在java中为group by函数运行sense查询

import java.sql.*;
import java.util.*;

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

        try (Connection connection = DriverManager.getConnection(url, username, password)) {
            String query = "SELECT column1, SUM(column2) FROM table_name GROUP BY column1";
            Statement statement = connection.createStatement();
            ResultSet resultSet = statement.executeQuery(query);

            while (resultSet.next()) {
                String column1Value = resultSet.getString(1);
                int sumValue = resultSet.getInt(2);

                System.out.println("Column1: " + column1Value + ", Sum: " + sumValue);
            }
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}
