IDEA 运行报错：WARN: Establishing SSL connection

使用JDBC连接数据库时出现报错，

报错内容：
Wed Sep 26 14:30:31 CST 2018 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.

3月21日星期三09:28:33 CST 2018警告：没有服务器的身份验证建立SSL连接，不推荐。根据MySQL 5.5.45 +，+，+ 5.6.26 5.7.6要求SSL连接必须建立明确的选项默认情况下如果不设置。符合现有的应用程序不使用SSL的verifyservercertificate属性设置为“false”。你需要显式禁用SSL设置usessl = false，或设置usessl =真实提供服务器证书验证信任库。

解决办法：
修改数据库连接配置，加上useSSL=false即可
