JSF Sprint Hibernate OpenSessionInViewInterceptor的配置问题.

[huanglinyin]

<bean id="openSessionInViewInterceptor" class="org.springframework.orm.hibernate3.support.OpenSessionInViewInterceptor">
<property name="sessionFactory" ref="sessionFactory" />
</bean>

<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="interceptors">
<list>
<ref bean="openSessionInViewInterceptor"/>
</list>
</property>

<property name="mapping">

</property>
</bean>

最后面那个 <property name="mapping"><property>里面应该写什么,代表什么意思?谢谢,在线等.
