1. 需要先从2.6.0升级至2.6.1，然后再升级至2.7.0
2. 会有可能升级的时候忽略了一些细节，代码没有升级完整导致出错
3. 看报错是没有链接到数据库，这个与工程无关

The last packet successfully received from the server was 19,170 milliseconds ago. The last packet sent successfully to the server was 19,205 milliseconds ago.大佬，你好！代码我已经更新好了，问题还是没有解决。我今天测试时还会出现下面的问题，就是程序跑起来后隔几个小时后打印数据源连接存在Error。比如下面的日志：2020-11-13 10:08:48.696 程序启动好后，等到下午2020-11-13 14:37:14.306，就出现同样的ERROR 问题了。不知道什么原因会造成什么样的影响，还请大佬明示，非常感谢！

可能原因是我办公室一个服务器开的代理服务影响了druid，目前半个小时了，没再打印连接不上的log。后续我在观察一下，谢谢大佬！
