基于spring+quartz开发定时器

一、 准备Jar包
在Spring全部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>
二、 开发定时器类，实例代码以下：

public class TriggerUtil

{
2

private TriggerUtil()

{
4

}
6

public void expDataBase()

{
8

System.out.println("trigger actived

..");
9

}
10

}

三、 配置定时任务
为了清晰代码结构，单独创建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内容以下：

<? xml version="1.0" encoding="UTF-8" ?>
2

< beans
3

xmlns ="http://www.springframework.org/schema/beans"

xmlns:xsi ="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation ="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd" >

< bean id ="triggerUtil" class ="com.pro.base.util.TriggerUtil" >

</ bean >

< bean id ="expDataBaseJob"
12

class ="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean" >
13

< property name ="targetObject" >
14

< ref local ="triggerUtil" />
15

</ property >
16

< property name ="targetMethod" >
17

< value > expDataBase </ value >
18

</ property >
19

</ bean >
20

21

< bean id ="expDataBaseTrigger"
22

class ="org.springframework.scheduling.quartz.CronTriggerBean" >
23

< property name ="jobDetail" >
24

< ref local ="expDataBaseJob" />
25

</ property >
26

< property name ="cronExpression" >
27

< value > 00 33 21 * * ? </ value >

</ property >

</ bean >

< bean class ="org.springframework.scheduling.quartz.SchedulerFactoryBean" >
32

< property name ="triggers" >

< list >

< ref local ="expDataBaseTrigger" />
