Spring集成Quartz

    像本文这种配置之后,启动Web应用,即便是只部署一个应用实例,也有可能定时任务被执行了两次
    这通常是由于 applicationContext.xml 被初始化两次导致,所以检查以下 web.xml 里面的配置就行了

本文涉及的相关环境和版本为:Spring-2.xQuartz-1.x

下面直接演示Spring集成Quartz实现作业调度功能的核心代码

首先是applicationContext.xml

<bean id="recfileQuartz" class="com.ecpay.cus.quartz.RecFileQuartz">
    <property name="pbcDao" ref="pbcDao"/>
    <property name="nauDao" ref="nauDao"/>
</bean>
<bean id="messageSendQuartz" class="com.ecpay.cus.quartz.MessageSendQuartz">
    <property name="jfbManager" ref="jfbManager"/>
</bean>

<!--
Spring作业调度
0 0/10 9-23 * * ? :每天09:00-23:00之间每10分钟触发一次
0 */2 * * * ?     :02分钟触发一次
0 30 0 * * ?      :每天00:30触发
0 0 1 * * ?       :每天01:00触发
0 0 0 1 * ?       :每月01号零点触发
autoStartup='true':SchedulerFactoryBean在初始化后是否马上启动Scheduler,默认true,若为false则需手工启动Scheduler
concurrent='false':false为不允许任务并发执行,即第二个job将不会在第一个job完成之前开始执行,默认的jobs是并行执行的
-->
<bean id="quartzJobFactory" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    <property name="triggers">
        <list>
            <ref bean="genRecFileRelationTrigger"/>
            <ref bean="sendInfoTrigger"/>
        </list>
    </property>
    <property name="autoStartup" value="true"/>
</bean>

<bean id="genRecFileRelationTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
    <property name="jobDetail" ref="genRecFileRelationJobDetail"/>
    <property name="cronExpression" value="0 30 0 * * ?"/>
</bean>
<bean id="genRecFileRelationJobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
    <property name="targetObject" ref="recfileQuartz"/>
    <property name="targetMethod" value="genRecFileRelation"/>
    <property name="concurrent" value="false"/>
</bean>

<bean id="sendInfoTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
    <property name="jobDetail" ref="sendInfoDetail"/>
    <property name="cronExpression" value="0 */10 * * * ?"/>
</bean>
<bean id="sendInfoDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
    <property name="targetObject" ref="messageSendQuartz"/>
    <property name="targetMethod" value="executeSend"/>
    <property name="concurrent" value="false"/>
</bean>

下面是MessageSendQuartz.java

package com.ecpay.cus.quartz;
import org.springframework.transaction.annotation.Transactional;
import com.ecpay.cus.service.JFBBusinessManager;

/**
 * 信息推送之作业调度类
 * Created by 玄玉<http://jadyer.cn/> on 2012/05/04 12:50.
 */
@Transactional
public class MessageSendQuartz {
    private JFBBusinessManager jfbManager;
    public void setJfbManager(JFBBusinessManager jfbManager) {
        this.jfbManager = jfbManager;
    }

    /**
     * 定时执行的方法
     */
    @Transactional
    public void executeSend() throws Exception {
        System.out.println("恭喜您:信息推送任务启动了");
    }
}

下面是RecFileQuartz.java

package com.ecpay.cus.quartz;
import org.springframework.transaction.annotation.Transactional;
import com.ecpay.cus.dao.NotActiveUserDAO;
import com.ecpay.cus.dao.PayBusinessCustomizeDAO;

/**
 * 业务定制对账文件之作业调度类
 * Created by 玄玉<http://jadyer.cn/> on 2012/05/04 12:50.
 */
@Transactional
public class RecFileQuartz {
    private PayBusinessCustomizeDAO pbcDao;
    private NotActiveUserDAO nauDao;
    public void setNauDao(NotActiveUserDAO nauDao) {
        this.nauDao = nauDao;
    }
    public void setPbcDao(PayBusinessCustomizeDAO pbcDao) {
        this.pbcDao = pbcDao;
    }

    /**
     * 生成定制关系到数据库
     */
    @Transactional
    public void genRecFileRelation() {
        System.out.println("恭喜您:Spring定制调度执行了该方法,本行打印的日志就是该方法的第一行代码");
    }
}
