Prior to this commit, ControlFlowPointcut supported a single method
name which was matched exactly. Although it was possible to extend
ControlFlowPointcut to add support for pattern matching, it was a bit
cumbersome.
To address that, this commit introduces built-in pattern matching
support for method names in ControlFlowPointcut, analogous to the
pattern matching support in NameMatchMethodPointcut.
Specifically, a user can provide one or more method name patterns, and
the patterns will be matched against candidate method names using OR
semantics.
By default, the matching algorithm delegates to
PatternMatchUtils.simpleMatch(), but this can be overridden in
subclasses by overriding the new protected isMatch() method.
Closes gh-31435
This commit makes ControlFlowPointcut more open to subclasses by:
1. Making the ControlFlowPointcut#clazz field protected.
2. Making the ControlFlowPointcut#methodName field protected.
3. Introducing a protected incrementEvaluationCount() method.
Closes gh-27187
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
For equivalence, we only need to compare the preInstantiationPointcut
fields since they include the declaredPointcut fields. In addition, we
should not compare the aspectInstanceFactory fields since
LazySingletonAspectInstanceFactoryDecorator does not implement equals().
See gh-31238
This commit expands the scope of equality checks in the implementation
of equals() for PerTargetInstantiationModelPointcut to include all
fields instead of just the pointcut expression for the declared
pointcut.
See gh-31238
The introduction of AdvisedSupport.AdvisorKeyEntry in Spring Framework
6.0.10 resulted in a regression regarding caching of CGLIB generated
proxy classes. Specifically, equality checks for the proxy class cache
became based partially on identity rather than equivalence. For
example, if an ApplicationContext was configured to create a
class-based @Transactional proxy, a second attempt to create the
ApplicationContext resulted in a duplicate proxy class for the same
@Transactional component.
On the JVM this went unnoticed; however, when running Spring
integration tests within a native image, if a test made use of
@DirtiesContext, a second attempt to create the test
ApplicationContext resulted in an exception stating, "CGLIB runtime
enhancement not supported on native image." This is because Test AOT
processing only refreshes a test ApplicationContext once, and the
duplicate CGLIB proxy classes are only requested in subsequent
refreshes of the same ApplicationContext which means that duplicate
proxy classes are not tracked during AOT processing and consequently
not included in a native image.
This commit addresses this regression as follows.
- AdvisedSupport.AdvisorKeyEntry is now based on the toString()
representations of the ClassFilter and MethodMatcher in the
corresponding Pointcut instead of the filter's and matcher's
identities.
- Due to the above changes to AdvisorKeyEntry, ClassFilter and
MethodMatcher implementations are now required to implement equals(),
hashCode(), AND toString().
- Consequently, the following now include proper equals(), hashCode(),
and toString() implementations.
- CacheOperationSourcePointcut
- TransactionAttributeSourcePointcut
- PerTargetInstantiationModelPointcut
Closes gh-31238
This commit deprecates the various nullSafeHashCode methods taking array
types as they are superseded by Arrays.hashCode now. This means that
the now only remaining nullSafeHashCode method does not trigger a
warning only if the target type is not an array. At the same time, there
are multiple use of this method on several elements, handling the
accumulation of hash codes.
For that reason, this commit also introduces a nullSafeHash that takes
an array of elements. The only difference between Objects.hash is that
this method handles arrays.
The codebase has been reviewed to use any of those two methods when it
is possible.
Closes gh-29051
This commit allows a custom code fragment to provide the code to
create a bean without relying on ConstructorResolver. This is especially
important for use cases that derive from the default behaviour and
provide an instance supplier with the regular runtime scenario.
This is a breaking change for code fragments providing a custom
implementation of the related methods. As it turns out, almost all of
them did not need the Executable argument. Configuration class parsing
is the exception, where it needs to provide a different constructor in
the case of the proxy. To make this use case possible,
InstanceSupplierCodeGenerator has been made public.
Closes gh-31117
This commit adds support for Kotlin Coroutines to Spring AOP
by leveraging CoroutinesUtils#invokeSuspendingFunction in
AopUtils#invokeJoinpointUsingReflection to convert it to the
equivalent Publisher return value, like in other parts of Spring
Framework.
That allows method interceptors with Reactive support to process
related return values.
CglibAopProxy#processReturnType and JdkDynamicAopProxy#invoke
take care of the conversion from the Publisher return value
to Kotlin Coroutines.
Reactive transactional and HTTP service interface support
have been refined to leverage those new generic capabilities.
Closes gh-22462
Java 12 introduced java.lang.Class#componentType() as a shortcut for
getComponentType().
Since we started using arrayType() in fe5560400c, this commit switches
to componentType() for consistent API usage style.
Includes hashCode optimization in AbstractBeanFactoryBasedTargetSource.
Includes ThreadLocal naming fix in ThreadLocalTargetSource.

This commit refactors some AssertJ assertions into more idiomatic and
readable ones. Using the dedicated assertion instead of a generic one
will produce more meaningful error messages.
For instance, consider collection size:
```
// expected: 5 but was: 2
assertThat(collection.size()).equals(5);
// Expected size: 5 but was: 2 in: [1, 2]
assertThat(collection).hasSize(5);
```
Closes gh-30104
This commit picks up where the two previous commits left off.
Specifically, this commit:
- Removes the "severity=warning" configuration to ensure that violations
actually fail the build.
- Fixes regular expressions for suppressions by matching forward
slashes using `[\\/]` instead of `\/`.
- Moves the configuration for newly introduced checks to locations in
checkstyle.xml that align with the existing organization of that file.
- Renames the IDs for RegexpSinglelineJava checks from
javaDocPackageNonNullApiAnnotation/javaDocPackageNonNullFieldsAnnotation
to packageLevelNonNullApiAnnotation/packageLevelNonNullFieldsAnnotation,
respectively, since these checks are not related to Javadoc.
- Simplifies the null-safety annotation checks to match against
imported annotation types, which enforces consistency across
package-info.java files for the annotation declarations.
- Simplifies the RegEx for JavadocPackage suppressions to only exclude
packages not under src/main/java (vs src/main) and those in the
framework-docs module.
- Consistently suppresses all checks for the `asm`, `cglib`, `objenesis`,
and `javapoet` packages in spring-core.
- Adds explicit suppressions for null-safety annotations for the `lang`
package in spring-core.
- Adds explicit suppressions for null-safety annotations for the
`org.aopalliance` package in spring-aop.
- Revises the RegEx for null-safety annotation suppressions to only
exclude package-info.java files not under src/main/java and
additionally to exclude package-info.java files in the framework-docs
module as well as those in the spring-context-indexer,
spring-instrument, and spring-jcl modules.
- Adds all missing package-info.java files.
- Adds null-safety annotations to package-info.java files where
appropriate.

We no longer have any JDK 5 related limitations imposed on us as was
the case when MetadataAwareAspectInstanceFactory was introduced; however,
MetadataAwareAspectInstanceFactory will remain as a specialized
sub-interface of AspectInstanceFactory.
This commit makes sure that a `ScopedProxyFactoryBean` is exposed in the
container, rather than its underlying proxy. Previously, any lifecycle
method that the proxy target exposed were invoked in the container.
This is a complementary fix to gh-29335
This commit revisit BeanRegistrationCodeFragments to separate the
responsibility between the default implementation and the delegates. It
also reviews how customization are applied by improving the Javadoc and
the method name.
Closes gh-28865
This commit improves `TestCompiler` with a `with` function that allows
to customize a test compiler instance. Rather than `TestCompiler`
knowing about `TestGenerationContext`, the latter implements the
function so that it can be passed as is.
See gh-29175
This commit moves MethodReference to an interface with a default
implementation that relies on a MethodSpec. Such an arrangement avoid
the need of specifying attributes of the method such as whether it is
static or not.
The resolution of the invocation block now takes an
ArgumentCodeGenerator rather than the raw arguments. Doing so gives
the opportunity to create more flexible signatures.
See gh-29005
This commit updates GeneratedMethod and its underlying infrastructure
to be able to produce a MethodReference. This simplifies the need when
such a reference needs to be created manually and reuses more of what
MethodReference has to offer.
See gh-29005
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 harmonizes the package space by moving the TestCompiler
infrastructure from the now outdated "generator" package to "generate".
Closes gh-29082
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
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
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
Since gh-28781 is still open for team discussion, this commit removes
the `String...` variant for AopProxyUtils.completeJdkProxyInterfaces.
Depending on the outcome of gh-28781, this method may be reintroduced
in 6.0 M6.
