eclipse怎么配置mysql数据库

import java.sql.*;

public class MySQLExample {
    public static void main(String[] args) {
        try {
            // 加载MySQL驱动程序
            Class.forName("com.mysql.jdbc.Driver");

            // 连接到数据库
            Connection connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/mydatabase", "username", "password");

            // 执行SQL查询
            Statement statement = connection.createStatement();
            ResultSet resultSet = statement.executeQuery("SELECT * FROM mytable");

            // 处理查询结果
            while (resultSet.next()) {
                String column1 = resultSet.getString("column1");
                String column2 = resultSet.getString("column2");
                System.out.println(column1 + " " + column2);
            }

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