spring的quartz定时任务

一、版本：

　　1.spring：4.1.7；

　   2.quartz：2.2.1；

二、基于ssm项目：

1.引入jar包：quartz-2.2.1.jar；spring所需包。

2.说明：quartz版本和spring版本要兼容，低版本的quartz集成在高版本的spring中会报错：java.lang.ClassNotFoundException: org.quartz.impl.JobDetailImpl。

　　其实在spring4.1.x的源码中已经有对应的说明了，原文如下：

Compatible with Quartz 2.1.4 and higher, as of Spring 4.1. 

3.常见异常原因ClassNotFoundException: org.springframework.scheduling.quartz.CronTriggerBean：

在quartz 1.8.6及以前版本的时候 调度触发器 依赖的类是 org.springframework.scheduling.quartz.CronTriggerBean

在2.xx版本之后就改为了org.springframework.scheduling.quartz.CronTriggerFactoryBean

因此当你依赖2.x.x版本之后只需将调度触发器的依赖类改为 org.springframework.scheduling.quartz.CronTriggerFactoryBean即可

三、代码：

quartz文件配置applicationContext-quartz.xml：

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

    <!-- quartz定时任务 -->
    <!-- <bean id="marketTest" class="com.test.www.web.timeTask.MarketMaintainEmailRemind">

    </bean> -->
      <!--第四步 把定义好的任务放到调度（Scheduler）工厂里面,注意这里的ref bean -->
    <bean id="schedulerFactoryBean3"
        class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="applicationContextSchedulerContextKey" value="applicationContext"/>
        <property name="triggers">
            <list>
                <ref bean="printTimerTrigger10" />
            </list>
        </property>
    </bean>
    <!-- CronTriggerBean -->
    <bean id="printTimerJob10"
        class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <property name="targetObject" ref="marketMaintainEmailRemind" />  <!-- marketMaintainEmailRemind marketTest -->
        <property name="targetMethod" value="run" />
        <property name="concurrent" value="false"/>
    </bean>
    <bean id="printTimerTrigger10" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="jobDetail" ref="printTimerJob10" />
        <property name="cronExpression" value="0 54 12 * * ?" />
    </bean>

</beans>

在spring的配置文件applicationContext.xml中引入配置文件applicationContext-quartz.xml：

<import resource="applicationContext-quartz.xml" />

定时类：

package com.test.www.web.timeTask;

import javax.annotation.Resource;

import org.springframework.stereotype.Component;

import com.test.www.util.PrimaryKeyGenerator;
import com.test.www.web.entity.user.User;
import com.test.www.web.service.user.UserService;

//注：MarketMaintainEmailRemind类注册bean默认名称为类名且首字母小写，可通过注解方式自定义名称修改bean名称
@Component //@Service("marketTest")  @Component("marketTest")
public class MarketMaintainEmailRemind {
    @Resource
    private UserService userService;

    public void run() {

        try {
            System.out.println("aa");
            User user = new User();
            user.setId(PrimaryKeyGenerator.getLongKey());
            user.setUsername("定时任务Test");
            user.setPassword("dingshirenwuTest");
            userService.insertUser(user);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}

完成后，设定quartz中的时间，等待触发。时间一到就会执行MarketMaintainEmailRemind中的run方法。执行结果如下图所示：
