我是靠谱客的博主热心草莓，最近开发中收集的这篇文章主要介绍JSP实现简单的用户登录，并显示出用户的信息，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

<%@ page language="java" import="java.util.*" pageEncoding="GB18030"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
  </head>
  
  <body>
  <form action="login_success.jsp" method = "post">
   用户名：<input type ="text" name = "username"/><br>
   密码：<input type = "password" name ="password"><br>
   <input type ="submit" value="提交"/> 
   </form>
  </body>
</html>

login_success.jsp 用于显示用户信息

<%@ page language="java" import="java.util.*" pageEncoding="GB18030"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
  </head>
  
  <body>
  <%
  String uname = request.getParameter("username");
  String pwd = request.getParameter("password");
  out.println(uname);
  out.println(pwd);
   %>
  </body>
</html>
