c# - NHibernate 嵌套类映射问题

Question

我有以下类(class)。如何为 MainBranch.Id 列编写映射文档。我在数据库中没有分支表，只想将 branchId 用于 MAINBRANCHCODE。任何想法？

public class Bundle
        {
            public virtual Decimal Id { get; set; }       
            public virtual BundleEntranceInformation Information { get; set; } 
        }
    public class BundleEntranceInformation
        {
            public virtual Branch MainBranch { get; set; }      
        }
    public class Branch
        {
            public virtual short Id { get; set; }       
        }

我的映射文档:

<class name="PromissoryNotes.Server.Data.Bundle, PromissoryNotes.Server.Data" table="BUNDLE" lazy="true">
    <id name="Id" column="ID" type="Decimal">
      <generator class="increment" />
    </id>   
    <property name="Information.MainBranch.Id" column="MAINBRANCHCODE" type="short"></property>

  </class>

使用组件映射

<class name="BundleEntranceInformation">
  <component name="MainBranch">
    <property name="Id" column="MAINBRANCHCODE"/>
  </component>
</class>
