基于Javaweb的网上购物商城系统源码,用jsp+servlet+jQuery
由于提供整个网上购物系统的源代码超出了问答的字数限制,我将提供一个简化版的用户注册功能作为示例。这个示例使用JSP、Servlet和jQuery来实现用户注册的后端逻辑。
UserRegisterServlet.java (Servlet部分)
@WebServlet("/user/register")
public class UserRegisterServlet extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String username = request.getParameter("username");
String password = request.getParameter("password");
// 在实际应用中,这里应该是对用户信息的持久化存储逻辑,例如保存到数据库中
// 为了简化,这里仅打印用户名和密码
System.out.println("Registered user: " + username);
// 设置响应内容类型
response.setContentType("application/json");
PrintWriter out = response.getWriter();
// 返回JSON格式的响应
out.print("{\"status\":\"success\", \"message\":\"User registered successfully!\"}");
out.flush();
}
}
register.jsp (JSP部分)
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>User Registration</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
$(document).ready(function() {
$('#registerForm').submit(function(e) {
e.preventDefault();
$.ajax({
url: '/user/register',
type: 'POST',
data: $(this).serialize(),
success: function(response) {
alert(response.message);
// 可以根据需要跳转到登录页面或者其他页面
// window.location.href = '/login';
},
error: function() {
alert('An error occurred. Please try again later.');
}
});
});
});
</script>
</head>
<body>
<form id="registerForm">
<label for="username">Username:</label>
<input type="text" id="username" name="username" required><br>
<label f
