在 angular 子模塊中設置根組件

Question

我有一個可用的應用程序路由，我想添加延遲加載。

這是有效的 app-routing.module.ts 文件（沒有延遲加載）：

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { LoginComponent } from './routes/login/login.component';
import { RegisterComponent } from './routes/register/register.component';
import { NavigationComponent } from './navigation/navigation.component';
import { DashboardComponent } from './routes/dashboard/dashboard.component';
import { ProfileComponent } from './routes/profile/profile.component';


const routes: Routes = [
  { path: 'login', component: LoginComponent },
  { path: 'register', component: RegisterComponent },
  {
    path: 'app', component: NavigationComponent, children: [
      { path: '', component: DashboardComponent },
      { path: 'profile', component: ProfileComponent }
    ]
  },
  { path: '**', redirectTo: 'app' }
];

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

現在我為“導航”部分（navigation.module.ts）創建了一個子模塊：

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { NavigationComponent } from './navigation/navigation.component';
import { DashboardComponent } from './routes/dashboard/dashboard.component';
import { ProfileComponent } from './routes/profile/profile.component';


const routes: Routes = [
  { path: '', component: DashboardComponent },
  { path: 'profile', component: ProfileComponent },
];

@NgModule({
  declarations: [
    NavigationComponent,
    DashboardComponent,
    ProfileComponent,
  ],
  imports: [
    CommonModule,
    FormsModule,
    ReactiveFormsModule,
  ],
  bootstrap: [NavigationComponent]
})
export class NavigationModule { }

這是新的 app-routing.module.ts

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { LoginComponent } from './routes/login/login.component';
import { RegisterComponent } from './routes/register/register.component';
import { NavigationComponent } from './navigation/navigation.component';
import { DashboardComponent } from './routes/dashboard/dashboard.component';
import { ProfileComponent } from './routes/profile/profile.component';


const routes: Routes = [
  { path: 'login', component: LoginComponent },
  { path: 'register', component: RegisterComponent },
  {
    path: 'app', loadChildren: () => import('./navigation/navigation.module').then(m => m.NavigationModule)
  },
  { path: '**', redirectTo: 'app' }
];

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

現在，當我調用例如 /app/profile 時，我有兩種不同的行為：

沒有延遲加載的行為（期望）：

<app-root>
  <router-outlet></router-outlet>
  <app-navigation>
    <!-- sidebar and toolbar content -->
    <router-outlet></router-outlet>
    <app-profile>
      <!-- profile content -->
    </app-profile>
  </app-navigation>
</app-root>

延遲加載的行為：

<app-root>
  <router-outlet></router-outlet>
  <app-profile>
    <!-- profile content -->
  </app-profile>
</app-root>

延遲加載怎么可能有相同的行為？

在 NavigationModule 中嘗試

const routes: Routes = [
  { path: '', component: NavigationComponent, children: [
    { path: '', component: DashboardComponent },
    { path: 'profile', component: ProfileComponent },
  ]
];
