思路:创建登入界面(login),再创建登入成功与登入失败界面(loginsuccess与loginfail),再创建注册成功界面(registersuccess)与注册界面(register)以及总控制文件(check)通过form标签的action将他们连接起来。

第一步

首先我们来看看效果

登入界面(login)

javajsp注册页面 jsp用户注册界面_windows

登入成功与登入失败(loginsuccess与loginfail)

javajsp注册页面 jsp用户注册界面_javajsp注册页面_02


javajsp注册页面 jsp用户注册界面_javajsp注册页面_03

注册界面(register)

javajsp注册页面 jsp用户注册界面_windows_04

注册成功(registersuccess)

javajsp注册页面 jsp用户注册界面_javajsp注册页面_05

第二步

创建项目,再添加框架支持,把文件全部创建到通一个目录里面,新建image文件夹,放入我们的背景图片(可爱的小姐姐),如图:

javajsp注册页面 jsp用户注册界面_html5_06

在login文件写入

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
  <head>
    <title>登入界面</title>
  </head>
  <body>
  <h1>登录界面</h1>
  <form method="post" action="check.jsp">
    <input type="text" name="user"><br>
    <input type="password" name="pass"><br>
    <button type="submit" value="login">登入</button>
    <a href="register.jsp">注册</a>
  </form>
  </body>
</html>

在register文件写入

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
<h2>注册界面</h2>
    <form method="post" action="registersuccess.jsp">
    请输入您的用户名:<input type="text" name="user" size="20"><br>
    请输入您的密码:<input type="password" name="pass" size="20"><br>
    <button type="submit" value="login">注册</button>
    <button type="reset" value="reset">重置</button>
</form>
</body>
</html>

在registersuccess文件写入

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
<form method="post" action="check.jsp">

<%
    String user = "a";
    String pass = "b";
    if(request.getParameter("user")!=null && request.getParameter("pass") != null)
    {
        user = request.getParameter("user");
        session.setAttribute("user",user);
        pass = request.getParameter("pass");
        session.setAttribute("pass",pass);
    }

%>
<h2>恭喜您注册成功!</h2><br>
您的用户名是:<%=user%> <br>
您的密码是:<%=pass%>
</form>
<a href="login.jsp">返回登录界面</a>
</body>
</html>

在loginsuccess文件写入

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
<h2 align="center">登录成功</h2>
</body>
</html>

在loginfail文件写入

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
<h2 align="center">登录失败</h2>
<h3 align="center"><a href="login.jsp" style="color:#FAAF46; font-size:10px">返回登录页面</a></h3>
</body>
</html>

在check文件写入

<form method="post" action="">
    <%
        String user=(String)session.getAttribute("user");
        String pass=(String)session.getAttribute("pass");
        String name=request.getParameter("user");
        session.setAttribute("name", name);
        String password1=request.getParameter("pass");
        session.setAttribute("password", password1);
        if(user.equals(name)&&password1.equals(pass))
        { response.sendRedirect("loginsuccess.jsp");}
        else
            response.sendRedirect("loginfail.jsp");
    %>
</form>
</body>
</html>

那么我们来看看效果:

javajsp注册页面 jsp用户注册界面_css3_08


javajsp注册页面 jsp用户注册界面_html5_09

巨丑无比

第三步

我们加点css美化一下:

在login文件加入(字体居中效果,背景图片,按钮的透明度,输入框的透明度等)

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>注册失败界面</title>
    <style type="text/css">
        .center{
            text-align:center;
            margin-top: 50px;
        }
        .fon{
            font-size: 40px;
        }
        .fon1{
            font-size: 20px;
        }
        body{
            background: url("images/wallhaven-wqrm7r.jpg");
            background-size: 100% 100%;
        }
        input {
            background-color: transparent;
            outline: none;
            color: black;
        }

    </style>
</head>
<body>
<h2></h2>


<div class="center">
    <p class="fon">注册失败界面</p>
    <p class="fon1">对不起,您输入的有误,请返回注册界面</p>
    <a href="register.jsp">返回注册界面</a>
</div>

</body>
</html>

在loginsuccess文件加入(字体居中效果,背景图片)

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>登入成功界面</title>
    <style type="text/css">
        .center{
            text-align:center;
            margin-top: 50px;
        }
        .fon{
            font-size: 40px;
        }
        body{
            background: url("images/wallhaven-wqrm7r.jpg");
            background-size: 100% 100%;
        }
        input {
            background-color: transparent;
            outline: none;
            color: black;
        }

    </style>
</head>
<body>
<div class="center">
    <p class="fon">登入成功界面</p>
    <p class="fon1">恭喜您成功登入,欢迎使用</p>
</div>
</body>
</html>

在loginfail文件加入(字体居中效果,背景图片)

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>登入失败界面</title>
    <style type="text/css">
        .center{
            text-align:center;
            margin-top: 50px;
        }
        .fon{
            font-size: 40px;
        }
        body{
            background: url("images/wallhaven-wqrm7r.jpg");
            background-size: 100% 100%;
        }
        input {
            background-color: transparent;
            outline: none;
            color: black;
        }
    </style>
</head>
<body>
<div class="center">
    <p class="fon">登入失败界面</p>
    <p class="fon1">对不起,您账号或密码有误,请返回登入界面</p>
    <a href="login.jsp">返回登入界面</a>
</div>
</body>
</html>

在register文件加入(字体居中效果,背景图片,按钮的透明度,输入框的透明度等)

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>注册界面</title>
    <style type="text/css">
        .center{
            text-align:center;
            margin-top: 50px;
        }
        .fon{
            font-size: 40px;
        }
        body{
            background: url("images/wallhaven-wqrm7r.jpg");
            background-size: 100% 100%;
        }
        input {
            background-color: transparent;
            outline: none;
            color: black;
        }
        .clear{
            opacity:0.3;
        }
    </style>
</head>
<body>

<div class="center">
    <p class="fon">注册界面</p>
    <p>请输入您的用户名和密码进行注册</p>
    <form method="post" action="registersuccess.jsp">
        用户名:<input type="text" name="user"  name="user" style="width: 300px;height: 50px" placeholder="请输入用户名:" > <br>
        密码:    <input type="password" name="pass"  name="user" style="width: 300px;height: 50px" placeholder="请输入密码:" > <br>
        <button type="submit" style="width:80px;height:40px; font-size: 20px" class="clear">注册</button>
        <button type="reset" style="width:80px;height:40px; font-size: 20px" class="clear">重置</button>
        <br>
    </form>
</div>
</body>
</html>

在registersuccess文件加入(字体居中效果,背景图片)

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>注册成功界面</title>
    <style type="text/css">
        .center{
            text-align:center;
            margin-top: 50px;
        }
        .fon{
            font-size: 40px;
        }
        .fon1{
            font-size: 20px;
        }
        body{
            background: url("images/wallhaven-wqrm7r.jpg");
            background-size: 100% 100%;
        }
        input {
            background-color: transparent;

</head>
<body>
<form method="post" action="check.jsp">
    <%
        String user = null;
        String pass = null;
        if(request.getParameter("user")!=null && request.getParameter("pass") != null)
        {
            user = request.getParameter("user");
            session.setAttribute("user",user);
            pass = request.getParameter("pass");
            session.setAttribute("pass",pass);
        }
    %>

    <div class="center">
        <p class="fon">注册成功界面</p>
        <p class="fon1">恭喜您已经注册成功 !</p>
        <p class="fon1">您的用户名是:<%=user%></p>
        <p class="fon1">您的密码是:<%=pass%></p>
        <a href="login.jsp">返回登入界面</a>
    </div>

</form>
</body>
</html>

check不变

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>检查界面</title>
</head>
<body>

<form method="post" action="">

    <%
        String user = (String) session.getAttribute("user");
        String pass = (String) session.getAttribute("pass");
        String user1 = request.getParameter("user");
        session.setAttribute("user1",user1);
        String pass1 = request.getParameter("pass");
        session.setAttribute("pass1",pass1);

        if (user.equals(user1) && pass.equals(pass1)) {
            response.sendRedirect("loginsuccess.jsp");
        }
        else {
            response.sendRedirect("loginfail.jsp");
        }
    %>
</form>
</body>
</html>

(编辑好配置)点击运行效果就出来了。

(求关注)写代码写的好累啊,今天八节课,写代码写博客写到22点了,洗澡去了。
后面会更新android,jquery,jsp,蓝桥杯等等。
