玩2.5生产模式ebean finder错误

Question

当应用程序尝试从数据库中查询数据时，Play 2.5.3生产模式会抛出以下异常。

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { RouterModule } from '@angular/router';
import { HttpModule } from '@angular/http';

import { DashboardComponent } from './dashboard.component';
import { DashboardService } from './shared/dashboard.service';

@NgModule({
imports: [
  RouterModule, <-------
  CommonModule,
  FormsModule,
  ReactiveFormsModule,
  HttpModule
],
declarations: [
  DashboardComponent
],
exports: [
  DashboardComponent,
  CommonModule,
  FormsModule
],
providers: [
  // DashboardService
],
bootstrap: [
  // DashboardComponent
]
})
export class DashboardModule { }

任何人都可以帮我解决这个问题。
