javax.faces.application.ViewExpiredException和错误页面不起作用

如何解决javax.faces.application.ViewExpiredException和错误页面不起作用

|| 我按照以下步骤设置了Web应用程序：

 <error-page>
        <exception-type>javax.faces.application.ViewExpiredException</exception-type>
        <location>/WEB-INF/include/viewExpired.html</location>
</error-page>

以便在引发viewExpiredException时显示以上错误页面。但是，当我重新启动服务器并在\“ left-open \”页面上提交ajax请求时，控制台中将引发异常，并且不会显示我的错误页面。这是来自控制台的堆栈跟踪：

解决方法

因此，您要处理标准JSF 2.0实现上的Ajax错误吗？标准的JSF实现没有为此提供现成的组件。例如，在PrimeFaces中，您可以使用<p:ajaxStatus>组件。但是，JSF 2.0规范在第13.3.6.2章中概述了以下内容： 13.3.6.2处理所有Ajax请求的错误 JavaScript API提供了jsf.ajax.addOnError函数，该函数可用于注册JavaScript函数，当任何Ajax请求/响应发生错误时，该函数都会得到通知。有关更多详细信息，请参见第14.4节“注册回调函数”。 jsf.ajax.addOnError函数接受一个JavaScript函数参数，该参数将是在任何Ajax请求/响应周期中发生错误时通知。 [P1-start-event]实施必须确保必须根据表14-5中概述的错误来调用已注册的JavaScript函数。 “错误” 您可以在这里找到Mojarra开发人员之一的博客，其中包含如何显示Ajax状态的基本示例。这是相关的摘录：

<h3> Status:</h3>
<textarea id=\"statusArea\" cols=\"40\" rows=\"10\" readonly=\"readonly\" />

一个简单的文本区域，甚至没有被钩住进入后端服务器数据模型。然后在我们的javascript中（对于演示，在单独加载的文件中可以很容易地出现在页面中）我们有：

var statusUpdate = function statusUpdate(data) {
    var statusArea = document.getElementById(\"statusArea\");
    var text = statusArea.value;
    text = text + \"Name: \"+data.source.id;
    if (data.type === \"event\") {
        text = text +\" Event: \"+data.name+\"\\n\";
    } else {  // otherwise,it\'s an error
        text = text + \" Error: \"+data.name+\"\\n\";
    }
    statusArea.value = text;
};

// Setup the statusUpdate function to hear all events on the page
jsf.ajax.addOnEvent(statusUpdate);
jsf.ajax.addOnError(statusUpdate);

您也可以使用JS重定向到错误页面。

window.location = \'/errors/500.xhtml\';
