将fluent nhibernate中的子对象映射到只读视图

既然我正在实现一个只读UI,那么如何为它创建类映射呢 Shop

public class Shop {
    public int Id { get; set; }
    public City City { get; set; }
}

public class City {
    public string Name { get; set; }
    public string CountryCode { get; set; }
}

public sealed class ShopMap : ClassMap<Shop> {
    public ShopMap()
    {
        Table("Shop");
        Id(x => x.Id, "ShopId");
        Map(x => x.City.Name, "CityName");
        Map(x => x.City.CountryCode, "CountryCode");
    }
}

fluent会自动实例化Shop.City吗?
