quartz与spring配置

<!-- 实现规则服务实时加载的定时服务配置文件 -->

       <!--

       <property name="cronExpression"> 
           <value>0 0 21 * * ?</value> 
       </property> 
    </bean> 
     
    <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">

                <ref bean="cronTrigger" /> 
            </list> 
        </property> 
    </bean> 
</beans> 


id="loadObject"是定时服务类；
name="jobDetailBean"用来指定定时服务的方法；
id="cronTrigger"配置定时服务的时间；
最后一个bean用来设置定时服务队列。
（解释比较直白）
