Question

我正在学习Angular并且相当新。我目前正在处理一个项目，刚刚完成了我的路由设置，但现在我无法在内容位于app.component之前看到网页上的任何内容。 html文件。

然后将其移动到buttons.component.ts文件中的模板。

有人可以告诉我为什么没有输出？

app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import {BrowserAnimationsModule} from '@angular/platform-browser/animations';
import { NgModule } from '@angular/core';


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

import { AppComponent } from './app.component';

const routes: Routes= [
  {path: 'demo', loadChildren: './demo/demo.module#DemoModule'},
  {path: '**', redirectTo: 'demo'}
]

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    BrowserAnimationsModule,
    RouterModule.forRoot(routes),
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

---- demo.module.ts

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';

import { MaterialModule } from '../shared/material.module';
import { FormsModule } from '@angular/forms';

import { DemoRoutingModule } from './demo-routing.module';
import { ButtonsComponent } from './buttons/buttons.component';
import { FlexboxComponent } from './flexbox/flexbox.component';


@NgModule({
  imports: [
    CommonModule,
    DemoRoutingModule,
    FormsModule,
    MaterialModule
  ],
  declarations: [ButtonsComponent, FlexboxComponent]
})
export class DemoModule { }

---- demo.routing.module.ts

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import {ButtonsComponent} from './buttons/buttons.component';
import {FlexboxComponent} from './flexbox/flexbox.component';

const routes: Routes = [
    {path: 'buttons', component: ButtonsComponent},
    {path: 'flexbox', component: FlexboxComponent},
    { path: '**', redirectTo: 'buttons'}
];

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

----- buttons.component.ts

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

@Component({
  selector: 'app-buttons',
  template: `
  <button mat-button>
     <mat-icon>face</mat-icon>  
     Click me!
  </button>
<mat-checkbox>Check me!</mat-checkbox>
  `,
  styles: []
})
export class ButtonsComponent {

}
