自关联：

 只对子类进行级联

 

<many-to-one name="parent"
   class="com.boco.bocotest.model.Department" column="parent_ID" />

  <set name="depchild" cascade="all"  lazy="false" inverse="false">
   <key>
    <column name="parent_ID"></column>
   </key>
   <one-to-many class="com.boco.bocotest.model.Department" />
  </set>
