Hibernate 表中具有并发更新的弹簧锁超时

我正在使用spring boot、hibernate、JPA存储库和事件驱动应用程序的反应器开发一个Web服务。 我已经设置了一组并行运行的长作业，我一直在尝试解决由此异常流引起的错误：

Could not execute statement; SQL [n/a]; nested exception is org.hibernate.PessimisticLockException: could not execute statement
org.springframework.dao.PessimisticLockingFailureException: could not execute statement; SQL [n/a];nested exception is org.hibernate.PessimisticLockException: could not execute statement
...

我得到“表中的并发更新”交互式_实验：另一个事务更新或删除了同一行，我有并发更新，但它们都在不同的行上！ （但它们有一个共同的@manytone字段）

我尝试过乐观和悲观的锁，但都没有解决这个问题。

通过几个并发更新，我得到了这个错误。

现在我已经通过同步更新并设置MVCC=true解决了这个问题
