推荐答案
对于您的< p:menuitem/> ，请使用成果属性，该属性指定导航而不是 url 的情况下，它应与绝对而非JSF相关的url一起使用.在这里，您有一个基本的解释案例，基于@Daniel Camargo的建议代码:
For your <p:menuitem /> use an outcome attribute, which specifies the navigation case, instead of url, that's intended to be used with an absolute and not JSF related url. Here you've got a basic explanation case, based in @Daniel Camargo's suggested code:
tabs.xhtml:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
xmlns:h="http://xmlns.jcp.org/jsf/html"
xmlns:f="http://xmlns.jcp.org/jsf/core"
xmlns:p="http://primefaces.org/ui">
<h:head />
<h:body>
<f:metadata>
<f:viewParam name="index" value="#{index}" />
<f:event type="preRenderView" listener="#{bean.initPage}" />
</f:metadata>
<h:form>
<p:menubar>
<p:submenu label="Taskbox">
<!-- Different ways of passing the view param -->
<p:menuitem value="Inbox" outcome="tabs?index=0" />
<p:menuitem value="Sent" outcome="tabs.xhtml?index=1" />
<p:menuitem value="Trash" outcome="tabs">
<f:param name="index" value="2" />
</p:menuitem>
<!-- External url -->
<p:menuitem value="Google" url="http://www.google.com"
target="_blank" />
</p:submenu>
</p:menubar>
</h:form>
<h:form id="postForm">
<p:tabView id="tabViewPosts" widgetVar="tabPanel"
activeIndex="#{index}">
<p:tab title="Inbox" id="inboxTab">
A
</p:tab>
<p:tab title="Sent" id="sentTab">
B
</p:tab>
<p:tab title="Trash" id="trashTab">
C
</p:tab>
</p:tabView>
</h:form>
</h:body>
</html>
请注意 outcome 属性，在此让JSF Servlet评估目标URL.基本上，值为 tabs 的结果将在客户端显示为 basePath/tabs.xhtml .因此，基本上，您是将页面定向到自身，但是更改了 viewParam 值.
Note the outcome attribute here let's the JSF servlet evaluate the destination url. Basically, an outcome with value of tabs will get rendered as basePath/tabs.xhtml at client side. So basically you are making the page be directed to itself, but changing the viewParam value.
