jsf - 如何使用 PrimeFaces 在 JSF 上重定向?

我正在尝试在 JSF 上做一个基本的安全系统,如果用户没有登录并尝试访问受限制的页面,他将被重定向到 login.xhtml。这是在 servlet 过滤器中完成的。

我的问题是,当使用 resp.sendRedirect("login.xhtml");登录页面丢失了所有资源,css,脚本等,所以页面显示没有任何样式。

网页.xml

登录.xhtml
<?xml version='1.0' encoding='UTF-8' ?>

<ui:define name="title">Login</ui:define>
<ui:define name="content">


</ui:define>
</ui:composition>

index.xhtml 看起来与登录相同,因为我仍在测试,可能是什么问题?

我正在使用 primefaces 2.2.1、glassfish 3.1、JSF 2.0

编辑:我刚刚注意到资源也使用 .xhtml 扩展名,所以它干扰了过滤器。

修复: if(req.getSession().getAttribute("func") == null && !pageRequested.contains("login.xhtml") && !pageRequested.contains("/javax.faces.resource"))
resp.sendRedirect("login.xhtml");

最佳答案

我经常使用这种方式直接从 Java Bean 重定向它:FacesContext.getCurrentInstance().getExternalContext().redirect(Url);
