import java.sql.Statement;
public class DBUtil {
private static final String URL="jdbc:mysql://127.0.0.1:3306/imooc";

Class.forName("com.mysql.jdbc.Driver");
Connection conn=DriverManager.getConnection(URL, USER, PASSWORD);
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"));
