基于spring+quartz开发定时器

1、 准备Jar包
在Spring所有包齐全的前提下还要导入一个定时器工具包：quartz-1.6.2.jar < http://www.opensymphony.com/quartz/download.action>
2、 开发定时器类，实例代码如下：

public class TriggerUtil

{
2

private TriggerUtil()

{
4

}
6

public void expDataBase()

{
8

System.out.println("trigger actived

..");
9

}
10

}

3、 配置定时任务
为了清晰代码结构，单独建立一个配置定时任务的配置文件context-trigger.xml，并在applicationContext.xml进行import：

< import resource ="context-trigger.xml" />

context-trigger.xml内容如下：

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

< beans
