Question

我在将NHibernate映射到从一个基类派生的许多类时遇到问题。我想对我的解决方案实施审核功能，并希望在一个带有ParentId列的表中包含AuditLog记录。

课程：

public class AuditableObject
{
   private Guid _ID;
   private IEnumerable<AuditLog> _AUDIT;

   public Guid Id { get => _ID; set => _ID = value; }
   public IEnumerable<AuditLog> AuditLogs {get => _AUDIT; set => _AUDIT = value; }
}

public class DerivedOne : AuditableObject
{
   ...
} 

public class DerivedTwo : AuditableObject
{
   ...
}

public class AuditLog
{
   private Guid _ID;
   private AuditableObject _PARENT;

   public Guid Id { get => _ID; set => _ID = value; }
   public AuditableObject Parent { get => _PARENT; set => _PARENT = value; }
}

映射：


public class DerivedOneMap : ClassMapping<DerivedOne>
{
   Id(d => d.Id, g => g.Generator(Generators.GuidComb));
   Bag(d => d.AuditLogs, map => map.Key(k => k.Column("Parent")), rel => rel.OneToMany());
}

public class DerivedTwoMap : ClassMapping<DerivedTwo>
{
   Id(d => d.Id, g => g.Generator(Generators.GuidComb));
   Bag(d => d.AuditLogs, map => map.Key(k => k.Column("Parent")), rel => rel.OneToMany());
}

public class AuditLog : ClassMapping<AuditLog>
{
   Id(al => al.Id, g => g.Generator(Generators.GuidComb));
   ManyToOne(al => al.Parent, map => map.Column("Id"));
}

当我尝试将任何AuditLog添加到AuditableObject的任何派生版本并将其保存到DB时，出现此错误：

An association from the table AuditLog refers to an unmapped class: AuditableObject

有什么想法我做错了吗？

Nhibernate映射到许多类
