1、Quartz
Quartz是Job Scheduling(任务调度)领域的开源项目，可单独使用，也可和JavaSE,EE进行组合，是一个任务调度管理系统，可在特定的时间内执行特定的任务,如想在Java中使用Quartz,则只需将Quartz的jar包导入到项目中即可。
完全由Java开发，可以用来执行定时任务
2、修改beans.xml
<import resource="spring-quartz.xml"/>
3、spring-quartz.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
