Imports
java.lang.reflect.Method, java.util.concurrent.Executor, org.springframework.aop.interceptor.AsyncExecutionInterceptor, .AsyncUncaughtExceptionHandler, org.springframework.core.annotation.AnnotatedElementUtils, org.springframework.lang.Nullable
Specialization of AsyncExecutionInterceptor that delegates method execution to an Executor based on the Async annotation.

Specifically designed to support use of the Async#value() executor qualifier mechanism.

Supports detecting qualifier metadata via @Async at the method or declaring class level. See getExecutorQualifier(Method) for details.

Constructor Summary

AccessConstructor and Description
public
AnnotationAsyncExecutionInterceptor(Executor
the executor to be used by default if no more specific executor has been qualified at the method level using Async#value(); a local executor for this interceptor will be built otherwise
defaultExecutor)

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

public
AnnotationAsyncExecutionInterceptor(Executor
the executor to be used by default if no more specific executor has been qualified at the method level using Async#value(); a local executor for this interceptor will be built otherwise
defaultExecutor, AsyncUncaughtExceptionHandler
the AsyncUncaughtExceptionHandler to use to handle exceptions thrown by asynchronous method executions with void return type
exceptionHandler)

Create a new AnnotationAsyncExecutionInterceptor with the given executor.

Method Summary

Modifier and TypeMethod and Description
protected String

Returns:

the qualifier if specified, otherwise an empty string indicating that the default executor should be used
getExecutorQualifier(Method
the method to inspect for executor qualifier metadata
method)

Overrides org.springframework.aop.interceptor.AsyncExecutionInterceptor.getExecutorQualifier.

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.

Constructor Detail

AnnotationAsyncExecutionInterceptorback to summary
public AnnotationAsyncExecutionInterceptor(Executor defaultExecutor)

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

Parameters
defaultExecutor:Executor

the executor to be used by default if no more specific executor has been qualified at the method level using Async#value(); a local executor for this interceptor will be built otherwise

AnnotationAsyncExecutionInterceptorback to summary
public AnnotationAsyncExecutionInterceptor(Executor defaultExecutor, AsyncUncaughtExceptionHandler exceptionHandler)

Create a new AnnotationAsyncExecutionInterceptor with the given executor.

Parameters
defaultExecutor:Executor

the executor to be used by default if no more specific executor has been qualified at the method level using Async#value(); a local executor for this interceptor will be built otherwise

exceptionHandler:AsyncUncaughtExceptionHandler

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

Method Detail

getExecutorQualifierback to summary
protected String getExecutorQualifier(Method method)

Overrides org.springframework.aop.interceptor.AsyncExecutionInterceptor.getExecutorQualifier.

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).

Parameters
method:Method

the method to inspect for executor qualifier metadata

Returns:String

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