我有一个项目，我使用媒体，CQRS和洋葱架构。

public class CreateOrderCommandHandler : IRequestHandler<CreateOrderCommand, CreatedOrderDto>
{
    private readonly IOrderRepository _orderRepository;
    private readonly IProductRepository _productRepository;
    private readonly IMapper _mapper;

    public CreateOrderCommandHandler(IOrderRepository orderRepository,IProductRepository 
                                     productRepository,  IMapper mapper)
    {
        _orderRepository = orderRepository;
        _productRepository = productRepository;
        _mapper = mapper;  
    }

    public async Task<CreatedOrderDto> Handle(CreateOrderCommand request, CancellationToken 
                                            cancellationToken)
    {
        // _orderRepository.Add(order);
        // _ productRepository.Update(product);
    }

}

CreateOrder命令是否应依赖于产品服务而不是产品资料档案库？
是否应在处理程序中使用存储库？
