使用 FeatureRoutingModule 的 forChild() 方法来定义特征路由。将 FeatureRoutingModule 导入到主应用程序模块，然后对于每个特征模块，使用要导航到特征模块的根路径的路由。在特征模块中，使用 FeatureRoutingModule 的 forChild() 方法来定义特征路由。

示例代码：

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

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

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

// feature.module.ts import { NgModule } from '@angular/core'; import { CommonModule } from '@angular/common'; import { FeatureComponent } from './feature.component'; import { FeatureRoutingModule } from './feature-routing.module';

@NgModule({ declarations: [FeatureComponent], imports: [ CommonModule, FeatureRoutingModule ] }) export class FeatureModule { }

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

const routes: Routes = [ { path: 'feature', loadChildren: () => import('./feature/feature.module').then(m => m.FeatureModule) } ];

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

// app.module.ts 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 { }
