NHibernate存储过程映射复杂对象的属性

Question

我有一个SQL存储过程，我试图用来加载一组实体。我的实体看起来像这样

public class Person
{ 
       public virtual int Id {get;set;}
       public virtual string Name {get;set;}
       public virtual Colour FavoriteColour {get;set;}
}

public class Colour
{
       public virtual int Id {get;set;}
       public virtual string Name {get;set;}
}

我的存储过程或多或少看起来像这样：

Create Procedure getAllPersons
AS
     SELECT
            p.Id as PersonId,
            p.Name as PersonName,
            c.Id as ColourId,
            c.Name as ColourName
     FROM
            Person p JOIN Colour c
      p.ColourId = c.Id

我的映射看起来像这样

<class name="Person">
  <id name="Id">
    <generator class="native"/>
  </id>
  <property name="Name" />
  <many-to-one name="FavoriteColour" class="Foo, Colour" column="ColourId"/>
</class>

<sql-query name="getAllPersons">
    <return class="Person">
        <return-property name="Id" column="PersonId"/>
        <return-property name="Name" column="PersonName"/>
        <return-property name="FavoriteColour">
            <return-column name="ColourId"/>
        </return-property>
    </return>
    exec getAllPersons
</sql-query>

我想知道如何将我的proc的colourName列映射到Person实体上的FavoriteColour.Name属性，以便 Person上的FavoriteColour对象将填充其Id和Name属性。有什么想法吗？
