Hibernate 映射文件报错！

Question

这是我配置的映射文件

<class name="entity.Backmoney" table="backmoney">
 <id name="code" type="java.lang.String">
  <column name="code" />
  <generator class="assigned" />
 </id>

----------------------------------------------------------------------------

我数据库这个表里面的主键是Varchar2类型的！ 我想自定义设置主键！

运行的时候出错了！

Exception in thread "main" org.hibernate.MappingException: Repeated column in mapping for entity: entity.Backmoney_detail column: code (should be mapped with insert="false" update="false")
