当我使用 JIT 运行我的 Angular 2 应用程序时，一切正常。 但是在我切换到 AOT 之后，我的应用程序开始使用附加前缀(“/src/linker/ng_module_factory”)提取链接，例如:
JIT 拉取:http://localhost:8080/node_modules/@angular/core/bundles/core.umd.js
AOT 拉取:http://localhost:8080/node_modules/@angular/core/bundles/core.umd.js/src/linker/ng_module_factory
postfix /src/linker/ng_module_factory 来自哪里？
关于应用程序。我正在使用 Java 8 + Spring 4.3.2.RELEASE + Angular 2 + Tomcat 9.0.0.M6。

import { AppComponent } from './app.component';
@NgModule({

AppComponent
],
bootstrap: [ AppComponent ]
})
export class AppModule {}
JIT 配置 主.ts
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app.module';
platformBrowserDynamic().bootstrapModule(AppModule);
下一步是使用命令 tsc 进行编译，构建 war 并进行部署。
AOT 配置 主.ts
import { platformBrowser } from '@angular/platform-browser';
import { AppModuleNgFactory } from './app.module.ngfactory';
platformBrowser().bootstrapModuleFactory(AppModuleNgFactory);
下一步是安装编译器npm install @angular/compiler-cli，使用命令'./node_modules/.bin/ngc'编译，构建war并部署。
ngc 命令后，我得到文件 *.ngfactory.ts、*.ngfactory.js、*.metadata.json、*.shim.ts、*.shim.js
最佳答案
使用 angular2-webpack-starter 不用担心
关于Angular 2 AOT 不起作用。为什么 "platformBrowser().bootstrapModuleFactory"会拉取带有附加前缀 "/src/linker/ng_module_factory"的链接？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/40070930/
