How to add items to a list with Spring JPA Onetomany with Postman

Question

I searched several places and did not find an answer, because it just doesn’t work by putting the annotations @Onetomany and @Manytoone, already put with fetch, with Mapped, didn’t work.

1 - How JPA relates two classes?

@Entity
public class Usuario {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name ="id")
    private Long codigoUsuario;

    private String nome;

    @Column(unique = true)
    @NotNull
    private String cpf;

    @NotNull
    private String dataNascimento;

    //@JoinColumn(name="id")
    //@Transient
    @OneToMany(mappedBy = "usuario")
    private List<Endereco> list;

    public List<Endereco> getList() {
        return list;
    }


@Entity
public class Endereco {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name ="endereco_id")
    private Long id;       

    private String logradouro;

    @NotNull
    private String bairro;

    @NotNull
    private String cidade;

    @NotNull
    private String estado;

    @NotNull
    private String cep;

   @ManyToOne
   @JoinColumn(name = "codigoUsuario")
   private Usuario usuario;

    public Usuario getUsuario() {
        return usuario;
    }

2 - It is mandatory to create a query to relate the address list to the user class?

3 - As I update the address list, with a specific user, this is correct, if I go through POSTMAN?

{
    "nome":"Rosana da Silva",
    "email":"[email protected]",
    "cpf":"5557059",
    "dataNascimento": "14-12-1998",
    "endereco":[{"id":611}]
}

@PostMapping("/usuario")
    @ResponseStatus(value = HttpStatus.CREATED, reason = "Usuário cadastrado")
    public Usuario salvaUsuario(@RequestBody Usuario usuario){

       
        try {
            return usuarioService.salvaUsuario(usuario);
        } catch (Exception e){
            throw new UsuarioInvalidoException("Cadastro inválido");
        }
    }
