RabbitMQ学习(五)_Hello World

一、生产者代码：

自行导入相关依赖包或相关依赖

        ConnectionFactory factory = new ConnectionFactory();

        factory.setHost("localhost");

        factory.setUsername("username");

        factory.setPort(5672);//注意这里的端口与管理插件的端口不一样

        factory.setPassword("pwd");

        Connection connection = factory.newConnection();

        Channel channel = connection.createChannel();

        //声明一个dirent模式的交换机

        channel.exchangeDeclare("exchange_name",BuiltinExchangeType.DIRECT,true);

        //声明一个非持久化自动删除的队列

        channel.queueDeclare("queue_name",false,false,true,null);//如果该队列不在被使用就删除他 zhe

        //将绑定到改交换机

        channel.queueBind("queue_name","exchange_name","route_key");

        //声明一个消息头部

        Map<String,Object> header=new HashMap<>();

        AMQP.BasicProperties.Builder b= new AMQP.BasicProperties.Builder();

        header.put("charset","utf-8");

        b.headers(header);

        AMQP.BasicProperties bp=b.build();

        //将消息发出去

       channel.basicPublish("exchange_name","route_key",false,bp,"test3".getBytes());

二、消费者代码

  ConnectionFactory factory = new ConnectionFactory();

  factory.setHost("localhost");

  factory.setUsername("username");

  factory.setPort(5672);//注意这里的端口与管理插件的端口不一样

  factory.setPassword("pwd");

  Connection connection = factory.newConnection();

  Channel channel = connection.createChannel();

  //声明一个dirent模式的交换机

  channel.exchangeDeclare("exchange_name",BuiltinExchangeType.DIRECT,true);

  //声明一个非持久化自动删除的队列

  channel.queueDeclare("queue_name",false,false,true,null);//如果该队列不在被使用就删除他 zhe

  //将绑定到改交换机

  channel.queueBind("queue_name","exchange_name","route_key");

  Consumer consumer = new DefaultConsumer(channel) {

      @Override

      public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties,

                                 byte[] body) throws IOException {

          String message = new String(body, "UTF-8");

          System.out.println(" [x] Received '" + message + "'");

      }

  };

  channel.basicConsume("queue_name", true, consumer);
