Java定时任务注解方式实现

Spring 注解的定时任务，有如下两种方式：

第一种：

<?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:p="http://www.springframework.org/schema/p"

?xmlns:jee="http://www.springframework.org/schema/jee"? 

?xmlns:tx="http://www.springframework.org/schema/tx"? 

?xmlns:context="http://www.springframework.org/schema/context"? 

?xmlns:aop="http://www.springframework.org/schema/aop"? 

?xmlns:task="http://www.springframework.org/schema/task"

?xsi:schemaLocation="
? http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd

?">
<!-- 第一种方式-->
	 <task:scheduled-tasks>
	 	<!-- 说明：ref参数指定的即任务类，method指定的即需要运行的方法 -->
	 	<task:scheduled ref="jobService" method="job1" cron="0/4 * * * * ?" />
	 </task:scheduled-tasks>
	 
	 <!-- Spring 扫描注解,自动将用注解标注的类，就行实例化 -->
	 
	 <context:component-scan base-package="com.TimerWay.quartz3 " />
</beans>

?

package com.TimerWay.quartz3;

import org.springframework.stereotype.Service; 

@Service  
public class JobService {  
      
    public void job1() {  
        System.out.println("任务进行中。。。");  
    }  
}  ?

第二种：

<?xml version="1.0" encoding="UTF-8"?>

<!-- spring扫描注解的配置 -->  
     <context:component-scan base-package="com.TimerWay.quartz3" />  
     
     <!-- 配置 @Scheduled注解 -->
     <task:annotation-driven />
</beans>

?

package com.TimerWay.quartz3;

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

@Service("jobServiceTwo")
public class JobServiceTwo {
	@Scheduled(cron = "0/5 * * * * ?")  
    public void job1() {  
        System.out.println("任务进行中2。。。");
    }  
}
