求大神提出解决的办法
package com.imooc.db;
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";
private static final String USER="root";
private static final String PASSWORD="195723";
public static void main(String[] args) throws Exception {
//1.加载驱动程序
Class.forName("com.mysql.jdbc.Driver");
//2.获得数据库的连接
Connection conn=DriverManager.getConnection(URL, USER, PASSWORD);
//3.通过数据库的连接操作数据库,实现增删改查
Statement stmt=conn.createStatement();
ResultSet rs=stmt.executeQuery("select user_name,age from imooc_goddess");
while(rs.next()) {
System.out.println(rs.getString("user_name")+","+rs.getInt("age"));
}
}
}
