如何在Angular 2中不带参数地访问routerlink

<a routerLink="/path">Link</a>

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

import { ComponentName } from './component-path';

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

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

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

@Component({
  selector: 'app-component',
  templateUrl: './component-path.html',
  styleUrls: ['./component-path.css']
})
export class ComponentName {
  // 组件逻辑代码
}
