如何在私有构造函数中注入服务

Question

我通过拥有私有构造函数和返回对象实例返回对象 -

export class SingletonFactory {
  private static factoryInstance = new SingletonFactory();
  private constructor() {
  }
  public static getInstance() {
    return SingletonFactory.factoryInstance;
  }
}

我需要向该工厂注入依赖。我将代码更改为以下 -

@Inject('MyService')
export class SingletonFactory {
  private static factoryInstance = new SingletonFactory();
  private constructor(private myService : MyService) {
  }
  public static getInstance() {
    return SingletonFactory.factoryInstance;
  }
}

请建议，我如何在构造函数中注入对象创建的依赖关系？

注入您的组件。

import { Router } from  '@angular/router';
    import { FormBuilder, FormGroup, Validators} from '@angular/forms';
    import { Location } from '@angular/common';
    constructor(public location: Location,public fb:FormBuilder,public global_service:GlobalService,public router: Router) { 
      }
