这个是什么问题，在网上没找到相关的资料

映射文件没有问题，拿到其他项目测试正常

[MappingException: could not instantiate id generator for strategy 'native'] 

这句的问题吧 你研究研究

PS:觉得有用的话,楼主赏个分吧

你还是得看看你的id的类型...是不是int ,navtive的id策略,说明你的id由数据库生成,所以你在数据库的表里,把他设置成自增

象这样

<id name="LanguageID" column="LanguageID" unsaved-value="0" type="System.Int32">
<generator class="native"/>
</id>

[wazdoyang]

你的主键 ID 是自动增长列吗？

[Aleda]

不是

[Aleda]

顶上去

那你映射文件 貼出來 有嗎
