Я картирую три объекта.Доктор, Клиент (который расширяет лицо) и Медицинская консультация.Смотрите мой код выше.Рассмотрим все модели класса с конструктором по умолчанию, конструктор со всеми полями, а также методы получения и установки:
@Entity
@Table (name= "person")
public abstract class Person {
@Id @GeneratedValue
protected Long id;
protected String name;
protected String email;
protected String password;
@OneToOne
protected Address address;
Теперь класс Доктор.
@Entity(name = "doctor")
public class Doctor extends Person{
@OneToMany(mappedBy="doctor" , fetch = FetchType.EAGER, cascade = CascadeType.ALL)
@JsonManagedReference(value = "job-historical")
private List<MedicalConsultation> medicalConsultations;
@Enumerated
private Type type;
@ElementCollection
private List<String> specialties;
public Doctor() {
super();
}
public Doctor(String name, String email, String password, Address address,
List<String> specialties, Type type,
List<MedicalConsultation> medicalConsultations) {
super(name,email,password,address);
this.setMedicalConsultations(medicalConsultations);
this.setSpecialties(specialties);
this.setType(type);
}
Мои конструкторы вызывают super() и устанавливают свои значения в соответствии с суперклассом и его собственными свойствами.То же самое происходит с клиентским классом.
@Entity(name = "client")
public class Client extends Person{
@JsonManagedReference(value = "client-consultations-historical")
@OneToMany(mappedBy="doctor" , fetch = FetchType.EAGER, cascade = CascadeType.ALL)
private List<MedicalConsultation> medicalConsultations;
Здесь модель медицинской консультации, которая получает две другие модели
@Entity
@Table(name = "medical_consultation")
public class MedicalConsultation {
@Id
@GeneratedValue
private Long id;
@JsonBackReference(value = "job-historical")
@ManyToOne
@JoinColumn(name="doctor_fk")
private Doctor doctor;
@ManyToOne
@JoinColumn(name="client_fk")
@JsonBackReference( value = "client-consultations-historical")
private Client client;
@JsonFormat(pattern = "dd/MM/yyyy hh:mm")
private Date date;
private BigDecimal price;
Наконец, у нас возникла проблема: На моем контроллереЯ не могу получить полные данные медицинских консультаций.То есть я получил данные, удостоверение личности и цену, но я почему-то не получаю Клиента и Доктора.Но если я вызываю метод getDoctor() или getClient и возвращаю один из них, я вижу всю информацию.
См. Метод в классе RestControl:
@RestController
public class Control {
@Autowired
private PersonRepository personRepo;
@Autowired
private ClientRepository clientRepo;
@Autowired
private AddressRepository addressRepo;
@Autowired
private DoctorRepository doctorRepo;
@Autowired
private MedicalConsultationRepository consultationRepo;
@GetMapping("consultations")
public List<MedicalConsultation> getConsultations() {
List<MedicalConsultation> consultations = this.consultationRepo.findAll();
return consultations;
}
Может быть, что-то не так в картировании.Но я установил hibernate, чтобы показать sql, и он, очевидно, заставляет весь запрос получать все, что я хочу.См .:

Может кто-нибудь сказать мне, что происходит?
