Room表和worker表

Room映射文件如下：

       <hibernate-mapping>

    <class name="com.data.Room" table="room" schema="dbo" catalog="xmgl"  dynamic-update="true" dynamic-insert="true">

        <id name="roomId" type="java.lang.Integer">

            <column name="room_id" />

            <generator class="identity" />

        </id>

        <property name="roomName" type="java.lang.String">

            <column name="room_name" length="10" />

        </property>

        <set name="workers" inverse="true" cascade="all">

            <key>

                <column name="worker_roomid" />

            </key>

            <one-to-many class="com.data.Worker" />

        </set>

    </class>

</hibernate-mapping>

 

 

Worker映射文件如下：
