JavaBean技术与JSP开发模型（用户登录页面的实现）

JavaBean种类

1.在IDEA中创建一个名称为chapter06的Web项目，在src文件夹中创建名称为cn.itcast的包，并在包中创建名称为User的JavaBean对象，用于封装用户信息，具体代码如下

package entity;

public class User {
    private String username;
    private String password;
    private String name;
    private String email;
    private String phone;
    private String address;
    private String isadmin;

    public User() {
    }

    public User(String username, String password, String name, String email, String phone, String address,String isadmin) {
        this.username = username;
        this.password = password;
        this.name = name;
        this.email = email;
        this.phone = phone;
        this.address = address;
        this.isadmin = isadmin;
    }

    //setter and getter
    public String getIsadmin() {
        return isadmin;
    }

    public void setIsadmin(String isadmin) {
        this.isadmin = isadmin;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }
}

2.在项目中的web文件夹下创建名称为login的JSP文件，该用户用于输入并提交用户名和密码。代码的实现如下


<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<head>
    <meta charset="UTF-8">
    <title>用户登录页面</title>
    <link type="text/css" rel="stylesheet" href="css/bootstrap.css">
    <link type="text/css" rel="stylesheet" href="css/style.css">
    <!--    <link type="text/css" rel="stylesheet" href="css/flexslider.css">-->
    <script src="js/jquery-3.6.0.js"></script>
    <script src="js/bootstrap.js"></script>
</head>
<body>
<%--导航栏页面--%>
<%@include file="header.jsp" %>
<%--注册部分--%>
<div class="account">
    <div class="container">
        <div class="register">
            <form action="<%=request.getContextPath()%>/user_login" method="post">
                <div class="register-top-grid">
                    <h3>用户登录</h3>
                    <div class="input">
                        <label for="username" >用户名：<label style="color: red">*   ${ sessionScope.loginmsg } </label></label>
                        <input type="text" name="username" id="username" placeholder="请输入用户名" required="required">
                    </div>
                    <div class="input">
                        <label for="psd" >密码：<label style="color: red">*</label></label>
                        <input type="password" name="password" id="psd" placeholder="请输入用户名" required="required">
                    </div>
                </div>
                <div class="register-but text-center">
                    <input type="submit" value="登录">
                    <div class="clearfix"></div>
                </div>
            </form>
            <div class="clearfix"></div>
        </div>
    </div>
</div>
<%--底部信息页面--%>
<%@include file="footer.jsp"%>
</body>
</html>
