我的module-routing.ts如下

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { RouterModule, Routes } from '@angular/router'
import { PatientlistComponent } from './patientlist/patientlist.component';
import { AddpatientComponent } from './addpatient/addpatient.component';

export const routes: Routes = [
  //{ path: '', component: PatientlistComponent, pathMatch: 'full' },
  { path: 'patientlist', component: PatientlistComponent },
  { path: 'addpatient', component: AddpatientComponent }
 ]; 



@NgModule({
  imports: [
    CommonModule,
    RouterModule.forRoot(routes)
  ],
  exports: [RouterModule],  
  declarations: []
})
a

export class AppRoutingModule { }

和appModule

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { HttpModule } from '@angular/http';
import { HttpClientModule } from '@angular/common/http';
import { ReactiveFormsModule } from '@angular/forms'

//import { AppComponent } from './app.component';
import { PatientlistComponent } from './patientlist/patientlist.component';
import { AppRoutingModule } from './/app-routing.module';
import { AddpatientComponent } from './addpatient/addpatient.component';
import { PatientServiceService } from './patient-service.service';

@NgModule({
  declarations: [
   // AppComponent,
    PatientlistComponent,
   AddpatientComponent
  ],
  imports: [
    BrowserModule,
    HttpModule,
    HttpClientModule,
    AppRoutingModule
  ],
  providers: [PatientServiceService],
  //bootstrap: [AppComponent]
  bootstrap: [PatientlistComponent]
})
export class AppModule { }

请帮助解决这个问题TIA

Answer 1

您尚未设置正确的默认路径路径

你需要设置

{  path: 'your default path ',
    redirectTo: 'redirect url',
    pathMatch: 'full', 
}

Answer 2

您缺少应用程序默认（/）路由。请添加默认路由，希望它能正常工作。
