RestControllerAdvice 没有在邮递员中显示自定义异常

Question

我在一个单独的模块中创建了一个自定义异常句柄，并希望在另一个模块中使用相同的 GlobalExceptionHandle 类。虽然控制台上出现异常，但是邮递员上没有出现自定义异常。这可能是什么原因？请帮助我

GlobalExceptionHandle.java

@RestControllerAdvice
@Order(Ordered.HIGHEST_PRECEDENCE)
public class GlobalExceptionHandle extends ResponseEntityExceptionHandler {

    @ExceptionHandler(NotFoundException.class)
    public ResponseEntity<CustomExceptionResponseDto> handle(NotFoundException exception) {
        return new ResponseEntity<CustomExceptionResponseDto>(
                CustomExceptionResponseDto.builder()
                        .errorCode(HttpStatus.NOT_FOUND)
                        .message(exception.getMessage())
                        .status(HttpStatus.NOT_FOUND.value())
                        .timestamp(LocalDateTime.now())
                        .build(), HttpStatus.NOT_FOUND
        );
    }

    @ExceptionHandler(InvalidStateException.class)
    public ResponseEntity<CustomExceptionResponseDto> handle(InvalidStateException exception) {
        return new ResponseEntity<CustomExceptionResponseDto>(
                CustomExceptionResponseDto.builder()
                        .errorCode(HttpStatus.BAD_REQUEST)
                        .message(exception.getMessage())
                        .status(HttpStatus.BAD_REQUEST.value())
                        .timestamp(LocalDateTime.now())
                        .build(), HttpStatus.BAD_REQUEST
        );
    }
}

UserController.java

@RestController
@RequestMapping("/user")
@RequiredArgsConstructor
public class UserController {

    private final UserService userService;

    @PostMapping
    public ResponseEntity<UserResponseDto> save(@RequestBody UserRequestDto userRequestDto) {
        return ResponseEntity.ok(userService.save(userRequestDto));
    }
}

UserServiceImpl.java

@Service
@RequiredArgsConstructor
@Slf4j
public class UserServiceImpl implements UserService {

    private final UserRepository userRepository;
    private final UserMapper userMapper;
    private final BCryptPasswordEncoder bCryptPasswordEncoder;

    @Override
    public UserResponseDto save(UserRequestDto userRequestDto) {
        log.info("User request dto: " + userRequestDto);

        userRepository.findUserByEmail(userRequestDto.getEmail()).ifPresent((user) -> {
            throw new EmailAlreadyUseException(user.getEmail());
        });

        var user = userMapper.userRequestDtoToUser(userRequestDto);
        user.setPassword(bCryptPasswordEncoder.encode(userRequestDto.getPassword()));
        return userMapper.userToUserResponseDto(userRepository.save(user));
    }

}

InvalidStateException.java

public class InvalidStateException extends RuntimeException {

    private static final long serialVersionUID = 1L;

    public InvalidStateException(String message) {
        super(message);
    }
}

EmailAlreadyUseException.java

public class EmailAlreadyUseException extends InvalidStateException {
    public EmailAlreadyUseException(String email) {
        super(email+" already registered,try different email");
    }
}

我看到你正在抛出 throw new EmailAlreadyUseException(user.getEmail()); 但你处理 @ExceptionHandler(InvalidStateException.class) 尝试更改为@ExceptionHandler(EmailAlreadyUseException.class) 并检查一下。
