I already asked this question previously but now it gives me another error product of a change. I am a beginner in this Spring-Hibernate (I know the essentials). I have created in Netbean a login with hibernate (annotations) and access to MySql but when I added Spring and its annotations I got stuck, already in the first attempt I did not achieve it. By order I have created the packages classes, bean, bo, bo.Spring, dao, dao.Spring with the following code as it corresponds:
This is the code of the JSF page

This is the code of the Bean User
package beans;
import clases.UsuarioLogin;
import bo.spring.IUsuarioBo;
import java.io.Serializable;
import java.util.List;
import javax.faces.application.FacesMessage;
import javax.faces.component.html.HtmlDataTable;
import org.springframework.stereotype.Component;'
@Component //Cambio de ManagedBean y eliminacion de Sessionscoped por Component
public class UsuarioBean implements Serializable{
private UsuarioLogin elUsuario;
private IUsuarioBo usuarioBo;
private boolean agregado;
private FacesMessage msj;
private List<UsuarioLogin> listaUsuario;
private HtmlDataTable tableUsuario;'
public UsuarioBean (){
elUsuario = new UsuarioLogin();
// usuarioBo = new UsuarioBo(); // Solo para pruebas y simulaciones
}
public String entrar(UsuarioLogin elUsuario){
boolean existe;
existe = usuarioBo.entrar(elUsuario);
if (existe) {
return "index.xhtml";
} else{
return "";
}
}
In the bo package
package bo;
import clases.UsuarioLogin;
import bo.spring.IUsuarioBo;
import dao.spring.IUsuarioDao;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service
public class UsuarioBo implements IUsuarioBo {
@Autowired
private IUsuarioDao usuarioDao;
@Override
public boolean entrar(UsuarioLogin elUsuario) {
return usuarioDao.entrar(elUsuario);
}
public void setUsuarioDao(IUsuarioDao usuarioDao) {
this.usuarioDao = usuarioDao;
}
}
The error that occurs to me is the following
Caused by: javax.el.PropertyNotFoundException: /access.xhtml @ 19,69 value="# {userBean.username}": Target Unreachable, identifier 'userBean' resolved to null
Any help you can give me, I thank you from now on.
