如何在angular2中实现html5路由？

npm install @angular/router

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { RouterModule } from '@angular/router';

@NgModule({
  imports: [
    BrowserModule,
    RouterModule.forRoot([]) // 导入RouterModule并调用forRoot方法
  ],
  declarations: [AppComponent],
  bootstrap: [AppComponent]
})
export class AppModule { }

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

@Component({
  selector: 'app-root',
  template: `
    <h1>My App</h1>
    <nav>
      <a routerLink="/home">Home</a>
      <a routerLink="/about">About</a>
    </nav>
    <router-outlet></router-outlet>
  `
})
export class AppComponent { }

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

import { HomeComponent } from './home.component';
import { AboutComponent } from './about.component';

const routes: Routes = [
  { path: 'home', component: HomeComponent },
  { path: 'about', component: AboutComponent }
];

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

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { RouterModule } from '@angular/router';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { HomeComponent } from './home.component';
import { AboutComponent } from './about.component';

@NgModule({
  imports: [
    BrowserModule,
    RouterModule.forRoot([]),
    AppRoutingModule // 导入AppRoutingModule
  ],
  declarations: [
    AppComponent,
    HomeComponent,
    AboutComponent
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }
