本文实例讲述了JSP实现简单的用户登录并显示出用户信息的方法。分享给大家供大家参考。具体实现方法如下：

复制代码代码如下:

<%@ 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

复制代码代码如下:

<%@ 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>
