spring mvc 拦截器 拦截不到请求
拦截器继承和实现的类如下：
public class LoginInterceptor extends HandlerInterceptorAdapter 
implements InitializingBean 
并且实现了请求 前后的3个方法

web.xml 配置：
  <servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>

springmvc-servlet.xml 配置：
 <bean id="loginInterceptor" class="com.luse.web.interceptor.LoginInterceptor"/>  

<bean id="urlMapping"
  class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<!-- <property name="mappings"> -->
<!-- <props> -->
<!-- <prop key="/user/**">userController</prop> -->
<!-- </props> -->
<!-- </property> -->
  <property name="interceptors">
  <list>
  <ref bean="loginInterceptor" />
  </list>
  </property>
  </bean>

在这里不配置mappings 就是拦截所有请求， 现在一个也没拦截到

加了这个没
<!-- 配置spring的filter -->
<filter>
<filter-name>springSecurityFilterChain</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>

<filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
