GenericDao don't insert

[GoogleCodeExporter]

I have:

My DAO Interface:

{{{
public interface UserDao extends IDao<User, Long> {

    void persist(User user);

    User findByLogin(String login);

}
}}}


My DAO Implementation:

{{{
@Repository
@Transactional(readOnly = true)
public class UserDaoImpl extends GenericDao<User, Long> implements UserDao {

    public UserDaoImpl() {
    }

    @SuppressWarnings("unchecked")
    public User findByLogin(String login) {
        List<User> list = findByCriteria(Criteria.forClass(User.class).add(
                Restrictions.eq("login", login)));

        if (list == null || list.size() != 1) {
            return null;
        }

        return list.get(0);

    }
}

}}}

But when i need save in the controller with: userDao.save(user) nothings
happen in the database.


I have using Spring + Spirng MVC + JPA + Hibernate

I need help, thanks you.

I think that your problem is that UserDaoImpl must be a EJB. I don't know if 
Spring
can work with PersistenceContext.
In my case, i work with JBoss Application Server, and same code as you write 
works fine.

where is you void persist(User user) implementation ?

to in no place, because he thought he could use the Save method of the parent 
class:

userDao.save(user);

Really, i don't know.

I think that Spring should properly inject the persistence unit, regardless of 
the
container. But, as I use the JBoss application server simply can not tell you 
the
result of using Tomcat. 

I honestly do not know if I can help you much, since you are using a different
environment which I have running.

The fact is that you must continue to find out about the injection of the 
persistence
unit, poorly engineered design may be affecting the dependency injection.
