NHibernate：使用流利的NHibernate处理中间表的最佳方法？

您将如何在Fluent NHibernate中映射以下内容

参见“18.3.客户/订单/产品”

---

以下解决方案使用与示例中的解决方案相同的方法，生成的XML与示例中的解决方案一样好。为了简洁起见，我省略了指定列名之类的内容

域：

public class Customer
{
    private ISet<Order> orders = new HashedSet<Order>();

    public long Id { get; set; }
    public string Name { get; set; }
    public ISet<Order> Orders
    {
        get { return orders; }
        private set { orders = value; }
    }
}

public class Order
{
    public long Id { get; set; }
    public DateTime Date { get; set; }
    public Customer Customer { get; set; }
    public IList<LineItem> LineItems { get; private set; }
}

public class LineItem
{
    public int Quantity { get; set; }
    public Product Product { get; set; }
}

public class Product
{
    public long Id { get; set; }
    public string SerialNumber { get; set; }
}

public class CustomerMap : ClassMap<Customer>
{
    public CustomerMap()
    {
        Id(x => x.Id)
            .GeneratedBy.Native();

        Map(x => x.Name);

        HasMany<Order>(x => x.Orders)
            .IsInverse()
            .AsSet();
    }
}

public class OrderMap : ClassMap<Order>
{
    public OrderMap()
    {
        Id(x => x.Id)
            .GeneratedBy.Native();

        Map(x => x.Date);

        References<Customer>(x => x.Customer);
        HasMany<LineItem>(x => x.LineItems)
            .Component(c =>
                {
                    c.Map(x => x.Quantity);
                    c.References<Product>(x => x.Product);
                }).AsList();
    }
}

public class ProductMap : ClassMap<Product>
{
    public ProductMap()
    {
        Id(x => x.Id)
            .GeneratedBy.Native();

        Map(x => x.SerialNumber);
    }
}
