Ele não esta conseguindo injetar o categoriaService, como está sua classe CategoriaService ? Tem anotação de @Service nela ?

Minha classe service estava sem "@Service" e coloquei a anotação e mesmo assim o problema persiste.
Obrigado
Obrigado
@Service
public class CategoriaServiceImpl implements CategoriaService {
@Autowired
private CategoriaDAO categoriaDAO;
@Override
public List<Categoria> listCategoria() {
return categoriaDAO.listCategoria();
}
}

Certo, lembre-se que todas as injeções do spring devem ser anotadas.
