javax.faces.application.ViewExpiredException和错误页面不工作

Question

我设置我的web应用程序如下:

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

以便在抛出viewExpiredException时显示上述错误页面。

但是，当我重新启动服务器并在"左打开"页面上提交ajax请求时，在控制台中抛出异常，并且不显示我的错误页面。

下面是来自控制台的堆栈跟踪:

javax.faces.application.ViewExpiredException: viewId:/contact.jsf - La vue /contact.jsf na pas pu être restaurée.

有谁有什么线索吗?

那么您想在标准JSF 2.0实现上处理Ajax错误?标准JSF实现没有为此提供现成的组件。例如，在PrimeFaces中，您可以为此使用<p:ajaxStatus>组件。然而，JSF 2.0规范在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，可以用来注册一个JavaScript函数，当任何Ajax请求/响应发生错误时，该函数将被通知。请参阅第14.4节"注册回调函数"了解更多细节。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]实现必须保证被注册的JavaScript函数必须按照表14-5中列出的错误来调用"错误"

你可以在这里找到一个Mojarra开发人员的博客，其中包含了如何显示ajax状态的基本示例。以下是相关内容的摘录:

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

一个简单的文本区，甚至没有钩到后端服务器数据模型。

然后在我们的javascript(用于演示)中，在一个单独加载的文件中也可以很容易地在页)我们:

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);

你也可以使用JS重定向到错误页面。

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