在连接mysql中出现如下警告

Fri Oct 28 02:21:53 CST 2016 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：

原因是在MySQL高版本中需要指明是否进行SSL连接。

连接字符串url中加入ssl=true或false即可：

String url = "jdbc:mysql://localhost:3306/test?characterEncoding=utf8&useSSL=true";

这儿最好上characterEncoding=utf8，因为高版本的MySQL支持中文，

如果不写上就会出现执行含有中文的sql语句失败的情况。
