MYSQL:WARN: Establishing SSL connection without server's identity verification is not recommended.

連接MySQL數據庫時拋出警告：
Tue Feb 26 17:38:27 CST 2019 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.
這是Mysql數據庫的SSL連接問題，提示警告不建議使用沒有帶服務器身份驗證的SSL連接，是在MYSQL5.5.45+, 5.6.26+ and 5.7.6+版本中才有的這個問題

解決

在配置文件application.yml中連接數據庫的url后添加useSSL=false即可
