java根据rabbitmq队列名称获取队列Queue 对象

可以使用RabbitMQ Java客户端来获取队列对象。以下是一个示例代码：

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

public class QueueGetter {
    private static final String QUEUE_NAME = "myQueue";
    private static final String HOST = "localhost";
    private static final int PORT = 5672;
    private static final String USERNAME = "guest";
    private static final String PASSWORD = "guest";

    public static void main(String[] args) throws Exception {
        ConnectionFactory factory = new ConnectionFactory();
        factory.setHost(HOST);
        factory.setPort(PORT);
        factory.setUsername(USERNAME);
        factory.setPassword(PASSWORD);

        Connection connection = factory.newConnection();
        Channel channel = connection.createChannel();

        // 声明队列
        DeclareOk declareOk = channel.queueDeclarePassive(QUEUE_NAME);

        System.out.println("队列名称: " + declareOk.getQueue());
        System.out.println("消息数量: " + declareOk.getMessageCount());
        System.out.println("消费者数量: " + declareOk.getConsumerCount());

        channel.close();
        connection.close();
    }
}

在上面的代码中，我们使用channel.queueDeclarePassive()方法来声明队列，该方法返回一个DeclareOk对象，其中包含了队列的名称、消息数量和消费者数量等信息。

请确保使用正确的RabbitMQ连接参数，例如主机名、端口号、用户名和密码
