组件集合映射NHibernate的3.2 [英] component collection mapping NHibernate 3.2

问题描述

我有一个客户有地址：

 公共类客户
{
   公众诠释编号{获得;组; }
   公共字符串名称{;组; }
   公众的ICollection＆LT;地址＆gt;地址{获得;私定; }
}

公共类地址
{
   公共字符串市{获得;组; }
   公共字符串国家{获得;组; }
   公共字符串StreetName {获得;组; }
   公共字符串邮编code {获得;组; }
}
 

我想这个映射到NHibernate的3.2。它具有流畅的界面，但不完全一样知名的连贯NHibernate。 我知道，我必须用袋，也许元素？或组件？ 因此，它应该是这样的：

 袋（
   属性=＆GT; property.Addresses，
   collectionMapping =＆GT; {} //重要的是现在没有
   映射=＆GT; //我应该用什么在这里，怎么样？
  ）;
 

感谢。

解决方案

 公共类CustomerMap：ClassMapping＆LT;客户＆GT;
{
    公共CustomerMap（）
    {
        ID（X =＆GT; x.ID，地图=＆GT; map.Generator（Generators.HighLow，
                      GMAP =＆GT; gmap.Params（新{max_low = 100}）））;
        物业（X =＆GT; x.Name，
                      地图=＆GT; {map.Le​​ngth（150）; map.NotNullable（真正的）; }）;
        袋（X =＆GT; x.Addresses，
           collectionMapping =＆GT;
           {
               collectionMapping.Table（CustomerAddresses）;
               collectionMapping.Cascade（Cascade.All）;
               collectionMapping.Key（K =＆GT; k.Column（客户ID））;
           }）;
    }
}

I have a Customer which has Addresses:

public class Customer
{
   public int Id { get; set; }
   public string Name { get; set; }
   public ICollection<Address> Addresses { get; private set; }
}

public class Address 
{
   public string City { get; set; }
   public string Country { get; set; }
   public string StreetName { get; set; }
   public string ZipCode { get; set; }
}

I want to map this to NHibernate 3.2. which has fluent interface, but not exactly the same as well-known Fluent NHibernate. I know that I have to use Bag, and maybe Element? Or component? So it should be something like this:

Bag( 
   property => property.Addresses,
   collectionMapping => {}, // not important now
   mapping => // and what should I use here, and how?
  );

Thanks.

解决方案

public class CustomerMap : ClassMapping<Customer>
{
    public CustomerMap()
    {
        Id(x => x.ID, map => map.Generator(Generators.HighLow,
                      gmap => gmap.Params(new {max_low = 100})));
        Property(x => x.Name,
                      map => { map.Length(150); map.NotNullable(true); });
        Bag(x => x.Addresses,
           collectionMapping =>
           {
               collectionMapping.Table("CustomerAddresses");
               collectionMapping.Cascade(Cascade.All);
               collectionMapping.Key(k => k.Column("CustomerId"));
           });
    }
}
