关于断开 Rabbit MQ 连接的问题

while (falg)
            {
                debuglogger.info("find msg of: " + acid);
                QueueingConsumer.Delivery delivery = consumer.nextDelivery();
                String text = new String(delivery.getBody());
                
                // 解析消息
                String from = "";
                String to = "";
              。。。。。。。。
              }

当我试着去关闭 channel 通道的时候。。报以下错误：

     com.rabbitmq.client.ShutdownSignalException: clean channel shutdown; reason: #method<channel.close>(reply-code=200, reply-text=OK, class-id=0, method-id=0)

原因可能能为我还在不停的从队列中去接受消息，现在去关闭channel的时候。发生异常。。


现在问题是。我要怎么去合理的关闭channel，不会发生异常，或者理解为。怎么样去更好的接受消息？？

求好心人指点。。谢谢。。。
