spring schedule 注解方式实现任务调试

1、在sprng配置xml文件引入命名空间

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

在xsi:schemaLocation加入
http://www.springframework.org/schema/task  
http://www.springframework.org/schema/task/spring-task-3.0.xsd

局部配置如下

<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:tx="http://www.springframework.org/schema/tx" xmlns:jdbc="http://www.springframework.org/schema/jdbc"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:task="http://www.springframework.org/schema/task"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd
http://www.springframework.org/schema/task
http://www.springframework.org/schema/task/spring-task-3.0.xsd">


2、Spring相关配置如下:

 <!-- 配置注解扫描 -->  
<context:annotation-config />

<!-- 自动扫描的包名 -->
<context:component-scan base-package="cn.com.abel.test.schedule" />

<!-- spring定时器注解开关-->
<task:annotation-driven/>

3、java类实现

package cn.com.abel.test.schedule;

import java.util.Date;

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

@Component
public class TestTaskSchedule {
/** 
  * cron表达式:* * * * * *(共6位,使用空格隔开,具体如下) 
  * cron表达式:*(秒0-59) *(分钟0-59) *(小时0-23) *(日期1-31) *(月份1-12或是JAN-DEC) *(星期1-7或是SUN-SAT) 
  */
@Scheduled(cron="0/5 * * * * ? ") //每5秒执行一次
public void myTest(){
System.out.println("进入测试"+new Date());
}
}
