     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

    Communications link failure

    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!
