Question

关于RabitMQ JAVA Queue我有一个错误。当我尝试运行消费者客户端时，他抛出了这个异常。

Exception in thread "main" java.io.IOException

at com.rabbitmq.client.impl.ChannelN.basicConsume(ChannelN.java:1059)
at rabbit.consumer.ConsumerDVD.main(ConsumerDVD.java:52)

原因：com.rabbitmq.client.ShutdownSignalException：频道错误；协议方法：#method（回复代码= 404，回复文本= NOT_FOUND-虚拟主机'/'中没有队列“你好”，类ID = 60，方法ID = 20）在com.rabbitmq.utility.ValueOrException.getValue（ValueOrException.java:67）在com.rabbitmq.utility.BlockingValueOrException.uninterruptibleGetValue（BlockingValueOrException.java:33）在com.rabbitmq.client.impl.AMQChannel $ BlockingRpcContinuation.getReply（AMQChannel.java:361）在com.rabbitmq.client.impl.ChannelN.basicConsume（ChannelN.java:1105） ...另外3个引起原因：com.rabbitmq.client.ShutdownSignalException：通道错误；协议方法：#method（回复代码= 404，回复文本= NOT_FOUND-虚拟主机'/'中没有队列“你好”，类ID = 60，方法ID = 20）在com.rabbitmq.client.impl.ChannelN.asyncShutdown（ChannelN.java:484）在com.rabbitmq.client.impl.ChannelN.processAsync（ChannelN.java:321）在com.rabbitmq.client.impl.AMQChannel.handleCompleteInboundCommand（AMQChannel.java:144）在com.rabbitmq.client.impl.AMQChannel.handleFrame（AMQChannel.java:91）在com.rabbitmq.client.impl.AMQConnection $ MainLoop.run（AMQConnection.java:554）在java.lang.Thread.run（Thread.java:748）

我的代码的一部分：

public class ConsumerDVD {
private final static String QUEUE_NAME = "hello";
private static Writer writer;
 Consumer consumer = new DefaultConsumer(channel) {
        @Override
        public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body)
            throws IOException {
            DVD dvd = DVD.fromBytes(body);
            System.out.println(" [x] Received '" + dvd.toString() + "'");
            mailService.sendMail("cata1096@yahoo.com","Dvd has been added -- Rabbit!", dvd.toString());
            writeToFile(dvd); 
        }
        };
    channel.basicConsume(QUEUE_NAME, true, consumer);

引起原因：com.rabbitmq.client.ShutdownSignalException：通道错误；协议方法：
