备注：这个是基于搭建好spring的环境下的
注解方式：
1.定时任务类
package com.test;
import java.util.Date;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
@Component("mytask")
public class MyTask {
int i =0;
@Scheduled(cron = "0 0/1 * * * ?")//！！！！！表示每分钟执行一次！！！！！cron是表示触发的时间表达式
public void doTask(){
System.out.println("结果是："+(i++)+":"+new Date());
}
}2.配置文件：schedule.xml；备注：名称随便起。还有，需要在总的配置文件映入改文件

<!-- 扫描定时任务类所在的包 -->
<context:component-scan base-package="com.test" /> </beans>
XML方式：
1.定时任务类：相比注解方式，方法上面没有注解，通过XML方式注入
@Component("mytask")
public class MyTask {
int i =0;
public void doTask(){
System.out.println("结果是："+(i++)+":"+new Date());
}
}2.配置文件：schedule.x
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"

xmlns:aop="http://www.springframework.org/schema/aop"> <!-- <context:annotation-config /> -->
<!-- 扫描定时任务类所在的包 -->
<task:scheduled-tasks>
<task:scheduled ref="cancelSysSeatByTask" method="doTask" cron="0 0/1 * * * ?"/>
</task:scheduled-tasks> </beans>
3.部署到tomcat并且启动，看看后台是否输出以下信息：
结果是：0:Mon Mar 30 16:23:00 CST 2015
结果是：1:Mon Mar 30 16:24:00 CST 2015
结果是：2:Mon Mar 30 16:25:00 CST 2015
