Thu Sep 01 21:25:33 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.

出现这个的时候MySQL说明已经安装成功了，这是警告不是错误，以后使用是不影响的。意思就是说建立ssl连接，但是服务器没有身份认证，这种方式不推荐使用。

解决方法： 
原来代码：

conn = DriverManager.getConnection(
                "jdbc:mysql://localhost:3306/testmysql", "root", "");```

• 2

更改之后代码

conn = DriverManager.getConnection(
                "jdbc:mysql://localhost:3306/testmysql?useUnicode=true&characterEncoding=utf-8&useSSL=false", "root", "");

• 1

即在原来的数据库名称后面添加 
?useUnicode=true&characterEncoding=utf-8&useSSL=false
