当后端数据库（Mysql InnoDB集群）以多主模式运行时，Spring shedlock表更新行提交失败

Question

部署在 OCP 中的 Spring Boot 微服务，并使用 mysql-router 映像连接到后端数据库。该服务包含一个调度程序类（使用 @scheduled 注释）来基于 cron 表达式执行某些工作流程。该微服务正在多个节点上运行。

为了阻止调度程序类从所有节点执行，SHEDLOCK 实现已完成。当后端数据库（Mysql Inno DB 集群）以单主模式运行时，此设置完美运行。

最近，我们将数据库模式从单主模式更改为多主模式，同样mysql-router配置也从第一个可用模式更改为循环模式。在此实现之后，当 SHEDLOCK 库尝试更新 SHEDLOCK 表中的锁定计时时，jdbc 执行失败并出现以下错误。请帮助解决这个问题。
