不幸的是，在这种情况下，其他实体名称，模式名称不起作用。我不明白这个解释的描述。这是什么意思？jpa必须为序号字段定义非只读映射

没有什么特殊的，他们深受我的测试。

也将hibernate.hbm2ddl.auto从“更新”更改为“创建”例如不成功
P.S.
门票后面的@ManyToOne行&司机实体被评论为免除。但在这种情况下什么是错的。
在这个项目中，我有票< - > tickets_drivers < - >司机多对多的连接，我没有使用@ManyToMany，因为谷歌说，如果我有一个或多个额外的字段在连接表我必须使用@OneToMany两次。它可能是这个错误的原因？！
为什么在错误与EclipseLink（一个不同的JPA提供程序）相关时为Hibernate标记问题？ –
是的，我已经删除它 – Nesquik27
，为什么不删除所有的Hibernate配置和关于改变一些休眠属性的线？哦，和openJPA属性！然后将其标记为Eclipselink！ –
