自定义/扩展Liferay忘记密码页面

Question

任何人都有自定义ForgotPasswordAction的解决方案吗？我的最终目标是允许用户输入用户名或电子邮件，以便能够检索他们忘记的密码。我已经覆盖了ForgotPassword.java中的getUser（ActionRequest请求）方法，如下所示：

protected User getUser(ActionRequest actionRequest)
            throws Exception {

            ThemeDisplay themeDisplay = (ThemeDisplay)actionRequest.getAttribute(
                WebKeys.THEME_DISPLAY);

            //CUSTOM
            String fgtPass = ParamUtil.getString(actionRequest, "fgtpass");
            String authType = null;

            if (Validator.isNull(authType)) {
                Company company = PortalUtil.getCompany(actionRequest);
                authType = company.getAuthType();
            }

            User user = null;

            if ( fgtPass.indexOf("@") != -1 && fgtPass.indexOf(".") != -1 ) {
                //If the login looks like an email, use the email authType constant.
                authType = CompanyConstants.AUTH_TYPE_EA;
                user = UserLocalServiceUtil.getUserByEmailAddress(
                    themeDisplay.getCompanyId(), fgtPass);
            } else {
                //If it doesn't look like an email, use the screen name authType constant.
                authType = CompanyConstants.AUTH_TYPE_SN;
                user = UserLocalServiceUtil.getUserByScreenName(
                        themeDisplay.getCompanyId(), fgtPass);
            } 

            //End CUSTOM

            return user;
        }
    }

这可以根据初始忘记密码屏幕上的屏幕名称或电子邮件对用户进行身份验证，但一旦进入提醒查询页面，就无法处理用户。我很确定我无法，因为fgtPass字段仅存在于初始忘记密码屏幕而不存在于查询页面上。有没有办法坚持这个用户？这是相应的.jsp：

<%
User user2 = (User)request.getAttribute(ForgotPasswordAction.class.getName());

if (Validator.isNull(authType)) {
    authType = company.getAuthType();
    System.out.println(authType);
}

if (user2 == null) {
    System.out.println("User is null.");
} else {
    System.out.println(user2.getScreenName());
}

任何线索？
