I have a rather complicated DB structure that I am trying to audit. Currently I have Envers running and it audits the changes that are made to each object. This works really well!
I now want to show some audit information on the UI. The objects/tables get quite complicated so I was looking for a way to see what fields have changed in the audit. Currently Envers stores a snapshot of each object stamped with a revision id. I can look at each object’s revision and then manually query to see what has changed but I was wondering if there was a way I can get Envers to store which fields have changed. Is this possible? I found this link from 2011 and it recommends checking each object field manually. My concern here is speed. I have lots of objects related and I may only have one updated field. I will have to query a lot of fields to find the one that has changed.
Is it possible to store the fields that have changed?
Thanks
EDIT
I should have said that I am using the REVCHANGES table so I can see what has changed at what revisions but again this is only at entity level not field level
In newer Envers versions you can track which properties changed at each revision using a boolean flag. See:
