如何从一个angular 2应用程序加载另一个angular 2应用程序？

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { AppComponent } from './app.component';
import { AnotherAppComponent } from './another-app.component';

const routes: Routes = [
  { path: '', component: AppComponent },
  { path: 'another-app', component: AnotherAppComponent }
];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})
export class AppRoutingModule { }

<a routerLink="/another-app">Load Another App</a>

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';

@NgModule({
  imports: [BrowserModule, AppRoutingModule],
  declarations: [AppComponent],
  bootstrap: [AppComponent]
})
export class AppModule { }

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AnotherAppComponent } from './another-app.component';

@NgModule({
  imports: [BrowserModule],
  declarations: [AnotherAppComponent],
  bootstrap: [AnotherAppComponent]
})
export class AnotherAppModule { }

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

@Component({
  selector: 'app-another',
  template: '<h1>Another App</h1>'
})
export class AnotherAppComponent { }
