JSF - 为受限制的页面实现过滤器

Question

I'm following answer by @BalusC to JSF 2.0: How to get the URL that is entered in the browser's address bar to restrict pages from users who are not logged in.

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
    }
}

web.xml:

<security-constraint>
    <web-resource-collection>
      <web-resource-name>Admin pages</web-resource-name>
      <url-pattern>/admin/*</url-pattern>
      <url-pattern>/restricted/*</url-pattern>
      <http-method>GET</http-method>
          <http-method>POST</http-method>
    </web-resource-collection>
    <auth-constraint>
      <role-name>ADMIN</role-name>
    </auth-constraint>
  </security-constraint>

  <security-constraint>
    <web-resource-collection>
      <web-resource-name>User pages</web-resource-name>
      <url-pattern>/restricted/*</url-pattern>
      <http-method>GET</http-method>
          <http-method>POST</http-method>
    </web-resource-collection>
    <auth-constraint>
      <role-name>ADMIN</role-name>
      <role-name>USER</role-name>
    </auth-constraint>
  </security-constraint>

   <!--login-config>
     <auth-method>FORM</auth-method>
     <realm-name>jdbc-realm</realm-name>
     <form-login-config>
       <form-login-page>/pages/login.xhtml</form-login-page>
       <form-error-page>/pages/error.xhtml</form-error-page>
     </form-login-config>
   </login-config-->

    <filter>
        <filter-name>RestrictPageFilter</filter-name>
        <filter-class>gov.denis.chanceryweb5.filter.RestrictPageFilter</filter-class>
    </filter>

    <filter-mapping>
        <filter-name>RestrictPageFilter</filter-name>
        <url-pattern>/restricted/*</url-pattern>
    </filter-mapping> 

glassfish-web.xml

<glassfish-web-app>
<security-role-mapping>
    <role-name>ADMIN</role-name>
    <group-name>ADMIN</group-name>
  </security-role-mapping>
  <security-role-mapping>
    <role-name>USER</role-name>
    <group-name>USER</group-name>
  </security-role-mapping>

realm in glassfish gui console:

When accessing my web app, in browser i see this for some reason? why?

Answer 1

You are seeing the dialog associated with the BASIC authentication method.

You currently have the login-config elements of your web.xml file commented out... so that configuration is not being applied.

GlassFish 3 servers have a default login-config that is used when a user deployed app specifies a security-constraint but does not specify a login config...

The effective login-config for your app actually looks something like this

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

The default login-config is specified in glassfish3/glassfish/domains/<your domain name here>/config/default-web.xml
