如何在java中从MySQL检索查询的结果集

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

public void queryDatabase() {
    // 设置数据库连接参数
    String url = "jdbc:mysql://localhost:3306/your_database_name";
    String username = "your_username";
    String password = "your_password";

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

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

        // 创建一个Statement对象
        Statement statement = connection.createStatement();

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

        // 遍历查询结果
        while (resultSet.next()) {
            // 获取查询结果中的列值
            int id = resultSet.getInt("id");
            String name = resultSet.getString("name");

            // 输出结果
            System.out.println("ID: " + id + ", Name: " + name);
        }

        // 关闭资源
        resultSet.close();
        statement.close();
        connection.close();
    } catch (Exception e) {
        e.printStackTrace();
    }
}
