JSF - 实施受限页面过滤器

我正在关注@BalusC 的回答JSF 2.0：如何获取在浏览器地址栏中输入的 URL https://stackoverflow.com/questions/4105263/jsf-2-0-how-to-get-the-url-that-is-entered-in-the-browsers-address-bar限制未登录用户的页面。

Filter:

public class RestrictPageFilter implements Filter{
    FilterConfig fc;

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
        fc=filterConfig;
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        HttpServletRequest httpreq = (HttpServletRequest) request;
        HttpServletResponse httpres = (HttpServletResponse) response;
        if (httpreq.getUserPrincipal() == null) {
            httpreq.getSession().setAttribute("from", httpreq.getRequestURI());
            httpres.sendRedirect("/pages/login.xhtml");
        } else {
            chain.doFilter(request, response);
        }
    }

    @Override
    public void destroy() {
        // TODO Auto-generated method stub
    }
}

realm in glassfish gui console:

当访问我的网络应用程序时，在浏览器中我出于某种原因看到了这个？为什么？

您将看到与 BASIC 身份验证方法关联的对话框。

您当前已注释掉 web.xml 文件的 login-config 元素...因此不会应用配置。

GlassFish 3 服务器有一个默认登录配置，当用户部署的应用程序指定安全约束但未指定登录配置时使用该配置...

您的应用程序的有效登录配置实际上看起来像这样

  <login-config>
    <auth-method>BASIC</auth-method>
    <realm-name>file</realm-name>
  </login-config>

默认登录配置在中指定glassfish3/glassfish/domains/<your domain name here>/config/default-web.xml
