Typescript:如何重置从DI注入的服务的属性值

import { Injectable } from '@nestjs/common';
import { OtherService } from './other.service';

@Injectable()
export class MyService {
  constructor(private readonly otherService: OtherService) {}

  // ...
}

import { Injectable, Injector } from '@nestjs/common';
import { MyService } from './my.service';

@Injectable()
export class AnotherService {
  constructor(private readonly injector: Injector) {}

  resetMyService() {
    const myService = this.injector.get(MyService);
    // 重置属性值
    myService.property = null;
  }
}

import { Controller, Get } from '@nestjs/common';
import { AnotherService } from './another.service';

@Controller()
export class AppController {
  constructor(private readonly anotherService: AnotherService) {}

  @Get()
  resetService() {
    this.anotherService.resetMyService();
    return 'Service reset';
  }
}
