Question

我正在尝试添加新模块，以使我的角度应用程序更加模块化和延迟加载。

app.module

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { HttpModule,BrowserXhr } from "@angular/http";
import { LabService } from './lab/lab.service';
import { FormsModule }   from '@angular/forms';
import { AppComponent }   from './app.component';
import { OphistoryModule } from './Ophistory/ophistory.Module' //after adding this module ERROR is thrown

@NgModule({
  imports:[ 
    BrowserModule,
    HttpModule,
    FormsModule,
    RouterModule.forRoot([
      {path: 'labDetails/:labName',component:LabDetailsComponent},
      {path:'showRoboLog/:labName',component:RoboLogComponent},
      {path:'',component:LabComponent}
    ]),
   OphistoryModule
 ],
 declarations: [ 
   AppComponent
 ],
 bootstrap:[ AppComponent ]
})
export class AppModule {}

app.component

import { Component } from '@angular/core';
import { Http } from '@angular/http';
import { LabComponent } from './lab/lab.component';

import { LabService } from './lab/lab.service';

@Component({

  selector: 'my-app',

  template: `
    <router-outlet></router-outlet>
  `,

  providers: [LabService]

})

export class AppComponent { 

  constructor() {
  }

  pageTitle: string = 'ABC';
}

添加模块 OphistoryModule 后我遇到的问题是错误消息

我的应用内＆＃39;不是一个已知元素：

但是当我为新添加的模块的选择器指定相同的名称时，它工作正常。以下是自定义模块和组件

ophistory.module

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser'
import { OphistoryComponent } from './ophistory.component'
import {CommonModule} from '@angular/common'
@NgModule({ 
imports: [RouterModule.forChild([
   {path: 'test',component:OphistoryComponent}
]),CommonModule],
  declarations:[OphistoryComponent]
})
export class OphistoryModule {}

ophistory.component

import { Component } from '@angular/core'
import { LabService } from '../lab/lab.service'

@Component({
  selector:'my-ap',
  templateUrl:'./ophistory.component.html'
})
export class OphistoryComponent {
  constructor (private _service:LabService){}
}

任何人都可以确认它是角度2中的错误还是您拥有的任何其他解决方案？
