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

import { DashboardPage } from './dashboard-page/component';
import { AccountPage } from './acct-page/component';

const appRoutes: Routes = [
    { path: 'dashboard',component: DashboardPage },{ path: 'accounts/:number',component: AccountPage},{ path: '',redirectTo: '/dashboard',pathMatch: 'full' },];

@NgModule({
    imports: [RouterModule.forRoot(appRoutes,{ enableTracing: false,useHash: true })],exports: [RouterModule],providers: []
})
export class AppRoutingModule { }

以下是我的app.module.ts：

import { BrowserModule } from '@angular/platform-browser';
import { RouterModule,Routes } from '@angular/router';
import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common'
import { FormsModule,ReactiveFormsModule } from '@angular/forms';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { HttpClientModule } from '@angular/common/http';
import { NgxChartsModule } from '@swimlane/ngx-charts';
import { DataTableModule } from "angular2-datatable";
import {  
  MatToolbarModule,MatToolbarRow,MatIconModule,MatSidenavModule,MatListModule,MatButtonModule,MatCardModule,MatMenuModule,MatGridListModule,MatInputModule,MatDatepickerModule,MatNativeDateModule,MatTableModule,MatTabsModule,MatCheckBoxModule
} from '@angular/material';
import { MatSelectModule } from '@angular/material/select';
import {MatExpansionModule} from '@angular/material/expansion';

import { AppComponent } from './app-component/app.component';
import { AppRoutingModule } from './app-routing.module';

import { DashboardPage } from './dashboard-page/component';
import { AccountPage } from './acct-page/component';


@NgModule({
    declarations: [
        AppComponent,DashboardPage,BreadcrumbComponent,AccountPage
    ],imports: [
        AppRoutingModule,RouterModule,BrowserModule,HttpClientModule,BrowserAnimationsModule,MatToolbarModule,CommonModule,DataTableModule,FormsModule,ReactiveFormsModule,MatExpansionModule,MatCheckBoxModule,MatSelectModule,NgxChartsModule
    ],providers: [],bootstrap: [AppComponent],entryComponents: [XMLContentDialog]
})
export class AppModule {
}

我使用了RouterModule.forRoot(appRoutes,{enableTracing：false,useHash：true})来启用哈希位置策略,但它不起作用.我在这里错过了什么吗？
