How to generate id's in sequence - Play Framework 2.3.4

Question

I have this class:

@Entity
public class Sale extends Model {

    // ...

    @Id
    @GeneratedValue
    private Long number;

    // ...

}

When I call save on the first sale, its number becomes 1, but when I call save on the second sale, its number becomes 33. How can I make the @Id numbers be generated in a sequence (1, 2, 3, 4, ...)?

Answer 1

I just use it like this:

@Id private Long id;

and it generates in in sequence I tried it in both MYSql and SQLite.
