The version of MySQL is too high and does not match mysql-connection-java-5.1.18. Change to 5.1.46 to match successfully. When changing the jar package, add it at the connection
Sat May 18 16:43:41 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.
