This commit expands GeneratedClassHandler to allow invocation of
declared fields and methods. Generated proxies have a number of
internal fields and methods that are invoked via reflection.
See gh-28954
This commit updates ApplicationContextAotGenerator to register a
handler that process Cglib generated classes. The handler registers
such classes to the GeneratedFiles and provide a hint so that it
can be instantiated using reflection.
Closes gh-28954
Includes runtime storing of generated classes to a directory specified by the "cglib.generatedClasses" system property. Avoids lazy CGLIB fast-class generation and replaces generated Enhancer and MethodWrapper key classes with equivalent record types. Introduces support for early type determination in InstantiationStrategy, AopProxy and SmartInstantiationAwareBeanPostProcessor - in order to trigger CGLIB class generation in refreshForAotProcessing (through early determineBeanType calls for bean definitions).
Closes gh-28115
This commit updates refresh for AOT processing so that the configuration
is frozen before invoking MergedBeanDefinitionPostProcessor instances.
This makes sure that post-processed MergedBeanDefinitions are kept in
cache and not lost if a component attempts to clear the metadata cache.
Closes gh-28941
This commit updates ImportAwareAotBeanPostProcessor to be priority
ordered, with the same order as its original BeanPostProcessor. This
makes sure that infrastructure beans can be post-processed if
necessary
See gh-28915
This commit adapts the generated code for handling ImportAware to
register a bean definition rather than adding the BeanPostProcessor
directly on the beanFactory. The previous arrangement put the
post processor handling import aware callbacks first on the list,
leading to inconsistent callback orders.
Tests have been adapted to validate this exact scenario.
Closes gh-28915
Add an `AotServices` class to replace `AotFactoriesLoader`. The
replacement class allow instances to be loaded from just the
`aot.factories` file if required. It also retains a link to the bean
names so that a `findByBeanName(...)` method can be provided.
See gh-28833
This commit deprecates ListenableFuture in favor of CompletableFuture.
ListenableFuture was introduced in Spring Framework 4.0, when
CompletableFuture was not yet available. Spring now requires JDK 17, so
having our own type no longer seems necessary.
Major changes in this commit include:
- Deprecation of ListenableFuture and related types
(ListenableFutureCallback, SettableListenableFuture, etc.)
- Deprecation of AsyncListenableTaskExecutor in favor of default methods
in AsyncTaskExecutor (submitCompletable).
- AsyncHandlerMethodReturnValueHandler now has toCompletableFuture
instead of toListenableFuture.
- WebSocketClient now has execute methods, which do the same as
doHandshake, but return CompletableFutures (cf. the reactive
WebSocketClient).
All other changes
- add an overloaded method that takes a CompletableFuture parameter
instead of ListenableFuture, and/or
- add a method with a 'Async' suffix that returns a CompletableFuture
instead of a ListenableFuture (connectAsync, sendAsync).
Closes gh-27780
This commit registers the MergedBeanDefinitionPostProcessor instances
on the BeanFactory processed for AOT purposes. This allows beans that
are created at build-time to be post-processed for low-level needs such
as initialization and autowiring.
Closes gh-28777
Migrate all AOT tests to make use of `GeneratedClasses` rather than
directly generating Java files. This commit also refines and polishes
AOT APIs to being greater consistency.
Specifically:
- The `MethodGenerator` interface has been removed in favor of
working directly with `GeneratedMethods`.
- The visibility of several constructors and methods has been
reduced to package-private.
- The `using(...)` and `builder` methods have been removed in
favor of setting the `Consumer` callbacks directly as
constructor arguments.
- Variable names for builders are now named `type` or `method`
depending on what they're building.
Closes gh-28831
Prior to this commit, when users wished to register proxy hints for a
Spring AOP JDK dynamic proxy, they were required to explicitly specify
SpringProxy, Advised, and DecoratingProxy along with user interfaces.
This commit simplifies hint registration for Spring AOP proxies by
introducing two completeJdkProxyInterfaces() methods in AopProxyUtils,
one that accepts strings and one that accepts classes that represent
the user-specified interfaces implemented the user component to be
proxied. The SpringProxy, Advised, and DecoratingProxy interfaces are
appended to the user-specified interfaces and returned as the complete
set of interfaces that the proxy will implement.
Closes gh-28745
This commit deprecates all methods in org.springframework.scheduling
that use
- Date, in favor of variants that take an Instant.
- long & TimeUnit, in favor of variants that take a Duration.
Closes: gh-28714
When the ProtocolResolver SPI was introduced in Spring Framework 4.3,
support for protocol resolvers was added in DefaultResourceLoader's
getResource() implementation; however, GenericApplicationContext's
overridden getResource() implementation was not updated accordingly.
Prior to this commit, if a GenericApplicationContext was configured
with a custom ResourceLoader, registered protocol resolvers were
ignored.
This commit ensures that protocol resolvers are honored in
GenericApplicationContext even if a custom ResourceLoader is used.
Closes gh-28703
This commit moves the responsibility of naming classes to the
GenerationContext. This was already largely the case before, except that
the concept of a "mainTarget" and "featureNamePrefix" was specific
to bean factory initialization contributors.
ClassNameGenerator should now be instantiated with a default target
and an optional feature name prefix. As a result, it does no longer
generate class names in the "__" package.
GeneratedClasses can now provide a new, unique, GeneratedClass or
offer a container for retrieving the same GeneratedClass based on an
identifier. This lets all contributors use this facility rather than
creating JavaFile manually. This also means that ClassNameGenerator
is no longer exposed.
Because the naming conventions are now part of the GenerationContext, it
is required to be able to retrieve a specialized version of it if a
code generation round needs to use different naming conventions. A new
withName method has been added to that effect.
Closes gh-28585
Since LoggingCacheErrorHandler was only recently introduced in 5.3.16,
we have decided to completely revise its internals (protected API) in
5.3.x while retaining the current public API.
Specifically, this commit:
- introduces protected getLogger() and isLogStackTraces() methods to
improve extensibility
- revises logCacheError() to accept a Supplier<String> for lazy
resolution of error messages
Closes gh-28672
See gh-28670, gh-28648
At present, creating a LoggingCacheErrorHandler that logs stack traces
also requires supplying the logger to be used. This might be
inconvenient for some users, as it requires usage of the Commons
Logging API.
This commit simplifies creation of such as LoggingCacheErrorHandler
instance by adding a constructor that only accepts a boolean flag
indicating whether to log stack traces.
Closes gh-28670
Includes deprecation of NestedServletException, whereas NestedCheckedException and NestedRuntimeException remain as base classes with several convenience methods.
Closes gh-25162
We use Grafana to monitor our app via Spring's JMX exporter, and we
think it could be interesting to have at least the current queue size
for this purpose since the queue size directly affects the app memory
load. Having the queue capacity seems also interesting to set up
triggers whose values are calculated based on the maximum capacity of
the queue.
This commit introduces new getCurrentQueueSize() and getQueueCapacity()
methods in ThreadPoolTaskExecutor.
See gh-28583
Refine the class name logic so that the name is passed in rather
than using `ApplicationContext.getId()`. Also propagate the name
so that the generated classes use it.
See gh-28565
