获得；org.hibernate.transientObject异常：代理未与会话关联；使用jpa保存实体时出错

我已将spring boot版本从1.5.7升级到2.1.8。 以前的代码工作得很好，但现在当我保存实体时，我得到了堆栈跟踪。 我们正在使用jpa hibernate。hibernate版本即将推出spring boot，我们还没有强制推出任何hibernate版本。 我们在EnableJpaRepositories注释中使用扩展的SimpleJpaRepository类

我们正在使用以下版本的库- org.hibernate:hibernate核心：5.3.11.Final org.springframework.data:spring数据jpa:2.1.10.RELEASE

堆栈跟踪：
