我用容器管理的安全性编写了简单的应用程序.问题是当我登录并打开另一个我注销的页面时,然后我回到第一页,我点击任何链接等或刷新页面我得到这个例外.我想这是正常的(或者可能不是:))因为我退出了会话被破坏了.我该怎么做才能将用户重定向到例如index.xhtml或login.xhtml,并使他免于看到错误页面/消息？

换句话说,如何在我退出后自动将其他页面重定向到索引/登录页面？

这里是:

请考虑以下情形.在会话超时(过期)后,我点击了JSF表单的提交按钮.浏览器显示一些异常消息:

ViewExpiredException:无法恢复视图上下文

我想要做的是,在会话过期后自动重定向到网站的主页.这样做的机制是什么？任何帮助将非常感激.

ExceptionHandlerFactory到目前为止,我遇到的所有示例都将用户重定向到一个viewExpired.jsf页面,以防ViewExpiredException被捕获:

public class ViewExpiredExceptionExceptionHandler extends ExceptionHandlerWrapper {
    private ExceptionHandler wrapped;

    public ViewExpiredExceptionExceptionHandler(ExceptionHandler wrapped) {
        this.wrapped = wrapped;
    }

    @Override
    public ExceptionHandler getWrapped() {
        return this.wrapped;
    }

    @Override
    public void handle() throws FacesException {
        for (Iterator<ExceptionQueuedEvent> i = getUnhandledExceptionQueuedEvents().iterator(); i.hasNext();) {
            ExceptionQueuedEvent event = i.next();
            ExceptionQueuedEventContext context = (ExceptionQueuedEventContext) event.getSource();

            Throwable t = context.getException();
            if (t instanceof ViewExpiredException) {
                ViewExpiredException vee = (ViewExpiredException) t;
                FacesContext facesContext = FacesContext.getCurrentInstance();
                Map<String, Object> requestMap = facesContext.getExternalContext().getRequestMap();
                NavigationHandler navigationHandler = …

我已经设置了web.xml,以便任何java.lang.Throwable(即任何未捕获的异常或错误)将转发到错误页面.但是,对于AJAXified组件,异常不会通过此机制路由到错误页面.

我所拥有的测试用例是一个简单CommandButton的操作方法,它总是抛出一个RuntimeException.看起来最好的做法是让action方法捕获异常并添加FacesMessage类型错误严重性.这是人们做的吗？有没有办法配置JSF,以便如果AJAXified组件的支持bean方法抛出异常,可以显示错误页面？

我希望显示<p:growl>会话已过期.我找到了许多处理会话过期的方法,如会话超时和JSF/PrimeFaces ajax请求上的ViewExpiredException处理,但是我无法将faces消息推送到<p:growl>.

到目前为止,当HTTP会话在服务器端自动过期时,如何在客户端自动运行一些(JavaScript)代码？

我试图在Tomcat 7应用服务器上设置我的应用程序超时.首先我在web.xml中测试我的超时为一分钟

 <session-config>
       <session-timeout>1</session-timeout>
  </session-config> 

and I am using HttpSessionListener to make sure my Timeout is working fine.I declared my sessionListener Class in web.xml .

public class HttpSessionChecker implements HttpSessionListener {

    public void sessionCreated(HttpSessionEvent event) {
        System.out.printf("Session ID %s created at %s%n", event.getSession().getId(), new Date());
    }
    public void sessionDestroyed(HttpSessionEvent event) {
        System.out.printf("Session ID %s destroyed at %s%n", event.getSession().getId(), new Date());
    }
}

and In web.xml

<listener>
    <listener-class>com.test.util.HttpSessionChecker</listener-class>
</listener>

But when start my server and launch my application I see session …

我用表单打开一些选项卡，当我按下命令按钮时（会话过期一段时间后），我收到一条 java 脚本警报：

serverError: class javax.faces.application.ViewExpiredException viewId:/register.xhtml - 无法恢复 View /register.xhtml。

在 Firefox 上（本地 glassfish 4）

我已经添加了 ：

<error-page>
    <exception-type>javax.faces.application.ViewExpiredException</exception-type>
    <location>/index.xhtml?faces-redirect=true</location>
</error-page>

在我的web.xml但我没有重定向到我的索引。这是为什么 ？

编辑：示例按钮

<h:commandButton value="Register" action="#{userController.register}">
    <f:ajax execute="@form" render="@form" />
</h:commandButton>

UserController 是 ViewScoped

我正在尝试为所有ajax请求配置一个oncomplete方法,以便我可以处理会话超时.

我尝试添加以下脚本但它的工作方式与为p:ajax元素设置oncomplete属性的方式不同.每次发出Ajax请求时都不会执行.

$.ajaxSetup({method: post,
    complete: function(xhr, status, args){
        var xdoc = xhr.responseXML;
        if(xdoc == null){
            return;
        }
        errorNodes = xdoc.getElementsByTagName('error-name');

        if (errorNodes.length == 0) {
            return;
        }

        errorName = errorNodes[0].childNodes[0].nodeValue;
        errorValueNode = xmlDoc.getElementsByTagName('error-message');
        errorValue = errorValueNode[0].childNodes[0].nodeValue;

        alert(errorValue);
        document.location.href='${pageContext.request.contextPath}/login/login.jsf';
    }
});

任何帮助,将不胜感激
