我想用这样的东西：

猫接口.ts

export interface ICats {
  meow(): void
}

猫服务.ts

@Injectable()
export class CatsService implements ICats {
  constructor()

  meow(): void {
    return;
  }
}

猫模块.ts

@Module({
  providers: [CatsService]
  exports: [CatsService]
})
export class CatsModule {}

动物.service.ts

@Injectable()
export class AnimalsService {
  constructor(@Inject('ICats') private readonly cats: ICats)

  test(): void {
    return this.cats.meow();
  }
}

动物模块.ts

@Module({
  imports: [CatsModule],
  providers: [AnimalsService],
  exports: [AnimalsService]
