类:

package com.task;

import java.util.Date;

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

@Component("taskJob")
public class TaskJob {

int i=0;

@Scheduled(cron = "0/5 * * * * ?")
public void job1() {
System.out.println((i++)+" taskJob:::"+new Date());
}
}

spring配置文件中添加:

beans里:
xmlns:task="http://www.springframework.org/schema/task"
xsi:schemaLocation添加:
http://www.springframework.org/schema/task
http://www.springframework.org/schema/task/spring-task-3.1.xsd

<context:component-scan base-package="com.bbs.task" />
<task:annotation-driven />

tomcat启动后控制台会输出:

0 taskJob:::Wed Oct 12 09:24:55 CST 2016
1 taskJob:::Wed Oct 12 09:25:00 CST 2016
2 taskJob:::Wed Oct 12 09:25:05 CST 2016
3 taskJob:::Wed Oct 12 09:25:10 CST 2016
