现在想要获得在特定时间或者指定时间执行相应功能
有两种做法
在applicationContext.xml中写入如下Bean
<bean id="repeatingTrigger"
   class="org.springframework.scheduling.timer.ScheduledTimerTask">
   <!--启动一秒后执行 -->
   <property name="delay">
    <value>1000</value>
   </property>
   <!--每隔一小时执行一次 -->
   <property name="period">
    <value>3600000</value>
   </property>
   <!--注入要监控的javaBean -->
   <property name="timerTask">
    <ref bean="task" />
   </property>
   <!--类型是否为fixedRate型，默认为fixedDelay-->
   <property name="fixedRate">
    <value>true</value>
   </property>


</bean>
<bean id="scheduler"
   class="org.springframework.scheduling.timer.TimerFactoryBean">
   <property name="scheduledTimerTasks">
    <list>
     <ref bean="repeatingTrigger" />
    </list>
   </property>
</bean>
