用java的Quartz包定時調用方法？

<bean id="simpleTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean">

<!-- see the example of method invoking job above -->

<property name="jobDetail" ref="jobDetail" />

<!-- 0 seconds -->

<property name="startDelay" value="0" />

<!-- repeat every 5400 seconds -->

<property name="repeatInterval" value="5400000" /> </bean>
