dependency injection using concrete classes

[Sonx Nkuks]

Hi, i have followed the hibernate Factory implementation which uses abstractDAO for all my DAOs. I now need to inject my DAOs which extends this Abstract to Spring service layer (Manager class). Here's an example

@Autowired
BasketDAO basketDao;

@Transactional(readOnly = true)		
public List<Basket> getAllBaskets() {
	return basketDao.findAll();
}

@Transactional(readOnly = true)	
public Basket getBasket(String basketReference) {
	return basketDao.findBasketByReference(basketReference);
}

@Transactional(readOnly = true)	
public Basket getBasketById(Integer entityId) {
	return basketDao.findById(entityId);
}

@Transactional	
public void save(Basket Basket) {
	basketDao.save(Basket);
}

@Transactional
public void delete(Basket Basket) {
	basketDao.delete(Basket);
}

@Transactional	
public void update(Basket basket) {
	basketDao.update(basket);
}

Problem is basketDao is an interface, and all these crud methods (except findBasketByReference() which is unique to DAO) are abstract/generic therefore not implemented on any of my DAOs but on AbstractDAOImpl. So they aren't visible to the interface BasketDAO which is injected to the service. Can i inject rather BasketDAOImpl as it will access these methods
