SQL：从 jhi_persistent_audit_event 中删除 event_id=? ，批量更新从更新 [0] 返回了意外的行数；

数据库是Mysql
删除一条根本不存在的记录时，可能会发生此异常。那么我该如何解决 JHipster。
你觉得这个SQL叫什么地方？
这发生在 AuditEventService 的 removeOldAuditEvents 方法中，在 class 级别用 @Transactionnal 注释。
此方法已 @Scheduled 注释，您的应用程序有多个实例 运行。因此，每天在同一时间，您的所有实例都会竞相清除超过 30 天的事件。
这是一个class多实例应用中批处理作业的典型案例。
所以，你有几个选择：
- select 负责清除事件的实例可能具有 spring 配置文件
- 通过将您的清除方法公开为 API 端点（请参阅
AuditResource）来正确保护您将从 cron 或任何外部调度程序调用并使用 API仅路由到一个实例的网关
- catch
ObjectOptimisticLockingFailureException 并在该方法中忽略它；一般来说，不推荐这样做，但在这种情况下，我想这是可以接受的，因为一个实例会成功，这就是你想要的。也许配置悲观锁定是有意义的。
- 在数据库或 Hazelcast 中实施分布式锁，您可能已经将其用于分布式缓存
