今天IDEA使用druid连接Mysql数据库报错，MySQL版本5.7.34，druid-spring-boot-starter版本1.1.13。更新druid版本到最新1.2.6也没用。

“The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.”

“No appropriate protocol (protocol is disabled or cipher suites are inappropriate)”
