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
*/
@Service
public 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);
}
}
