Dynamic Ionic2动态导航

我正在构建一个应用程序，其中数据来自服务器。菜单是动态的，服务器可以根据用户配置文件发送不同的菜单。我永远不知道菜单项将包含什么组件/页面，我只需要让该组件/页面可用

主要的问题是我需要导入很多组件/页面，我不想在每个组件/页面中都导入这些内容

我创建了一个服务，在其中进行所有导入，并存在一个方法来返回正确的组件，因此navController可以导航

import { Injectable } from '@angular/core';

//Import navigation pages
import { NotificationsPage } from "./../pages/notifications/notifications";
import { ClubPage } from "./../pages/club/club";
import { ActivitiesPage } from "./../pages/activities/activities";
import { NewsPage } from "./../pages/news/news";
import { CalendarPage } from "./../pages/calendar/calendar";
import { NewsletterPage } from "./../pages/newsletter/newsletter";
import { SettingsPage } from "./../pages/settings/settings";
import { FavoritesPage } from "./../pages/favorites/favorites";
import { SubmenuPage } from "./../pages/submenu/submenu";
import { ContentDetailsPage } from "./../pages/contentdetails/contentdetails";

@Injectable()
export class ViewNavigatorService
{
      public NOTIFICATIONS:string = "notifications";
      public CLUB:string = "club";
      public ACTIVITIES:string = "activities";
      public NEWS:string = "news";
      public CALENDAR:string = "calendar";
      public NEWSLETTER:string = "newsletter";
      public SETTINGS:string = "settings";
      public FAVORITS:string = "favorits";

      public SUBMENU:string = "submenu";
      public CONTENT_DETAILS:string = "content-details";

      public GetComponent(page:string, data?:any):any
      {
            let Component = null;

            switch (page) 
            {
                  case this.NOTIFICATIONS:      Component = NotificationsPage;     break;
                  case this.CLUB:               Component = ClubPage;              break;
                  case this.ACTIVITIES:         Component = ActivitiesPage;        break;
                  case this.NEWS:               Component = NewsPage;              break;
                  case this.CALENDAR:           Component = CalendarPage;          break;
                  case this.NEWSLETTER:         Component = NewsletterPage;        break;
                  case this.SETTINGS:           Component = SettingsPage;          break;
                  case this.FAVORITS:           Component = FavoritesPage;         break;
                  case this.SUBMENU:            Component = SubmenuPage;           break;
                  case this.CONTENT_DETAILS:    Component = ContentDetailsPage;    break;

                  default:                      Component = null;                  break;
            }

            return Component;
      }
}

如果我只在父页面中注入服务，它可以工作，但是如果我也在子页面中注入服务，我会得到以下错误：

无法解析子菜单页的所有参数：（NavController、NavParams、PopoverController、AlertController、ModalController，？）

那个？应该是“ViewNavigatorService”

为什么会发生这种错误

有更好的方法吗？当应用程序使用动态导航时，您使用的是什么
