从mysql内部的json拉取数据到java

import java.sql.*;

public class Main {
    public static void main(String[] args) {
        String url = "jdbc:mysql://localhost:3306/database_name";
        String username = "your_username";
        String password = "your_password";

        try {
            Connection connection = DriverManager.getConnection(url, username, password);
            Statement statement = connection.createStatement();
            String query = "SELECT json_column FROM your_table";
            ResultSet resultSet = statement.executeQuery(query);

            while (resultSet.next()) {
                String json = resultSet.getString("json_column");
                // 在这里处理JSON数据
                System.out.println(json);
            }

            resultSet.close();
            statement.close();
            connection.close();
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}
