Answer 1

There are no transactions in your sample project. Add:

And annotate your DAO with @Transactional:

@Transactional
@Repository 
public class UserDaoImpl implements UserDao

Two notes:

• you are correctly marking your DAO with @Repository, but it only handles exception translation:

  A class thus annotated is eligible for Spring DataAccessException translation

• consider placing @Transactional on higher level classes (@Services), see What is the right way to use spring MVC with Hibernate in DAO, sevice layer architecture for discussion
