JPA - Returning an auto generated id after persist()

Question

I\'m using JPA (EclipseLink) and Spring. Say I have a simple entity with an auto-generated ID:

@Entity
public class ABC implements Serializable {
     @Id
           


        

Answer 1

@Entity
public class ABC implements Serializable {
     @Id
     @GeneratedValue(strategy=GenerationType.IDENTITY)
     private int id;   
}

check that @GeneratedValue notation is there in your entity class.This tells JPA about your entity property auto-generated behavior
