这将

销毁会话
，由于bean是会话作用域，所有数据都将丢失

}

<p:commandButton action="#{userBB.logout}" value="log out" />

 Faces.redirect("login.xhtml?msg=You have been logged out sucessfully");

在您的xhtml中
<h:outputText id="message" value="#{param['msg']}"/>



如果不想在url中显示
创建另一个文件logout.xhtml
（实际上logout.xhtml将具有与login.xhtml相同的代码，只需添加所需的额外行即可）
您还可以使用url参数隐藏mesage
Faces.redirect（“login.xhtml？Faces redirect=true&logoutMsg=true”）；

和xhtml


为什么它不显示我的注销消息
因为您已经将其指定为会话范围bean的属性，然后使会话无效并发送重定向。会话的失效将破坏会话范围和其中存储的所有对象，包括会话范围的托管bean。此后的重定向将创建一个全新的请求和会话，所有会话范围的托管bean都将重新创建，所有属性都设置为默认值
这种方法有两个问题：
使用
而不是
显示消息
将消息存储在会话作用域中，而不是存储在会话作用域中
要解决您的问题，请使用
显示消息，并使用FacesContext#addMessage（）
，或者使用OmniFaces的实用程序类将消息添加到faces上下文。您可以使用
仅显示全局消息（即带有null
客户端ID的消息）。您可以使用来告诉JSF将当前请求的所有消息存储在flash作用域中
因此，总的来说，这应该做到：
<h:messages id="messages" globalOnly="true" />

对于感兴趣的人来说，下面是使用“普通JSF”的情况：
重要的一点是。您至少需要2.1.27才能消除所有这些问题。
您管理的bean的范围？？？会话范围。我刚刚编辑了我的问题OK。如何修复此问题？如何在url位置栏中隐藏邮件？我今天将进行这些更改。谢谢你，巴卢斯克。使用此解决方案，我遇到了以下问题：当会话自动关闭后需要登录时，下次登录时会出现注销消息。您是如何执行注销的？通过命令按钮/链接，对吗？您使用的是哪个JSF impl/版本？
