如何在*ngIf中捕获路由

<div *ngIf="isRouteMatch('/example')">显示内容</div>

import { Component } from '@angular/core';
import { ActivatedRoute } from '@angular/router';

@Component({
  selector: 'app-example',
  templateUrl: './example.component.html',
  styleUrls: ['./example.component.css']
})
export class ExampleComponent {
  constructor(private route: ActivatedRoute) {}

  isRouteMatch(path: string): boolean {
    return this.route.snapshot.routeConfig.path === path;
  }
}
