This commit reverts the deprecation of CommandLinePropertySource and
SimpleCommandLinePropertySource, since we have discovered that Spring
Boot actively uses SimpleCommandLinePropertySource in
org.springframework.boot.SpringApplication.
Closes gh-31207
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types as they are superseded by Arrays.hashCode now.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.

AnnotationBeanNameGenerator was written before the introduction of the
MergedAnnotations API and therefore heavily relies on the
AnnotationMetadata abstraction and various helper methods for ASM
compatibility.
However, recent work on determineBeanNameFromAnnotation() has made it
apparent that we should use the MergedAnnotations API directly in
AnnotationBeanNameGenerator where feasible in order to avoid
unnecessary, repeated iterations/streams over the same annotation
metadata.
Closes gh-31203
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 prints a log message at debug level without
a stacktrace for TypeNotPresentException and uses
warn level instead of error level for other exceptions
since the processing of such bean will just be skipped.
Closes gh-31147
When use of the deprecated feature is detected, a WARNING log message
will be generated analogous to the following.
WARN o.s.c.a.AnnotationBeanNameGenerator - Support for convention-based
stereotype names is deprecated and will be removed in a future version
of the framework. Please annotate the 'value' attribute in
@org.springframework.context.annotation.AnnotationBeanNameGeneratorTests$ConventionBasedComponent1
with @AliasFor(annotation=Component.class) to declare an explicit alias
for @Component's 'value' attribute.
See gh-31089
Closes gh-31093
This commit builds on the recently added support for using @AliasFor to
override the `value` attribute in `@Component, and allows a custom
component name to be specified in both @ControllerAdvice and
@RestControllerAdvice via new `name` attributes.
See gh-31089
Closes gh-21108
Although gh-20615 introduced the use of @AliasFor for @Component(value) in the built-in
stereotype annotations (@Service, @Controller, @Repository, @Configuration, and
@RestController), prior to this commit the framework did not actually rely on @AliasFor
support when looking up a component name via stereotype annotations. Rather, the
framework had custom annotation parsing logic in
AnnotationBeanNameGenerator#determineBeanNameFromAnnotation() which effectively ignored
explicit annotation attribute overrides configured via @AliasFor.
This commit revises AnnotationBeanNameGenerator#determineBeanNameFromAnnotation() so that
it first looks up @Component stereotype names using @AliasFor semantics before falling
back to the "convention-based" component name lookup strategy.
Consequently, the name of the annotation attribute that is used to specify the bean name
is no longer required to be `value`, and custom stereotype annotations can now declare an
attribute with a different name (such as `name`) and annotate that attribute with
`@AliasFor(annotation = Component.class, attribute = "value")`.
Closes gh-31089
This commit reinstates support for the legacy JSR-250
@javax.annotation.ManagedBean and JSR-330 @javax.inject.Named
annotations with regard to component name lookups and component
scanning.
