如何将MySQL查询的结果映射到java模型类中？

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.ArrayList;
import java.util.List;

public class MySQLMapperExample {
    public static void main(String[] args) {
        // MySQL连接信息
        String url = "jdbc:mysql://localhost:3306/mydatabase";
        String username = "root";
        String password = "password";

        try {
            // 连接MySQL数据库
            Connection conn = DriverManager.getConnection(url, username, password);

            // 创建Statement对象
            Statement statement = conn.createStatement();

            // 执行查询语句
            ResultSet resultSet = statement.executeQuery("SELECT * FROM users");

            // 创建模型对象列表
            List<UserModel> userList = new ArrayList<>();

            // 遍历结果集
            while (resultSet.next()) {
                // 创建模型对象
                UserModel user = new UserModel();

                // 将结果映射到模型对象
                user.setId(resultSet.getInt("id"));
                user.setName(resultSet.getString("name"));
                user.setAge(resultSet.getInt("age"));

                // 添加到模型对象列表
                userList.add(user);
            }

            // 关闭连接
            resultSet.close();
            statement.close();
            conn.close();

            // 打印模型对象列表
            for (UserModel user : userList) {
                System.out.println(user.toString());
            }
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}

class UserModel {
    private int id;
    private String name;
    private int age;

    // getters and setters...

    @Override
    public String toString() {
        return "UserModel{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", age=" + age +
                '}';
    }
}
