Spring boot 에서 Mysql을 붙일 때 server certificate verification 관련 경고가 뜨는 경우

Mysql 연동 시 server certificate verification 경고 발생

Tue Dec 11 13:29:36 KST 2018 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.
