Angular 2：在注入Router之前引导至少一个组件

Promise rejection: Bootstrap at least one component before injecting Router.

main.ts：

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app.module';
platformBrowserDynamic().bootstrapModule(AppModule);

app.module.ts：

@NgModule({
  imports: [
    BrowserModule,routing,SharedModule.forRoot()
  ],declarations: [
    AppComponent,ErrorComponent
  ],bootstrap: [AppComponent]
})
export class AppModule {}

shared.module.ts：

@NgModule({
  imports: [CommonModule,RouterModule,HttpModule,FormsModule,ReactiveFormsModule],declarations: [TranslatePipe,DateToStringPipe,HeaderComponent,FooterComponent],exports: [TranslatePipe,CommonModule,ReactiveFormsModule,FooterComponent]
})
export class SharedModule {

  static forRoot(): ModuleWithProviders {

    return {
      ngModule: SharedModule,providers: [
        FeedbackService,CookieService,AuthService,LoggerService,RouteGuard,{
          provide: TranslateLoader,useFactory: (http: Http) => new TranslateStaticLoader(http,'app/languages','.json'),deps: [Http]
        },TranslateService,SearchService,SharedComponent,FooterComponent
      ]
    };

  }

}

@NgModule({
  exports: [ SharedModule],providers: []
})
export class SharedRootModule {}

app.component.ts：

export class AppComponent extends SharedComponent implements OnInit {

constructor(
    _feedbackService: FeedbackService,_loggerService: LoggerService,_translateService: TranslateService,_authService: AuthService,_router: Router
) {

    super(
        _feedbackService,_loggerService,_translateService,_authService,_router
    );

}

最后是shared.component.ts：

constructor(
    protected _feedbackService: FeedbackService,protected _loggerService: LoggerService,protected _translateService: TranslateService,protected _authService: AuthService,protected _router: Router
) {

}

我尝试使用没有SharedComponent扩展的AppComponent,如下所示：

export class AppComponent implements OnInit {

constructor(){
}

但这仍然会产生同样的问题.
