无主键的Hibernate配置

Hibernate mapping 文件中必须有id或composite-id字段，若表没有主键，需要把所有字段定义成复合主键

 

< hibernate-mapping >

    < class name = "com.cqgl.po.SaI18nLimitRulesPO" table = "SA_I18N_LIMIT_RULES" >

     < composite-id >

           < key-property name = "aircompanyCode" type = "java.lang.String" >

                < column name = "AIRCOMPANY_CODE" />

           </ key-property >

          

           < key-property name = "aircompanyName" type = "java.lang.String" >

                < column name = "AIRCOMPANY_NAME" />

          </ key-property >

           

           ......

        </ composite-id >    

    </ class >

</ hibernate-mapping >
