Class SimpleTaskScheduler

java.lang.Object
  org.springframework.integration.scheduling.SimpleTaskScheduler

All Implemented Interfaces:

java.util.EventListener, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.DisposableBean, org.springframework.context.ApplicationListener, org.springframework.context.Lifecycle, TaskScheduler

public class SimpleTaskScheduler
extends java.lang.Object
implements TaskScheduler, org.springframework.beans.factory.BeanFactoryAware, org.springframework.context.ApplicationListener, org.springframework.beans.factory.DisposableBean

An implementation of TaskScheduler that delegates to any instance of TaskExecutor.

This class implements ApplicationListener and provides an autoStartup property. If true, the scheduler will start automatically upon receiving the ContextRefreshedEvent. Otherwise, it will require an explicit invocation of its start() method. The default value is true. To require explicit startup, provide a value of false to the setAutoStartup(boolean) method.
