public class AnnotationAsyncExecutionInterceptor
extends org.springframework.aop.interceptor.AsyncExecutionInterceptor

Specialization of AsyncExecutionInterceptor that delegates method execution to an Executor based on the Async annotation. Specifically designed to support use of Async.value() executor qualification mechanism introduced in Spring 3.1.2. Supports detecting qualifier metadata via @Async at the method or declaring class level. See getExecutorQualifier(Method) for details.

从以下版本开始:

3.1.2

AnnotationAsyncExecutionInterceptor

public AnnotationAsyncExecutionInterceptor(@Nullable
                                           Executor defaultExecutor)

Create a new AnnotationAsyncExecutionInterceptor with the given executor and a simple AsyncUncaughtExceptionHandler.

参数:

defaultExecutor - the executor to be used by default if no more specific executor has been qualified at the method level using Async.value(); as of 4.2.6, a local executor for this interceptor will be built otherwise

AnnotationAsyncExecutionInterceptor

public AnnotationAsyncExecutionInterceptor(@Nullable
                                           Executor defaultExecutor,
                                           org.springframework.aop.interceptor.AsyncUncaughtExceptionHandler exceptionHandler)

Create a new AnnotationAsyncExecutionInterceptor with the given executor.

参数:

defaultExecutor - the executor to be used by default if no more specific executor has been qualified at the method level using Async.value(); as of 4.2.6, a local executor for this interceptor will be built otherwise

exceptionHandler - the AsyncUncaughtExceptionHandler to use to handle exceptions thrown by asynchronous method executions with void return type

方法详细资料

getExecutorQualifier

@Nullable
protected String getExecutorQualifier(Method method)

Return the qualifier or bean name of the executor to be used when executing the given method, specified via Async.value() at the method or declaring class level. If @Async is specified at both the method and class level, the method's #value takes precedence (even if empty string, indicating that the default executor should be used preferentially).

覆盖:

getExecutorQualifier 在类中 org.springframework.aop.interceptor.AsyncExecutionInterceptor

参数:

method - the method to inspect for executor qualifier metadata

返回:

the qualifier if specified, otherwise empty string indicating that the default executor should be used
