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

This is how I did it. You can try

    public class ABCService {
    @Resource(name="ABCDao")
    ABCDao abcDao;

    public int addNewABC(ABC abc) {
         ABC.setId(0);
         return abcDao.insertABC(abc);
    }
}
