According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default
当前版本的MySQL要求使用SSL,做出如下修改即可:将connection=DriverManager.getConnection("jdbc:mysql://localhost:3306/jsp_db","root","123456");改成connection=DriverManager.getConnection("jdbc:mysql://localhost:3306/jsp_db?us
