Spring managed transactions without @Transactional annotation

Question

I\'m using Spring annotations to manage my transactions like so:

@Transactional(readOnly = true)
public class AlertServiceImpl implements AlertService {

            


        

Answer 1

In your scenario your DAO will execute without transaction, most probably with auto-commit.

If you want to avoid this kind of mistake in future and require all your services to run in transaction you can protect DAO layer with following @Transactional annotation:

@Transactional(propagation = MANDATORY)
public class HibernateAlertDAO extends HibernateDaoSupport implements AlertDAO {
   ...
}

This annotation will require service layer to declare transaction and will throw exception otherwise.
