下面是代码
//建立与MySQL的连接
import java.sql.*;
public class GetConn {
public Connection conn=null;
public Connection getConnection(){
try{
Class.forName("com.mysql.jdbc.Driver");
String url="jdbc:mysql://loaclhost:3306/scutcs";
String user="root";
String passWord="111";
conn=DriverManager.getConnection(url, user, passWord);
if(conn!=null){
System.out.println("数据库连接成功");
}
}catch(Exception e){
e.printStackTrace();
}
return conn;
}
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
GetConn getConn=new GetConn();
getConn.getConnection();
}
}
