java.lang.Object

org.springframework.aop.support.AbstractPointcutAdvisor

org.springframework.scheduling.annotation.AsyncAnnotationAdvisor

All Implemented Interfaces:

Serializable, org.springframework.aop.Advisor, org.springframework.aop.PointcutAdvisor, org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanFactoryAware, org.springframework.core.Ordered

public class AsyncAnnotationAdvisor
extends org.springframework.aop.support.AbstractPointcutAdvisor
implements org.springframework.beans.factory.BeanFactoryAware

Advisor that activates asynchronous method execution through the Async annotation. This annotation can be used at the method and type level in implementation classes as well as in service interfaces.

This advisor detects the EJB 3.1 javax.ejb.Asynchronous annotation as well, treating it exactly like Spring's own Async. Furthermore, a custom async annotation type may get specified through the "asyncAnnotationType" property.

Since:

3.0

Constructor Detail

AsyncAnnotationAdvisor

public AsyncAnnotationAdvisor()

Create a new AsyncAnnotationAdvisor for bean-style configuration.

AsyncAnnotationAdvisor

public AsyncAnnotationAdvisor(Executor executor)

Create a new AsyncAnnotationAdvisor for the given task executor.

Parameters:

executor - the task executor to use for asynchronous methods

Method Detail

setBeanFactory

public void setBeanFactory(org.springframework.beans.factory.BeanFactory beanFactory)
                    throws org.springframework.beans.BeansException

Set the BeanFactory to be used when looking up executors by qualifier.

Specified by:

setBeanFactory in interface org.springframework.beans.factory.BeanFactoryAware

Throws:

org.springframework.beans.BeansException

delegateBeanFactory

public void delegateBeanFactory(org.springframework.beans.factory.BeanFactory beanFactory)

setTaskExecutor

public void setTaskExecutor(Executor executor)

Specify the task executor to use for asynchronous methods.

setAsyncAnnotationType

public void setAsyncAnnotationType(Class<? extends Annotation> asyncAnnotationType)

Set the 'async' annotation type.

The default async annotation type is the Async annotation, as well as the EJB 3.1 javax.ejb.Asynchronous annotation (if present).

This setter property exists so that developers can provide their own (non-Spring-specific) annotation type to indicate that a method is to be executed asynchronously.

Parameters:

asyncAnnotationType - the desired annotation type

getAdvice

public Advice getAdvice()

Specified by:

getAdvice in interface org.springframework.aop.Advisor

getPointcut

public org.springframework.aop.Pointcut getPointcut()

Specified by:

getPointcut in interface org.springframework.aop.PointcutAdvisor

buildAdvice

protected Advice buildAdvice(Executor executor)

buildPointcut

protected org.springframework.aop.Pointcut buildPointcut(Set<Class<? extends Annotation>> asyncAnnotationTypes)

Calculate a pointcut for the given async annotation types, if any.

Parameters:

asyncAnnotationTypes - the async annotation types to introspect

Returns:

the applicable Pointcut object, or null if none
