org.hibernate.MappingException: Duplicate property mapping of version found

单看错误信息是提示有重复参数。。
看看是不是CountResultInfoData 中有重复的参数。
还有主键有没有定义。

@Id//定义主键
@GeneratedValue//主键生成策略

你继承了FrmData ，看不到此类代码，你可以自己检查下。追问

问题搞定了，就是因为继承了FrmData，而FrmData里面已经把一些公共的全部写了，所以就报错了，因为是公司的框架，刚进入公司，不明白！谢谢！

追答

解决了就好

参考技术A 嵌套异常org.hibernate.mappingexception：重复的属性映射版本中发现com.shinetecnology.cwa.entity.data.countresultinfodata追问

。。。
我当然知道去翻译一下了 ，主要是我里面没有重复的！全部找过了！

追答

web.xml中是不是配置有问题啊？你可以检查下

hibernate注解HQL 报错

@Entity(name="icertInfo") HQL  查询的时候 需要写Entry 的name值，要不然会报错 iCertInfo is not mapped

packagesToScan   ，配置错误 HQL 也会报错
