Since the Nashorn JavaScript engine was removed in Java 15, these tests
will never be run on a Java 17+ JDK which is required as of Spring
Framework 6.0.
See gh-27919
Since Spring Framework 5.3, BeanUtils.copyProperties() honors generics
in the source and target property types (see gh-24187); however, this
refinement of the contract was not properly documented prior to this
commit. In addition, the refinement can be a breaking change for users
who were relying on the previous unreliable behavior.
This commit therefore clarifies the behavior for generics support in
BeanUtils.copyProperties() and introduces a table of example matches
and mismatches when generics are involved.
Closes gh-27259
This commit updates InitDestroyBeanPostProcessor so that it contributes
init or destroy method names to the `RootBeanDefinition`. This is then
used by the generator to provide these methods to the optimized AOT
context.
Invocation of those init methods still happen using reflection so
dedicated hints are contributed for them.
Closes gh-28151
This commit makes sure that the response returned by coroutine handler
methods that return ResponseEntity<Flux> is unwrapped correctly.
Closes gh-27809
This commit updates InjectionGenerator to request a resolved attribute
with a dedicated type if multiple methods with the same name and the
same number of arguments exist. This was previously done already for
constructors and this commit harmonizes the algorithms to methods as
well
Closes gh-28154
This commit updates the generator to stop specifying a field type when
reflection is necessary, or when a reference to a field should be
retrieved as its name alone suffices.
This could trigger package protected issues if the field type is not
public.
See gh-28047
This commit fixes the algorithm used to analyze a generic parameter. If
a type in the generic signature is protected, the type is return rather
than the full signature. This makes sure that the appropriate package
is used. Previously, it would have incorrectly used the type of the
raw class.
Using a generic type for such a use case is wrong, and ProtectedElement
has been updated to expose a `Class` rather than a `ResolvableType`.
See gh-28030
This commit introduces a way to process a GenericApplicationContext
ahead of time. Components that can contribute in that phase are
invoked, and their contributions are recorded in the
GeneratedTypeContext.
This commit also expands BeanFactoryContribution so that it can exclude
bean definitions that are no longer required.
Closes gh-28150
This commit adds a way to refresh a GenericApplicationContext for ahead
of time processing: refreshForAotProcessing() processes the bean factory
up to a point where it is about to create bean instances.
MergedBeanDefinitionPostProcessor implementations are the only bean
post processors that are invoked during this phase.
Closes gh-28065
This commit adds a way for a BeanFactoryPostProcessor to participate to
AOT optimizations by contributing code that replaces its runtime
behaviour.
ConfigurationClassPostProcessor does implement this new interface and
computes a mapping of the ImportAware configuration classes. The mapping
is generated for latter reuse by ImportAwareAotBeanPostProcessor.
Closes gh-2811
Add a new unpublished `spring-core-test` module to support testing of
generated code. The module include a `TestCompiler` class which can be
used to dynamically compile generated Java code. It also include an
AssertJ friendly `SourceFile` class which uses qdox to provide targeted
assertions on specific parts of a generated source file.
See gh-28120
This commits adds an implementation that takes care of contributing
code for each bean definition in the bean factory, invoking
BeanRegistrationContributionProvider to determine the best candidate to
use.
Closes gh-28088
This commit introduces an infrastructure to contribute generated code
ahead of time to initialize a BeanFactory. Code and hints can be
contributed to a BeanFactorInitialization, with the ability to write to
other packages if necessary.
An implementation of that new interface that registers a BeanDefinition
is also included in this commit. It delegates to a
BeanInstantiationGenerator for geenerating the instance supplier that
creates the bean instance.
For corner cases, a BeanRegistrationContributionProvider can be
implemented. It allows to return a custom BeanFactoryContribution for
a particualr bean definition. This usually uses the default
implementation with a custom instance supplier.
Note that this commit adds an temporary executable resolution that is
meant to be replaced by the use of ConstructorResolver
See gh-28088
This commit extracts the logic of resolving a merged bean definition for
an inner bean to a public method so that other components can reuse it.
Closes gh-28093
This commit adds an infrastructure for code that generate types with the
need to write to another package if privileged access is required. An
abstraction around types where methods can be easily added is also
available as part of this commit.
Closes gh-28149
This commit harmonizes the use of the "generate" keyword for anything
related to code generation. Previously, there was a mix of "generate"
and "write."
See gh-28047
This commit updates AotContributingBeanPostProcessor so that it
explicitly extends from PriorityOrdered. This makes it more apparent
that AOT contributing bean post processors are meant to be invoked
early with the regular runtime, and shouldn't be post-processed
themselves.
See gh-28047
This commit polishes the contribution model where an AOT contributing
bean post processor can return a contribution, rather than a
contributor. This makes it easier to return `null` if no contribution
can be produced now that it is named this way.
