在App-Routing.module.ts上加载默认页面的Angular Lazy加载

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { HomeComponent } from './home/home.component';
import { DefaultComponent } from './default/default.component';

const routes: Routes = [
  { path: '', component: HomeComponent },
  { path: 'default', component: DefaultComponent },
  // 其他路由配置...
];

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

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

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

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

@Component({
  selector: 'app-home',
  template: `
    <h1>Welcome to Home Page</h1>
    <button (click)="loadDefaultPage()">Go to Default Page</button>
  `
})
export class HomeComponent {

  constructor(private router: Router) { }

  loadDefaultPage() {
    this.router.navigate(['/default']);
  }

}
