用TOPIC模式

• *可以代替一個單詞
• #可以替換零個或多個單詞。

1.生產者

package com.baidu.RabbitMQ.mq04;import com.rabbitmq.client.Channel; import com.rabbitmq.client.Connection; import com.rabbitmq.client.ConnectionFactory;public class OneProducer {private static final String Exchange_Name="rabbit:mq04:exchange:e01";public static void main(String[] args) {try {ConnectionFactory factory = new ConnectionFactory();factory.setHost("127.0.0.1");Connection connection = factory.newConnection();Channel channel = connection.createChannel();String message = "topicExchange-publish我的消息";//隊列one收的到 ,隊列two收不到channel.basicPublish(Exchange_Name, "rabbit:mq04:routing:key:r.orange", null, message.getBytes("UTF-8"));//隊列two收的到 ,隊列one收不到channel.basicPublish(Exchange_Name, "rabbit:mq04:routing:key:r.orange.apple", null, message.getBytes("UTF-8"));System.out.println("生產者發送消息成功---> ");channel.close();connection.close();} catch (Exception e) {e.printStackTrace();}} }

2.消費者one

package com.baidu.RabbitMQ.mq04;import java.io.IOException;import com.rabbitmq.client.AMQP; import com.rabbitmq.client.BuiltinExchangeType; import com.rabbitmq.client.Channel; import com.rabbitmq.client.Connection; import com.rabbitmq.client.ConnectionFactory; import com.rabbitmq.client.Consumer; import com.rabbitmq.client.DefaultConsumer; import com.rabbitmq.client.Envelope;public class MultiConsumerOne {private static final String Exchange_Name="rabbit:mq04:exchange:e01";private static final String Queue_Name_01="rabbit:mq04:queue:q01";private static final String Routing_Key_01="rabbit:mq04:routing:key:r.*";public static void main(String[] args) {try {ConnectionFactory factory = new ConnectionFactory();factory.setHost("127.0.0.1");Connection connection = factory.newConnection();Channel channel = connection.createChannel();channel.exchangeDeclare(Exchange_Name, BuiltinExchangeType.TOPIC);channel.queueDeclare(Queue_Name_01, true, false, false, null);channel.queueBind(Queue_Name_01, Exchange_Name, Routing_Key_01);Consumer consumer = new DefaultConsumer(channel) {@Overridepublic void handleDelivery(String consumerTag, Envelope envelope,AMQP.BasicProperties properties, byte[] body) throws IOException {String message = new String(body, "UTF-8");System.out.println("消費者2接收到消息成功---> "+message);}};channel.basicConsume(Queue_Name_01, true, consumer);} catch (Exception e) {e.printStackTrace();}} }

?2.消費者two

package com.baidu.RabbitMQ.mq04;import java.io.IOException;import com.rabbitmq.client.AMQP; import com.rabbitmq.client.BuiltinExchangeType; import com.rabbitmq.client.Channel; import com.rabbitmq.client.Connection; import com.rabbitmq.client.ConnectionFactory; import com.rabbitmq.client.Consumer; import com.rabbitmq.client.DefaultConsumer; import com.rabbitmq.client.Envelope;public class MultiConsumerTwo {private static final String Exchange_Name="rabbit:mq04:exchange:e01";private static final String Queue_Name_02="rabbit:mq04:queue:q02";private static final String Routing_Key_02="rabbit:mq04:routing:key:r.#";public static void main(String[] args) {try {ConnectionFactory factory = new ConnectionFactory();factory.setHost("127.0.0.1");Connection connection = factory.newConnection();Channel channel = connection.createChannel();channel.exchangeDeclare(Exchange_Name, BuiltinExchangeType.TOPIC);channel.queueDeclare(Queue_Name_02, true, false, false, null);channel.queueBind(Queue_Name_02, Exchange_Name, Routing_Key_02);Consumer consumer = new DefaultConsumer(channel) {@Overridepublic void handleDelivery(String consumerTag, Envelope envelope,AMQP.BasicProperties properties, byte[] body) throws IOException {String message = new String(body, "UTF-8");System.out.println("消費者2接收到消息成功---> "+message);}};channel.basicConsume(Queue_Name_02, true, consumer);} catch (Exception e) {e.printStackTrace();}} }
