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
available port, compose a custom JMX service URL using that port, and
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.

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.
Closes gh-23893
Allow `ImportBeanDefinitionRegistrar`, `ImportSelector`,
`DeferredImportSelector.Group` and `TypeFilter` to use constructor
parameters as an alternative to `*Aware` callbacks.
In order to remain backwards compatible, injection only occurs
when there is a single constructor with one or more parameters.
The following parameter types are supported:
* `Environment`
* `BeanFactory`
* `ClassLoader`
* `ResourceLoader`
In order to keep the algorithm simple, subclass parameter types are
not supported. For example, you cannot use `ConfigurableEnvironment`
instead of `Environment`.
Closes gh-23637
Prior to this commit, support was provided for disabling cron jobs
configured with an explicit "-" cron expression. However, the "-"
expression was only supported when supplied via the @Scheduled
annotation.
This commit adds support for disabling cron jobs configured with the
"-" cron expression when a cron job is registered via the
addCronTask(Runnable, String) method in the ScheduledTaskRegistrar
supplied to a SchedulingConfigurer.
Closes gh-23568
Previously, some tests in spring-context wrote a file named jmx.log
into spring-context/. This led to the file being included in the
sources of the Checkstyle NoHTTP Gradle task, breaking that task's
UP-TO-DATE checks and causing it to execute unnecessarily.
This commit updates the tests to write the jmx.log file beneath
spring-context/build/ so that it is not included in the sources of the
Checkstyle NoHTTP task.
Closes gh-23623
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.
Closes gh-22962
This commit prepends "[{index}] " to all custom display names
configured via @ParameterizedTest.
This provides better diagnostics between the "technical names" reported
on the CI server vs. the "display names" reported within a developer's
IDE.

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.

Update `AbstractAutowireCapableBeanFactory.getTypeForFactoryBean` to
use fallback to `determineTargetType` if the factory bean definition
does not have a resolved class.
This is required for the case where a `@Configuration` class is picked
up via component scanning and has a bean type that has not yet been
resolved.
Closes gh-23338
Update `getTypeForFactoryBean` detection so that a bean definition
attribute can be used to supply the result. This commit allows projects
such as Spring Data to provide the result that would be supplied by
`getObjectType` early so that we don't need to initialize the
`FactoryBean` unnecessarily.
Closes gh-23338
Update the `FactoryBean` type prediction logic (primarily in the
`DefaultListableBeanFactory`) so that generic type information is
considered when calling `getBeanNamesForType` on a non-frozen
configuration.
Calling `getBeanNamesForType` with `allowEagerInit` disabled will now
detect `FactoryBean` variants as long as generic type information is
available in either the class or the factory method return type.
Closes gh-23338
This covers ApplicationListener generics in factory method return types in particular but also allows for programmatic setTargetType hints.
Closes gh-23178
Update `FormatterRegistry` with `addPrinter` and `addParser` methods
that can be used to register Printer or Parser implementations in a
similar way to the existing `addFormatter` method.
Closes gh-23110
