消息队列服务器核心功能就是，提供了虚拟主机，交换机， 队列，消息等概念的管理，实现三种典型的消息转发方式，可以实现跨主机/服务器之间的生产者消费模型。
这里，就编写一个demo，实现跨主机的生产者消费者模型。
🍅 完善服务器的启动类
@SpringBootApplication
public class TigerMqApplication {public static ConfigurableApplicationContext context;public static void main(String[] args) throws IOException {context = SpringApplication.run(TigerMqApplication.class, args);BrokerServer brokerServer = new BrokerServer(9090);brokerServer.start();}
}🍅 创建Demo程序
/*
* 表示一个生产者
* */
public class DemoProducer {public static void main(String[] args) throws IOException, InterruptedException {System.out.println("启动生产者");ConnectionFactory factory = new ConnectionFactory();factory.setHost("127.0.0.1");factory.setPort(9090);Connection connection = factory.newConnection();Channel channel = connection.createChannel();// 创建交换机和队列channel.exchangeDeclare("testExchange", ExchangeType.DIRECT,true,false,null );channel.queueDeclare("testQueue",true,false,false,null);// 创建一个消息并且发送byte[] body = "hello,TigerMQ".getBytes();boolean ok = channel.basicPublish("testExchange","testQueue",null,body);System.out.println("消息投递完成！ok = " + ok);Thread.sleep(500);channel.close();connection.close();}
}
/*
* 表示一个消费者
* */
public class DemoConsumer {public static void main(String[] args) throws IOException, MqException, InterruptedException {System.out.println("启动消费者！");ConnectionFactory factory = new ConnectionFactory();factory.setHost("127.0.0.1");factory.setPort(9090);Connection connection = factory.newConnection();Channel channel = connection.createChannel();channel.exchangeDeclare("testExchange", ExchangeType.DIRECT,true,false,null);channel.queueDeclare("testQueue",true,false,false,null);channel.basicConsume("testQueue", true, new Consumer() {@Overridepublic void handleDelivery(String consumerTag, BasicProperties basicProperties, byte[] body) throws MqException, IOException {System.out.println("[消费数据]开始！");System.out.println("consumerTag = " + consumerTag);System.out.println("basicProperties = " + basicProperties);String bodyString = new String(body,0, body.length);System.out.println("body = " + bodyString);System.out.println("[消费数据]结束！");}});// 一直等待消费while (true){Thread.sleep(500);}}
}
🍅 启动服务器和客户端程序
