[Spring Boot] Mysql8 에러 - WARN: Establishing SSL connection without server's identity verification is not recommended.

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.

 

에러 메세지 처럼 Mysql 5점대 이상의 DB에서 SSL 관련 부분을 분명하게 셋팅하라는 내용이다.
