使用Java连接到MySQL数据库时出错

Question

代码：

package hw02;
import java.sql.*;

public class HW02 
{   
    public static void main(String[] args) throws 
             SQLException,ClassNotFoundException
    {
            Class.forName("com.mysql.jdbc.Driver");

            System.out.println("Driver loaded");

            String url = "jdbc:mysql://localhost/";

            Connection conn = DriverManager.getConnection (url, "root", 
             "sesame");


            System.out.println("Databse connected");
            //Create a statement"
            Statement statement = conn.createStatement();

            ResultSet resultSet = statement.executeQuery("select * from 
            Phones.Products");
            System.out.println("ResultSet completed");

            while (resultSet.next()) 
            {
                System.out.println(resultSet.getString(1)+"\t" + 
                resultSet.getString(2) + "\t" +
                        resultSet.getString(3) + "\t" + "\n");
            }
            //close the connection   
    }  
}

这会不断出现Casting错误提示

 Exception in thread "main" java.sql.SQLException: 
 java.lang.ClassCastException: java.math.BigInteger cannot be cast to 
 java.lang.Long
    at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:1074)
    at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:988)
    at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:974)
    at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:919)
    at 

我环顾四周，人们建议更换连接器，但我不知道该怎么做。
