定义一个定时操作

package com.jCuckoo.demo;import java.text.SimpleDateFormat;import java.util.Date;import org.springframework.scheduling.annotation.Scheduled;public class Singer {//@Scheduled(fixedDelay=1000)  //第一种方式//fixedDelay延时多少毫秒，多少毫秒执行一次@Scheduled(cron="0 * * * * *")     //第二种方式/*1 Seconds (0-59)2 Minutes (0-59)3 Hours (0-23)4 Day of month (1-31)5 Month (1-12 or JAN-DEC)6 Day of week (1-7 or SUN-SAT)7 Year (1970-2099)取值：可以是单个值，如6；也可以是个范围，如9-12；也可以是个列表，如9,11,13也可以是任意取值，使用**///0 * * * * * 代表每分钟执行一次/* 2011-09-07 09:23:002011-09-07 09:24:002011-09-07 09:25:002011-09-07 09:26:00 */public void singing(){Date date=new Date();SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");System.out.println(sdf.format(date));}}

spring配置文件如下：

<?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:aop="http://www.springframework.org/schema/aop"xmlns:tx="http://www.springframework.org/schema/tx" xmlns:task="http://www.springframework.org/schema/task"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx-3.0.xsdhttp://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop-3.0.xsdhttp://www.springframework.org/schema/taskhttp://www.springframework.org/schema/task/spring-task-3.0.xsd"><bean id="singer" class="com.jCuckoo.demo.Singer"/><task:annotation-driven /></beans>

测试类

package com.jCuckoo.demo;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class MainTest {public static void main(String[] args) {ApplicationContext context=new ClassPathXmlApplicationContext("applicationContext.xml");Singer singer=(Singer) context.getBean("singer");}}

结果：

2011-09-07 09:23:00
2011-09-07 09:24:00
2011-09-07 09:25:00
2011-09-07 09:26:00
