PrimeFaces Custom Error pages

Question

在我的PrimeFaces项目中，我需要为常规响应错误状态代码（例如401和404）提供一些常规错误页面。有人知道如何解决吗？

It's not handled by JSF, it's handled by the servlet container. You can specify them by <error-page> in web.xml .

<error-page>
    <error-code>401</error-code>
    <location>/errors/401.xhtml</location>
</error-page>
<error-page>
    <error-code>404</error-code>
    <location>/errors/404.xhtml</location>
</error-page>

If you'd like to navigate to them from inside JSF action methods, then you can use ExternalContext#responseSendError() for this.

externalContext.responseSendError(401, "You are not authorized.");
