在启动RabbitMQ消费端的时候报错:Caused by: com.rabbitmq.client.ShutdownSignalException: channel error; protocol method: #method<channel.close>(reply-code=406, reply-text=PRECONDITION_FAILED - inequivalent arg 'type' for exchange 'messageChange' in vhost '/': received 'fanout' but current is 'direct', class-id=40, method-id=10)

仔细看一下报错信息:Caused by: com.rabbitmq.client.ShutdownSignalException: channel error; protocol method: #method<channel.close>(reply-code=406, reply-text=PRECONDITION_FAILED - inequivalent arg 'type' for exchange 'messageChange' in vhost '/': received 'fanout' but current is 'direct', class-id=40, method-id=10)
大概意思是交换机的类型不匹配,消费端应该收到名称为“messageChange”,类型为“fanout”的交换机发送的消息,但是当前RabbitMQ中存在的名称为“messageChange”的交换机的类型却是“direct”,所以交换机的类型不匹配。
打开RabbitMQ可以看到确实是这样:
目前有两种解决方式:
一、更改消费端代码中声明的交换机名称即可;
二,把RabbitMQ中的同名却不同类型的交换机删除即可;
消费端代码如下,交换机名称为“messageChange”,类型为“fanout”;
package xyfer; import com.rabbitmq.client.*; import java.io.IOException; import java.util.concurrent.TimeoutException; public class Consumer02 { //Publish/subscribe发布订阅模式 private static final String QUEUE_SMS ="queueSms"; private static final String EXCHANGE = "messageChange"; 同名 public static void main(String[] args) { Connection connection = null; Channel channel = null; try { ConnectionFactory connectionFactory = new ConnectionFactory(); connectionFactory.setHost("127.0.0.1"); connectionFactory.setPort(5672); connection = connectionFactory.newConnection(); channel = connection.createChannel(); //通道绑定交换机 /** * 参数明细 * 1、交换机名称 * 2、交换机类型,fanout、topic、direct、headers */ //Publish/subscribe发布订阅模式 channel.exchangeDeclare(EXCHANGE, BuiltinExchangeType.FANOUT); 不同类型 //通道绑定队列 /** * 声明队列,如果Rabbit中没有此队列将自动创建 * param1:队列名称 * param2:是否持久化 * param3:队列是否独占此连接 * param4:队列不再使用时是否自动删除此队列 * param5:队列参数 * String queue, boolean durable, boolean exclusive, boolean autoDelete, Map<String, Object> arguments * */ channel.queueDeclare(QUEUE_SMS,true,false,false,null);//通道绑定短信队列 //交换机和队列绑定 /** * 参数明细 * 1、队列名称 * 2、交换机名称 * 3、路由key */ //Publish/subscribe发布订阅模式 channel.queueBind(QUEUE_SMS,EXCHANGE,""); DefaultConsumer consumer = new DefaultConsumer(channel) { /** * 消费者接收消息调用此方法 * @param consumerTag 消费者的标签,在channel.basicConsume()去指定 * @param envelope 消息包的内容,可从中获取消息id,消息routingkey,交换机,消息和重传标志 (收到消息失败后是否需要重新发送) * @param properties * @param body * @throws IOException * String consumerTag, Envelope envelope, BasicProperties properties, byte[] body */ @Override public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body) throws IOException { //交换机 String exchange = envelope.getExchange(); //路由key String routingKey = envelope.getRoutingKey(); envelope.getDeliveryTag(); String msg = new String(body,"utf-8"); System.out.println("mq收到的消息是:"+msg ); } }; System.out.println("消费者启动成功!"); channel.basicConsume(QUEUE_SMS,true,consumer); } catch (IOException e) { e.printStackTrace(); } catch (TimeoutException e) { e.printStackTrace(); } } }
