Update `ApplicationContextAotGenerator` so that it can generate class
names based on a `target` class and using the ID of the application
context. Prior to this commit, the generated class name was always
`__.BeanFactoryRegistrations`.
Closes gh-28565
This commit adds a central utility to figure out if the application
must run with Ahead-Of-Time optimizations. This is mandatory for running
in a native image but can be selected on the JVM using the
"spring.aot.enabled" property.
This commit also introduces a utility that can be used to initialize a
context with generated artifacts. This represents the runtime
counterpart of ApplicationContextAotGenerator.
Closes gh-28474
Prior to this commit, the hints conditions were only supported for the
`TypeHint` case. GraalVM generally expanded this concept to all hints
and we should do the same.
Right now, only the `typeReachable` condition is available but we should
design for possible future additions.
This commit introduces a new `ConditionalHint` contract implemented by
all hints compatible with this approach. The condition information is
also used in all configuration writers as a result.
Closes gh-28126
This commit adds a `@Reflective` annotation that can be used to declare
that the annotated element requires reflection at runtime. By default,
the annotated element is exposed but this can be customized by
specifying a dedicated `ReflectiveProcessor`.
Closes gh-28469
A static nested class does not keep an implicit reference to its
enclosing instance.
This prevents a common cause of memory leaks and uses less memory per
instance of the class.
Closes gh-28433
Prior to this commit, we could only contribute `RuntimeHints` through
two mechanisms:
* `AotContributingBeanFactoryPostProcessor`, consdering the entire
`BeanFactory` and designed for contributing both code and hints.
* `AotContributingBeanPostProcessor`, consdering beans one by one, but
also designed for contributing both code and hints.
There are cases where libraries and applications want to contribute
`RuntimeHints` only, in a more static fashion: a dependency being
present, or a piece of infrastructure being considered by the
application context are good enough signals to contribute hints about
resources or reflection.
This commit adds the `RuntimeHintsRegistrar` contract for these cases.
Implementations can be declared as `spring.factories` and they will be
processed as soon as they're detected on the classpath. They can also be
declared with `@ImportRuntimeHints` and they will be processed if the
annotated bean definition is considered in the application context.
This annotation should be mainly used on configuration classes and on
bean methods.
```
@Configuration
@ImportRuntimeHints(CustomRuntimeHintsRegistrar.class)
public class MyConfiguration {
@Bean
@ImportRuntimeHints(OtherRuntimeHintsRegistrar.class)
public MyBean myBean() {
//...
}
}
```
Closes gh-28160
This commit removes Spring's custom NestedIOException and replaces its
usage with the standard IOException which has supported a root cause
since Java 6.
Closes gh-28198
With a Java 8 baseline in place for quite some time now, it no longer
makes sense to refer to features such as annotations as "Java 5
annotations".
This commit also removes old `Tiger*Tests` classes, thereby avoiding
duplicate execution of various tests.
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
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 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
Before this commit, CronField.Type::rollForward added temporal units
to reach the higher order field. This caused issues with DST, where
the added amount of hours was either too small or too large.
This commit refactors the implementation so that it now adds one to the
higher order field, and reset the current field to the minimum value.
Closes gh-28095
SocketUtils was introduced in Spring Framework 4.0, primarily to assist
in writing integration tests which start an external server on an
available random port. However, these utilities make no guarantee about
the subsequent availability of a given port and are therefore
unreliable. Instead of using SocketUtils to find an available local
port for a server, it is recommended that users rely on a server's
ability to start on a random port that it selects or is assigned by the
operating system. To interact with that server, the user should query
the server for the port it is currently using.
SocketUtils is now deprecated in 5.3.16 and will be removed in 6.0.
Closes gh-28052
Prior to this commit, if AOP proxy generation was configured with
proxyTargetClass=true (which is the default behavior in recent versions
of Spring Boot), beans implemented as lambda expressions or method
references could not be proxied with CGLIB on Java 16 or higher without
specifying `--add-opens java.base/java.lang=ALL-UNNAMED`.
This commit addresses this shortcoming by ensuring that beans
implemented as lambda expressions or method references are always
proxied using a JDK dynamic proxy even if proxyTargetClass=true.
Closes gh-27971
Prior to this commit, the QuartzCronField::weekdayNearestTo would elapse
until the next month before checking if the current day matched.
After this commit, the current day is checked before we elapse until
the next month.
