作为AI语言模型,我无法提供界面设计。但是,以下是一个简单的Spring Boot注册和登录示例,可以作为参考:
1. 创建一个 User 实体类
```java
@Entity
@Table(name = "users")
public class User {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String username;
private String password;
private String email;
// getter和setter方法
}
```
2. 创建 UserRepository 接口
```java
@Repository
public interface UserRepository extends JpaRepository<User, Long> {
User findByUsername(String username);
}
```
3. 创建 UserService 接口和实现类
```java
public interface UserService {
void save(User user);
User findByUsername(String username);
}
@Service
public class UserServiceImpl implements UserService {
@Autowired
private UserRepository userRepository;
@Override
public void save(User user) {
userRepository.save(user);
}
@Override
public User findByUsername(String username) {
return userRepository.findByUsername(username);
}
}
```
4. 创建控制器
```java
@Controller
public class AuthController {
@Autowired
private UserService userService;
@GetMapping("/register")
public String showRegistrationForm(Model model) {
model.addAttribute("user", new User());
return "registration";
}
@PostMapping("/register")
public String registerUser(@ModelAttribute("user") User user, BindingResult bindingResult) {
if (bindingResult.hasErrors()) {
return "registration";
}
userService.save(user);
return "redirect:/login";
}
@GetMapping("/login")
public String showLoginForm() {
return "login";
}
}
```
5. 创建 registration.html 和 login.html 页面
registration.html
```html
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Registration</title>
</head>
<body>
<h2>Registration</h2>
<form action="#" th:action="@{/register}" th:object="${user}" method="post">
<div>
<label for="username">Username:</label>
<input type="text" id="username" th:field="*{username}">
</div>
<div>
<label for="password">Password:</label>
<input type="password" id="password" th:field="*{password}">
</div>
<div>
<label for="email">Email:</label>
<input type="email" id="email" th:field="*{email}">
</div>
<button type="submit">Register</button>
</form>
</body>
</html>
```
login.html
```html
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Login</title>
</head>
<body>
<h2>Login</h2>
<form action="#" method="post">
<div>
<label for="username">Username:</label>
<input type="text" id="username" name="username">
</div>
<div>
<label for="password">Password:</label>
<input type="password" id="password" name="password">
</div>
<button type="submit">Login</button>
</form>
</body>
</html>
```
以上示例是一个简单的注册和登录示例,仅供参考。实际应用中,需要考虑更多的安全性和用户体验问题。
