NullPointerException in Spring Autowiring Repository - spring

Question

I'm getting an NPE when I'm trying to auto wiring a Repository in my managed bean. This is my first project trying to use java configurations instead of xml configurations.
I'm not instantiating my self the repository and all the packages are in the spring context, even I can see in the log the instantiating of the repository.
Please, someone, give me a hand to figure out what's missing in my configuration
Using spring version 5.1.0.RELEASE and
<dependency>
<groupId>com.googlecode.genericdao</groupId>
<artifactId>dao-hibernate</artifactId>
<version>1.2.0</version>
</dependency>

resolver.setViewClass(JstlView.class);

#ManagedBean
#Scope("view")
#Component
public class AdminEdificios extends FindCrudBeanBase {
#Autowired
ApplicationContext applicationContext;
#Autowired
PaisRepository paisRepository;
private static final Logger LOG = LoggerFactory.getLogger(AdminEdificios.class);
private List<PaisDTO> listaPaises;
private List<DepartamentoDTO> listaDepartamentos;
private List<ProvinciaDTO> listaDistritos;
private List<DistritoDTO> listaProvincias;
private String codigoPaisSeleccionado;
private String codigoDepartamentoSeleccionado;
private String codigoProvinciaSeleccionada;
private String codigoDistritoSeleccionado;
#PostConstruct
public void init() {
listaPaises = paisRepository.findAll();
listaDepartamentos = new ArrayList<DepartamentoDTO>();
listaDepartamentos.add(new DepartamentoDTO("001","001","Lima"));
}
...
getters & setters
}
The NPE is exactly here
listaPaises = paisRepository.findAll();
