How to use Auditing in JPA/Spring-Data JPA?

问题

I am using JPA & Spring-Data JPA in a project. I have one table wherei Insert and then update the data. However i need the auditing information to save the state of all the objects i.e. I need state information of insert and all subsequent updates in another Table. I know I can use triggers in database to do this. However, Can this be done using JPA/Spring Data JPA?

Any help would be appreciated.

JPA spec (section 3.5) defines lifecycle callback methods:

prePersist
postPersist
preRemove
postRemove
preUpdate
postUpdate
postLoad

which are probably the closest thing you will find in pure JPA. SpringData itself has further auditing capabilities which are at a slightly higher level of abstraction. It describes these in section 2.4 of the reference manual.
