@GeneratedValue(strategy = GenerationType.AUTO) not working as thought

Question

I\'m trying to persist an object to a database. Keep getting \'Column ID cannot accept null value error\'. My object looks like this:

    @Entity
public cl         


        

Answer 1

You may use GenerationType.TABLE. That way, jpa uses a sequence table for id assigment and you may never need to generate sequence or auto-increment values or triggers that lowers portability.

Also note that in java int type is initiated with 0 default, so you may get rid of that also.
