Angular 5在现有的标记中动态插入组件？

import { Component, ComponentFactoryResolver, ViewChild, ViewContainerRef } from '@angular/core';
import { DynamicComponent } from './dynamic.component';

@Component({
  selector: 'app-root',
  template: `
    <div>
      <h1>动态插入组件示例</h1>
      <button (click)="insertComponent()">插入组件</button>
      <div #container></div>
    </div>
  `,
})
export class AppComponent {
  @ViewChild('container', { read: ViewContainerRef }) container: ViewContainerRef;

  constructor(private componentFactoryResolver: ComponentFactoryResolver) {}

  insertComponent() {
    const componentFactory = this.componentFactoryResolver.resolveComponentFactory(DynamicComponent);
    const componentRef = this.container.createComponent(componentFactory);
  }
}
