<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://" + request.getServerName()
+ ":" + request.getServerPort() + path + "/";
String path = request.getContextPath();
String basePath = request.getScheme() + "://" + request.getServerName()
+ ":" + request.getServerPort() + path + "/";
%>
${pageContext.request.contextPath}
測試的案例index.jsp:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path + "/"; %> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> <%out.println(basePath);%> <br> <% out.println(path); %> <br> ${pageContext.request.contextPath} </body> </html>
