添加配置：
全局URL拦截：
<mvc:interceptors>
<!-- 使用bean定义一个Interceptor，直接定义在mvc:interceptors根下面的Interceptor将拦截所有的请求 -->
<bean class="com.rhythmk.web1.filter.GlobalInterceptor" />
</mvc:interceptors>
指定规格URL拦截：
<mvc:interceptors>
<!-- 使用bean定义一个Interceptor，直接定义在mvc:interceptors根下面的Interceptor将拦截所有的请求 --> <mvc:interceptor>
<mvc:mapping path="/uic/*"/>
<!-- 定义在mvc:interceptor下面的表示是对特定的请求才进行拦截的 -->
<bean class="com.rhythmk.web1.filter.GlobalInterceptor"/>
</mvc:interceptor>
</mvc:interceptors>
