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.

這個代碼是這樣的，google了很多方案，在后面加useSSL=false還是不行
