Spring 任务调度

这里采用Spring 3.2.4.RELEASE版本进行测试

1. 首先定义一个启动类：

package com.jacksoft.ispring.test.one;

import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

/**
 *  启动
 * @Project iSpring
 *
 * @Filename Main.java
 *
 * @author Jack.Zhou
 *
 * @Date 2013-11-1
 *
 */
@Configuration
@ComponentScan("com.jacksoft.ispring.test.one")
public class Main {
	
	public static void main(String[] args) {
		ApplicationContext context = new AnnotationConfigApplicationContext(Main.class);
	}
}

    这个类在启动的时候会扫描com.jacksoft.ispring.test.one目录下面的注解类，而我们的任务类也在这个包下面

 

package com.jacksoft.ispring.test.one;

import java.text.SimpleDateFormat;
import java.util.Date;

import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

/**
 *   http://spring.io/guides/gs/scheduling-tasks/
 *   Spring schedule task
 *   
 *   需要添加@Component注解，让spring能进行扫描
 *   
 * @Project iSpring
 *
 * @Filename ScheduleTasks.java
 *
 * @author Jack.Zhou
 *
 * @Date 2013-11-1
 *
 */
@EnableScheduling
@Component
public class ScheduleTasks {

	private static final SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");
	
	@Scheduled(cron="*/10 * * * * *")
	public void reportTimes(){
		System.out.println("The time now is:" + dateFormat.format(new Date()));
	}
	
}

 

  通过注解来设置该类为任务类，然后通过直接main刚发，即可以完成任务定时执行

 

 这也是参考spring官网上的例子来的，可以参考：
