mysql8小时断线
参考https://www.oschina.net/question/1983652_175902?sort=time
注意 其中一位是这样发言的 ”配置testWhileIdle=true就好了“但是只配置这样会报错
java.lang.AbstractMethodError: com.mysql.jdbc.Connection.isValid(I)Z
意思是需要和 validationQuery 这个参数一起使用
最近发现还会报错 ：
00:00:00.321 [task-3] WARN o.s.jdbc.support.SQLErrorCodesFactory[218] - Error while extracting database name - falling back to empty error codes
