具有复合主键/外键的流畅Nhibernate每实体表映射

Question

In .hbm.xml the mapping I am after would look as follows - any idea how I can reproduce this in Fluent NHibernate...?

    <class name="Dinosaur" table="Dinosaur" >
    <composite-id>
        <key-property name="Id" column="Id"/>
        <key-property name="Period" column="Period"/>
    </composite-id>
    <property name="DinosaurType" column="DinosaurType"  /> 
<joined-subclass name="Tyranosaur" table="Tyranosaur">
    <key>
        <column name="DinosaurId"/>
        <column name="DinosaurPeriod"/>
    </key>
    <property name="NumberOfTeeth">
        <column name="NumberOfTeeth">
        </column>
    </property>
</joined-subclass>

At the moment I have

public class DinosaurMap : ClassMap<Dinosaur>
{
    public DinosaurMap()
    {
    Table("Dinosaur");
    CompositeId()
        .KeyProperty(x => x.Id, "Id")
        .KeyProperty(x => x.Period, "Period")
    ;
    Map(x=>x.DinosaurType)
    ;
    }
}
public class TyranosaurMap : SubclassMap<Tyranosaur>
{
    public TyranosaurMap() 
    {
        Map(x=>x.NumberOfTeeth);
    }
}

but I can't figure out how, in the Tyranosaur SubclassMap, to specify the composite key. An issue on the NHibernate issue tracker suggest that this has been fixed in the 1.0 RTM build (I am using 1.0.0.593)

找到了答案-您需要多次调用.KeyColumn方法以添加列-也许.AddKeyColumn会是一个更好的名称...？
