場景復現

mysql數據庫 5.7.24

jdbc driver: mysql-connector-java: 5.1.33

jdbc 配置: 
+ jdbc.url
+ driverName: 

Tomcat報錯:
MySQLNonTransientConnectionException: Could not create connection to database server.

解決

jdbc driver: mysql-connector-java.jar 從5.1升級到8.0

jdbc 配置:
+ jdbc.url: &useSSL=false
+ driverName: com.mysql.cj.jdbc.Driver

遺留問題：

mysql負載高，如何分析和解決？
