我决定把我学到的东西都压缩到一个文件里。 与RC5之前相比，这里有很多东西值得考虑。注意，这个源文件包括AppModule和AppComponent。

import {

export class DynamicComponentRenderer implements OnInit {

  factory: ModuleWithComponentFactories<DynamicModule>;

  constructor(private vcRef: ViewContainerRef, private compiler: Compiler) { }

  ngOnInit() {
    if (!this.factory) {
      const dynamicComponents = {
        sayName1: {comp: SayNameComponent, inputs: {name: 'Andrew Wiles'}},
        sayAge1: {comp: SayAgeComponent, inputs: {age: 30}},
        sayName2: {comp: SayNameComponent, inputs: {name: 'Richard Taylor'}},
        sayAge2: {comp: SayAgeComponent, inputs: {age: 25}}};
      this.compiler.compileModuleAndAllComponentsAsync(DynamicModule)
        .then((moduleWithComponentFactories: ModuleWithComponentFactories<DynamicModule>) => {
          this.factory = moduleWithComponentFactories;
          Object.keys(dynamicComponents).forEach(k => {
            this.add(dynamicComponents[k]);
          })
        });
    }
  }

  addNewName(value: string) {
    this.add({comp: SayNameComponent, inputs: {name: value}})
  }

  addNewAge(value: number) {
    this.add({comp: SayAgeComponent, inputs: {age: value}})
  }

  add(comp: any) {
    const compFactory = this.factory.componentFactories.find(x => x.componentType === comp.comp);
    // If we don't want to hold a reference to the component type, we can also say: const compFactory = this.factory.componentFactories.find(x => x.selector === 'my-component-selector');
    const injector = ReflectiveInjector.fromResolvedProviders([], this.vcRef.parentInjector);
    const cmpRef = this.vcRef.createComponent(compFactory, this.vcRef.length, injector, []);
    Object.keys(comp.inputs).forEach(i => cmpRef.instance[i] = comp.inputs[i]);
  }
}

@Component({

})
class SayNameComponent {
  @Input() public name: string;
};

@NgModule({
  imports: [BrowserModule],

})
class DynamicModule {}

@Component({
  selector: 'app-root',
  template: `
        <h3>{{message}}</h3>
        <app-dynamic #ad></app-dynamic>

    `,
})
export class AppComponent {
  message = 'this is app component';
  @ViewChild(DynamicComponentRenderer) dcr;

}

@NgModule({
  imports: [BrowserModule],
  declarations: [AppComponent, DynamicComponentRenderer],
  bootstrap: [AppComponent]
})
export class AppModule {}`

EDIT (26/08/2017): The solution below works well with Angular2 and 4. I've updated it to contain a template variable and click handler and tested it with Angular 4.3. For Angular4, ngComponentOutlet as described in Ophir's answer is a much better solution. But right now it does not support inputs & outputs yet. If [this PR](https://github.com/angular/angular/pull/15362] is accepted, it would be possible through the component instance returned by the create event. ng-dynamic-component may be the best and simplest solution altogether, but I haven't tested that yet.

@Long Field的答案是正确的!下面是另一个(同步)例子:

import {Compiler, Component, NgModule, OnInit, ViewChild,
  ViewContainerRef} from '@angular/core'
import {BrowserModule} from '@angular/platform-browser'

@Component({
  selector: 'my-app',
  template: `<h1>Dynamic template:</h1>
             <div #container></div>`
})
export class App implements OnInit {
  @ViewChild('container', { read: ViewContainerRef }) container: ViewContainerRef;

  constructor(private compiler: Compiler) {}

  ngOnInit() {
    this.addComponent(
      `<h4 (click)="increaseCounter()">
        Click to increase: {{counter}}
      `enter code here` </h4>`,
      {
        counter: 1,
        increaseCounter: function () {
          this.counter++;
        }
      }
    );
  }

  private addComponent(template: string, properties?: any = {}) {
    @Component({template})
    class TemplateComponent {}

    @NgModule({declarations: [TemplateComponent]})
    class TemplateModule {}

    const mod = this.compiler.compileModuleAndAllComponentsSync(TemplateModule);
    const factory = mod.componentFactories.find((comp) =>
      comp.componentType === TemplateComponent
    );
    const component = this.container.createComponent(factory);
    Object.assign(component.instance, properties);
    // If properties are changed at a later stage, the change detection
    // may need to be triggered manually:
    // component.changeDetectorRef.detectChanges();
  }
}

@NgModule({
  imports: [ BrowserModule ],
  declarations: [ App ],
  bootstrap: [ App ]
})
export class AppModule {}

我想在Radim的这篇非常出色的文章上添加一些细节。

我采用了这个解决方案并研究了一段时间，很快就遇到了一些限制。我只列出这些，然后给出答案。

首先，我无法渲染动态细节在一个 dynamic-detail(基本上是将动态ui嵌套在彼此内部)。 下一个问题是我想在里面渲染一个动态细节 解决方案中提供的部件之一。这是 初始解也是不可能的。 最后，它不可能在动态部分使用模板url，如字符串编辑器。

我在这篇文章的基础上提出了另一个问题，关于如何实现这些限制，可以在这里找到:

在angar2中递归动态模板编译

如果您遇到与我相同的问题，我将概述这些限制的答案，因为这使解决方案更加灵活。这将是了不起的有最初的活塞更新，以及。

为了在彼此内部嵌套dynamic-detail，你需要在type.builder.ts的import语句中添加DynamicModule.forRoot()

protected createComponentModule (componentType: any) {
    @NgModule({
    imports: [
        PartsModule, 
        DynamicModule.forRoot() //this line here
    ],
    declarations: [
        componentType
    ],
    })
    class RuntimeComponentModule
    {
    }
    // a module for just this Type
    return RuntimeComponentModule;
}

除此之外，在字符串编辑器或文本编辑器的一个部分中使用<dynamic-detail>是不可能的。

要启用它，您需要更改parts.module.ts和dynamic.module.ts

你需要在DYNAMIC_DIRECTIVES中添加DynamicDetail

export const DYNAMIC_DIRECTIVES = [
   forwardRef(() => StringEditor),
   forwardRef(() => TextEditor),
   DynamicDetail
];

同样在dynamic.module.ts中，你必须删除dynamicDetail，因为它们现在是部件的一部分

@NgModule({
   imports:      [ PartsModule ],
   exports:      [ PartsModule],
})

一个工作的修改活塞可以在这里找到:http://plnkr.co/edit/UYnQHF?p=preview(我没有解决这个问题，我只是信使:-D)

最后，不可能在动态组件上创建的部件中使用templateurls。解决方案(或变通方案)。我不确定这是一个angular错误还是框架的错误使用)是在构造函数中创建一个编译器，而不是注入它。

    private _compiler;

    constructor(protected compiler: RuntimeCompiler) {
        const compilerFactory : CompilerFactory =
        platformBrowserDynamic().injector.get(CompilerFactory);
        this._compiler = compilerFactory.createCompiler([]);
    }

然后使用_compiler进行编译，然后也启用templateUrls。

return new Promise((resolve) => {
        this._compiler
            .compileModuleAndAllComponentsAsync(module)
            .then((moduleWithFactories) =>
            {
                let _ = window["_"];
                factory = _.find(moduleWithFactories.componentFactories, { componentType: type });

                this._cacheOfFactories[template] = factory;

                resolve(factory);
            });
    });

希望这能帮助到其他人!

对于这种特殊情况，使用指令动态创建组件将是更好的选择。 例子:

在您想要创建组件的HTML中

<ng-container dynamicComponentDirective [someConfig]="someConfig"></ng-container>

我将以以下方式处理和设计指令。

const components: {[type: string]: Type<YourConfig>} = {
    text : TextEditorComponent,
    numeric: NumericComponent,
    string: StringEditorComponent,
    date: DateComponent,
    ........
    .........
};

@Directive({
    selector: '[dynamicComponentDirective]'
})
export class DynamicComponentDirective implements YourConfig, OnChanges, OnInit {
    @Input() yourConfig: Define your config here //;
    component: ComponentRef<YourConfig>;

    constructor(
        private resolver: ComponentFactoryResolver,
        private container: ViewContainerRef
    ) {}

    ngOnChanges() {
        if (this.component) {
            this.component.instance.config = this.config;
            // config is your config, what evermeta data you want to pass to the component created.
        }
    }

    ngOnInit() {
        if (!components[this.config.type]) {
            const supportedTypes = Object.keys(components).join(', ');
            console.error(`Trying to use an unsupported type ${this.config.type} Supported types: ${supportedTypes}`);
        }

        const component = this.resolver.resolveComponentFactory<yourConfig>(components[this.config.type]);
        this.component = this.container.createComponent(component);
        this.component.instance.config = this.config;
    }
}

所以在你的组件中，文本，字符串，日期，任何你在HTML中传递的ng-container元素的配置都是可用的。

配置yourConfig可以是相同的，并定义您的元数据。

根据您的配置或输入类型，该指令应相应执行，并从受支持的类型中呈现适当的组件。如果不是，它将记录一个错误。

好消息!看起来@angular/cdk包现在对门户提供了一流的支持!

在撰写本文时，我并没有发现上面的官方文档有什么特别的帮助(特别是在向动态组件发送数据和从动态组件接收事件方面)。总之，你需要:

步骤1)更新AppModule

从@angular/cdk/portal包中导入PortalModule，在entryComponents中注册你的动态组件

@NgModule({
  declarations: [ ..., AppComponent, MyDynamicComponent, ... ]
  imports:      [ ..., PortalModule, ... ],
  entryComponents: [ ..., MyDynamicComponent, ... ]
})
export class AppModule { }

步骤2。选项A:如果你不需要向动态组件传递数据和从动态组件接收事件:

@Component({
  selector: 'my-app',
  template: `
    <button (click)="onClickAddChild()">Click to add child component</button>
    <ng-template [cdkPortalOutlet]="myPortal"></ng-template>
  `
})
export class AppComponent  {
  myPortal: ComponentPortal<any>;
  onClickAddChild() {
    this.myPortal = new ComponentPortal(MyDynamicComponent);
  }
}

@Component({
  selector: 'app-child',
  template: `<p>I am a child.</p>`
})
export class MyDynamicComponent{
}

看看它的实际应用

步骤2。选项B:如果你确实需要向动态组件传递数据并从动态组件接收事件:

// A bit of boilerplate here. Recommend putting this function in a utils 
// file in order to keep your component code a little cleaner.
function createDomPortalHost(elRef: ElementRef, injector: Injector) {
  return new DomPortalHost(
    elRef.nativeElement,
    injector.get(ComponentFactoryResolver),
    injector.get(ApplicationRef),
    injector
  );
}

@Component({
  selector: 'my-app',
  template: `
    <button (click)="onClickAddChild()">Click to add random child component</button>
    <div #portalHost></div>
  `
})
export class AppComponent {

  portalHost: DomPortalHost;
  @ViewChild('portalHost') elRef: ElementRef;

  constructor(readonly injector: Injector) {
  }

  ngOnInit() {
    this.portalHost = createDomPortalHost(this.elRef, this.injector);
  }

  onClickAddChild() {
    const myPortal = new ComponentPortal(MyDynamicComponent);
    const componentRef = this.portalHost.attach(myPortal);
    setTimeout(() => componentRef.instance.myInput 
      = '> This is data passed from AppComponent <', 1000);
    // ... if we had an output called 'myOutput' in a child component, 
    // this is how we would receive events...
    // this.componentRef.instance.myOutput.subscribe(() => ...);
  }
}

@Component({
  selector: 'app-child',
  template: `<p>I am a child. <strong>{{myInput}}</strong></p>`
})
export class MyDynamicComponent {
  @Input() myInput = '';
}
