spring定时器设定时间的问题

Question

我要每个星期的周六晚上23：59分调用一个action。以前没用过，在网上看那个时间规则看半天也不懂。自己写出来一个，一启动就报错。谁来帮我解决一下啊

<bean id="weekLsPlayerTaskAction"
    class="com.peuo.wl.task.WeekLsPlayerTaskAction"/>

<bean id="weekLsPlayerTaskActionTask"
     class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
     <property name="targetObject">
         <ref bean="weekLsPlayerTaskAction"/>
     </property>
     <property name="targetMethod">
         <value>doRun</value>
     </property>
</bean>

<bean id="weekLsPlayerActionTrigger"
      class="org.springframework.scheduling.quartz.CronTriggerBean">
      <property name="jobDetail">
          <ref bean="weekLsPlayerTaskActionTask"/>
      </property>
      <property name="cronExpression">
          <!-- 每周六晚上23:55执行 -->
          <value>0 55 23 * * 6</value>
      </property>
</bean>

 <bean autowire="no"
    class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    <property name="triggers">
        <list>
            <ref local="dayReportTaskActionTrigger" />
            <ref local="weekLsPlayerActionTrigger"/>
        </list>
    </property>
</bean>
