首先可以去官方看看第三章節(jié)講的一些內(nèi)容：https://www.rabbitmq.com/tutorials/tutorial-three-java.html

RabbitMQ中消息傳遞模型的核心思想是生產(chǎn)者永遠(yuǎn)不會(huì)將任何消息直接發(fā)送到隊(duì)列。

實(shí)際上，生產(chǎn)者通常甚至不知道消息是否會(huì)被傳遞到任何隊(duì)列。

相反，生產(chǎn)者只能向Exchanges(交換機(jī))發(fā)送消息。交換是一件非常簡(jiǎn)單的事情。

一方面，它接收來(lái)自生產(chǎn)者的消息，另一方面將它們推送到隊(duì)列。

Exchanges(交換機(jī))必須確切知道如何處理它收到的消息。

Exchanges(交換機(jī))有幾種交換類(lèi)型可供選擇：direct,?topic,?headers?and?fanout

本文采用的fanout（廣播模式）

1.生產(chǎn)者?

package com.baidu.RabbitMQ.mq02;import com.rabbitmq.client.BuiltinExchangeType; 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:mq02: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();//TODO：fanout-exchange無(wú)意識(shí)分發(fā)消息模型channel.exchangeDeclare(Exchange_Name, BuiltinExchangeType.FANOUT);String message = "fanoutExchange-publish的消息";channel.basicPublish(Exchange_Name, "", null, message.getBytes("UTF-8"));System.out.println("生產(chǎn)者發(fā)送消息成功---> ");channel.close();connection.close();} catch (Exception e) {e.printStackTrace();}} }

?2.消費(fèi)者one

package com.baidu.RabbitMQ.mq02;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:mq02:exchange:e01";private static final String Queue_Name_01="rabbit:mq02:queue:q01";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();//TODO：fanout-exchange無(wú)意識(shí)分發(fā)消息模型-綁定channel.exchangeDeclare(Exchange_Name, BuiltinExchangeType.FANOUT);channel.queueDeclare(Queue_Name_01, true, false, false, null);channel.queueBind(Queue_Name_01, Exchange_Name, "");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(fèi)者1接收到消息成功---> "+message);}};channel.basicConsume(Queue_Name_01, true, consumer);} catch (Exception e) {e.printStackTrace();}} }

?3.消費(fèi)者two

package com.baidu.RabbitMQ.mq02;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:mq02:exchange:e01";private static final String Queue_Name_02="rabbit:mq02:queue:q02";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();//TODO：fanout-exchange無(wú)意識(shí)分發(fā)消息模型channel.exchangeDeclare(Exchange_Name, BuiltinExchangeType.FANOUT);channel.queueDeclare(Queue_Name_02, true, false, false, null);channel.queueBind(Queue_Name_02, Exchange_Name, "");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(fèi)者2接收到消息成功---> "+message);}};channel.basicConsume(Queue_Name_02, true, consumer);} catch (Exception e) {e.printStackTrace();}} }
