hibernate event detecter

Question

I have a DB running on Oracle. I use Hibernate for data access. I want to be notified whenever an object is saved in the DB, so that I can do some custom work. I want an "event listener" if you could call it that. Is there a way to detect such task ?

Answer 1

On Hibernate level, this is done using interceptors

On Oracle level, it's called trigger:

create or replace trigger <triggername>
before/after insert or update or delete
on <tablename> 
for each row/for each statement
