Problems with #Autowired, with a ManagedBean and an abstract class - spring

Question

Well, I have an abstract class like this:
public abstract class BasicCrudMBImpl<Bean, BO> extends BasicMBImpl {
protected Bean bean;
protected List<Bean> beans;
protected BO boPadrao;
public void deletar() {
try {
((BasicBO) boPadrao).delete((AbstractBean) bean);
addInfoMessage("Registro deletado com sucesso");
beans = retornaBeansDoBanco();
bean = null;
} catch (BOException e) {
addErrorMessage(e.getMessage());
}
}
public void salvar(ActionEvent event) {
try {
if (((AbstractBean) bean).getId() == null) {
bean = (Bean) ((BasicBO) boPadrao).save((AbstractBean) bean);
addInfoMessage("Registro salvo com sucesso");
} else {
((BasicBO) boPadrao).update((AbstractBean) bean);
addInfoMessage("Registro atualizado com sucesso");
}
beans = retornaBeansDoBanco();
} catch (BOException e) {
FacesContext.getCurrentInstance().validationFailed();
addErrorMessage(e.getMessage());
}
}
public Bean getBean() {
return bean;
}
public void setBean(Bean bean) {
this.bean = bean;
}
public List<Bean> getBeans() {
try {
if (beans == null)
beans = (List<Bean>) retornaBeansDoBanco();
return beans;
} catch (BOException e) {
addErrorMessage(e.getMessage());
}
return null;
}
public void setBeans(List<Bean> beans) {
this.beans = beans;
}
// Deve ser implementado para carregar a query adequada ao bean necessário
public abstract List<Bean> retornaBeansDoBanco();
public abstract void novo(ActionEvent event);
public abstract void alterar(ActionEvent event);
public BO getBoPadrao() {
return boPadrao;
}
public abstract void setBoPadrao(BO boPadrao);
public void addErrorMessage(String componentId, String errorMessage) {
addMessage(componentId, errorMessage, FacesMessage.SEVERITY_ERROR);
}
public void addErrorMessage(String errorMessage) {
addErrorMessage(null, errorMessage);
}
public void addInfoMessage(String componentId, String infoMessage) {
addMessage(componentId, infoMessage, FacesMessage.SEVERITY_INFO);
}
public void addInfoMessage(String infoMessage) {
addInfoMessage(null, infoMessage);
}
private void addMessage(String componentId, String errorMessage,
FacesMessage.Severity severity) {
FacesMessage message = new FacesMessage(errorMessage);
message.setSeverity(severity);
FacesContext.getCurrentInstance().addMessage(componentId, message);
}
}
In ManagedBean I tried to inject the "boPadrao" with #Autowired, like this:
#ManagedBean(name = "enderecoMB")
#ViewScoped
public class EnderecoMBImpl extends BasicCrudMBImpl<Endereco, BasicBO> {
private static Logger logger = Logger.getLogger(EnderecoMBImpl.class);
private List<TipoEndereco> tiposEndereco;
private List<Logradouro> logradouros;
#PostConstruct
public void init() {
logger.debug("Inicializando componentes no PostConstruct");
beans = retornaBeansDoBanco();
tiposEndereco = (List<TipoEndereco>) boPadrao
.findByNamedQuery(TipoEndereco.FIND_ALL);
logradouros = (List<Logradouro>) boPadrao
.findByNamedQuery(Logradouro.FIND_ALL_COMPLETO);
}
#Override
public List<Endereco> retornaBeansDoBanco() {
return (List<Endereco>) getBoPadrao().findByNamedQuery(Endereco.FIND_ALL_COMPLETO);
}
#Override
public void novo(ActionEvent event) {
bean = new Endereco();
}
#Override
public void alterar(ActionEvent event) {
// TODO Auto-generated method stub
}
public List<TipoEndereco> getTiposEndereco() {
return tiposEndereco;
}
public void setTiposEndereco(List<TipoEndereco> tiposEndereco) {
this.tiposEndereco = tiposEndereco;
}
public List<Logradouro> getLogradouros() {
return logradouros;
}
public void setLogradouros(List<Logradouro> logradouros) {
this.logradouros = logradouros;
}
#Autowired
public void setBoPadrao(BasicBO boPadrao) {
this.boPadrao = boPadrao;
}
}
But this doesn't works, the boPadrao is always null, getting a "NullPointerException". The error occurs in method retornaBeansDoBanco();
