我的Java应用程序运行良好,并且在故障转移后将数据插入Aurora-Mysql,故障转移后出现错误“通信链接故障”。我们的Aurora-Mysql是2节点群集。
以下是错误: 不会打开Hibernate Session进行交易;嵌套的异常是org.hibernate.TransactionException:JDBC开始事务失败:

。 任何建议

不确定我是否完全理解您的问题,但看起来您的应用程序运行良好,然后在群集进行故障转移时,您的应用程序停止工作并出现了许多错误。
您共享的堆栈跟踪信息表明该应用程序已检测到连接关闭,但仍在继续使用旧连接来打开新事务。如果连接最终被关闭,您是否有逻辑来优雅地重新打开连接?与使用持久连接的数据库进行交互时,这是一种常见的范例。
