spring+task配置

1.spring+task文件配置

<?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:task="http://www.springframework.org/schema/task"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-4.2.xsd
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd">


    <task:annotation-driven/>
    <context:component-scan base-package="com.task"/>
</beans>

2.业务类

package com.task;

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

@Component
public class TestScheduled {

     @Scheduled(cron="0/5 * *  * * ? ")   //每5秒执行一次  
    public void test(){
        for(long i=0;i<1000000000000000000l;i++){
            System.out.print((char)i);
            if(i%15==0){
                System.out.println();
            }
        }
    }
}

启动程序就开始跑了
