Angular 2/4 :如何在不重新创建组件的情况下更改路由

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

const routes: Routes = [
  { path: 'home', component: HomeComponent },
  { path: 'about', component: AboutComponent },
  // 其他路由配置
];

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

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

constructor(private router: Router) { }

this.router.navigate(['/about']);

this.router.navigate(['/user', 1]);

this.router.navigate(['/search'], { queryParams: { q: 'angular' } });
