java连接mysql，连接不上

需要添加driver的包到java运行环境

Usage: java [-options] class [args...]

(to execute a class)

or java [-options] -jar jarfile [args...]

(to execute a jar file)

where options include:

-d32 use a 32-bit data model if available

-d64 use a 64-bit data model if available

-server to select the "server" VM

The default VM is server.

-cp <class search path of directories and zip/jar files>

String driver="com.mysql.jdbc.Driver"//把driver换成这个重新连接一下，看一下还有错误吗

String url="jdbc:mysql://127.0.0.1:3306/scutcs"//url改成这样
