Question

我有一个PhaseListener并且不起作用。但是在我的同事的计算机上如果有效的话。

我使用netbeans 6.8 With Glassfish 2.1和Windows 32位

PhaseListener：

package mx.udg.cgti.seguridad.listener;

import java.util.Enumeration;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.faces.application.NavigationHandler;
import javax.faces.context.FacesContext;
import javax.faces.event.PhaseListener;
import javax.faces.event.PhaseEvent;
import javax.faces.event.PhaseId;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import mx.udg.cgti.seguridadcore.negocio.ProcesosCNLocal;

public class SeguridadCorePhaseListener implements PhaseListener {

    public SeguridadCorePhaseListener() {
    }

    public void beforePhase(PhaseEvent pe) {
        System.out.println("beforePhase");
    }

    public void afterPhase(PhaseEvent pe) {
        System.out.println("afterPhase");
        if (pe.getPhaseId().equals(PhaseId.RESTORE_VIEW)) {

            if (pe.getFacesContext() != null) {

                String pagina = pe.getFacesContext().getViewRoot().getViewId();
                if (!"/Inicio.xhtml".equalsIgnoreCase(pagina) && !"/Login.xhtml".equalsIgnoreCase(pagina) && pagina.contains(".xhtml")) {
                    loggedIn();
                }
            }
        }
    }

    private void loggedIn() {
        String pagina = "";
        Long token = obtenToken();
        if (token != null) {
            String result = "";
            result = lookupProcesosCNLocal().getSesionActiva(token);
            if ("".equalsIgnoreCase(result)) {
                result = null;
            }
 //           System.out.println("RESULT " + result);
            if (result == null) {
                pagina = new String("sessionTimeout");
            }
        } else {
            pagina = new String("sinSession");
        }
 //       System.out.println(" PAGINA :- " + pagina + " TOKEN " + token);
        if (!pagina.equalsIgnoreCase("")) {
 //          System.out.println("REGLAS DE NAVEGACION TRABAJANDO HACIA  " + pagina);
            FacesContext fc = FacesContext.getCurrentInstance();
            NavigationHandler nh = fc.getApplication().getNavigationHandler();
            nh.handleNavigation(fc, null, pagina);
            fc.renderResponse();
        }

    }

    private Long obtenToken() {
        Long token = null;
        HttpServletRequest request = (HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
        HttpSession session = (HttpSession) FacesContext.getCurrentInstance().getExternalContext().getSession(false);
        Object t = request.getAttribute("token");
        if (t == null) {
            Object obj=null;
            if(session != null){
                obj = session.getAttribute("token");
                if(obj == null){
                    obj = request.getParameter("token");
                }
            }else{
                obj = request.getParameter("token");
            }
            if (obj != null) {
                if (obj != null && !"".equalsIgnoreCase(obj.toString())) {
                    token = Long.parseLong(obj.toString());
                }
            }
        } else {
            token = Long.parseLong(t.toString());
        }
        if (token != null) {
            request.setAttribute("token", token);
            if(session == null){
                session = (HttpSession) FacesContext.getCurrentInstance().getExternalContext().getSession(true);
            }
            session.setAttribute("token", token);
        }
        return token;
    }

    public PhaseId getPhaseId() {
        return PhaseId.RESTORE_VIEW;
    }

    private ProcesosCNLocal lookupProcesosCNLocal() {
        try {
            Context c = new InitialContext();
            return (ProcesosCNLocal) c.lookup("java:comp/env/ProcesosCN");
        } catch (NamingException ne) {
            Logger.getLogger(getClass().getName()).log(Level.SEVERE, "exception caught", ne);
            throw new RuntimeException(ne);
        }
    }

}

Answer 1

显然，你在类路径中的某个地方有另一个版本的同一个类，它在类加载到WAR中包含的类之前具有优先权。

可以位于服务器本身的/lib文件夹内，也可以位于服务器使用的已安装JRE的/lib或/lib/ext文件夹中。

我的phaseListener不起作用
