我有一个angular2组件,我想在多个模块之间共享。
所以我写了下面的sharedModule,
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import {GenericComponent} from './generic/generic.component';
@NgModule({
imports: [ BrowserModule ],
declarations: [ GenericComponent ],
exports: [ GenericComponent ]
})
export class SharedModule { }
然后我将这个sharedModule添加到多个模块中,如下所示:
app.module.ts
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import {SharedModule} from './shared.module';
import { AppComponent } from './app.component';
@NgModule({
imports: [ BrowserModule,SharedModule ],
declarations: [ AppComponent ],
exports: [ AppComponent ],
bootstrap: [AppComponent]
})
export class AppModule { }
我同样将sharedModule添加到generic.module.ts,
generic.module.ts
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import {SharedModule} from './shared.module';
@NgModule({
imports: [ BrowserModule,SharedModule ],
declarations: [ //.. here I have added all the components that generic uses ]
})
export class GenericModule { }
但是当我尝试在generic.module.ts的组件中使用泛型组件时,我遇到了以下错误
模块'GenericModule'
导入的意外值'undefined'

这是我的应用程序使用共享模块的代码:
应用模块:
String yourFilePath = context.getFilesDir() + "/" + "hello.txt";
File file = new File( yourFilePath );
if(file.exists())
{
}
家庭模块:
import { AboutModule } from './about/about.module';
import { SharedModule } from './shared/shared.module';
import { Menubar, MenuItem } from 'primeng/primeng';
@NgModule({
imports: [ BrowserModule, RouterModule.forRoot(appRoutes), SharedModule.forRoot(),
HomeModule ],
declarations: [ AppComponent ],
bootstrap: [ AppComponent ],
providers: [ appRoutingProviders ]
})
export class AppModule {}
共享模块:
import { SharedModule } from '../shared/shared.module';
import {routing} from './home.routing'
@NgModule({
imports: [ SharedModule, routing],
declarations: [ HomeComponent, LoginComponent, RegisterComponent, VerifyComponent,
VerifyEmailComponent, ForgotComponent, ForgotVerifyComponent,
ChangeComponent, ChallengeComponent, LogoutComponent ],
bootstrap: [ HomeComponent ],
providers: [ ]
})
export class HomeModule {}
我的应用程序中有20多个模块,我在整个地方使用共享模块。这很好用。希望它有所帮助。

您无法在featureModule中使用 BroswerModule 。因此,请确保使用 CommonModule ,而不是使用 BrowswerModule 。
import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import {SharedModule} from './shared.module';
@NgModule({
imports: [ CommonModule ,SharedModule ],
declarations: [ //.. here I have added all the components that generic uses ],
exports: [ CommonModule]
})
export class GenericModule { }
