This commit is a best effort attempt at identifying the members that
code generation invokes and might be deprecated. It introduces
a CodeWarnings helper class that records warnings, with special
handling for `@Deprecated`.

Prior to this commit, the bean definition properties code generator
would register hints for invoking the setter methods of registered
property values defined for the bean definition.
The internal algorithm is also reflecting on the Field to discover
annotations. Doing so actually calls `getDeclaredFields` to iterate on
the available fields. This is done recursively up the type hierarchy
until the field is found.
This commit registers the required reflection metadata.
Closes gh-31390
This commit removes the previously introduced reflection hints that were
working around known issues in GraalVM.
Spring Framework 6.1 will require recent maintenance versions of GraalVM
and should not contribute such hints anymore.
Closes gh-30394
Prior to this commit, the bean registration AOT contributions would
register introspection and invocation hints on both declared and public
methods for bean types. The bean introspection algorithm also looks at
default methods implemented by interfaces when collecting bean property
information.
This commit ensures that introspection hints are registered for all
implemented interfaces when registering beans.
Closes gh-31350
Prior to this commit, the `BeanRegistrationsAotContribution` would only
contribute introspection hints for declared methods. This does not cover
inherited public methods.
This commit adds the missing hint on public methods.
Fixes gh-31293
Prior to this commit, `DisposableBeanAdapter` supported reactive bean
destroy methods by detected if `Publisher` is available on the
classpath. The AOT engine did not contribute a reflection hint for this
call.
This commit ensures that this reflection hint is registered in all
cases, even if there are no destroy methods detected on beans.
Fixes gh-31278
This commit adds reflection hints for `jakarta.inject.Provider` and
ensures that hints are always contributed even if jakarta classes are
not on the classpath.
Fixes gh-31259
This commit reviews when an AOT-generated bean definition defines a
beanClass or targetType. Previously, a beanClass was not consistently
set which could lead to issues.
Closes gh-31242
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types as they are superseded by Arrays.hashCode now.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.
Closes gh-29051
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 adds support for Kotlin value classes annotated
with @JvmInline to BeanUtils#findPrimaryConstructor.
This is only the first step, more refinements are expected
to be needed to achieve a comprehensive support of Kotlin
values classes in Spring Framework.
Closes gh-28638
Java 12 introduced java.lang.Class#componentType() as a shortcut for
getComponentType().
Since we started using arrayType() in fe5560400c, this commit switches
to componentType() for consistent API usage style.
