Jsf 2 JSF2.2.10，Tomcat8，JAAS登录失败

我试图使用JDBC领域在Tomcat8上实现JSF2JAAS登录。我已使用以下资源为JDBC登录配置了数据库中的表： My web.xml：

</security-role>
<security-role>
    <role-name>user</role-name>

错误发生在以下位置：

request.login(username, password);

错误为“登录失败”

如何使登录成功？

您的

在哪里？你定义了一个领域吗？我忘记的是实现实际的JAAS登录模块lol。谢谢你的帮助

    public void login() throws IOException {
    ExternalContext externalContext = externalContext();
    HttpServletRequest request = (HttpServletRequest) externalContext.getRequest();
    try {
        request.login(username, password);
    } catch (ServletException e) {
        String loginErrorMessage = e.getLocalizedMessage();
        facesContext().addMessage(null, new FacesMessage(loginErrorMessage));
    }
}

request.login(username, password);
