springboot整合rabbitmq

maven依賴:

  <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-amqp</artifactId>
        </dependency>````
##配置：
配置隊列、交換器、隊列綁定、消息監聽容器等

@Configuration
public class RabbitmqConfig {
    @Autowired
    Environment          environment;
    private final String name = "helloworld";

    @Bean
    Queue queue() {
        return new Queue(name, false);
    }

    @Bean
    DirectExchange exchange() {
        return new DirectExchange("hello-exchange");
    }

    @Bean
    Binding binding(Queue queue, DirectExchange exchange) {
        return BindingBuilder.bind(queue).to(exchange).withQueueName();
    }

    @Bean
    SimpleMessageListenerContainer simpleMessageListenerContainer(MessageListenerAdapter listenerAdapter,
                                                                  @Qualifier("simpleConnectionFactory") ConnectionFactory connectionFactory) {
        SimpleMessageListenerContainer container = new SimpleMessageListenerContainer();
        container.setMessageListener(listenerAdapter);
        container.setConnectionFactory(connectionFactory);
        container.setQueueNames(name);
        return container;
    }

    @Bean(name = "simpleConnectionFactory")
    ConnectionFactory connectionFactory() {
        CachingConnectionFactory connectionFactory = new CachingConnectionFactory();
        connectionFactory.setAddresses(environment.getProperty("rabbitmq.addresses"));
        connectionFactory.setUsername(environment.getProperty("rabbitmq.username"));
        connectionFactory.setPassword(environment.getProperty("rabbitmq.password"));
        connectionFactory.setVirtualHost(environment.getProperty("rabbitmq.vhost"));
        connectionFactory.setPublisherConfirms(true);
        return connectionFactory;
    }

    @Bean
    Receiver receiver() {
        return new Receiver();
    }

    @Bean
    MessageListenerAdapter listenerAdapter(Receiver receiver) {
        return new MessageListenerAdapter(receiver, "processMessage");
    }

    @Bean(name = "myRabbitTemplate")
    RabbitTemplate rabbitTemplate(ConnectionFactory connectionFactory) {
        return new RabbitTemplate(connectionFactory);
    }
}```
##消息接受處理

**

• Created by Torres on 17/1/21.
  */
  public class Receiver {
  private CountDownLatch countDownLatch = new CountDownLatch(1);

  public void processMessage(String message) {
  System.out.println(new Date() + "receive message is:" + message);
  countDownLatch.countDown();
  }

  public CountDownLatch getCountDownLatch() {
  return countDownLatch;
  }
  }```

消息發送:

這里使用定時任務每個五秒發送message.

/**
 * Created by Torres on 17/1/21.
 */
@EnableScheduling
//任務調度
@Component
public class Worker {
    @Autowired
    @Qualifier("myRabbitTemplate")
    RabbitTemplate rabbitTemplate;

    @Scheduled(fixedDelay = 5000)
    public void sendMessage() {
        rabbitTemplate.convertAndSend("helloworld", "hello");
    }
}```
