package com.imooc;

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.ResultSet;

import java.sql.Statement;

public class DBUtil {

private static final String URL="jdbc:mysql://127.0.0.1:3306/imooc";//地址

private static final String USER="root";

private static final String PASSWORD="123456";

public static void main(String[] args) throws Exception {

// TODO Auto-generated method stub

//1、加载驱动程序

Class.forName("com.mysql.jdbc.Driver");

//2、获得数据库连接

Connection conn= DriverManager.getConnection(URL, USER, USER);

//通过数据库连接操作数据库，实现增删改查;

Statement sat= conn.createStatement();

ResultSet rs=sat.executeQuery("Select user_name,age from imooc_goddess");

while(rs.next())

{

System.out.println(rs.getString("user_name")+","+rs.getInt("age"));

}

}

}

为什么我的代码不行啊？求各位大神指点
