Chris Beams	ed0576c181	Support executor qualification with @Async#value 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.

Chris Beams	3fb11870d9	Polish async method execution infrastructure 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	13 years ago
Stevo Slavic	effb762558	Fix javadoc warnings 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	13 years ago
Chris Beams	5ea51f42fb	Fix and refactor spring-aspects build - 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	13 years ago

Chris Beams	02a4473c62	Rename modules {org.springframework.=>spring-} 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.
