Question

所以我正在处理错误：

行被另一个事务（或未保存的值）更新或删除映射不正确）： [Domain.Entities.General.Shipping＃0]

当用户想要在我的应用程序中更新他们的送货地址时。

控制器

var shippingToAdd = new Shipping
                {
                    UserId = newUserId,
                    FirstName = model.FirstName,
                    LastName = model.LastName,
                    Address = model.ShippingStreet,
                    SteApt = model.ShippingAptSte,
                    City = model.ShippingCity,
                    State = model.ShippingState,
                    Zip = model.ShippingZip,
                    Country = shippingCountryId,
                };
                UserManagerService.UpdateShipping(shippingToAdd);

UserManagerService

public static ISession Context { get; set; }

        public UserManagerService(ISession context)
        {
            Context = context;
        }

    public static int UpdateShipping(Shipping shipping )
    {
        using (ITransaction transaction = Context.BeginTransaction()) 
        {
            Context.Update(shipping);
            transaction.Commit();
            return 0; //Right Here is where StaleObjectStateException occurs
        }
    }

无论如何在Commit（）之前解除锁定？或者最新发布锁定的最佳方式是什么？

Answer 1

如果您尝试添加新对象，我不明白为什么要调用Update（）。你的意思是使用ISession.Save（）还是ISession.SaveOrUpdate（）？

StaleObjectStateException我正在更新刚刚创建的用户帐户
