有人可以告诉我如何获取屏幕名称

ThemeDisplay themeDisplay;
HttpServletRequest httpRequest;
themeDisplay = (ThemeDisplay) httpRequest.getAttribute(WebKeys.THEME_DISPLAY);
            User user = null;
            long userId1 = themeDisplay.getUserId();
            user = UserLocalServiceUtil.getUserById(userId1);
          String screenname1 = user.getScreenName();

Answer 1

我在java类中使用了以下代码，我现在可以使用下面的代码获取屏幕名称

现在＆＃34;用户＆＃34;对象在变量_originalScreenName

中具有屏幕名称

  HttpServletRequest request;
   long companyID = PortalUtil.getCompanyId(request);
   User user = UserLocalServiceUtil.getUserByEmailAddress(companyID, EmailID);
