Question

我有以下表结构：

ADVERTITEMBUY    |  ADVERTITEMSELL 
Id (PK)          |  Id (PK)
Title            |  Title
...              |  ...
-------------------------------------
BIDITEMBUY            | BIDITEMSELL
AdvertItemBuy (PK/FK) | AdvertItemSell (PK/FK)
...                   | ...

以编程方式，我正在做这个类结构：

public abstract class Advert : BaseEntity {
    public Guid Id { get; set; }
    public string Title { get; set; }
    ...
}

public class AdvertItemBuy : Advert {
   ...
}

public class AdvertItemSell : Advert {
   ...
}

-------------------------------------------------------------

public abstract class Bid : BaseEntity {
    public Advert Advert { get; set; }
    ...
}

public class BidItemBuy : Bid {
    ...
}
public class BidItemSell : Bid {
    ...
}

当我去Fluent NHibernate绘制这些课程时，我是这样做的：

public class BaseMapping<T> : ClassMap<T> where T : BaseEntity {
    public BaseMapping(string table, bool cacheEntities = false) {
        Schema("dbo");
        Table(string.Format("[{0}]", table));

        if (cacheEntities) {
            Cache.ReadWrite();
        }
    }
}

public class AdvertMapping<T> : BaseMapping<T> where T : Advert {
    public AdvertMapping(string tableName) : base(tableName) {
        Id(advert => advert.Id).GeneratedBy.Guid();
    }
}

public class AdvertItemBuyMapping: AdvertMapping<AdvertItemBuy> {
    public AdvertItemBuyMapping() : base("AdvertItemBuy") { }
}

public class BidMapping<T> : BaseMapping<T> where T : Bid {
    public BidMapping(string tableName, string advertTable) : base(tableName) {
        CompositeKey()
            .KeyReference(bid => bid.Advert, advertTable);
    }
}

public class BidItemBuyMapping : BidMapping<BidItemBuy> {
    public BidItemBuyMapping() : base("BidItemBuy", "AdvertItemBuy") { }
}

好的，我认为映射是正确的。当我尝试创建一个新的会话工厂时，NHibernate给了我以下错误：

{"An association from the table [BidItemBuy] refers to an unmapped class: SYB.Engine.Entities.Advert"}

我在这方面做错了什么？

谢谢大家！
