Добрый день. Имею следующую проблему:
org.hibernate.id.IdentifierGenerationException: null id generated for:class Notebook.Enities.Telephone
Суть понятна, дебаг подтверждает: в id у нас null у telephone.
GitHub:
NotebookСУБД MySQL.
Поле Id: Id int(11) not null;
Класс Note.java
@Component
public class Note {
private int id;
private Description descriptionId;

private Group group;
public Note (){

public Note(int id, Description descriptionId, Human humanId, Telephone telephoneId, Group group) {
this.id = id;
this.descriptionId = descriptionId;
this.humanId = humanId;
this.telephoneId = telephoneId;
this.group = group;
