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:
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:
context-trigger.xml内容如下:

2、 开发定时器类,实例代码如下:
1
public
class
TriggerUtil
{
2
3 private TriggerUtil(){
4
5 }
6
7 public void expDataBase(){
8 System.out.println("trigger actived..");
9 }
10
11}
3、
配置定时任务2
3 private TriggerUtil(){
4
5 }
6
7 public void expDataBase(){
8 System.out.println("trigger actived..");
9 }
10
11}
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:
1
<?
xml version="1.0" encoding="UTF-8"
?>
