org.postgresql.util.PSQLException：错误：关系“用户”不存在 - SpringBoot，Hibernate，Postgresql

Question

I am using Spring Boot with Hibernate, JPA and Postgresql database. I am trying to create new user and save it. I have the following code:

UserEntity.java

@NoArgsConstructor
@AllArgsConstructor
@ToString
@Getter
@Setter
@Entity(name = "Users")
public class UserEntity{

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private long id;

    @Column(nullable = false, unique = true)
    private String userId;
    @Column(nullable = false, length = 50)
    private String firstName;
    @Column(nullable = false, length = 50)
    private String lastName;
    @Column(nullable = false, length = 120, unique = true)
    private String email;
    @Column(nullable = false, unique = true)
    private String encryptedPassword;
}

UserController.java

@RestController
@RequestMapping("/users")
public class UserController {

    @Autowired
    UserService userService;

    private static final ModelMapper modelMapper = new ModelMapper();

    @PostMapping
    public ResponseEntity<CreateUserResponseModel> createUser(@Valid @RequestBody CreateUserRequestModel userDetails){

        modelMapper.getConfiguration().setMatchingStrategy(MatchingStrategies.STRICT);
        UserDto userDto = modelMapper.map(userDetails, UserDto.class);
        UserDto createdUser = userService.createUser(userDto);

        CreateUserResponseModel returnValue = modelMapper.map(createdUser, CreateUserResponseModel.class);
        return ResponseEntity.status(HttpStatus.CREATED).body(returnValue);
    }

}

UserServiceImpl.java

@Service
public class UserServiceImpl implements UserService{

    private final UserRepository userRepository;

    @Autowired
    public UserServiceImpl(UserRepository userRepository) {
        this.userRepository = userRepository;
    }

    private static final ModelMapper modelMapper = new ModelMapper();

    @Override
    @Transactional
    public UserDto createUser(UserDto user) {

        user.setUserId(UUID.randomUUID().toString());
        modelMapper.getConfiguration().setMatchingStrategy(MatchingStrategies.STRICT);
        UserEntity userEntity = modelMapper.map(user, UserEntity.class);
        userEntity.setEncryptedPassword("test");
        userRepository.save(userEntity);

        UserDto returnValue = modelMapper.map(userEntity, UserDto.class);

        return returnValue;
    }
} 

UserRepository.java

public interface UserRepository extends CrudRepository<UserEntity, Long> {

}

Application.yaml

I am testing it with Postman and sending JSON in body like this:

{
    "firstName": "Anna",
    "lastName": "Faranhay",
    "email": "Faranhay@gmail.com",
    "password": "ana1234"
}

But in Postman I am receiving 500 Internal Error.

Any advice appreciated.

Answer 1

For PostgreSQL you need to use GenerationType.SEQUENCE instead of GenerationType.IDENTITY.

Then:

@NoArgsConstructor
@AllArgsConstructor
@ToString
@Getter
@Setter
@Table(name = "Users")
@Entity
public class UserEntity {

    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE)
    private long id;

    @Column(nullable = false, unique = true)
    private String userId;
    @Column(nullable = false, length = 50)
    private String firstName;
    @Column(nullable = false, length = 50)
    private String lastName;
    @Column(nullable = false, length = 120, unique = true)
    private String email;
    @Column(nullable = false, unique = true)
    private String encryptedPassword;
}
