<!--1.简单定时-->
< bean id = " myTask "   class = " usish.po.pub.MyTask " >     <!--自己定义的任务extends TimerTask -->
   < property name = " generatPo " >
     < ref local = " generatPO " />
   </ property >
   < property name = " importData " >
     < ref local = " importData " />
   </ property >
</ bean >

< bean id = " timer "   class = " org.springframework.scheduling.timer.TimerFactoryBean " >
   < property name = " scheduledTimerTasks " >
     < list >
       < ref local = " scheduledTimerTask_1 " /> <!--定时器的任务链-->
     </ list >
   </ property >
</ bean >

< bean id = " scheduledTimerTask_1 "   class = " org.springframework.scheduling.timer.ScheduledTimerTask " > <!--任务链启动任务-->
   < property name = " timerTask " >
     < ref local = " myTask " />
   </ property >
   < property name = " delay " >
     < value > 1000 </ value >
   </ property >
   < property name = " period " >
     < value > 50000 </ value >
   </ property >
</ bean >

<!--2.使用Quartz定时-->
<!-- scheduler -->

 <bean id="cacheClearStarJob"
     class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">

            <value>clear</value>
        </property>
 </bean>
    <bean id="cacheClearStarTrigger"

        <property name="jobDetail">
            <ref local="cacheClearStarJob" />
        </property>
        <property name="cronExpression">

        </property>
  </bean>
