Angular 1服务无法在Angular2

Question

我在ng1中实现了一个LoginInfoService。

要在混合角度应用程序中使用它，根据文档，我已完成以下操作 -

创建了应用模块

import { NgModule, ElementRef} from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { UpgradeModule } from '@angular/upgrade/static';
@NgModule({
    imports: [BrowserModule,
    HttpModule,
    JsonpModule,
    UpgradeModule
],
declarations: [... ],
providers: [
    LoginInfoService,
    { provide: 'LoginInfoService', useFactory: (i: any) =>     i.get('LoginInfoService'), deps: ['$injector'] },
],
entryComponents:[... ]

})
export class AppModule {
    ngDoBootstrap() { /* this is a placeholder to stop the boostrapper from     complaining */
}
}

1. 创建了一个包装器ng2服务，如下所示 -

   import {Injectable, Inject} from "@angular/core";
   
   @Injectable()
   export class LoginInfoService {
   
       constructor( @Inject("LoginInfoService") public loginInfoService:   LoginInfoService) {
       return loginInfoService;
   }
   isDirectvInFocus() {
       return this.loginInfoService.isDirectvInFocus();
   
   }
   isWirelessInFocus() {
       return this.loginInfoService.isWirelessInFocus();
   
   }
   getAccountInFocus() {
       return this.loginInfoService.getAccountInFocus();
   }
   getLoginType() {
       return this.loginInfoService.getLoginType();
   }
   

   }

主要是

 platformBrowserDynamic().bootstrapModule(AppModule).then(platformRef => {
    const upgrade = platformRef.injector.get(UpgradeModule) as UpgradeModule;
    upgrade.bootstrap(document.documentElement, ['myApp']);//this is angular1 module
});

收到以下错误 -

zone.js:405 Unhandled Promise rejection: No provider for LoginInfoService! ; Zone: ; Task: Promise.then ; Value: Error: No provider for LoginInfoService!
