NHibernate中对于多字段主键的Maping

NHibernate中对于多字段主键的Maping:

以下代码通过测试的

SumupCarte.hbm.xml:

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.0">
  <class name="Cash.Domain.SumupCarte, Cash.Domain" table="sumup_carte">
        <composite-id >
          <key-property name="Sid">
            <column name="sid"  sql-type="decimal" length="18" not-null="true"/>
          </key-property>
          <key-property name="Cid">
            <column name="cid" sql-type="decimal" length="18" not-null="true" />
          </key-property>
          <key-property name="IsCountermand">
            <column name="IsCountermand" sql-type="tinyint"  length="1" not-null="true" />
          </key-property>
        </composite-id>
  </class>
</hibernate-mapping>
