StaleObjectStateException我在更新让刚创建

Question

让我处理错误的用户帐户：

Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [Domain.Entities.General.Shipping#0]

当用户想在我的应用程序来更新他们的送货地址

。

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 
     } 
    } 

反正是有解除提交权利之前锁（）？或者什么是一般释放锁的最佳方式？

我不明白为什么你调用Update（），如果你想添加一个新的对象。你的意思是使用ISession.Save（）或ISession.SaveOrUpdate（）吗？
