hints conditions were only supported for the
`TypeHint` case. GraalVM generally expanded this concept to all hints
and we should do the same.
Right now, only the `typeReachable` condition is available but we should
design for possible future additions.
This commit introduces a new `ConditionalHint` contract implemented by
all hints compatible with this approach. The condition information is
also used in all configuration writers as a result.
Closes gh-28126
This commit adds a `@Reflective` annotation that can be used to declare
that the annotated element requires reflection at runtime. By default,
the annotated element is exposed but this can be customized by
specifying a dedicated `ReflectiveProcessor`.
Closes gh-28469
A static nested class does not keep an implicit reference to its
enclosing instance.
This prevents a common cause of memory leaks and uses less memory per
instance of the class.
Closes gh-28433
Prior to this commit, we could only contribute `RuntimeHints` through
two mechanisms:
* `AotContributingBeanFactoryPostProcessor`, consdering the entire
`BeanFactory` and designed for contributing both code and hints.
* `AotContributingBeanPostProcessor`, consdering beans one by one, but
also designed for contributing both code and hints.
There are cases where libraries and applications want to contribute
`RuntimeHints` only, in a more static fashion: a dependency being
present, or a piece of infrastructure being considered by the
application context are good enough signals to contribute hints about
resources or reflection.
This commit adds the `RuntimeHintsRegistrar` contract for these cases.
Implementations can be declared as `spring.factories` and they will be
processed as soon as they're detected on the classpath. They can also be
declared with `@ImportRuntimeHints` and they will be processed if the
annotated bean definition is considered in the application context.
This annotation should be mainly used on configuration classes and on
bean methods.
```
@Configuration
@ImportRuntimeHints(CustomRuntimeHintsRegistrar.class)
public class MyConfiguration {
@Bean
@ImportRuntimeHints(OtherRuntimeHintsRegistrar.class)
public MyBean myBean() {
//...
}
}
```
