nhibernate - IndexOutOfRangeException 深入 NHibernate

Question

我有以下映射:

public class SecurityMap : ClassMap<Security>
    {
        public SecurityMap()
        {
            Table("Security");
            CompositeId().KeyProperty(k => k.Id, "SecurityId").KeyProperty(k => k.EndDate);
            Map(x => x.LastUpdateUser);
            References(x => x.Company).Columns("CompanyId", "EndDate");
            References(x => x.PrimaryListing).Columns("PrimaryListingId", "EndDate");
         }
    }

public class ListingMap : ClassMap<Listing>
    {
        public ListingMap()
        {
            Table("Listing");
            CompositeId().KeyProperty(k => k.Id, "ListingID").KeyProperty(k => k.EndDate);
            References(x => x.Security).Columns("SecurityId","EndDate");
        }
    }

 public class CompanyMap : ClassMap<Company>
    {
        public CompanyMap()
        {
            Table("Company");
            CompositeId().KeyProperty(k => k.Id, "CompanyID").KeyProperty(k => k.EndDate);
            HasMany(x => x.Securities).KeyColumns.Add("CompanyId", "EndDate");
        }       
    }

当我尝试运行此测试时:

[Test]
public void can_update_a_security()
{
    var repo = IoC.Resolve<ISecurityRepository>();
    int someSecurity = 1;
    using (var work = IoC.Resolve<IUnitOfWorkManager>().Current)
    {
        Security security = repo.Get(someSecurity);
        security.ShouldNotBeNull();
        security.LastUpdateUser = "Dirk Diggler" + DateTime.Now.Ticks;
        repo.Save(security);
        work.Commit();
    }
}

我在 NHibernate 的内部深处收到以下错误:

现在有趣的是，如果我在 SecurityMap 中注释掉对 Company 或 PrimaryListing 的引用，我不会收到错误消息。我注释掉哪个似乎无关紧要。只有当我同时拥有两者时才会发生错误。

当更新实际通过 NHProf 时，会向我显示此更新:

UPDATE Security
SET    LastUpdateUser = '2010-02-19T08:09:24.00' /* @p0 */,
       CompanyId = 54199 /* @p1 */,
       EndDate = '9999-12-31T00:00:00.00' /* @p2 */
WHERE  SecurityId = 1 /* @p3 */
       AND EndDate = '9999-12-31T00:00:00.00' /* @p4 */

我不确定它为什么要更新 CompanyId 和 EndDate，但我怀疑它是相关的。

有人有想法吗？解决方法将不胜感激。

Answer 1

是的，这是一个常见问题，您正在使用 Column "EndDate"在您的映射定义中出现两次(对于 Company 和 PrimaryListing)，这是不允许的。其中一个必须去，或者有一个额外的 EndDate 列(每个关联一个)
