spring boot 整合 amqp

安装RabbitMQ server

• 浏览器访问https://www.rabbitmq.com/install-standalone-mac.html，下载RabbitMQ server

• 解压下载的文件

  tar -zxvf rabbitmq-server-mac-standalone-3.6.6.tar.xz
  

进入解压得到的文件夹中的sbin目录

  执行 ./rabbitmq-server
  按CRTL+C关闭启动的server
  ./rabbitmq-plugins enable rabbitmq_management
  ./rabbitmq-server
  通过浏览器打开[http://localhost:15672/](http://localhost:15672/)   
  用户名和密码 是 guest／guest

安装RabbtMQ Server操作详细见http://blog.csdn.net/mrzhangxl/article/details/53114616

编写代码

• 先看一下项目目录

编写amqp-sender

• 在pom.xml中引入amqp依赖包

  
    
    
        org.springframework.boot
        spring-boot-starter-amqp
    
  
    
        org.springframework.boot
        spring-boot-starter-web
    
  
    
        org.springframework.boot
        spring-boot-starter-test
    
  
  

• 配置application.yml

  spring:
    rabbitmq:
        host: localhost
        port: 5672
        username: guest
        password: guest
  

• 编写amqp-sender 配置类

  @Configuration
  public class RabbitMQConfig {
    public static final String QUEUE_NAME = "spring-boot";
    public static final String QUEUE_EXCHANGE_NAME = "spring-boot-exchange";
  
    @Bean
    public Queue queue() {
      // 是否持久化
      boolean durable = true;
      // 仅创建者可以使用的私有队列，断开后自动删除
      boolean exclusive = false;
      // 当所有消费客户端连接断开后，是否自动删除队列
      boolean autoDelete = false;
      return new Queue(QUEUE_NAME, durable, exclusive, autoDelete);
    }
  
    @Bean
    public TopicExchange exchange() {
      // 是否持久化
      boolean durable = true;
      // 当所有消费客户端连接断开后，是否自动删除队列
      boolean autoDelete = false;
      return new TopicExchange(QUEUE_EXCHANGE_NAME, durable, autoDelete);
    }
  
    @Bean
    public Binding binding(Queue queue, TopicExchange exchange) {
      return BindingBuilder.bind(queue).to(exchange).with(QUEUE_NAME);
    }
  }
  

• 编写sender消息发送功能类

  @Service
  public class Sender {
    @Autowired
    private AmqpTemplate rabbitTemplate;
  
    public void send() {
        System.out.println("ELSE 发送消息...");
        rabbitTemplate.convertAndSend(RabbitMQConfig.QUEUE_NAME, "你好， ELSE!");
    }
  }
  

• 编写amqp-sender测试类

  @RunWith(SpringRunner.class)
  @SpringBootTest
  public class AmqpSenderApplicationTests {
  
    @Autowired
    private Sender sender;
    @Test
    public void send() throws Exception {
      sender.send();
    }
  }
  

编写amqp-receiver

• 配置application.yml

  server:
    port: 8081
    tomcat:
      uri-encoding: UTF-8
  
  spring:
    rabbitmq:
      host: localhost
      port: 5672
      username: guest
      password: guest
  

• 编写amqp-receiver 配置类

  @Configuration
  public class RabbitMQConfig {
      public static final String QUEUE_NAME = "spring-boot";
  
       @Bean
       SimpleMessageListenerContainer container(ConnectionFactory connectionFactory,
                                         MessageListenerAdapter listenerAdapter) {
          SimpleMessageListenerContainer container = new SimpleMessageListenerContainer();
          container.setConnectionFactory(connectionFactory);
          container.setQueueNames(QUEUE_NAME);
          container.setMessageListener(listenerAdapter);
          return container;
      }
  
      @Bean
      MessageListenerAdapter listenerAdapter(Receiver receiver) {
          return new MessageListenerAdapter(receiver, "receiveMessage");
      }
  }
  

• 编写receiver消息接收功能类

  @Service
  public class Receiver {
  
    @RabbitListener(queues = RabbitMQConfig.QUEUE_NAME)
    public void receiveMessage(String message) {
        System.out.println("Received <" + message + ">");
    }
  }
