Issue
I am trying to implement an api to book an appointment.
i have two entity class and one transaction class.
@Entity
@Table(name="user")
public class User implements Serializable {
@Column(name = "user_id")
private @Id @GeneratedValue int userid;
private @NotBlank String username;
private @NotBlank String password;
private @NotBlank String first_name;
private @NotBlank String Last_name;
private @NotBlank String disease;
}
Doctor class
@Entity
@Table(name = "doctors")
public class Doctor implements Serializable {
@Column(name = "doctor_id")
private @Id @GeneratedValue(strategy = GenerationType.IDENTITY) int doctorid;
private @NotBlank String doctor_name;
private @NotBlank String speciality;
Appointment class
@Entity
@Table(name = "appointments")
public class Appointment implements Serializable {
@Id
@GeneratedValue
private @NotBlank int App_id;
private @NotBlank String date;
private @NotBlank String time;
@OneToOne
@JoinColumn(name = "user_id")
private User user_id;
@OneToOne
@JoinColumn(name = "doctor_id")
private Doctor doctor_id;
public Appointment(){}
public Appointment( String date, String time,User usr,Doctor doc) {
this.date = date;
this.time = time;
this.user_id = usr;
this.doctor_id = doc;
}
Service class
` public Status bookappointment(Appointment appointment){
appointmentRepository.save(appointment);
return Status.SUCCESS; }`
Controller class
@PostMapping("/BookAppointment")
public Status book(@RequestBody Appointment ap){
System.out.println(ap.toString());
return appointmentService.bookappointment(ap);
}
In postman I am trying to send the post request
{
"date":"12/12/2021",
"time":"4:05",
"doctor_id": 4,
"user_id":14
}
But I am getting this error

What is the problem i am not able to understand?
