I had this same problem. I have solved this by creating: applicationContext.xml

    




    
    
    
    


    
    
    
        
            ${mySql.dialect}
        
    
    
        classpath:hibernate.cfg.xml
    



    





    
    
    
    


    
    
    
        
            ${oracle.dialect}
        
    
    
        classpath:hibernate.cfg.xml
    



    

in Dao injected sessionFactory with Qualifier annotation. In my case I had generic BaseEnity:

public abstract class BaseEntityDAOImpl implements BaseEntityDAO {

private Class persistentClass;
@Autowired
@Qualifier("oracleSessionFactory")
SessionFactory sessionFactory;
}

and in service bean using annotation:

@Service
@Transactional(propagation = Propagation.REQUIRED, readOnly = true, value = "oracleTransactionManager")
public class UserService {

@Autowired
private UserDAO dao;
}

Averythings wokrs fine.
