javaee IsUserInRole 总是返回 false jsf

Question

我在很多帖子中都发现了这个问题，但我找不到解决方案。我有一个基于领域的身份验证，并且有两个映射的角色 USERS 和 ADMINS。登录正常，但如果我尝试使用

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

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

这是 web.xml 文件

将以下内容添加到您的 web.xml 文件中:

<security-role>
    <role-name>USERS</role-name>
</security-role>
<security-role>
    <role-name>ADMINS</role-name>
</security-role>
