public class RoomBooking : Entity, IBooking
{
    public virtual Client Client { get; set; }
    public virtual Address Address { get; set; }
    public virtual IList<BookingPeriod> BookingPeriods{get;set;}...


public class BookingPeriod : Entity
{
    public virtual IEnumerable<IBooking> Bookings { get; set; }
    public virtual DateTime StartTime { get; set; }
    public virtual DateTime EndTime { get; set; }...

对NHibernate来说,最好的方法是什么?我现在使用的是S#arp,它利用Fluent NHibernate的自动映射功能。这会导致 Bookings 属性,因为它试图引用未映射的类( IBooking ).

如果您使用的是fluent NHibernate,则可以这样做,它指定要将预订映射到的类名,而不是尝试映射到接口IBooking的Automapper:

 public class RoomBooking : Entity, IBooking
{
    public virtual Client Client { get; set; }
    public virtual Address Address { get; set; }
    public virtual IList<BookingPeriod> BookingPeriods { get; set; }

}

public class RoomBookingMap : EntityMap<RoomBooking>
{
    public RoomBookingMap()
    {
        Map(x => x.Client);
        Map(x => x.Address);
        HasManyToMany(x => x.BookingPeriods);
    }

}

public class BookingPeriod : Entity
{
    public virtual IEnumerable<IBooking> Bookings { get; set; }
    public virtual DateTime StartTime { get; set; }
    public virtual DateTime EndTime { get; set; }
}

public class BookingPeriodgMap : EntityMap<BookingPeriod>
{
    public BookingPeriodgMap()
    {
        Map(x => x.StartTime);
        Map(x => x.EndTime);
        HasManyToMany<RoomBooking>(x => x.Bookings);
    }

}
 public class EntityMap<T> : ClassMap<T> where T : Entity
    {
        public EntityMap()
        {
            Id(x => x.Id)
                .UnsavedValue(-1)
                .Column("id");

        }


    }
