Hibernate Spring数据JPA:无法从另一个线程中找到插入的实体

我在主线程中插入一个实体，然后在另一个线程中，我尝试通过使用Spring JPA Repository的JPA查询读取该插入实体的字段modifiedAt

接口结算存款：JPA存款{ /** *获取结算的状态。 */ @查询从结算s中选择s.modifiedAt，其中s.id=：id 有趣的FindModifiedAtById:Long:Instant } /* ... */ val transactionTemplate=TransactionTemplatetransactionManager val结算：列表=transactionTemplate.execute{ amounts.map{ 结算存款。保存结算。。。 } }!! val executorService=Executors.newFixedThreadPool4 弗雷奇酒店{ executorService.execute{ val lastModified=SettlementProposition.findModifiedAtByIdit.id //但有时会抛出EmptyResultDataAccessException！ } } 插入是在TransactionTemplate的事务中完成的，必须在数据库PostgreSQL中持久化和刷新，但有时并不总是抛出EmptyResultDataAccessException

我的代码有什么问题

注意：我已禁用hibernate的缓存级别2

注2：我们在生产中使用

堆栈跟踪：
