Use the IDENTITY generation type instead of auto. Use a Long for id. I also recommend changing the name from UserID to userId. Do not forget the @Entity for the class name.

@Entity
public class MyClass{

private Long userId;

    @Id 
    @GeneratedValue(strategy=GenerationType.IDENTITY) 
    @Column
    public Long getUserID(){
        return userId;
    }

    //.. rest of class

}

Be very careful with the naming conventions and make sure your field names and types match the field names and types from the database.

Use

@GenericGenerator(name="generator", strategy="increment")
@GeneratedValue(generator="generator")
