export class DashboardModule { }
从'@angular/core'导入{NgModule}；
从“@angular/common”导入{CommonModule}；
从'@angular/forms'导入{FormsModule，ReactiveFormsModule}；
从'@angular/router'导入{RouterModule}；
从'@angular/http'导入{HttpModule}；
从“./dashboard.component”导入{DashboardComponent}；
从“./shared/dashboard.service”导入{DashboardService}；
