改进4.编写login.jsp文件
1 <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> 2 <% 3 String path = request.getContextPath(); 4 String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() 5 + path + "/"; 6 %> 7 8 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> 9 <html> 10 <head> 11 <base href="<%=basePath%>"> 12 13 <title>My JSP 'login.jsp' starting page</title> 14 15 <meta http-equiv="pragma" content="no-cache"> 16 <meta http-equiv="cache-control" content="no-cache"> 17 <meta http-equiv="expires" content="0"> 18 <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> 19 <meta http-equiv="description" content="This is my page"> 20 <!-- 21 <link rel="stylesheet" type="text/css" href="styles.css"> 22 --> 23 24 </head> 25 26 <body> 27 <form action="post" method="get"> 28 First name:<br> <input type="text" name="firstname"> <br> 29 Last name:<br> <input type="text" name="lastname"> 30 31 </form> 32 ${什么的干活} 33 34 </body> 35 </html>
