spring 拦截器配置

<mvc:interceptors>
    <!--    后台是否有权限的拦截器s -->
        <mvc:interceptor>
            <!-- 需要被拦截的路径 -->
            <mvc:mapping path="/admin/**" /> 
            <!-- 不需要被拦截的路径 -->
            <mvc:exclude-mapping path="/admin/login"></mvc:exclude-mapping>
            <mvc:exclude-mapping path="/admin/logout"></mvc:exclude-mapping>
            <mvc:exclude-mapping path="/admin/index"></mvc:exclude-mapping>
            <mvc:exclude-mapping path="/admin/unauthorized"></mvc:exclude-mapping>
            <mvc:exclude-mapping path="/admin/edit_password"></mvc:exclude-mapping>
            <!-- 拦截处理的interceptor -->
            <bean class="com.pbh.aop.PermissionInterceptor">
            </bean>
        </mvc:interceptor>
</mvc:interceptors> 

注：mvc:exclude-mapping 标签不被spring-mvc-3.0.xsd支持，该配置在spring-mvc-3.2.xsd以上版本中
