Spring+Quartz 整合一：常规整合

 步骤一： 定时任务需要一个配置文件（spring-mvc-timeTask.xml 随便起名），将其在web.xml中加载

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:spring-*.xml</param-value>
</context-param>

 

步骤二：编写调度任务配置文件spring-mvc-timeTask.xml ，一般包括三部分：定时器、触发器、调度器

    <!-- 定时任务配置 scheduler 方式 注解 暂时不支持动态更新 
    <context:component-scan base-package="org.jeecgframework.core.timer" />
    <task:executor id="executor" pool-size="5" />
    <task:scheduler id="scheduler" pool-size="10" />
    <task:annotation-driven executor="executor" scheduler="scheduler" />
    -->
    
     <!-- 定时器 -->
    <bean id="msgService" class="com.buss.timer.impl.MsgServiceImpl"/>
    <bean id="sendUAttenceMsgTaskJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <property name="targetObject" ref="msgService" />
        <property name="targetMethod" value="sendUAttenceMsg" />
        <property name="concurrent" value="true" />
    </bean>
    <!-- 触发器 -->
    <bean id="sendUAttenceMsgCronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
        <property name="jobDetail" ref="sendUAttenceMsgTaskJob" />
        <property name="cronExpression" value="0 0/1 * * * ?" />
    </bean>
    
    
    <!-- 定时器 -->
    <bean id="sendColoumeMsgTaskJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <property name="targetObject" ref="msgService" />
        <property name="targetMethod" value="sendColoumeMsg" />
        <property name="concurrent" value="true" />
    </bean>
    <!-- 触发器 -->
    <bean id="sendColoumeMsgCronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
        <property name="jobDetail" ref="sendColoumeMsgTaskJob" />
        <property name="cronExpression" value="0 0/1 * * * ?" />
    </bean>

    <!-- 调度器 -->
    <bean id="schedulerFactory" lazy-init="false" autowire="no" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
            <list>
                <ref bean="sendUAttenceMsgCronTrigger" />
                <ref bean="sendColoumeMsgCronTrigger" />
            </list>
        </property>
    </bean>

</beans>

 

 

步骤三：编写定时任务具体执行类：
两种方式：
方式一：继承org.springframework.scheduling.quartz.QuartzJobBean
方式二：是在配置文件里定义任务类和要执行的方法，类和方法可以是普通类。很显然，使用配置文件的目的就是要用这种方式。

 

注意： 在Spring配置和Quartz集成内容时，有两点需要注意

1、在<Beans>中不能够设置default-lazy-init="true",否则定时任务不触发，如果不明确指明default-lazy-init的值，默认是false。
2、在<Beans>中不能够设置default-autowire="byName"的属性，否则后台会报org.springframework.beans.factory.BeanCreationException错误，这样就不能通过Bean名称自动注入，必须通过明确引用注入
3、spring和quartz的整合对版本是有要求的。
spring3.1以下的版本必须使用quartz1.x系列，3.1以上的版本才支持quartz 2.x，不然会出错。
至于原因，则是spring对于quartz的支持实现，org.springframework.scheduling.quartz.CronTriggerBean继承了org.quartz.CronTrigger，在quartz1.x系列中org.quartz.CronTrigger是个类，而在quartz2.x系列中org.quartz.CronTrigger变成了接口，从而造成无法用spring的方式配置quartz的触发器（trigger）。
