步骤二：实现我们自己的ActionListener接口

package com.laomao.view.listener;

import javax.el.ELContext;

import javax.el.MethodExpression;

import javax.faces.FacesException;

import javax.faces.application.Application;

import javax.faces.application.NavigationHandler;

import javax.faces.component.ActionSource2;

import javax.faces.context.FacesContext;

import javax.faces.el.EvaluationException;

import javax.faces.el.MethodBinding;

import javax.faces.event.AbortProcessingException;

import javax.faces.event.ActionEvent;

import javax.faces.event.ActionListener;

import org.apache.commons.logging.Log;

import org.apache.commons.logging.LogFactory;

?

public class ActionListenerImpl implements ActionListener {

??????

???????????????

??????????????????????????????

???????????????

????????????}

????????}

?

????????NavigationHandler navigationHandler = application.getNavigationHandler();

????????navigationHandler.handleNavigation(facesContext,fromAction,outcome);

????????//Render Response if needed

????????facesContext.renderResponse();

?

???????}

??????

???????/**

????????*?转入无权限声明页面

????????* @param expression

????????*/

???????private void gotoNoPermissionPage(MethodExpression expression) {

????????FacesContext context = FacesContext.getCurrentInstance();

????????Application application = context.getApplication();

???????????????

????????NavigationHandler navHandler = application.getNavigationHandler();

????????navHandler.handleNavigation(context, null == expression ? null : expression.getExpressionString(), Constants.NAVIGATION_NO_PERMISSION);

????????context.renderResponse();

????}

?

}
