Java 连接mysql数据库warn：Establishing SSL connection without server's identity verification is not ...

连接数据库时运行成功，查询结果也有，但是控制台却报出警告。

警告信息如下:

Fri Jul 21 13:55:07 CST 2017 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.

根据信息可以得知mysql5.5.45之后的版本要求建立的连接指明是否为ssl 连接，在URL 后面加上参数useSSL=false 或者useSSL=true 可解决

如：

url=jdbc:mysql://localhost:3306/vinfung?useSSL=true
