Answer 1

You need to download and add the jdbc connector to your classpath.

Answer 2

Change

   Connection con = DriverManager.getConnection(url);

to

 Connection con = DriverManager.getConnection(url,"username","password");

and replace it with your username and password

确保您的应用程序类路径上具有MySQL驱动程序。
