mysql报错Establishing SSL connection without server's identity verification is not recommended

使用mysql数据库时报错：Establishing SSL connection without server's identity verification is not recommended

解决方法：将url中增加useSSL=false

原代码：String url="jdbc:mysql://localhost:3308/sqltestdb";

改后：String url="jdbc:mysql://localhost:3308/sqltestdb?useSSL=false";
