一个既有继承关系，又有component的映射文件的示例

ProducedWare映射表productioninfo,然后其中有一个叫ProductionInfo得组件
<class name="Ware" table="ware">
<id name="id" type="string">
<column name="ID" length="64" />
<generator class="assigned" />
</id>

<property name="name" type="string">
<column name="NAME" length="100" />
</property>

<joined-subclass name="ProducedWare" table="productioninfo">

<key column="ID" />

<component name="productionInfo" class="ProductionInfo">

<many-to-one name="wareGroup" class="WareGroup" fetch="select">
<column name="WAREGROUPID" length="64" />
</many-to-one>

<set name="factories" table="productiondetail" lazy="false">
<key column="PRODUCEDWAREID" />
<many-to-many class="Factory" column="FACTORYID" />
</set>

</component>

</joined-subclass>
</class>
