您能将操作员ID记录在OperatorDAO.delete中吗？类似于：logger.debugdelete方法已使用>+operatorId+@SergeBallesta启动，在我的堆栈跟踪中，有一个日志选择ID、地址、银行帐户、名称、电话、来自OPERATOR的版本，其中ID=？绑定=>[{id:OPE000000000001}]。我确信在日志中有记录，findAllOperator程序已经完成。。。然后参与事务失败-将现有事务标记为仅回滚。你知道为什么交易会倒退吗？直接在数据库中执行时，是否从操作员处选择ID、地址、银行帐户、姓名、电话、版本，其中ID='OPE000000000001'有效？@PredFragmaric，是，事务回滚。我认为，因为select记录是空的。直接在数据库中执行查询时的工作。从操作员处选择ID、地址、银行帐户、姓名、电话、版本，其中ID='OPEG000000000001'是否在数据库中工作？从日志判断，在此之前，您正在调用getAllOperators，几乎在同一毫秒内，是否会有一些事务重叠？您是否可以隔离测试用例以删除操作符，甚至使用硬编码id？
