我永远得到同样的例外。
我有4个Named Beans，其中一个是存储用户会话的SessionScoped Bean。使用@Inject将此bean注入另一个bean。我使用的是JSF 2.2。
这是代码：
package vista;
import modelo.Contacto;
import modelo.Usuario;
import negocio.Negocio;
import javax.faces.bean.SessionScoped;
import javax.faces.context.FacesContext;
import javax.inject.Inject;
import javax.inject.Named;
import java.io.Serializable;
import java.util.List;
@Named
@SessionScoped
public class InfoSesion implements Serializable{
@Inject
private Negocio negocio;
private Usuario usuario;
/**
* Creates a new instance of InfoSesion
*/
public InfoSesion() {
}
public synchronized void setUsuario(Usuario usuario) {
this.usuario = usuario;
}
public synchronized Usuario getUsuario() {
return usuario;
}
public synchronized List<Contacto> getContactos()
{
if (usuario != null)
{
return usuario.getContactos();
}
return null;
}
public synchronized String invalidarSesion()
{
if (usuario != null)
{
usuario = null;
FacesContext.getCurrentInstance().getExternalContext().invalidateSession();
}
return "login.xhtml";
}
public synchronized void refrescarUsuario()
{
if (usuario != null)
{
usuario = negocio.refrescarUsuario(usuario);
System.out.println(usuario.getContactos().size());
}
}
}
在此视图中，我使用infoSesion：
