I have a 3 layer application using spring and hibernate (controller -> service -> dao) and transaction is applied to service layer. I don't configure OpenSessionInViewInterceptor or OpenSessionInViewFilter and I want to know the hibernate session control behavior. Open session per transaction or per request? Thanks!

A:
If you're using the HibernateTransactionManager, a Session will get bound to the current thread and flushed and closed when the transaction ends, either through commit or roll back.

@stinghu Yes, one Session per transaction/thread.

Thanks, Pascal! Another question, if one controller calls two different service method (they are in different transactions but in only one thread), there should be two sessions opened. Am I right?

@stinghu Yes, that's right.

@stinghu provided that the controller method is not marked `@Transactional` itself, that is.
