每次连接MYSQL的时候总会提示：
Wed Jul 26 10:18:55 GMT+08:00 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.

翻译一下就是版本太高，连接不上SSL。只要打开你的配置文件将url后面添加一个：?useSSL=true，也就是url=jdbc:mysql://localhost:3306/xianxian?useSSL=true。有些是改成url=jdbc:mysql://localhost:3306/xianxian&useSSL=true。就可以啦~完美
