Nhibernate拦截器未获取基类的属性

Question

I'm converting from Fluent to Loquacious, and I've run in to an issue where my interceptors are not getting all the fields like I think they should. If I look at the OnSave function

public override Boolean OnSave(Object entity, Object id, Object[] state,
        String[] propertyNames, IType[] types)

and take a look at the propertyNames the only items in there are the items that were explicitly mapped in the mapping file (in the example this would just be ID, Start, and End).

In my case though I have a base class which isn't mapped at all. Instead it's just contains properties that get filled out by the interceptors. This used to work in Fluent Nhibernate, but now that I've moved to Nhibernate 3.3 I can't get it to work anymore.

My classes/mapping look something like this

public class BaseAuditEntity
{
  public virtual int ModifiedByUserID { get; set; }
  public virtual DateTime LastModifiedTime { get; set; }
}

public class Foo : BaseAuditEntity
{
  public virtual int ID { get; protected internal set; }
  public virtual DateTime Start { get; protected internal set; }
  public virtual DateTime End { get; protected internal set; }
}

public class FooMap: ClassMapping<Foo>
{
  Id(x => x.ID, m => m.column("fooID"));
  Property(x => x.Start, m => m.column("start"));
  Property(x => x.End, m => m.column("end"));
}

Any ideas of how to get this work? I don't want to have to map this every class, and I didn't think I needed to map the BaseAuditEntity, at least with Fluent it wasn't needed.

Answer 1

you could make a base mapping class

public class BaseAuditEntityMapping<T> : ClassMapping<T> where T: BaseAuditEntity
{
    ManyToOne(x => x.ModifiedByUser);
    Property(x => x.LastModifiedTime);
}

public class FooMap: BaseAuditEntityMapping<Foo>
