Question

I have a model class that is mapped to a postgres database using hibernate. My model class is:

@Entity
@Table(name=\"USER\")
public class User {

    @Id 
    @G         


        

Answer 1

Use: @GeneratedValue(strategy = GenerationType.IDENTITY)

In your POJO class Id Field. This thing solved my error.
