Angular自定义模块以及配置路由实现模块懒加载

ng g module module/user --routing
ng g module module/article --routing 
ng g module module/product --routing

ng g component module/user
ng g component module/user/components/profile 
ng g component module/user/components/order
ng g component module/article
ng g component module/article/components/articlelist 
ng g component module/article/components/info
ng g component module/product
ng g component module/product/components/plist
ng g component module/product/components/pinfo

import { AppComponent } from './app.component';


//上百个组件 会导致页面加载比较慢 所以要模块化
//引入自定义模块
import { UserModule } from './module/user/user.module';
import { ProductModule } from './module/product/product.module';
import { ArticleModule } from './module/article/article.module';
