我的RC5应用程序中出现此错误：
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.
Angular认为没有必要在模块级注入Router,在加载至少一个组件后注入Router是合理的.我怀疑至少有一个服务必须注入路由器,路由器提供给加载的模块,这会导致此错误.您可以做的是将使用路由器的服务注入应用程序组件,因此首先加载至少一个组件,并且所有子组件将从应用程序组件继承该服务.
