对于JavaEE用户注册和登录界面的源码,可以参考以下示例代码:
注册页面代码:
```
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>用户注册</title>
</head>
<body>
<h1>用户注册</h1>
<form action="register" method="post">
<label>用户名:</label>
<input type="text" name="username" required><br>
<label>密码:</label>
<input type="password" name="password" required><br>
<label>确认密码:</label>
<input type="password" name="confirmPassword" required><br>
<input type="submit" value="注册">
</form>
</body>
</html>
```
登录页面代码:
```
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>用户登录</title>
</head>
<body>
<h1>用户登录</h1>
<form action="login" method="post">
<label>用户名:</label>
<input type="text" name="username" required><br>
<label>密码:</label>
<input type="password" name="password" required><br>
<input type="submit" value="登录">
</form>
</body>
</html>
```
JavaEE后端代码:
```
@WebServlet("/register")
public class RegisterServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String username = request.getParameter("username");
String password = request.getParameter("password");
String confirmPassword = request.getParameter("confirmPassword");
if (!password.equals(confirmPassword)) {
response.sendRedirect("register.jsp");
return;
}
// 将用户信息保存至数据库
response.sendRedirect("login.jsp");
}
}
@WebServlet("/login")
public class LoginServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String username = request.getParameter("username");
String password = request.getParameter("password");
// 从数据库中查询用户信息
if (用户名和密码验证通过) {
HttpSession session = request.getSession();
session.setAttribute("username", username);
response.sendRedirect("index.jsp");
} else {
response.sendRedirect("login.jsp");
}
}
}
```
以上代码仅为示例,请根据实际情况进行修改和完善。
