Class ScheduledAnnotationBeanPostProcessor

java.lang.Object

org.springframework.scheduling.annotation.ScheduledAnnotationBeanPostProcessor

All Implemented Interfaces:

org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.config.BeanPostProcessor, org.springframework.beans.factory.DisposableBean, org.springframework.beans.factory.SmartInitializingSingleton, EmbeddedValueResolverAware, org.springframework.core.Ordered

public class ScheduledAnnotationBeanPostProcessor
extends java.lang.Object
implements org.springframework.beans.factory.config.BeanPostProcessor, org.springframework.core.Ordered, EmbeddedValueResolverAware, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.SmartInitializingSingleton, 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

void	setScheduler(java.lang.Object scheduler) Set the TaskScheduler that will invoke the scheduled methods, or a ScheduledExecutorService to be wrapped as a TaskScheduler.
