MySQL Connector java 5.1.x 버전 이상으로는 이런 에러가 생긴다고 한다.

버전을 낮추면 된다.


근데 난 낮추기 싫다. 굳이 안낮춰도 할 수 있으니까.

SSL 미사용 경고


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.
