尝试使用nestjs将一个服务注入另一个服务时出现问题

@Injectable()
export class ServiceA {
  constructor(private serviceB: ServiceB) {}
}

@Injectable()
export class ServiceB {}

@Injectable()
export class ServiceA {
  constructor(@Inject(forwardRef(() => ServiceB)) private serviceB: ServiceB) {}
}

@Injectable()
export class ServiceB {
  constructor(@Inject(forwardRef(() => ServiceA)) private serviceA: ServiceA) {}
}

@Module({
  imports: [ServiceB], // 导入需要注入的服务
  providers: [ServiceA],
})
export class AppModule {}

@Module({
  providers: [ServiceA, ServiceB], // 注册需要注入的服务
})
export class AppModule {}
