项目连接mysql的时候出现如下的错误信息：

Mon Dec 21 12:24:01 CST 2020 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.

解决办法：在jdbc的url后面加上useSSL=false参数。

jdbc_url=jdbc:mysql://xxxx:3306/ms?useUnicode=true&characterEncoding=utf8&allowMultiQueries=true&useSSL=false
