à實體層映射：

     hibernate-mapping package="org.lxh.hibernate">

       <class name="Person" table="PERSON">

              <id name="id" column="ID" type="int">

                     <generator class="assigned" />

              </id>

              <component name="name" class="org.lxh.hibernate.Name">

                     <property name="firstname" column="FIRSTNAME" type="string" not-null="true" />

                     <property name="lastname" column="LASTNAME" type="string" not-null="true" />

              </component>

              <component name="contact" class="org.lxh.hibernate.Contact">

                     <property name="address" column="ADDRESS" type="string" not-null="true" />

                     <property name="zipcode" column="ZIPCODE" type="string" not-null="true" />

                     <property name="tel" column="TEL" type="string" />

              </component>

       </class>

</hibernate-mapping>
