rabbitMQ：3.7.18

Erlang：22.1

错误消息：

ERROR com.rabbitmq.client.impl.ForgivingExceptionHandler:119 - Consumer com.snsprj.sbsm.mq.rabbitmq.MyConsumer@77fba29d (amq.ctag-Z9h3gT_bM7HibebpYsw6Hg) method handleDelivery for channel AMQChannel(amqp://guest@192.168.1.189:5672/,1) threw an exception for channel AMQChannel(amqp://guest@192.168.1.189:5672/,1)

我的消费者代码：

public class MqConsumer {

        ...

        channel.queueDeclare(QUEUE_NAME_TEST, MqConstant.DURABLE_FALSE, false, MqConstant.AUTO_DELETE_FALSE,null);

        channel.basicConsume(QUEUE_NAME_TEST, false, new MyConsumer(channel));
}

public class MyConsumer extends DefaultConsumer {

    ...

    @Override
    public void handleDelivery(String consumerTag, Envelope envelope, BasicProperties properties, byte[] body)throws IOException {

        String msg = new String(body, StandardCharsets.UTF_8);

        ...
        Thread.sleep(10000L);

        channel.basicAck(envelope.getDeliveryTag(), false);
    }
}

消费者线程.sleep（10000），然后发生错误。仅发出32条消息。有什么问题吗？

com.rabbitmq.client.AlreadyClosedException：由于连接错误，连接已经关闭
