想让两个地址跳转的页面一样

<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>

(1)可在index.jsp页面中处理

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib uri="http://sf.com/taglib/sf-common" prefix="common"%>
<%
       String path = request.getContextPath();
       String basePath = request.getScheme() + "://"+ request.getServerName() + ":" + request.getServerPort()+ path + "/";

　　//加入下面语句

     response.sendRedirect("index.do"); // 同时后台代码sessionFilter不拦截此index.do

%>
