如何使用PrimeFaces重定向JSF？

我正在尝试在JSF上建立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”)时;登录页面丢失所有资源,CSS,脚本等.因此页面显示没有任何样式.

web.xml中

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">

<filter-mapping>
<filter-name>restrict</filter-name>
<url-pattern>*.xhtml</url-pattern>
<servlet-name>Faces Servlet</servlet-name>
</filter-mapping>
</web-app>

的template.xhtml

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

    <div id="menu">

            <p>Jorge Luis</p>
        </ui:insert>
    </div>
</body>
</html>

login.xhtml

<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"     "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<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,因为我还在测试,可能是什么问题？

来自chrome控制台的错误

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,因此它干扰了过滤器.

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

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