JDBC连接Mysql

JAVA在连接数据库运行时出现了一行这样的红字：

Thu Aug 11 20:49:11 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.

原因是MySQL在高版本需要指明是否进行SSL连接。

报错时候的代码：

Connection conn = DriverManager.getConnection(“jdbc:mysql://localhost:3306/testjdbc”,”root”,”111”);

解决方案：（加上?characterEncoding=utf8&useSSL=false）

Connection conn = DriverManager.getConnection(“jdbc:mysql://localhost:3306/testjdbc ?characterEncoding=utf8&useSSL=false “,”root”,”111”);
