如何在java中删除兔MQ中的所有消息

import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;

public class RabbitMQMessageDeletion {
    private static final String QUEUE_NAME = "my_queue";

    public static void main(String[] args) {
        ConnectionFactory factory = new ConnectionFactory();
        factory.setHost("localhost");
        factory.setUsername("guest");
        factory.setPassword("guest");

        try (Connection connection = factory.newConnection();
             Channel channel = connection.createChannel()) {
            channel.queueDeclare(QUEUE_NAME, false, false, false, null);
            channel.basicPurge(QUEUE_NAME);
            System.out.println("All messages deleted from the queue.");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
