我的代码如下。错误发生在线路上 “conn = DriverManager.getConnection(url+dbName,userName,password);”
public class ConnectingToDB
{
public static void main(String[] args)
{
System.out.println("MySQL Connect Example.");
Connection conn = null;
String url = "jdbc:mysql://localhost:3306/";
String dbName = "steven";
String driver = "com.mysql.jdbc.Driver";
String userName = "db";
String password = "db";
try
{
Class.forName(driver).newInstance();
conn = DriverManager.getConnection(url+dbName,userName,password);
System.out.println("Connected to the database");
conn.close();
System.out.println("Disconnected from database");
}
catch (Exception e) {
e.printStackTrace();
}
}
