Tue Aug 15 23:36:34 CST 2023 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.
