Class.forName("com.mysql.jdbc.Driver");
   Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/demo", "root", "123");
以前运行这个是没问题的,今天有出了这个问题

Exception in thread "main" java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/demo
at java.sql.DriverManager.getConnection(Unknown Source)
at java.sql.DriverManager.getConnection(Unknown Source)
at com.itheima.Test8.main(Test8.java:32)
求大神解决一下

貌似是之前听视频老师讲过这个问题,具体记不清了
