我正在研究 Angular2。我们知道我们需要 在主模块中配置所有providers, components, 。services可能是我们有大量components并手动配置它的情况。例如，考虑以下module

 import { NgModule } from '@angular/core';
 import { FormsModule } from '@angular/forms';
 import { BrowserModule } from '@angular/platform-browser';
 import { HttpModule } from '@angular/http';
 import { AppComponent } from './app.component';
 import { GoogleSigninComponent } from ./auth/google.login.component';
 import { ApiEndpoints } from './api.endpoints';
 // Providers
 import { AuthService } from './auth/auth.service';
 import { AppRoutingModule } from './route';
 import { ExpenseComponent } from './expense/expense.component';
 import { ExpenseService } from './expense/expense.service';

 import { GroupService } from './group/group.service';
 import {GroupUserService} from './group/group-user.service';
 import {MainGroupComponent, SaveGroupComponent, GroupListComponent } from './group/group.components';
 import {GroupUsersComponent,AddGroupUserComponent} from './group/group-  user.component';
 import {HelperService } from './helper.service';
 import {SearchUserComponent} from './user/users.component';
 import {UserService} from './user/users.service';


@NgModule({
  imports: [BrowserModule, HttpModule, BrowserModule, AppRoutingModule, FormsModule],
  declarations: [AppComponent, GoogleSigninComponent,
  ExpenseComponent, SaveGroupComponent, GroupListComponent, GroupUsersComponent,
MainGroupComponent,AddGroupUserComponent,SearchUserComponent],
 bootstrap: [AppComponent],
 providers: [AuthService, ApiEndpoints, ExpenseService,
 GroupService,GroupUserService,HelperService,UserService]
  })

我需要在routes某种程度上配置相同cubersome 的内容 配置大量组件而无需大量复制粘贴的正确方法是什么？

另外，我相信应该有多个模块。您有什么建议或正确的做法？

对于服务，创建一个单独的 shared.ts 文件并导入和导出所有服务。因此，为每个文件创建一个像这样的 .ts 文件例如参见下面的代码

import { GroupService } from './group/group.service';
import {GroupUserService} from './group/group-user.service';

const SHARED_PROVIDERS: any[] = [
  GroupService ,
  GroupUserService
];

    export{
    Shared_Providers,
    GroupService ,
    GroupUserService

    }
