Question

我已将不断增长的ng2应用程序升级到RC5，并将所有组件/管道放入一个胖主模块中。为了对抗臃肿，我试图将我的应用程序分成单独的模块（同时着眼于最终进行延迟加载）。

这是我创建的子模块，其中包含一些通用组件：

MY-shared.module.ts

import { NgModule }      from "@angular/core";
import { BrowserModule } from "@angular/platform-browser";
import { FormsModule } from "@angular/forms";
import { provideForms, disableDeprecatedForms } from"@angular/forms";

import { TabBarWidgetComponent } from "./tabBarWidget/tabbar-widget.component";
import { MyDatepickerComponent } from "./mykDatePicker/my-datepicker.component";
import { CalendarSelectorComponent } from "./calendarSelector/calendar-selector.component";
import { AccordionTabComponent } from "./accordionTab/accordion-tab.component";


@NgModule({
  imports: [
      BrowserModule,
      FormsModule
  ],
  declarations: [
      TabBarWidgetComponent,
      MyDatepickerComponent,
      CalendarSelectorComponent,
      AccordionTabComponent

  ],
  providers: [
      provideForms(),
      disableDeprecatedForms()
  ]

})
export class MySharedModule { }

到目前为止一切顺利。现在我想在主app.module.ts中引用这个MySharedModule，我正在做这样的事情：

import { NgModule }      from "@angular/core";
import { BrowserModule } from "@angular/platform-browser";
import { FormsModule } from "@angular/forms";
import { HttpModule } from "@angular/http";

import { MySharedModule } from "./shared/my-shared.module";

import { Some1Component } from "./folder/some1.component";
import { Some2Component } from "./folder/some2.component";
import { Some3Component } from "./folder/some3.component";
import { Some4Component } from "./folder/some4.component";
import { Some5Component } from "./folder/some5.component";

import "rxjs/add/operator/map";
import "rxjs/add/operator/toPromise";

@NgModule({
  imports: [
    BrowserModule,
    FormsModule,
    HttpModule,
    MySharedModule
  ],
  declarations: [
    AppComponent,
     Some1Component,
     Some2Component,
     Some3Component,
     Some4Component,
     Some5Component,

  ],
  providers: [],
  bootstrap: [AppComponent],
  entryComponents: []

})
export class AppModule { }

问题是我收到以下错误（这表明app.module.ts中定义的应用程序无法识别子模块组件）：

无法绑定到“标签”，因为它不是“标签栏”的已知属性。 1.如果'tab-bar'是一个Angular组件并且它有'tabs'输入，那么请确认它是该模块的一部分。 2.如果'tab-bar'是Web组件，则将“CUSTOM_ELEMENTS_SCHEMA”添加到此组件的'@NgModule.schema'以禁止显示此消息。

谁能看到我做错了什么？

尝试在共享模块中添加exports部分。

import { NgModule }      from "@angular/core";
import { BrowserModule } from "@angular/platform-browser";
import { FormsModule } from "@angular/forms";
import { provideForms, disableDeprecatedForms } from"@angular/forms";

import { TabBarWidgetComponent } from "./tabBarWidget/tabbar-widget.component";
import { MyDatepickerComponent } from "./mykDatePicker/my-datepicker.component";
import { CalendarSelectorComponent } from "./calendarSelector/calendar-selector.component";
import { AccordionTabComponent } from "./accordionTab/accordion-tab.component";


@NgModule({
  imports: [
      BrowserModule,
      FormsModule
  ],
  exports: [
      TabBarWidgetComponent,
      MyDatepickerComponent,
      CalendarSelectorComponent,
      AccordionTabComponent
  ],
  declarations: [
      TabBarWidgetComponent,
      MyDatepickerComponent,
      CalendarSelectorComponent,
      AccordionTabComponent
  ],
  providers: [
      provideForms(),
      disableDeprecatedForms()
  ]

})
export class MySharedModule { }

尝试更改组件的顺序检查此link以获取更多详细信息

考虑你的程序中是否有五个组件，A B C D E.如果是示例组件A在其模板中使用组件B，组件B 在模板中使用了组件C，依此类推，然后是依赖项这些组分之间是A-> B，B-> C，C-> D，D-> E，E-> F.在这如果在声明中列出它们的正确顺序将是声明：[E，D，C，B，A]。
