How to check if object is dirty

I understand that hibernate performs automatic dirty checking on the domain object before persisting it.

I have a requirement to log the event every time a record is modified. Is there any API that I can use to check if an object is dirty?

There are a few things you can do.

You can use interceptors.

or Event listeners

or the @PreUpdate callback from Entity Listeners (This is JPA compliant).

For me, personally, Entity listeners seems to be the cleanest.
