Can I stop auto persistence for a particular class? There are a few attributes of a class that are converted before persisting to the table. The attributes are converted back after session.find(). These returned objects with the converted attributes are considered dirty by Hibernate, and are persisted automatically during the session. The problem is that the persisted objects now end up with unconverted attributes in the table.

Is there a way to stop to specify read-only for session.find() if I can stop auto persistence?

Thanks,

What is mutable in the class definiton for? Will it help my situation? Do I need a custom persister? Thare are two session.find() calls in the code for the same class/table in a single session, and the auto update happens in the 2nd session.find(). I am clonning the return objects from session.find() to avoid the auto updates, but hope there's a more elegant solution.

1. map a private getter and add a public getter doing your data transfo.

2. Non mutable classes cannot be updated at all (only saved and retrieved)
3. Have a look at update and insert attributes in property tag.

3. Interceptors might help
