spring 整合 Quartz 實現動態任務調度

spring版本4.1.2和quartz 2.2.1整合，實現持久化到數據庫

先在spring中配置好scheduler；

<bean id="simpleJobListener" class="xxx.xxx.quartz.task.SimpleJobListener"/>
    <bean id="mapScheduler" lazy-init="false" autowire="no"
          class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="configLocation" value="classpath:conf/quartz.properties"/>
        <property name="globalJobListeners">
            <list>
　　　　　　　　　　<!-- job監聽器 -->
                <ref bean="simpleJobListener"/>
            </list>
        </property>
        <property name="triggers">
            <list>
　　　　　　　　　　<!-- 在這里配置定時任務調度器 -->
                <ref bean="testCornTrigger"/>
            </list>
        </property>
    </bean>

    <!-- 配置的JobDetai -->
    <bean id="testJobDetai" class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
        <!-- durability 表示任務完成之后是否依然保留到數據庫，默認false   -->
        <property name="durability" value="false" />
        <property name="jobClass" value="xxx.xxx.quartz.task.TestJob" />
    </bean>
    <!-- 配置的JobDetai，基於corn的調度器 -->
    <bean id="testCornTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="jobDetail" ref="testJobDetai"/>
        <!-- 每天23點執行一次 -->
        <property name="cronExpression" value="0 0 23 * * ?"/>
    </bean>
