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
properly deserialize it, because in such scenarios an ISO-formatted
Instant starts with a +/- sign.
This commit fixes this issue, while maintaining the previous contract,
and also introduces tests for InstantFormatter.
Closes gh-23895
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.
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
Prior to this commit, the name of the Thread registered via
ConfigurableApplicationContext#registerShutdownHook() was the generic,
default thread name ("Thread-#"). That made it difficult to discern
which executing thread was the Spring ApplicationContext shutdown hook.
This commit improves diagnostics by setting the thread name of the
ApplicationContext shutdown hook to "SpringContextShutdownHook".
Closes gh-23670
This commit removes the duplicated CRON_DISABLED constant value from
@Scheuled and simply refers to the ScheduledTaskRegistrar.CRON_DISABLED
constant.
This avoids a potential package cycle by ensuring that the `annotation`
package depends on the `config` package but not the other way around.
See gh-23568
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
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.
This commit avoids unnecessary processing in the implementation of
postProcessBeforeInitialization() in ApplicationContextAwareProcessor
by immediately returning the supplied bean if it does not meet the
requirements for further processing.
Closes gh-23435
Update `ListableBeanFactory` and `BeanFactoryUtils` to add the missing
`getBeanNamesForType` methods that accept a `ResolvableType` rather
than a `Class`.
This completes the work started in 778a01943b.
Closes gh-23335
