下面的是commonjsp的内容

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
    <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
<%
    String nameSpace = request.getContextPath();
%>
<%
    String projectPath = request.getScheme() + "://"
					+ request.getServerName() + ":" + request.getServerPort()
					+ nameSpace + "/";
%>
<c:set value="<%=projectPath %>" var="basePath"/>
