Question

我有一个类，我想使用Fluent NHibernate定义一个唯一的键。我想我已经正确完成了这个，但是我的单位测试中，我保存了两个具有相同字段值的对象，保存了两个项目而没有错误。这就是我所拥有的：

映射覆盖：

public class ItemOverride : IAutoMappingOverride<Item>
{
    #region IAutoMappingOverride<Item> Members

    public void Override(AutoMapping<Item> mapping)
    {
        mapping.Map(t => t.Prompt).UniqueKey("UIX_Item_Prompt").Not.Nullable();
    }

    #endregion
}

单元测试

[Test]
public void CannotSaveDuplicateItemPrompt()
{
    ServiceLocatorInitializer.Init();
    IItemManagementService itemManagementService = new ItemManagementService(repository);
    Item first = ItemInstanceFactory.CreateValidTransientItem();
    first.Prompt = "Duplicate";
    itemManagementService.SaveOrUpdate(first);
    Item second = ItemInstanceFactory.CreateValidTransientItem();
    second.Prompt = "Duplicate";

    ActionConfirmation confirm = itemManagementService.SaveOrUpdate(second);

    Assert.IsFalse(confirm.WasSuccessful);
    Assert.AreEqual(confirm.Message, "");
}

好的，如果我将两个保存包装在一个事务中，它就可以工作。这是新的单元测试：

    [Test]
    [ExpectedException(typeof(GenericADOException))]
    public void CannotSaveDuplicateItemPrompt()
    {
        ServiceLocatorInitializer.Init();
        IItemManagementService itemManagementService = new ItemManagementService(repository);

        NHibernateSession.Current.BeginTransaction();

        Item first = ItemInstanceFactory.CreateValidTransientItem();
        first.Prompt = "Duplicate";
        itemManagementService.SaveOrUpdate(first);
        Item second = ItemInstanceFactory.CreateValidTransientItem();
        second.Prompt = "Duplicate";

        ActionConfirmation confirm = itemManagementService.SaveOrUpdate(second);
        NHibernateSession.Current.Transaction.Commit();
    }

NHibernate UniqueKey没有被强制执行
