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.
翻译：
警告:不建议在没有服务器身份验证的情况下建立SSL连接。根据MySQL 5.5.45+，如果没有设置显式选项，默认情况下必须建立5.6.26+和5.7.6+要求的SSL连接。您需要通过设置useSSL=false显式禁用SSL，或者设置useSSL=true并为服务器证书验证提供信任存储。
其实这个错并不用管，如果看着烦可以加上这句话
?useUnicode=true&characterEncoding=utf-8&useSSL=true如下：
