解决MySQL在高版本需要指明是否进行SSL连接问题

访问出现以下信息

Tue Jul 18 10:03:44 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.

解决方案：
在mysql连接字符串url中加入ssl=true或者false即可

spring.datasource.url=jdbc:mysql://localhost:3306/test?useSSL=true
