如何在angular中写入子模块的布线？

ng generate module submodule-name

// src/app/submodule-name/submodule-name-routing.module.ts
import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { SubComponent } from './sub.component';

const routes: Routes = [
  { path: '', component: SubComponent }
];

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

// src/app/submodule-name/submodule-name.module.ts
import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { SubComponent } from './sub.component';
import { SubRoutingModule } from './submodule-name-routing.module';

@NgModule({
  declarations: [SubComponent],
  imports: [
    CommonModule,
    SubRoutingModule
  ]
})
export class SubmoduleNameModule { }

// src/app/app-routing.module.ts
import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';

const routes: Routes = [
  { path: 'submodule', loadChildren: () => import('./submodule-name/submodule-name.module').then(m => m.SubmoduleNameModule) }
];

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