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?

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_factorypostfix /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。

应用程序组件.ts

import { Component } from '@angular/core';

@Component({
selector: 'my-app',
template: `
<h1>{{title}}</h1>
`,
styleUrls: ['app.component.css']
})
export class AppComponent{
title = 'Title';
}

应用程序模块.ts

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';

@NgModule({
imports: [
BrowserModule
],
declarations: [
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
