rabbitmq五---接收符合特定路由規則的消息

發送端：

channel.exchangeDeclare(EXCHANGE_NAME, "topic");//聲明topic類型的Exchange
String routingKeyOne = "logs.error.one";// 定義一個路由名爲“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");// 聲明topic類型的Exchange
String queueName = "queue_topic_logs1";// 定義隊列名爲“queue_topic_logs1”的Queue
channel.queueDeclare(queueName, false, false, false, null);  
//      String routingKeyOne = "*.error.two";// "error"路由規則
//      channel.queueBind(queueName, EXCHANGE_NAME, routingKeyOne);// 把Queue、Exchange及路由綁定
String routingKeyTwo = "logs.*.one";//通配所有logs下第三詞（最後一個）詞爲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：

channel.exchangeDeclare(EXCHANGE_NAME, "topic");//聲明topic類型的Exchange
String queueName = "queue_topic_logs2";//定義隊列名爲“queue_topic_logs2”的Queue
channel.queueDeclare(queueName, false, false, false, null);  
String routingKeyOne = "logs.#";//通配所有logs下的消息
channel.queueBind(queueName, EXCHANGE_NAME, routingKeyOne);//把Queue、Exchange及路由綁定
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 + "'");
