We want that whenever row inserted by hibernate, it should use the sequence present in database (which was created by our-self) and NOT default hibernate generated 'hibernate_sequence' Follow these simple steps to link your database sequence with hibernate (Using Sequence generation strategy) 1.Create sequence in the database. 2.Create java class with with jpa/hibernate annotations You can insert the row in database table directly or through hibernate, this sequence will work without any gaps.
