Answer 1

I found the solution. As Javi said (thanks a lot for you, Javi), I have to annotate DAO and Service layer classes with @Repository and @Service annotation. Now I've tried to write like this:

@Service("someService")
public class SomeServiceImpl implements SomeService{    
    @Autowired
    @Qualifier("myDAO")
    private MyDAO myDAO;

    ....
}

and

@Repository("myDAO")
    public class JDBCDAOImpl implements MyDAO {    
    @Autowired
    @Qualifier("dataSource")
    private DataSource dataSource;    
    ....
}

and all works fine!!!

But I still not found an answer for this quesion: if application will be more complex, and will have more complex structure, where @Repositore and @Service annotation are not preferred for some classes, how to inject correctly beans, which located in lower levels (in a fields of classes, or in a field of fields of classes) (with @Autowire annotation, of course)?
