@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

Hibernate fails in silent and mysterious ways when the ID column is an Int. Try changing it to Long in the code and an unsigned 64-bit integer in the database. That fixed the issue for me.
