How to insert an object inside another in Spring - spring

Question

I'm trying to insert the Insurance object into **User **through an endpoint in Spring, but either the request asks me for all User attributes or the object is not inserted.
**User Class **
#Entity
#Table(name = "users",
uniqueConstraints = {
#UniqueConstraint(columnNames = "username"),
#UniqueConstraint(columnNames = "email")
})
#AllArgsConstructor
#NoArgsConstructor
#Data
public class User {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
#NotBlank
#Size(max = 20)
private String username;
private String documento;
private String telefone;
#Value("${some.key:false}")
private boolean first_acess;
private String formacao;
private String sexo;
private String data_nascimento;
#NotBlank
#Size(max = 50)
#Email
private String email;
#NotBlank
#Size(max = 120)
private String password;
#ManyToMany(fetch = FetchType.LAZY)
#JoinTable( name = "user_roles",
joinColumns = #JoinColumn(name = "user_id"),
inverseJoinColumns = #JoinColumn(name = "role_id"))
private Set<Role> roles = new HashSet<>();
#Embedded
private Address address;
#ManyToOne
#JoinColumn(name = "insuranceId")
private Insurance insurance;
Insurance class
#Data
#Entity
#AllArgsConstructor
#NoArgsConstructor
#Table(name = "insurance")
public class Insurance {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long insuranceId;
private String name;
private String valor;
private String maximoDependentes;
private String vencimento;
private String descricao;
}
Request to insert into class
#PostMapping("/User/{id}/addPlan")
public ResponseEntity<User> addPlanToUser(#PathVariable("id") long id, #RequestBody SignInsuranceRequest signInsuranceRequest) {
User user = userRepository.findById(id)
.orElseThrow(() -> new ResourceNotFoundException("Not found User with id = " + id));
return new ResponseEntity<>(userRepository.save(user), HttpStatus.OK);
}
Custom request for the solution
public class SignInsuranceRequest {
#ManyToOne
#JoinColumn(name = "insuranceId", insertable = false, updatable = false)
private Insurance insurance;
public Insurance getInsurance() {
return insurance;
}
public void setInsurance(Insurance insurance) {
this.insurance = insurance;
}
}
I already tried to put the User in #RequestBody and just ask for the insurance and it didn't work either
Example of how it was done
#PutMapping("/User/{id}/addPlan")
public ResponseEntity<User> addPlanToUser(#PathVariable("id") long id, #RequestBody User user) {
User _user = userRepository.findById(id)
.orElseThrow(() -> new ResourceNotFoundException("Not found User with id = " + id));
_user.setInsurance(user.getInsurance());
return new ResponseEntity<>(userRepository.save(_user), HttpStatus.OK);
}
In this attempt, I would pass the id of an insurance in the body of the request and the ID of the user in the Header but the id of the database was not retrieved.
Response
{
"id": 1,
"username": "user",
"documento": null,
"telefone": null,
"first_acess": false,
"formacao": null,
"sexo": null,
"data_nascimento": null,
"email": "user#user.com",
"password": "$2a$10$DUkVRxFFiR7L2OpwwpxHyOCC.7v/iFLqp66BBqy3AC0lHrVa9lnQK",
"roles": [],
"address": null,
"insurance": {
"insuranceId": 1,
"name": "string",
"valor": "string",
"maximoDependentes": "string",
"vencimento": "string",
"descricao": "string"
}
}
I expected to insert an User class into a Insurance Class(Already created) and return the object of User completed.
