Prior to this commit, ConfigurationClass implemented equals(),
hashCode(), and toString(), but BeanMethod did not.
This commit introduces equals(), hashCode(), and toString()
implementations in BeanMethod for consistency with ConfigurationClass
to make it possible to use BeanMethod instances to index additional
metadata as well.
In order to properly implement equals() in BeanMethod, the method
argument types are required, but these are not directly available in
BeanMethod. However, they are available via ASM when processing @Bean
methods. This commit therefore implements equals(), hashCode(), and
toString() in SimpleMethodMetadata which BeanMethod delegates to.
For completeness, this commit also implements equals(), hashCode(), and
toString() in StandardClassMetadata, StandardMethodMetadata, and
SimpleAnnotationMetadata.
Closes gh-27076
This commit improves the Javadoc regarding transactional semantics for
@TransactionalEventListener methods invoked in the AFTER_COMMIT,
AFTER_ROLLBACK, or AFTER_COMPLETION phase. Specifically, the
documentation now points out that interactions with the underlying
transactional resource will not be committed in those phases.
Closes gh-26974
Prior to this commit, evaluating validation hints for
@javax.validation.Valid caused exceptions being raised when getting the
value of this annotation, which does not exist. Bypassing
AnnotationUtils.getValue() in those cases can improve performance by
avoiding the cost incurred by raising exceptions.
See gh-26787
Prior to this commit, two tests for exception handling regarding
@DateTimeFormat processing only passed on Java 8. This is due to the
fact that the toString() implementation for annotations changed in Java
9. Specifically, the representation for arrays changed from [] to {},
and strings are enclosed in double quotes beginning with Java 9.
This commit ensures that the affected @DateTimeFormat tests pass on
Java 9+, by making the assertions more lenient regarding toString()
output for annotations.

The support for fallback parsing patterns in @DateTimeFormat introduced
in gh-20292 introduced a regression in that the original cause of the
parsing exception was no longer retained.
gh-26777 addressed that regression for `java.time` support; whereas,
this commit addresses that regression for legacy Date types.
This commit ensures that the original ParseException is set as the
cause for any newly created ParseException, thereby retaining the
original exception as the root cause.

Prior to this commit, @DateTimeFormat only supported a single format
for parsing date time values via the style, iso, and pattern attributes.
This commit introduces a new fallbackPatterns attribute that can be
used to configure multiple fallback patterns for parsing date time
values. This allows applications to accept multiple input formats for
date time values.
For example, if you wish to use the ISO date format for parsing and
printing but allow for lenient parsing of user input for various
additional date formats, you could annotate a field or method parameter
with configuration similar to the following.
@DateTimeFormat(
iso = ISO.DATE,
fallbackPatterns = { "M/d/yy", "dd.MM.yyyy" }
)
Closes gh-20292
Since Spring Framework 5.2, the LoadTimeWeaver no longer weaves bean
classes annotated with @Component. This is a regression caused by the
changes in 40c62139ae, stemming from the fact that any class annotated
or meta-annotated with @Component is considered to be a candidate
configuration class in 'configuration lite' mode (i.e., a class without
the @Configuration annotation and without any @Bean methods) and
therefore now has its class eagerly loaded. This results in the class
being loaded before the LoadTimeWeaver has a chance to weave it.
This commit fixes this regression by explicitly avoiding eager class
loading for any 'lite' @Configuration or @Component class without @Bean
methods.

Prior to this commit, the `SimpleApplicationEventMulticaster` would be
instrumented with the `ApplicationStartup` and start/stop events for
invoking event listeners (`spring.event.invoke-listener`).
This feature was already limited to single-threaded event publishers,
but is still flawed since several types of events can happen
concurrently. Due to the single-threaded nature of the startup sequence,
our implementation should not produce startup events concurrently.
This can cause issues like gh-26057, where concurrent events lead to
inconcistencies when tracking parent/child relationships.
This commit removes the `spring.event.invoke-listener` startup event as
a result.
Fixes gh-26057
Adds a static INSTANCE to FullyQualifiedAnnotationBeanNameGenerator,

Issues gh-25038 and gh-25618 collectively introduced a regression for
thread-scoped and transaction-scoped beans.
For example, given a thread-scoped bean X that depends on another
thread-scoped bean Y, if the names of the beans (when used as map keys)
end up in the same bucket within a ConcurrentHashMap AND an attempt is
made to retrieve bean X from the ApplicationContext prior to retrieving
bean Y, then the use of Map::computeIfAbsent in SimpleThreadScope
results in recursive access to the same internal bucket in the map.
On Java 8, that scenario simply hangs. On Java 9 and higher,
ConcurrentHashMap throws an IllegalStateException pointing out that a
"Recursive update" was attempted.
In light of these findings, we are reverting the changes made to
SimpleThreadScope and SimpleTransactionScope in commits 50a4fdac6e and
148dc95eb1.
Closes gh-25801
Prior to this commit, the `GenericApplicationContext` configured the
`AppliationStartup` on the `BeanFactory` only right before refreshing it.
Delaying this has no purpose and we should instead configure it as soon
as possible by overriding the setter method.
Closes gh-25718
PR gh-25038 introduced regressions in SimpleThreadScope and
SimpleTransactionScope in Spring Framework 5.2.7. Specifically, if a
thread-scoped or transaction-scoped bean has a dependency on another
thread-scoped or transaction-scoped bean, respectively, a
ConcurrentModificationException will be thrown on Java 11 or higher.
The reason is that Java 11 introduced a check for concurrent
modification in java.util.HashMap's computeIfAbsent() implementation,
and such a modification can occur when a thread-scoped bean is being
created in order to satisfy a dependency of another thread-scoped bean
that is currently being created.
This commit fixes these regressions by switching from HashMap to
ConcurrentHashMap for the instance maps in SimpleThreadScope and
SimpleTransactionScope.

This commit removes support for a standalone "L" in the
day-of-week of a cron expression, which used a locale-dependent
API to determine what the last day of the week is (Saturday or
Sunday ?).
Alternatively, we could have implement this in the exact way as Quartz
has done (i.e. treat the "L" like "SAT"), but we opted not to do that,
as having an explicit SAT or SUN is much clearer.
This commit makes sure that in CronExpression, the asterisk is only used
in a range field, and is not surrounded by unexpected characters.

This commit adds a new `StartupStep` interface and its factory
`ApplicationStartup`. Such steps are created, tagged with metadata and
thir execution time can be recorded - in order to collect metrics about
the application startup.
The default implementation is a "no-op" variant and has no side-effect.
Other implementations can record and collect events in a dedicated
metrics system or profiling tools. We provide here an implementation for
recording and storing steps with Java Flight Recorder.
This commit also instruments the Spring application context to gather
metrics about various phases of the application context, such as:
* context refresh phase
* bean definition registry post-processing
* bean factory post-processing
* beans instantiation and post-processing
Third part libraries involved in the Spring application context can
reuse the same infrastructure to record similar metrics.

Prior to this commit, if a BeanNameAutoProxyCreator was configured with
a custom TargetSourceCreator, the TargetSourceCreator was applied to
all beans in the ApplicationContext. Thus, the list of supported
beanNames was effectively ignored when applying any
TargetSourceCreator. Consequently, if a TargetSourceCreator returned a
non-null TargetSource for a given bean, the BeanNameAutoProxyCreator
proxied the bean even if the bean name had not been configured in the
beanNames list.
This commit addresses this issue by ensuring that a custom
TargetSourceCreator is only applied to beans whose names match the
configured beanNames list in a BeanNameAutoProxyCreator.

Prior to this commit, the testTestLazyConnectionToRemote() method in
MBeanClientInterceptorTests expected an exception to be thrown while
attempting to access the state of a proxied MBean after the MBeanServer
had been shutdown; however, the test occasionally failed if the server
had not been properly shutdown.
Since an attempt to wait on the server to shutdown proved not to be
consistently helpful in this scenario, we are entirely removing this
check from the test.
Spring Framework 5.0 introduced a regression in ASM-based annotation
processing. Specifically, nested annotations were no longer supported,
and component scanning resulted in an exception if a candidate
component was annotated with an annotation that contained nested
annotations.
This commit fixes this regression by introducing special handling in
AnnotationTypeMapping that supports extracting values from objects of
type TypeMappedAnnotation when necessary.

This commit updates BeanFactoryAwareGeneratorStrategy to extend
ClassLoaderAwareGeneratorStrategy in order to avoid duplication of the
common generate() implementation.
Closes gh-24396
Prior to this commit, Spring offered two top-level implementations of
the BeanNameGenerator strategy: DefaultBeanNameGenerator and
AnnotationBeanNameGenerator. The latter is used as the default bean
name generator for beans picked up via component scanning. In a typical
application, this strategy works well; however, if multiple component
scanned beans have the same simple class name (i.e., identical names
ignoring the package), a BeanDefinitionStoreException is thrown.
To address such naming conflicts, users of Spring have had to implement
a custom BeanNameGenerator based on the fully qualified class name of
such components.
Similar conflicts can arise with components registered via
configuration class imports (i.e., via @Import), and
ConfigurationClassPostProcessor addresses this via an anonymous inner
class that extends AnnotationBeanNameGenerator but falls back to using
the fully qualified class name if an explicit bean name is not provided
via an annotation.
This commit extracts the implementation of
ConfigurationClassPostProcessor's internal BeanNameGenerator into a new
top-level FullyQualifiedAnnotationBeanNameGenerator class that can be
used to disambiguate between same-named components residing in
different packages that are picked up via component scanning. This bean
name generator can be configured via @ComponentScan's nameGenerator
attribute.

Prior to this commit, InstantFormatter was able to properly serialize
an Instant that is far in the future (or in the past), but it could not

and also introduces tests for InstantFormatter.

Currently, if you have an optional event listener (via a @Bean method returning `null`)
this causes the event multicaster to explode violently. Now, we just safely skip it.
This commit refactors several tests to use SocketUtils to find an

start an MBeanServer for the particular test using that port.
This commit also makes other changes to MBeanServer related tests in an
effort to make them more robust when executed concurrently.
Closes gh-23699
Prior to this commit, the `DateFormatterRegistrar` would register the
annotation-based formatter before the pattern-based formatter. This
would create an issue when an application tries to convert a `String` to
an annotated `@DateTimeFormat Date`: since the converters are considered
in reversed order of registration in
`GenericConversionServicei#ConvertersForPair`, the pattern-based variant
would always be considered before the annotation-based variant,
overriding the developer's opinion.
This commit aligns the `DateFormatterRegistrar` with the
`DateTimeFormatterRegistrar` and registers the annotation-based variant
last.

Prior to this commit, a lot of work had been done to prevent improper
use of testing Framework APIs throughout the codebase; however, there
were still some loopholes.
This commit addresses these loopholes by introducing additional
Checkstyle rules (and modifying existing rules) to prevent improper use
of testing framework APIs in production code as well as in test code.
- Checkstyle rules for banned imports have been refactored into
multiple rules specific to JUnit 3, JUnit 4, JUnit Jupiter, and
TestNG.
- Accidental usage of org.junit.Assume has been switched to
org.junit.jupiter.api.Assumptions.
- All test classes now reside under org.springframework packages.
- All test classes (including abstract test classes) now conform to the
`*Tests` naming convention.
- As an added bonus, tests in the renamed
ScenariosForSpringSecurityExpressionTests are now included in the
build.
- Dead JUnit 4 parameterized code has been removed from
DefaultServerWebExchangeCheckNotModifiedTests.

MergedAnnotations provides 'from' variants with RepeatableContainers but without AnnotationFilter argument now, avoiding the need to refer to AnnotationFilter.PLAIN as a default at call sites.
Prior to this commit, the Spring Framework build would partially use the

Some versions are overridden in specific modules for
backwards-compatibility reasons or extended support.
This commit also adds the Gradle versions plugin that checks for
dependency upgrades in artifact repositories and produces a report; you
can use the following:

Due to a bug (or "unintentional feature") in JUnit 4, overridden test
and lifecycle methods not annotated with @Test, @Before, @After, etc.
are still executed as test methods and lifecycle methods; however,
JUnit Jupiter does not support that. Thus, prior to this commit, some
overridden test and lifecycle methods were no longer executed after the
migration from JUnit 4 to JUnit Jupiter.
This commit addresses this issue for such known use cases, but there
are likely other such use cases within Spring's test suite.

* internal modules, such as the BOM, our coroutines support and our
integration-tests
With this change, we're strealining the project configuration for all
spring modules and only applying plugins when needed (typically our
kotlin support).
