jsp页面路径问题

jsp路径默认不是项目跟路径

一、

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path + "/";
%>

<!doctype html>
<html>
<head>
 <base href="<%=basePath%>"> --------------------加入base，以后默认都是项目跟路径
<meta charset="utf-8">
<title>大客户网络维护管理系统</title>
<jsp:include page="common/header.jsp"/>

    <script type="text/javascript" src="app/js/video/video.js"></script>
</head>

二、每个都设置绝对路径

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

<c:set var="ctx" value="${pageContext.request.contextPath}"        ---------------绝对路径
    scope="request" />
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1">
<title>漂亮的easyui后台框架演示-css后台模板-www.16sucai.com</title>
<link href="${ctx}/app/easyui/css/default.css" rel="stylesheet"          --------------绝对路径
    type="text/css" />
<link rel="stylesheet" type="text/css"
    href="${ctx}/app/easyui/js/themes/default/easyui.css" />
<link rel="stylesheet" type="text/css"
    href="${ctx}/app/easyui/js/themes/icon.css" />
<script type="text/javascript"
    src="${ctx}/app/easyui/js/jquery-1.4.2.min.js"></script>
<script type="text/javascript"
    src="${ctx}/app/easyui/js/jquery.easyui.js"></script>

<script type="text/javascript" src='${ctx}/app/easyui/js/outlook2.js'> </script>

三、上述两者可以结合使用

<base href="${pageContext.request.contextPath}">
