javaEE项目中常用的包含上下文路径的代码

<%@page import="java.util.regex.*" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>
<%@page import="com.uudev.framework.util.LoggerUtils" %>
<%@page import="com.uudev.framework.util.Utils" %>
<%
//设置contextPath上下文路径
String contextPath = Utils.getContextPath(request);
//LoggerUtils.getLogger().warn("contextPath="+contextPath);
String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + contextPath + "/";
request.setAttribute("contextPath", contextPath);
%>
<script>
contextPath = '<%=contextPath %>';
jsessionid = '<%=request.getSession().getId() %>';
</script>
