public class AsyncAnnotationBeanPostProcessor extends AbstractBeanFactoryAwareAdvisingPostProcessor
Bean post-processor that automatically applies asynchronous invocation behavior to any bean that carries the Async annotation at class or method-level by adding a corresponding AsyncAnnotationAdvisor to the exposed proxy (either an existing AOP proxy or a newly generated proxy that implements all of the target's interfaces).

The TaskExecutor responsible for the asynchronous execution may be provided as well as the annotation type that indicates a method should be invoked asynchronously. If no annotation type is specified, this post- processor will detect both @Async annotation as well as the EJB 3.1 jakarta.ejb.Asynchronous annotation.

For methods having a void return type, any exception thrown during the asynchronous method invocation cannot be accessed by the caller. An AsyncUncaughtExceptionHandler can be specified to handle these cases.

Note: The underlying async advisor applies before existing advisors by default, in order to switch to async execution as early as possible in the invocation chain.

    • configure

      public void configure(@Nullable Supplier<Executor> executor, @Nullable Supplier<AsyncUncaughtExceptionHandler> exceptionHandler)
      Configure this post-processor with the given executor and exception handler suppliers, applying the corresponding default if a supplier is not resolvable.

    • setExecutor

      public void setExecutor(Executor executor)
      Set the Executor to use when invoking methods asynchronously.

      If not specified, default executor resolution will apply: searching for a unique TaskExecutor bean in the context, or for an Executor bean named "taskExecutor" otherwise. If neither of the two is resolvable, a local default executor will be created within the interceptor.

    • setExceptionHandler

      public void setExceptionHandler(AsyncUncaughtExceptionHandler exceptionHandler)
      Set the AsyncUncaughtExceptionHandler to use to handle uncaught exceptions thrown by asynchronous method executions.

    • setAsyncAnnotationType

      public void setAsyncAnnotationType(Class<? extends Annotation> asyncAnnotationType)
      Set the 'async' annotation type to be detected at either class or method level. By default, both the Async annotation and the EJB 3.1 jakarta.ejb.Asynchronous annotation will be detected.

      This setter property exists so that developers can provide their own (non-specific) annotation type to indicate that a method (or all methods of a given class) should be invoked asynchronously.

      参数:
      asyncAnnotationType - the desired annotation type
