<property name="award" column="isAward"/>
<property name="frozen" column="isFrozen"/>
<property name="typeNo" column="KTTypeNo"/>
<property name="description" column="Description"/>
<property name="status" column="Status"/>
</class>
</hibernate-mapping>我怎么记得说不要写column,会自动查找相关字段，也许是要属性名与字段名？是不是这个原因？
汗啊……
