JDBC:如何读取MySQL点格式

import java.sql.*;

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

        // JDBC连接对象
        Connection connection = null;

        try {
            // 加载JDBC驱动
            Class.forName("com.mysql.jdbc.Driver");

            // 建立数据库连接
            connection = DriverManager.getConnection(url, username, password);

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

            // 执行SQL查询语句
            String sql = "SELECT * FROM mytable";
            ResultSet resultSet = statement.executeQuery(sql);

            // 遍历结果集
            while (resultSet.next()) {
                // 读取点格式数据
                String pointData = resultSet.getString("point_column");
                System.out.println("Point Data: " + pointData);
            }

            // 关闭结果集和Statement对象
            resultSet.close();
            statement.close();
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } catch (SQLException e) {
            e.printStackTrace();
        } finally {
            // 关闭数据库连接
            if (connection != null) {
                try {
                    connection.close();
                } catch (SQLException e) {
                    e.printStackTrace();
                }
            }
        }
    }
