Spring项目 使用quartz定时执行任务

<!--执行任务类--->
<bean id="aaa" class="com.xxx.timing.test.timing"></bean> 
<!--配置定时任务-->
<bean id ="compareJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
	<property  name ="targetObject"  ref ="aaa"/> 
	     <property  name ="targetMethod"  value ="run"/> 
	<property  name ="concurrent"  value ="false"/> 
</bean>
<bean  id ="compareTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean"> 
	<property  name ="jobDetail"  ref ="compareJob"   /> 
	     <property  name ="cronExpression" >
        <!--没5秒执行一次-->              
	     <value>*/5 * * * * ?</value> 
	</property > 
</bean >
     
<bean id ="schedulerFactory" class="org.springframework.scheduling.quartz.SchedulerFactoryBean" > 
	<property name ="triggers" > 
	     <list >                     
	        <ref local ="compareTrigger"/> 
	     </list > 
	</property > 
</bean >

package com.xxx.timing.test;

        System.out.println("\t\t" + new Date(ms));
