rabbitmq五---接收符合特定路由规则的消息

发送端：

channel.exchangeDeclare(EXCHANGE_NAME, "topic");//声明topic类型的ExchangeString routingKeyOne = "logs.error.one";// 定义一个路由名为“error”for (int i = 0; i <= 1; i++) {      String messageOne = "this is one error logs:" + i;      channel.basicPublish(EXCHANGE_NAME, routingKeyOne, null, messageOne.getBytes());      System.out.println(" [x] Sent '" + routingKeyOne + "':'"+ messageOne + "'");  }  System.out.println("################################");  String routingKeyTwo = "logs.error.two";  for (int i = 0; i <= 2; i++) {      String messageTwo = "this is two error logs:" + i;      channel.basicPublish(EXCHANGE_NAME, routingKeyTwo, null, messageTwo.getBytes());      System.out.println(" [x] Sent '" + routingKeyTwo + "':'" + messageTwo + "'");  }  System.out.println("################################");  String routingKeyThree = "logs.info.one";  for (int i = 0; i <= 3; i++) {     String messageThree = "this is one info logs:" + i;     channel.basicPublish(EXCHANGE_NAME, routingKeyThree, null,messageThree.getBytes());     System.out.println(" [x] Sent '" + routingKeyThree + "':'"+ messageThree + "'");  }  channel.close();  connection.close();

接收端1：

channel.exchangeDeclare(EXCHANGE_NAME, "topic");// 声明topic类型的ExchangeString queueName = "queue_topic_logs1";// 定义队列名为“queue_topic_logs1”的Queuechannel.queueDeclare(queueName, false, false, false, null);  //      String routingKeyOne = "*.error.two";// "error"路由规则//      channel.queueBind(queueName, EXCHANGE_NAME, routingKeyOne);// 把Queue、Exchange及路由绑定String routingKeyTwo = "logs.*.one";//通配所有logs下第三词（最后一个）词为one的消息channel.queueBind(queueName, EXCHANGE_NAME, routingKeyTwo);  System.out.println(" [*] Waiting for messages.");  QueueingConsumer consumer = new QueueingConsumer(channel);  channel.basicConsume(queueName, true, consumer);  while (true) {       QueueingConsumer.Delivery delivery = consumer.nextDelivery();       String message = new String(delivery.getBody());       String routingKey = delivery.getEnvelope().getRoutingKey();       System.out.println(" [x] Received '" + routingKey + "':'" + message  + "'");  }  

接收端2：
