请问一下，这个错误是什么原因？我创建的扩展的实体如下：

#2

后面有各个属性的 getter 和 setter 吗？

#3

注意下这个错误信息：

extGroupSupervisor的setter/getter方法，注意大小写，这块好像卡的严。 比方说属性abcDef的方法必须是setAbcDef 这样。

写了，检查了一下没有问题呀：

看上去没问题，你运行一下试试。

错误如下：

有这个错：

你看看这个帖子，是否有帮助：

我试了上面的方法，还是不行，这个错误主要是由于我扩展了访问组和用户两个模块产生的，而这两个模块在我自己的project里一点问题都没有，但将扩展的实体及界面文件放到别的project里，并将相关class写到persistence文件就报这个错误，目前换成默认的数据库，还是报错：

你需要分析一下错误原因，也许虽然出错，但是错误类型不一样了。
另外，直接将实体文件拷贝到别的项目，需要修改package、@Entity 注解名、@Table 注解的表名、persistence.xml，如果有视图，还要修改views.xml。界面拷贝需要修改xml 中数据组件用到的实体名、视图名，jpql 语句，界面控制器的@UiController注解和包名。
