Success loading Mysql Driver!
Mon Apr 04 15:43:00 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.
Success connect Mysql server!
首先恭喜，出現這個的時候MySQL說明已經安裝成功了，這是警告不是錯誤，以後使用是不影響的。大概的意思就是說建立ssl連接，但是伺服器沒有身份認證，這種方式不推薦使用。
解決辦法：
原來的連接url：Connection connect = DriverManager.getConnection("jdbc:mysql://localhost:3306/test", "root", "letmein");
現在的連接url:Connection connect = DriverManager.getConnection("jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8&useSSL=false","root", "letmein");
// 連接URL為 jdbc:mysql//伺服器地址/資料庫名 ，後面的2個參數分別是登陸用戶名和密碼
