Spring+Quartz 整合一：常規整合

 步驟一： 定時任務需要一個配置文件（spring-mvc-timeTask.xml 隨便起名），將其在web.xml中加載

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

 

步驟二：編寫調度任務配置文件spring-mvc-timeTask.xml ，一般包括三部分：定時器、觸發器、調度器

    <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" />
    -->
    
     <!-- 定時器 -->
    <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>
    <!-- 觸發器 -->
    <bean id="sendUAttenceMsgCronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
        <property name="jobDetail" ref="sendUAttenceMsgTaskJob" />
        <property name="cronExpression" value="0 0/1 * * * ?" />
    </bean>
    
    
    <!-- 定時器 -->
    <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>
    <!-- 觸發器 -->
    <bean id="sendColoumeMsgCronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
        <property name="jobDetail" ref="sendColoumeMsgTaskJob" />
        <property name="cronExpression" value="0 0/1 * * * ?" />
    </bean>

    <!-- 調度器 -->
    <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>

 

 

步驟三：編寫定時任務具體執行類：
兩種方式：
方式一：繼承org.springframework.scheduling.quartz.QuartzJobBean
方式二：是在配置文件里定義任務類和要執行的方法，類和方法可以是普通類。很顯然，使用配置文件的目的就是要用這種方式。

 

注意： 在Spring配置和Quartz集成內容時，有兩點需要注意

1、在<Beans>中不能夠設置default-lazy-init="true",否則定時任務不觸發，如果不明確指明default-lazy-init的值，默認是false。
2、在<Beans>中不能夠設置default-autowire="byName"的屬性，否則后台會報org.springframework.beans.factory.BeanCreationException錯誤，這樣就不能通過Bean名稱自動注入，必須通過明確引用注入
3、spring和quartz的整合對版本是有要求的。
spring3.1以下的版本必須使用quartz1.x系列，3.1以上的版本才支持quartz 2.x，不然會出錯。
至於原因，則是spring對於quartz的支持實現，org.springframework.scheduling.quartz.CronTriggerBean繼承了org.quartz.CronTrigger，在quartz1.x系列中org.quartz.CronTrigger是個類，而在quartz2.x系列中org.quartz.CronTrigger變成了接口，從而造成無法用spring的方式配置quartz的觸發器（trigger）。
