spring 使用动态定时器quartz

需添加jar：quartz-all-1.8.5.jar

spring中的配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:p="http://www.springframework.org/schema/p" 
    xmlns:context="http://www.springframework.org/schema/context" 
    xmlns:tx="http://www.springframework.org/schema/tx" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans-2.5.xsd 
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context-2.5.xsd 
    http://www.springframework.org/schema/tx 
    http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">


    <!--spring集成quartz的定时器 -->
    <!-- 线程执行器配置，用于任务注册 -->
    <bean id="executor"    class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor">
        <property name="corePoolSize" value="10" />
        <property name="maxPoolSize" value="100" />
        <property name="queueCapacity" value="500" />
    </bean>
    <!-- 业务对象 -->
    <bean id="autoAudit" class="com.easipass.business.auto.AutoAudit" >
        <property name="scheduler" ref="schedulerFactory" /> 
    </bean>
    <!-- 调度业务 -->
    <bean id="jobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <property name="targetObject" ref="autoAudit" />
        <property name="targetMethod" value="doAutoAudit" />
    </bean>
    <!--增加调度触发器  -->
    <bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
        <property name="jobDetail" ref="jobDetail" />
        <property name="cronExpression" value="0 27 10 * * ?" />
    </bean>
    <!-- 设置调度 -->
    <bean id="schedulerFactory" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">  
        <property name="triggers">  
            <list>  
                <ref bean="cronTrigger" />  
            </list>  
        </property>  
    </bean>  
    
</beans>

调用方法：

 1 package com.easipass.business.auto;
 2 
 3 
 4 import javax.annotation.Resource;
 5 
 6 import org.apache.commons.logging.Log;
 7 import org.apache.commons.logging.LogFactory;
 8 import org.quartz.Scheduler;
 9 import org.springframework.scheduling.quartz.CronTriggerBean;
10 
11 import com.easipass.business.service.interfaces.IAutoAuditService;
12 import com.easipass.business.util.SysOptionsUtil;
13 
14 public class AutoAudit {
15     
16     @Resource(name="autoAuditService")
17     private IAutoAuditService autoAuditService ;
18     
19     private Log logger = LogFactory.getLog(getClass());
20     
21     private Scheduler scheduler;
22 
23     public void setScheduler(Scheduler scheduler) {
24     this.scheduler = scheduler;
25     } 
26     
27     
28     public void doAutoAudit()
29     {
30         try{
31             CronTriggerBean trigger = (CronTriggerBean) scheduler.getTrigger("cronTrigger", Scheduler.DEFAULT_GROUP);  
32             String dbCronExpression = SysOptionsUtil.getFinanceAuditTime();  
33             String originConExpression = trigger.getCronExpression();  
34             // 如果数据库中的定时器表达式和现有的一致，则不需要重新rescheduleJob  
35             if(!originConExpression.equalsIgnoreCase(dbCronExpression)){  
36                 trigger.setCronExpression(dbCronExpression);  
37                 scheduler.rescheduleJob("cronTrigger", Scheduler.DEFAULT_GROUP, trigger);  
38             }  
39             autoAuditService.autoAudit();
40             
41         }catch(Exception e){
42             logger.error("自动审核出错：",e);
43         }
44     }
45 
46 }

32行的SysOptionsUtil.getFinanceAuditTime()表示从数据库中读取的定时表达式。这样就可以从数据库动态读取了，如果定时需求发生变化就无需更改代码，只要成功起一下web服务即可。
