在jsp界面中经常需要引入js、css等文件,通常都需要先获取项目根路径,然后再引入文件。
例如:
项目路径如下,需要在index.jsp中引入FusionCharts相关的js、css等;
index.jsp
<%@ page language="java" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path + "/";
response.setHeader("Pragma", "no-cache");
response.setHeader("Cache-Control", "no-cache");
response.setDateHeader("Expires", 0);
%>

<script type="text/javascript" src="<%=basePath%>fusionCharts/fusioncharts.js"></script>

<link rel="stylesheet" type="text/css" href="<%=basePath%>css/uploadify.css"/>
