注入DynamicComponentLoader错误 - Angular2

Question

我正在使用DynamicComponentLoader将组件动态加载到菜单栏中。

这是我的组件类的样子：

@Component({
  selector: 'create-submenu-component',
  templateUrl: 'common/create/create.component.html',
  styleUrls: ['common/create/create.component.css'],
  directives: [CreateAssetComponent]
})
export class CreateSubmenuComponent {
  public model: Model;

  constructor(private _modelService:ModelService, public http: Http) {
    this.model = this._modelService.getModel();
  }
}

动态组件创建方法：

constructor(public injector:Injector){}

loadCreateSubMenu(){
  this.dcl.loadAsRoot(CreateSubmenuComponent, '#Create', this.injector);
}

当我尝试加载包含服务的组件时，我收到以下错误：

Cannot resolve all parameters for 'CreateSubmenuComponent'(undefined, Http). Make sure that all the parameters are decorated with Inject or have valid type annotations and that 'CreateSubmenuComponent' is decorated with Injectable.

正在注入的服务显示为未定义。子菜单不依赖服务的组件可以正常加载。如何将服务注入动态创建的组件？
