jdbc4.MySQLNonTransientConnectionException: No operations allowed after connection closed. 雨点打透心脏的1/2处 2023-05-30 06:16 22阅读 0赞 这几日一直在调试我的老古董SSM毕业项目，之前本地调试没有问题，然后部署到远程服务器上就出现问题了，而且偶尔还能正常....... 报错信息如下： Type 异常报告 消息 Request processing failed; nested exception is org.springframework.transaction.CannotCreateTransactionException: Could not open JDBC Connection for transaction; nested exception

Note 主要问题的全部 stack 信息可以在 server logs 里查看 排查方式可以肯定不是代码逻辑问题，报错信息说的是远程数据库连接不上，也就是说数据库拒绝连接请求。后来我发现我远程数据库使用的是5.7版本的，可能我的数据库驱动的问题 ![20191107204219333.png][] 我回到我的项目里看了一下我的数据库驱动，发现好久以前导入的数据库驱动使用的是2016就已经停止维护的驱动版本 ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM3OTA5NTA4_size_16_color_FFFFFF_t_70][]
