小编gcc*_*gcc的帖子

我已经在很多帖子中找到了这个问题，但是我找不到解决方案。我有一个基于领域的身份验证，并具有映射到USERS和ADMINS的两个角色。登录正常工作，但是如果我尝试使用

FacesContext context = FacesContext.getCurrentInstance();
    ExternalContext externalContext = context.getExternalContext();
    if(externalContext.getRemoteUser() != null && externalContext.isUserInRole("USERS")){
        return true;
    }

即使我已登录，isUserInRole始终返回false。我该如何解决这个问题？
