IndexOutOfRangeException在NHibernate的深处

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的内容深处得到以下错误:

执行System.IndexOutOfRangeException:此SqlParameterCollection的索引6无效,Count = 6.在System.Data.SqlClient.SqlParameterCollection.RangeCheck(Int32索引)的System.Data.SqlClient.SqlParameterCollection.GetParameter(Int32索引)处于System.Data.Common.DbParameterCollection.System.Collections.IList.get_Item(Int32 index)s:\NHibernate\NHibernate\src\NHibernate\Type\DateTimeType.cs(65,0):at NHibernate.Type.DateTimeType.Set(IDbCommand st,Object value,Int32 index)s:\ NHibernate\NHibernate\src\NHibernate\Type\NullableType.cs(180,0):at NHibernate.Type.NullableType.NullSafeSet(IDbCommand cmd,Object value,Int32 index)s:\ NHibernate\NHibernate\src\NHibernate\Type\NullableType.cs(139,0):在NHibernate.Type.NullableType.NullSafeSet(IDbCommand st,Object value,Int32 index,ISessionImplementor session)s:\ NHibernate\NHibernate\src\NHibernate\Type\ComponentType.cs(213,0):at NHibernate.Type.ComponentType.

现在有趣的是,如果我在SecurityMap中注释掉对Company或PrimaryListing的引用,我就不会收到错误.我评论出来并不重要.只有当我同时出现错误时才会发生错误.

当更新实际通过NHProf显示我这个更新:

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 */

我不确定为什么它会更新CompanyId和EndDate,但我怀疑它是相关的.

有谁有想法？非常感谢周围的工作.

Answer 1

是的,这是一个常见问题,您Column "EndDate"在映射定义中使用了两次(对于Company和PrimaryListing)并且不允许这样做.其中一个必须去,或者有一个额外的EndDate列(每个关联一个)

检查这个 nHibernate 2.0 - 映射复合id*和*多对一关系会导致"无效索引"错误
