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
Update the logic in `AbstractBeanFactory` so that caches from merged
bean definitions remain whenever possible.
Prior to this commit, all merged bean definitions would be completely
removed after bean post processing in case a processor changed the bean
type. It's fairly unlikely these days that the bean type will actually
change, so instead we now compare a subset of the old cached properties
against the newly created definition. Only if key properties have
changed do we now discard the older cached values.
Closes gh-23336
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
This covers ApplicationListener generics in factory method return types in particular but also allows for programmatic setTargetType hints.
Closes gh-23178
Prior to this commit, AbstractAutowireCapableBeanFactory's
invokeCustomInitMethod() method invoked
ClassUtils.getInterfaceMethodIfPossible() even if the security manager
was not being used.
This commit ensures that getInterfaceMethodIfPossible() is only invoked
if the security manager is used.
Closes gh-23323
Prior to this commit, there was some ambiguity surrounding semantics
for @Autowired constructors and `required = true`, especially for
multiple @Autowired constructors.
This commit improves the documentation in the Javadoc for @Autowired as
well as in the reference manual.
Closes gh-23263
Beginning with Spring Framework 5.0, non-null checks for the
requiredType in the following methods were inadvertently removed with
the internal switch to ResolvableType.forRawClass(requiredType).
- BeanFactory.getBean(Class<T>, Object...)
- BeanFactory.getBeanProvider(Class<T>)
- AutowireCapableBeanFactory.resolveNamedBean(Class<T>)
This commit restores those non-null checks.
Closes gh-23045
Deprecate the public `StandardMetadata` constructors to make it clearer
that these classes should not be instantiated directly. A new
`AnnotationMetadata.introspect` factory method has been added which
can now be used to obtain instances.
This change will allow use to make the constructors package private
and drop the `nestedAnnotationsAsMap` parameter in a future release.
Closes gh-22906
