Spring 定时任务介绍

从spring 3.1开始，计划任务在Spring中的实现变得异常的简单，首先通过类注解@EnableScheduing 来开启对计划任务的支持！然后在要执行的计划任务上面添加@Scheduled，声明这是一个计划任务！

计划执行类

ScheduledTaskService.java

package com.stormma.service;import org.springframework.scheduling.annotation.Scheduled;import org.springframework.stereotype.Service;import java.text.SimpleDateFormat;import java.util.Date;/** * <p>Created by StormMa on 2017/1/28.</p> * * @author StormMa */@Servicepublic class ScheduledTaskService {    private static final SimpleDateFormat dateFormat = new            SimpleDateFormat("HH:mm:ss");    @Scheduled(fixedRate = 5000)    public void reportCurrentTime() {        System.out.println("每隔五秒钟执行一次： " + dateFormat.format(new Date()));    }    @Scheduled(cron = "0 28 11 ? * *")    public void fixTimeExecution() {        System.out.println("在指定时间 " + dateFormat.format(new Date()) + "执行");    }}

配置类

MyConfig.java

package com.stormma.config;import org.springframework.context.annotation.ComponentScan;import org.springframework.context.annotation.Configuration;import org.springframework.scheduling.annotation.EnableScheduling;/** * <p>Created by StormMa on 2017/1/28.</p> * * @author StormMa */@Configuration@EnableScheduling@ComponentScan("com.stormma")public class MyConfig {}

运行类

Client.java

package com.stormma.client;import com.stormma.config.MyConfig;import org.springframework.context.annotation.AnnotationConfigApplicationContext;/** * <P>Created by StormMa on 2017/1/28.</P> * * @author StormMa */public class Client {    public static void main(String [] args) {        AnnotationConfigApplicationContext context = new                AnnotationConfigApplicationContext(MyConfig.class);    }}
