Class ScheduledAnnotationBeanPostProcessor

java.lang.Object

org.springframework.scheduling.annotation.ScheduledAnnotationBeanPostProcessor

All Implemented Interfaces:

java.util.EventListener, org.springframework.beans.factory.Aware, org.springframework.beans.factory.config.BeanPostProcessor, org.springframework.beans.factory.DisposableBean, ApplicationContextAware, ApplicationListener<ContextRefreshedEvent>, EmbeddedValueResolverAware, org.springframework.core.Ordered

public class ScheduledAnnotationBeanPostProcessor
extends java.lang.Object
implements org.springframework.beans.factory.config.BeanPostProcessor, org.springframework.core.Ordered, EmbeddedValueResolverAware, ApplicationContextAware, ApplicationListener<ContextRefreshedEvent>, org.springframework.beans.factory.DisposableBean

Bean post-processor that registers methods annotated with @Scheduled to be invoked by a TaskScheduler according to the "fixedRate", "fixedDelay", or "cron" expression provided via the annotation.

This post-processor is automatically registered by Spring's <task:annotation-driven> XML element, and also by the @EnableScheduling annotation.

Auto-detects any SchedulingConfigurer instances in the container, allowing for customization of the scheduler to be used or for fine-grained control over task registration (e.g. registration of Trigger tasks. See the @EnableScheduling javadocs for complete usage details.

Since:

3.0

Method Detail

getOrder

public int getOrder()

Specified by:

getOrder in interface org.springframework.core.Ordered

setScheduler

public void setScheduler(java.lang.Object scheduler)

Set the TaskScheduler that will invoke the scheduled methods, or a ScheduledExecutorService to be wrapped as a TaskScheduler.

setEmbeddedValueResolver

public void setEmbeddedValueResolver(org.springframework.util.StringValueResolver resolver)

Description copied from interface: EmbeddedValueResolverAware

Set the StringValueResolver to use for resolving embedded definition values.

Specified by:

setEmbeddedValueResolver in interface EmbeddedValueResolverAware

setApplicationContext

public void setApplicationContext(ApplicationContext applicationContext)

Description copied from interface: ApplicationContextAware

Set the ApplicationContext that this object runs in. Normally this call will be used to initialize the object.

Invoked after population of normal bean properties but before an init callback such as InitializingBean.afterPropertiesSet() or a custom init-method. Invoked after ResourceLoaderAware.setResourceLoader(org.springframework.core.io.ResourceLoader), ApplicationEventPublisherAware.setApplicationEventPublisher(org.springframework.context.ApplicationEventPublisher) and MessageSourceAware, if applicable.

Specified by:

setApplicationContext in interface ApplicationContextAware

Parameters:

applicationContext - the ApplicationContext object to be used by this object

BeanInitializationException

onApplicationEvent

public void onApplicationEvent(ContextRefreshedEvent event)

Description copied from interface: ApplicationListener

Handle an application event.

Specified by:

onApplicationEvent in interface ApplicationListener<ContextRefreshedEvent>

Parameters:

event - the event to respond to

postProcessBeforeInitialization

                                                        java.lang.String beanName)

Specified by:

postProcessBeforeInitialization in interface org.springframework.beans.factory.config.BeanPostProcessor

postProcessAfterInitialization

public java.lang.Object postProcessAfterInitialization(java.lang.Object bean,
                                                       java.lang.String beanName)

Specified by:

postProcessAfterInitialization in interface org.springframework.beans.factory.config.BeanPostProcessor

processScheduled

protected void processScheduled(Scheduled scheduled,
                                java.lang.reflect.Method method,
                                java.lang.Object bean)
