可以使用路由配置中的“ReuseStrategy”来禁用Angular在导航时重载组件。下面是一个示例代码：

import { RouteReuseStrategy, ActivatedRouteSnapshot, DetachedRouteHandle } from '@angular/router';

export class CustomReuseStrategy implements RouteReuseStrategy {

  shouldDetach(route: ActivatedRouteSnapshot): boolean {
    return false;
  }

  store(route: ActivatedRouteSnapshot, detachedTree: DetachedRouteHandle): void {}

  shouldAttach(route: ActivatedRouteSnapshot): boolean {
    return false;
  }

  retrieve(route: ActivatedRouteSnapshot): DetachedRouteHandle|null {
    return null;
  }

  shouldReuseRoute(future: ActivatedRouteSnapshot, curr: ActivatedRouteSnapshot): boolean {
    return future.routeConfig === curr.routeConfig;
  }
}

在要使用该策略的模块中，只需将其提供给路由模块即可：

import { NgModule } from '@angular/core';
import { RouterModule, RouteReuseStrategy } from '@angular/router';
import { CustomReuseStrategy } from './custom-reuse-strategy';

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule],
  providers: [{provide: RouteReuseStrategy, useClass: CustomReuseStrategy}]
})
export class AppRoutingModule {}

这将确保在导航时不会重载组件。
