我正在尝试连接到我的mysql数据库，但出现以下错误：
Thu Jun 13 11:02:30 UTC 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.
我知道我可以通过将useSSL设置为false来解决此问题，但事实是，我已经将来自Let's Encrypt的SSL证书应用于我的Ubuntu 18.04服务器。如何摆脱错误（让MySQL使用SSL证书）？
谢谢！
