基于spring+quartz开发定时器

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:
 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
     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" ?>
 2 < beans
 3      xmlns ="http://www.springframework.org/schema/beans"
 4     xmlns:xsi ="http://www.w3.org/2001/XMLSchema-instance"
 5     xsi:schemaLocation ="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd" >
 6      <!--  定时器配置  -->
 7 <!--  配置定时器类  -->
 8    < bean  id ="triggerUtil"  class ="com.pro.base.util.TriggerUtil"   >
 9    </ bean >
10    <!--  指定任务(方法)  -->
11    < 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    <!--  设定计划执行时间  -->
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 >
28        </ property >
29        </ bean >
30        <!--  任务执行器配置  -->
31        < bean  class ="org.springframework.scheduling.quartz.SchedulerFactoryBean" >
32          < property  name ="triggers" >
33              < list >
34                  < ref  local ="expDataBaseTrigger"   />
35              </ list >
36          </ property >
37      </ bean >
38 </ beans >
