错误描述：
如果你用的是java13报错：： 如果你用的是java8报错：：
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.
解决： 在你的URL后面加?useSSL=false 如果有问号 则跟上&useSSL=false 就可 例子：eesy是我的数据库名
