Angular 我的ngrx效应赢了'；不要采取行动

我的效果是：

  @Effect()
  loadSubmissionFiles$: Observable<Action> = this.actions$
    .instanceOf(SubmissionFileActions.LoadSubmissionFiles)
    .switchMap(
      action => {
        console.log('action', action)
        var queryParams = action.deliverableTransactionId ? action.deliverableTransactionId : null;
        return this.submissionFileHttpService.loadSubmissionFiles(queryParams)
          .map(
            (res) => {
              return new SubmissionFileActions.LoadSubmissionFilesSuccess(res);
            })
          .catch((err) => {
            return Observable.of(new SubmissionFileActions.LoadSubmissionFilesFailure(err));
          });
      });

我做错了什么？这是angular5。您应该在应用程序根导入中注册效果

你登记了吗？你登记了吗？

case SubmissionFileActions.LoadSubmissionFiles:

@NgModule({
 imports: [EffectsModule.forRoot([YourEffects])]
})
export class AppModule {}
