<column name="gname" length="20" not-null="true"></column>
</property>
<property name="gdesc">
<column name="gdesc"></column>
</property>
<!-- 配置一对多关联关系 -->
<set name="students" table="student">
<key column="gid"></key>
<one-to-many class="com.wzl.entity.Student"/>
</set>
</class>
</hibernate-mapping>
hibernate.cfg.xml
<hibernate-configuration>

</property>
<property name="show_sql">true</property>
