首先在專案中新增interceptor-servlet.xml來配置攔截器，當然，必須在web.xml中配置在tomcat啟動時載入，如下：

 <!--1.配置spring分發器(是總的控制中心  被攔截的url會匯聚到該servlet) -->
	<servlet>
	    <servlet-name>springmvc</servlet-name>  
	    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
	    <!--配置spring上下文  (從該目錄下載入spring mvc的配置檔案) -->
	    <init-param>
	       <param-name>contextConfigLocation</param-name>
	       <param-value>/WEB-INF/classes/spring/*servlet.xml</param-value>
	    </init-param>
	    <load-on-startup>1</load-on-startup>  <!-- tomcat啟動後立即載入 -->
	</servlet>
 

interceptor-servlet.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

  <!-- 攔截器 -->
	<mvc:interceptors>
	    <!-- 多個攔截器,順序執行 -->
	    <!-- 攔截器1 登陸攔截 -->
	    <mvc:interceptor>
	       <mvc:mapping path="/login/login.do" /><!-- 可以寫多個，如果為/*,將攔截所有的Controller -->
	       <bean class="module.interceptor.LoginInterceptor">
