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:
login.jsp
<%@ 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>
希望本文所述对大家的jsp程序设计有所帮助。
