Java 如何制作Restful API来处理Spring引导中的多对多关系？

在我的Spring boot项目中，我有两个表名-医生和患者。在这些表中，我有以下属性-

现在，我想在这两个表之间为预约创建一个多对多关系，因为一个医生可以有多个病人，一个病人可以预约多个医生。因此，为了处理这个问题，我创建了另一个名为appointment的表，它将把doctorId和patientId作为外键

我需要使用JSON请求体创建约会，如下所示-

为此，我创建了一个模型类，如下所示-

Appointment.java

@Entity
@Table(name = "appointments")
public class Appointment {

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

    @NotNull
    private Long appointedDoctorId;

    @NotNull
    private Long appointedPatientId;

    @ManyToOne(fetch = FetchType.LAZY, optional = false)
    @JoinColumn(name = "doctorId", nullable = false)
    private Doctor doctor;


    @ManyToOne(fetch = FetchType.LAZY, optional = false)
    @JoinColumn(name = "patientId", nullable = false)
    private Patient patient;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }


    public Long getAppointedDoctorId() {
        return appointedDoctorId;
    }

    public void setAppointedDoctorId(Long appointedDoctorId) {
        this.appointedDoctorId = appointedDoctorId;
    }

    public Long getAppointedPatientId() {
        return appointedPatientId;
    }

    public void setAppointedPatientId(Long appointedPatientId) {
        this.appointedPatientId = appointedPatientId;
    }

    public Doctor getDoctor() {
        return doctor;
    }

    public void setDoctor(Doctor doctor) {
        this.doctor = doctor;
    }

    public Patient getPatient() {
        return patient;
    }

    public void setPatient(Patient patient) {
        this.patient = patient;
    }
}

@Repository
public interface AppointmentRepository extends JpaRepository<Appointment, Long> {

    Page<Appointment> findByDoctorId(Long id, Pageable pageable);

}

public interface AppointmentService {

    public Page<Appointment> getAllAppointmentByDoctorId(@PathVariable(value = "doctorId") Long id, Pageable pageable);

    public Appointment createAppointment(@Valid @RequestBody Appointment createAppointmentRequest);

}

@Service
public class AppointmentServiceImpl implements AppointmentService {

    @Autowired
    AppointmentRepository appointmentRepository;


    @Override
    public Page<Appointment> getAllAppointmentByDoctorId(Long id, Pageable pageable) {
        return appointmentRepository.findByDoctorId(id, pageable);
    }

    @Override
    public Appointment createAppointment(@Valid Appointment createAppointmentRequest) {
        return appointmentRepository.save(createAppointmentRequest);
    }
}

@RestController
@RequestMapping("/api")
public class AppointmentController {

    @Autowired
    AppointmentService appointmentService;

    @GetMapping("/doctors/{doctorId}/appointments")
    public Page<Appointment> getAllAppointmentsByDoctorId(@PathVariable(value = "id") Long id, Pageable pageable){
        return appointmentService.getAllAppointmentByDoctorId(id, pageable);
    }


    @PostMapping("/insert/new/appointments")
    public Appointment createAppointment(@Valid Appointment createAppointmentRequest) {
        return appointmentService.createAppointment(createAppointmentRequest);
    }

}

这是存储库类-

AppointRepository.java

@Entity
@Table(name = "appointments")
public class Appointment {

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

    @NotNull
    private Long appointedDoctorId;

    @NotNull
    private Long appointedPatientId;

    @ManyToOne(fetch = FetchType.LAZY, optional = false)
    @JoinColumn(name = "doctorId", nullable = false)
    private Doctor doctor;


    @ManyToOne(fetch = FetchType.LAZY, optional = false)
    @JoinColumn(name = "patientId", nullable = false)
    private Patient patient;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }


    public Long getAppointedDoctorId() {
        return appointedDoctorId;
    }

    public void setAppointedDoctorId(Long appointedDoctorId) {
        this.appointedDoctorId = appointedDoctorId;
    }

    public Long getAppointedPatientId() {
        return appointedPatientId;
    }

    public void setAppointedPatientId(Long appointedPatientId) {
        this.appointedPatientId = appointedPatientId;
    }

    public Doctor getDoctor() {
        return doctor;
    }

    public void setDoctor(Doctor doctor) {
        this.doctor = doctor;
    }

    public Patient getPatient() {
        return patient;
    }

    public void setPatient(Patient patient) {
        this.patient = patient;
    }
}

@Repository
public interface AppointmentRepository extends JpaRepository<Appointment, Long> {

    Page<Appointment> findByDoctorId(Long id, Pageable pageable);

}

public interface AppointmentService {

    public Page<Appointment> getAllAppointmentByDoctorId(@PathVariable(value = "doctorId") Long id, Pageable pageable);

    public Appointment createAppointment(@Valid @RequestBody Appointment createAppointmentRequest);

}

@Service
public class AppointmentServiceImpl implements AppointmentService {

    @Autowired
    AppointmentRepository appointmentRepository;


    @Override
    public Page<Appointment> getAllAppointmentByDoctorId(Long id, Pageable pageable) {
        return appointmentRepository.findByDoctorId(id, pageable);
    }

    @Override
    public Appointment createAppointment(@Valid Appointment createAppointmentRequest) {
        return appointmentRepository.save(createAppointmentRequest);
    }
}

@RestController
@RequestMapping("/api")
public class AppointmentController {

    @Autowired
    AppointmentService appointmentService;

    @GetMapping("/doctors/{doctorId}/appointments")
    public Page<Appointment> getAllAppointmentsByDoctorId(@PathVariable(value = "id") Long id, Pageable pageable){
        return appointmentService.getAllAppointmentByDoctorId(id, pageable);
    }


    @PostMapping("/insert/new/appointments")
    public Appointment createAppointment(@Valid Appointment createAppointmentRequest) {
        return appointmentService.createAppointment(createAppointmentRequest);
    }

}

@存储库
公共接口任命存储库扩展了JpaRepository

所以，我需要知道我的代码中有什么问题，以及如何通过像我在JSON RequestBody请求中提到的那样提供doctorId和patientId来创建预约POST request。
看起来你已经回答了这个问题。你能检查一下你的列名是什么吗预约表中的
医生id
或
医生id
？问题已更新，请检查。
