一旦创建了reducer，就可以配置Angular应用程序了。 在您应用的主模块中，简单的将StoreModule.provideStore() 调用添加到@NgModule的导入中：
app/app.module.ts
import {BrowserModule} from '@angular/platform-browser';
import {NgModule} from '@angular/core';
import {FormsModule} from '@angular/forms';
import {HttpModule} from '@angular/http';
import {StoreModule} from '@ngrx/store';
import {EffectsModule} from '@ngrx/effects';
import 'rxjs/Rx';
import {rootReducer} from './store/rootReducer';
import {CounterActions} from './store/actions';
import {CounterEffects} from './store/effects';
import {AppComponent, CounterComponent} from './components';
import {CounterService} from './services';
@NgModule({
imports: [
BrowserModule,
FormsModule,
HttpModule,
StoreModule.provideStore(rootReducer)
],
declarations: [
AppComponent,
CounterComponent
],
providers: [
CounterActions,
CounterService
],
bootstrap: [AppComponent]
})
export class AppModule {
}
