Hi All,
I'm using AppFuse 2.0 + Struts2 + Hibernate.
I need to timestamp all of my persisted data.
I have a base model class that includes a "lastUpdated" attribute and I
was hoping to be able to annotate it with something that would tell
Hibernate to timestamp it whenever it was saved to the DB, much as you
would do with an "After Update" trigger.
I've been hunting through the Hibernate documentation to see if it has
any "automatic" way of doing this, but haven't turned up anything
obvious. Hibernate has an @Temporal annotation, but AFAICT, it simply
provides a direction about the persisted datatype.
Is there any way to "automate" this or will I have to do it myself in
the DAO? If I have to do it myself in the DAO, I assume the most
efficient way will be to have a base DAO class that sits between
GenericDao and my own Dao's and have it do the timestamping.
TIA,
