index.html 改为 index.xhtml

index.html change to index.xhtml

尝试注销我的应用程序时出现以下错误消息:

com.sun.faces.context.FacesFileNotFoundException: /index.xhtml Not Found in ExternalContext as a Resource

要注销,我将在 PhaseListener.beforePhase(PhaseEvent phaseEvent) 中执行以下步骤:

// Redirect to index.html
NavigationHandler nh = fctx.getApplication().getNavigationHandler();
String action_outcome = "/index.html";
nh.handleNavigation(fctx, null, action_outcome);

我的web.xml如下:

我的应用程序中没有 index.xhtml,但我有并且想保留它 index.html 文件。

为什么我给 NavigationHandler 的 outcome_action 重命名为 index.xhtml?

我怎样才能避免它?

NavigationHandler 需要 JSF 页面,而不是非 JSF 页面。此外,您实际上根本没有发送真正的重定向,这与代码注释在那里所说的相反。你只是在这里做一个前锋。

执行真正的重定向可以解决您的问题。具体操作如下:

ExternalContext ec = FacesContext.getCurrentInstance().getExternalContext();
ec.redirect(ec.getRequestContextPath() + "/index.html");

与具体问题无关,在阶段侦听器中执行授权工作很糟糕。您是否考虑过 servlet 过滤器?
