I have a small method that looks like this:

Account account = (Account)accountDAO.findByUserID(userID);
account.depositAmount(amount);
accountDAO.store(account);

The .store() method may sometimes throw MyIOException (when database access fails), and in these cases I would like to rollback this whole code snippet ie I would like to undo my call to the depositAmount() method. Can I do this somehow using Hibernate and/or Spring?

If this is not doable, is it safe to clone the account object, call the depositAmount() on the cloned object and then try to save that? In this case if the .store() method fails, I could just throw-away the reference to the cloned object and it would be garabage collected, no?


Sincerly,

Hibernate has full support for transactions so if the operation in question is wrapped in a transaction (as it should be) then the answer is yes. Cloning the POJO can be OK - I would return the clone on error rather than update it as it will be obvious what your doing when reading the code.
