cn.taketoday.scheduling.annotation.AsyncAnnotationAdvisor

所有已实现的接口:

Advisor, PointcutAdvisor, Aware, BeanFactoryAware, cn.taketoday.core.Ordered, Serializable

public class AsyncAnnotationAdvisor
extends AbstractPointcutAdvisor
implements 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 jakarta.ejb.Asynchronous annotation as well, treating it exactly like own Async. Furthermore, a custom async annotation type may get specified through the "asyncAnnotationType" property.

从以下版本开始:

4.0

AsyncAnnotationAdvisor

public AsyncAnnotationAdvisor()

Create a new AsyncAnnotationAdvisor for bean-style configuration.

AsyncAnnotationAdvisor

public AsyncAnnotationAdvisor(@Nullable
 Executor executor,
 @Nullable
 AsyncUncaughtExceptionHandler exceptionHandler)

Create a new AsyncAnnotationAdvisor for the given task executor.

参数:

executor - the task executor to use for asynchronous methods (can be null to trigger default executor resolution)

exceptionHandler - the AsyncUncaughtExceptionHandler to use to handle unexpected exception thrown by asynchronous method executions

• AsyncExecutionInterceptor.getDefaultExecutor(BeanFactory)

AsyncAnnotationAdvisor

public AsyncAnnotationAdvisor(@Nullable
 Supplier<Executor> executor,
 @Nullable
 Supplier<AsyncUncaughtExceptionHandler> exceptionHandler)

Create a new AsyncAnnotationAdvisor for the given task executor.

参数:

executor - the task executor to use for asynchronous methods (can be null to trigger default executor resolution)

exceptionHandler - the AsyncUncaughtExceptionHandler to use to handle unexpected exception thrown by asynchronous method executions

另请参阅:

• AsyncExecutionInterceptor.getDefaultExecutor(BeanFactory)

方法详细资料

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 jakarta.ejb.Asynchronous annotation (if present).

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

参数:

asyncAnnotationType - the desired annotation type

setBeanFactory

public void setBeanFactory(BeanFactory beanFactory)

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

指定者:

setBeanFactory 在接口中 BeanFactoryAware

getAdvice

public Advice getAdvice()

指定者:

getAdvice 在接口中 Advisor

getPointcut

public Pointcut getPointcut()

指定者:

getPointcut 在接口中 PointcutAdvisor

buildAdvice

protected Advice buildAdvice(@Nullable
 Supplier<Executor> executor,
 @Nullable
 Supplier<AsyncUncaughtExceptionHandler> exceptionHandler)

buildPointcut

protected Pointcut buildPointcut(Set<Class<? extends Annotation>> asyncAnnotationTypes)

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

参数:

asyncAnnotationTypes - the async annotation types to introspect

返回:

the applicable Pointcut object, or null if none
