NHibernate映射用于多接口

public interface ICategoryParent
{
    ICollection<Category> Categories { get; set; }
}

public interface IColorParent
{
    ICollection<Color> Colors { get; set; }
}

public class Category
{
    public string Name { get; set; }
    public ICategoryParent Parent { get; set; }
}

public class Color
{
    public string Hue { get; set; }
    public IColorParent Parent { get; set; }
}

public class ObjectA : ICategoryParent, IColorParent
{
    //[....] Some other properties
    ICollection<Category> Categories { get; set; }
    ICollection<Color> Colors { get; set; }
}

public class ObjectB : ICategoryParent, IColorParent
{
    //[....] Some other properties
    ICollection<Category> Categories { get; set; }
    ICollection<Color> Colors { get; set; }
}
