mysql连接失败:The driver has not received any packets from the server

java spring项目连接mysql报错,可以确认mysql自身没问题,数据库权限及网络连接均正常

Mysql数据库版本:mysql-5.7.30
Mysql客户端:mysql-connector-j-8.0.31.jar
HikariCP-4.0.3.jar

应用日志报错如下:

配置文件:
spring:
  datasource:
    url: mydbm01.sudops.com:3306/sudops?useSSL=false&serverTimezone=UTC
    username: dbuesr
    password: dbpwd

解决方案:

修改mysql连接串,增加 autoReconnect 和 failOverReadOnly
jdbc:mysql://mydbm01.sudops.com:3306/sudops?useSSL=false&serverTimezone=UTC&autoReconnect=true&failOverReadOnly=false 释义: autoReconnect: 当数据库连接异常中断时,是否自动重新连接? failOverReadOnly: 自动重连成功后,连接是否设置为只读?
