如何在java中从房间数据库中获取自动生成的id？

import java.sql.*;

public class RoomDatabaseExample {
    public static void main(String[] args) {
        Connection connection = null;
        Statement statement = null;
        ResultSet resultSet = null;

        try {
            // 1. 连接数据库
            connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/roomdb", "username", "password");

            // 2. 创建查询语句
            String query = "SELECT id FROM rooms ORDER BY id DESC LIMIT 1";

            // 3. 执行查询
            statement = connection.createStatement();
            resultSet = statement.executeQuery(query);

            // 4. 解析结果集
            if (resultSet.next()) {
                int id = resultSet.getInt("id");
                System.out.println("自动生成的ID为：" + id);
            } else {
                System.out.println("未找到自动生成的ID");
            }
        } catch (SQLException e) {
            e.printStackTrace();
        } finally {
            // 5. 关闭连接
            try {
                if (resultSet != null) {
                    resultSet.close();
                }
                if (statement != null) {
                    statement.close();
                }
                if (connection != null) {
                    connection.close();
                }
            } catch (SQLException e) {
                e.printStackTrace();
            }
        }
    }
}
