如何使用默认路由登录屏幕- Angular 4

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';

import { LoginComponent } from './login.component';
import { HomeComponent } from './home.component';

const routes: Routes = [
  { path: '', redirectTo: '/login', pathMatch: 'full' }, // 定义默认路由
  { path: 'login', component: LoginComponent },
  { path: 'home', component: HomeComponent }
];

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

<!-- app.component.html -->
<router-outlet></router-outlet>
