Establishing SSL connection without server's identity verification is not recommended.
1、问题:Java使用 mysql-jdbc 连接 MySQL 出现的警告:
全称如下:
WARN: Establishing SSL connection without server's identity verification is not recommended.
According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set.
For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'.
You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.
2、其实上面的警告已经给出提示了,by setting useSSL=false, or set useSSL=true
原因是MySQL在高版本需要指明是否进行SSL连接。解决方案如下:
可以在JDBC的配置里面添加 useSSL=true 配置使用 SSL连接 即可
如下所示:
