NHibernate一对一映射

非主键字段与主键字段的关联，在类中实现了一对一的单向映射。订单充值业务。显然，一单位可以有多个充值信息。通过表 Deposit里面的CompanyId字段关联表Company主键Id字段。

订单信息

    [Serializable]
    public class DepositInfo
    {
        /// <summary>
        /// 商户订单号
        /// </summary>
        public virtual string TradeNo        {get;set;}
        /// <summary>
        /// 商家Id
        /// </summary>
        public virtual int CompanyId        {get;set;} 
        public virtual Company CompanyInfo { get; set; }  
    }

映射文件

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2">
    <class name="Model.DepositInfo, Model " table="dbo.Deposit">
        <id name="Id" type="Int32" unsaved-value="http://www.cnblogs.com/lucika/p/0">
            <column name="Id" length="4" sql-type="int" not-null="true" unique="true"/>
            <generator class="native" />
        </id>
        <property name="TradeNo" type="string"/>
        <property name="CompanyId" column="CompanyId" type="int"  />
        <many-to-one name="CompanyInfo" fetch="join" column="CompanyId" not-found="ignore"></many-to-one>
     </class>
</hibernate-mapping>

商家信息

    public class Company 
    {
        public virtual int Id {get;set;}
　　 　　/// <summary>
        /// 厂家名称
        /// </summary>
        public virtual string Name {get;set;}
    }
