工程项目管理系统源码+功能清单+项目模块+spring cloud +spring boot em
由于提供的信息不足以准确回答,我将提供一个概括性的解答。
"spring cloud" 和 "spring boot" 是用于构建微服务的框架,"spring cloud" 是基于 "spring boot" 的。如果您想要一个示例,可以考虑创建一个简单的用户管理模块。
以下是一个简单的用户管理模块的代码示例:
// 用户实体
@Entity
public class User {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String username;
private String email;
// 省略getter和setter
}
// 用户服务接口
public interface UserService {
User createUser(User user);
User getUserById(Long id);
List<User> getAllUsers();
User updateUser(Long id, User user);
void deleteUserById(Long id);
}
// 用户服务实现
@Service
public class UserServiceImpl implements UserService {
@Autowired
private UserRepository userRepository;
@Override
public User createUser(User user) {
return userRepository.save(user);
}
@Override
public User getUserById(Long id) {
return userRepository.findById(id).orElse(null);
}
@Override
public List<User> getAllUsers() {
return userRepository.findAll();
}
@Override
public User updateUser(Long id, User user) {
User existingUser = userRepository.findById(id).orElseThrow(() ->
new UsernameNotFoundException("User not found with id: " + id));
existingUser.setUsername(user.getUsername());
existingUser.setEmail(user.getEmail());
return userRepository.save(existingUser);
}
@Override
public void deleteUserById(Long id) {
userRepository.deleteById(id);
}
}
// 用户控制器
@RestController
@RequestMapping("/users")
public class UserController {
@Autowired
private UserService userService;
@PostMapping
public ResponseEntity<User> createUser(@Valid @RequestBody User user) {
return new ResponseEntity<>(userService.createUser(user), HttpStatus.CREATED);
}
@GetMapping("/{id}")
public ResponseEntity<User> getUserById(@PathVariable("id") Long id) {
return ResponseEntity.ok(userService.getUserById(id));
}
