I have a web application with JSF + Spring but when I reference an Autowired object got an NullPointerException error.

My interface:
public interface PerfilService {
public List<Perfil> buscar();
public Perfil buscarXID(Integer id);
}
My Impl:
@Service("perfilService")
@Qualifier("impl1")
public class PerfilServiceImpl implements PerfilService {
@Override
public List<Perfil> buscar() {
return null;
}
@Override
public Perfil buscarXID(Integer id) {
return null;
}
}
My Bean:
@Component
@ManagedBean(name = "listados")
@ApplicationScoped
public class ListadoBean {
@Autowired
@Qualifier("impl1")
PerfilService perfilService;
public List<Perfil> getPerfiles() {
perfiles = perfilService.buscar();
return perfiles;
}
}
Error is produced when I call perfiles = perfilService.buscar(); because perfilService is null
