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
