求助channel和model不是一对一的关系么？ 什么时候会存在一个channel对应多个model的情况 因为我看Channel.hbm.xml的定义是 <class name="Channel" table="jc_channel" dynamic-update="true"> <br/> <meta attribute="sync-DAO">false</meta> <br/> <cache usage="read-write"/> <br/> <id name="id" type="java.lang.Integer" column="channel_id"><generator class="identity"/></id> <br/> <property name="path" column="channel_path" type="string" not-null="false" length="30"/> <br/> <property name="lft" column="lft" type="integer" not-null="true" length="10"/> <br/> <property name="rgt" column="rgt" type="integer" not-null="true" length="10"/> <br/> <property name="priority" column="priority" type="integer" not-null="true" length="10"/> <br/> <property name="hasContent" column="has_content" type="java.lang.Boolean" not-null="true"/> <br/> <property name="display" column="is_display" type="java.lang.Boolean" not-null="true"/> <br/> <one-to-one name="channelExt" class="ChannelExt" cascade="delete"/> <br/> <one-to-one name="channelCount" class="ChannelCount" cascade="delete"/> <br/> <many-to-one name="model" column="model_id" class="CmsModel" not-null="true"></many-to-one> <br/> <many-to-one name="parent" column="parent_id" class="Channel" not-null="false"></many-to-one> <br/> <many-to-one name="site" column="site_id" class="com.jeecms.core.entity.CmsSite" not-null="true"></many-to-one> <br/> <set name="child" inverse="true" cascade="delete" sort="com.jeecms.common.hibernate3.PriorityComparator"> <br/> <cache usage="read-write"/> <br/> <key column="parent_id"/> <br/> <one-to-many class="Channel"/> <br/> </set> <br/> <list name="channelModels" table="jc_channel_model"> <br/> <cache usage="read-write"/> <br/> <key column="channel_id"/> <br/> <list-index column="priority"/> <br/> <composite-element class="ChannelModel"> <br/> <property name="tplContent" column="tpl_content" type="string" length="100" not-null="true"/> <br/> <many-to-one name="model" column="model_id" class="CmsModel" not-null="false"></many-to-one> <br/> </composite-element> <br/> </list> channelModels 这里取的是一个LIST 谁能解释一下？

一个模型可以对应多个栏目，一个栏目对应只能对应一个模型

既然一个栏目只能对应一个模型
那Channel.hbm.xml为什么要将channelModels这个字段定义为一个LIST？？？
<list name="channelModels" table="jc_channel_model">
<cache usage="read-write"/>
<key column="channel_id"/>
<list-index column="priority"/>
<composite-element class="ChannelModel">
<property name="tplContent" column="tpl_content" type="string" length="100" not-null="true"/>
<many-to-one name="model" column="model_id" class="CmsModel" not-null="false"></many-to-one>
</composite-element>
</list>

抱歉，源码请自己研究

回复第4楼
呵呵，这是很明显的错误
