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"); 登录页面丢失所有资源,css,脚本等。所以页面显示没有任何样式。

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