Previously we had restored the whitespace for *.aj files in 6888a6f28
to avoid a but in aspectj.
We have updated to the latest version of apsectj and restored the
changes in commit 6888a6f28 which included a significant cleanup of
whitespace.
Issue: SPR-10208
Effectively, AbstractTransactionAspect got refactored into around advice, reusing former TransactionInterceptor code which now lives in slightly generalized form in TransactionAspectSupport, and using a workaround for rethrowing checked exceptions.
Issue: SPR-9268
Allow @Cachable, @CachePut and equivalent XML configuration to provide
a SpEL expression that can be used to veto putting an item into the
cache. Unlike 'condition' the 'unless' parameter is evaluated after
the method has been called and can therefore reference the #result.
For example:
@Cacheable(value="book",
condition="#name.length < 32",
unless="#result.hardback")
This commit also allows #result to be referenced from @CacheEvict
expressions as long as 'beforeInvocation' is false.

The removal of whitespace to the *.aj files made in 1762157 cause
NoSuchMethodError for code compiled against previous versions of
spring-aspects due to a bug in AspectJ (see SPR-10178 for details).
This commit reverts all the whitespace changes made in 1762157 which
resolves the NoSuchMethodErrors.

Previously aspects.gradle used the Gradle conventions for the source
and target compatibility. This means that unless the conventions were
updated the current JDK would be used for both source and target
compatibilty. Since an update to build.gradle changed to configure the
compileJava and compileTestJava tasks explicitly spring-aspects has
been compiled with JDK 7 compatibility.
This commit explicitly uses the source and target compatibility from
spring-core to ensure that aspects.gradle is kept up to date.
Issue: SPR-10161
Prior to this commit, ClassWithAsyncAnnotation#return5 forced an
unsuppressable warning in Eclipse, making it virtually impossible to
get to a zero-warnings state in the codebase.
The 'solution' here is simply to comment out the method and it's
associated test case. The 'declare warnings' functionality around
@Async is well-understood and has long been stable.
Also, the entire AnnotationAsyncExecutionAspectTests class has been
added to TestGroup#PERFORMANCE (SPR-9984), as opposed to just
asyncMethodGetsRoutedAsynchronously as it was previously, the
rationale being that all tests are actually timing dependent.

- Suppress an (intentional) AspectJ warning
- Remove unused imports
- Suppress a [hiding] warning
- Fix a generics warning related to extension of final types
Issue: SPR-9431
Prior to this commit many test utility classes and sample beans were
duplicated across projects. This was previously necessary due to the
fact that dependent test sources were not shared during a gradle
build. Since the introduction of the 'test-source-set-dependencies'
gradle plugin this is no longer the case.
This commit attempts to remove as much duplicate code as possible,
co-locating test utilities and beans in the most suitable project.
For example, test beans are now located in the 'spring-beans'
project.
Some of the duplicated code had started to drift apart when
modifications made in one project where not ported to others. All
changes have now been consolidated and when necessary existing tests
have been refactored to account for the differences.

Fix deprecation compiler warnings by refactoring code or applying
@SuppressWarnings("deprecation") annotations. JUnit tests of
internally deprecated classes are now themselves marked as
@Deprecated.
Numerous EasyMock deprecation warnings will remain until the
migration to mockito can be completed.
Fix serialization warnings by applying @SuppressWarnings("serial")
when appropriate.
In certain cases and for unknown reasons, a correctly-placed
@SuppressWarnings("serial") annotation will fix the warning at the
javac level (i.e. the Gradle command-line), but will produce an
"unnecessary @SuppressWarnings" warning within Eclipse. In these
cases, a private static final serialVersionUID field has been added
with the default value of 1L.
- Support external Javadoc links using Gradle's javadoc.options.links
- Fix all other Javadoc warnings, such as typos, references to
non-existent (or no longer existent) types and members, etc,
including changes related to the Quartz 2.0 upgrade (SPR-8275) and
adding the HTTP PATCH method (SPR-7985).
- Suppress all output for project-level `javadoc` tasks in order to
hide false-negative warnings about cross-module @see and @link
references (e.g. spring-core having a @see reference to spring-web).
Use the `--info` (-i) flag to gradle at any time to see project-level
javadoc warnings without running the entire `api` task. e.g.
`gradle :spring-core:javadoc -i`
- Favor root project level `api` task for detection of legitimate
Javadoc warnings. There are now zero Javadoc warnings across the
entirety of spring-framework. Goal: keep it that way.
- Remove all @link and @see references to types and members that exist
only in Servlet <= 2.5 and Hibernate <= 4.0, favoring 3.0+ and 4.0+
respectively. This is necessary because only one version of each of
these dependencies can be present on the global `api` javadoc task's
classpath. To that end, the `api` task classpath has now been
customized to ensure that the Servlet 3 API and Hibernate Core 4 jars
have precedence.
- SPR-8896 replaced our dependency on aspectjrt with a dependency on
aspectjweaver, which is fine from a POM point of view, but causes
a spurious warning to be emitted from the ant iajc task that it
"cannot find aspectjrt on the classpath" - even though aspectjweaver
is perfectly sufficient. In the name of keeping the console quiet, a
new `rt` configuration has been added, and aspectjrt added as a
dependency to it. In turn, configurations.rt.asPath is appended to
the iajc classpath during both compileJava and compileTestJava for
spring-aspects.

Replace existing 'optional' and 'provided' Spring specific build
extensions with a new Gradle propdeps-plugin. Optional and Provided
dependencies are now defined use dependency configurations.
The new plugin does not currently support the notion of optional
runtime dependencies. All optional dependencies are implicitly
part of the 'compile' scope. This is an intentional design decision
that aims to keep both the plugin and the build simple. Since optional
dependencies are non-transitive this restriction should not cause
any real problems for existing users. The only existing dependency
affected is 'commons-io' in the 'spring-beans' project, however, this
was an optional compile scope dependency in the previous Spring 3.1
release.
Both provided and optional dependencies are no longer exported from
generated eclipse .classpath files. This fixes several tests that
would previously fail when running within eclipse. The servlet-api
specific elements of ide.gradle are also no longer required.
Issue: SPR-9656, SPR-10070
Commit 5327a7a37d moved
@EnableSpringConfigured from beans.factory.aspectj =>
context.annotation within the spring-aspects module. This resolved a
package cycle but had the side-effect of causing a "split package" [1]
problem between spring-context and spring-aspects in OSGi-based
classloader environments because the context.annotation package now
exists in both modules.
The simplest and best solution from an OSGi perspective is to relocate
@EnableSpringConfigured and its supporting SpringConfiguredConfiguration
class into a new package. This commit moves both these types into
context.annotation.aspectj, following convention with other such
"aspectj"-qualified packages in the spring-aspects module.
As with the previous move, it is presumed this change will be low-impact
as the "spring-configured" approach to domain object injection is a
niche feature to begin with, and @EnableSpringConfigured has existed in
its current location only since 3.1.2 and this change is being made in
time for 3.1.3.

- Explicitly specify compile-time dependencies on other spring-*
modules, primarily for accuracy in pom generation and ensuring
minimal dependencies for users of spring-aspects.
- Remove use of p: namespace from annotation-cache-aspectj.xml to
avoid parser-related test failures under Eclipse (likely due to
classpath differences between Gradle and Eclipse).
@EnableSpringConfigured and its @Import'ed
SpringConfiguredConfiguration @Configuration class inadvertently
established a package cycle between beans.factory.aspectj and
context.annotation due to SpringConfiguredConfiguration's
dependency on annotations such as @Configuration, @Bean and @Role.
This commit fixes this architecture bug by moving
@EnableSpringConfigured and SpringConfiguredConfiguration from the
beans.factory.aspectj package to the context.annotation package where
they belong.
This change is assumed to be very low impact as @EnableSpringConfigured
was introduced in 3.1.0 and relocation is happening as quickly as
possible in 3.1.2. @EnableSpringConfigured is assumed to be infrequently
used at this point, and for those that are the migration path
is straightforward. When upgrading from Spring 3.1.0 or 3.1.1, update
import statements in any affected @Configuration classes to reflect the
new packaging.
Issue: SPR-9441
Prior to this change, Spring's @Async annotation support was tied to a
single AsyncTaskExecutor bean, meaning that all methods marked with
@Async were forced to use the same executor. This is an undesirable
limitation, given that certain methods may have different priorities,
etc. This leads to the need to (optionally) qualify which executor
should handle each method.
This is similar to the way that Spring's @Transactional annotation was
originally tied to a single PlatformTransactionManager, but in Spring
3.0 was enhanced to allow for a qualifier via the #value attribute, e.g.
@Transactional("ptm1")
public void m() { ... }
where "ptm1" is either the name of a PlatformTransactionManager bean or
a qualifier value associated with a PlatformTransactionManager bean,
e.g. via the <qualifier> element in XML or the @Qualifier annotation.
This commit introduces the same approach to @Async and its relationship
to underlying executor beans. As always, the following syntax remains
supported
@Async
public void m() { ... }
indicating that calls to #m will be delegated to the "default" executor,
i.e. the executor provided to
<task:annotation-driven executor="..."/>
or the executor specified when authoring a @Configuration class that
implements AsyncConfigurer and its #getAsyncExecutor method.
However, it now also possible to qualify which executor should be used
on a method-by-method basis, e.g.
@Async("e1")
public void m() { ... }
indicating that calls to #m will be delegated to the executor bean
named or otherwise qualified as "e1". Unlike the default executor
which is specified up front at configuration time as described above,
the "e1" executor bean is looked up within the container on the first
execution of #m and then cached in association with that method for the
lifetime of the container.
Class-level use of Async#value behaves as expected, indicating that all
methods within the annotated class should be executed with the named
executor. In the case of both method- and class-level annotations, any
method-level #value overrides any class level #value.
This commit introduces the following major changes:
- Add @Async#value attribute for executor qualification
- Introduce AsyncExecutionAspectSupport as a common base class for
both MethodInterceptor- and AspectJ-based async aspects. This base
class provides common structure for specifying the default executor
(#setExecutor) as well as logic for determining (and caching) which
executor should execute a given method (#determineAsyncExecutor) and
an abstract method to allow subclasses to provide specific strategies
for executor qualification (#getExecutorQualifier).
- Introduce AnnotationAsyncExecutionInterceptor as a specialization of
the existing AsyncExecutionInterceptor to allow for introspection of
the @Async annotation and its #value attribute for a given method.
Note that this new subclass was necessary for packaging reasons -
the original AsyncExecutionInterceptor lives in
org.springframework.aop and therefore does not have visibility to
the @Async annotation in org.springframework.scheduling.annotation.
This new subclass replaces usage of AsyncExecutionInterceptor
throughout the framework, though the latter remains usable and
undeprecated for compatibility with any existing third-party
extensions.
- Add documentation to spring-task-3.2.xsd and reference manual
explaining @Async executor qualification
- Add tests covering all new functionality
Note that the public API of all affected components remains backward-
compatible.
Issue: SPR-6847
In anticipation of substantive changes required to implement @Async
executor qualification, the following updates have been made to the
components and infrastructure supporting @Async functionality:
- Fix trailing whitespace and indentation errors
- Fix generics warnings
- Add Javadoc where missing, update to use {@code} tags, etc.
- Avoid NPE in AopUtils#canApply
- Organize imports to follow conventions
- Remove System.out.println statements from tests
- Correct various punctuation and grammar problems
Before this change there were numerous javadoc warnings being reported
while building Spring framework API.
This commit resolves most of the javadoc warnings, reducing the total
number from 265 to 103.
Issue: SPR-9113
- Fix compileTestJava issue in which test classes were not being
compiled or run
- Use built-in eclipse.project DSL instead of withXml closure
to add AspectJ nature and builder
- Rename {aspectJ=>aspects}.gradle and format source
This renaming more intuitively expresses the relationship between
subprojects and the JAR artifacts they produce.
Tracking history across these renames is possible, but it requires
use of the --follow flag to `git log`, for example
$ git log spring-aop/src/main/java/org/springframework/aop/Advisor.java
will show history up until the renaming event, where
$ git log --follow spring-aop/src/main/java/org/springframework/aop/Advisor.java
will show history for all changes to the file, before and after the
renaming.
