SpringBoot异步消息队列RabbitMQ的@EnableRabbit&@RabbitListener注解的使用

一、@EnableRabbit的使用

开启基于注解的RabbitMQ模式

@EnableRabbit//开启基于注解的RabbitMQ模式
@SpringBootApplication
public class AmqptestApplication {
 
    public static void main(String[] args) {
        SpringApplication.run(AmqptestApplication.class, args);
    }
 
}

二、@RabbitListene的使用

监听获取消息队列中的消息

@Service
public class BookService {
    /**
     * 只获取消息体
     * @param book
     */
    @RabbitListener(queues = "zhq.news")
    public void receive(Book book){
        System.out.println("收到消息："+book);
    }
 
    /**
     * 获取消息体和消息头
     * @param message
     */
    @RabbitListener(queues = "zhq")
    public void receiveWithMessage(Message message){
        System.out.println("Message:"+message);
        System.out.println("Body:"+message.getBody());
        System.out.println("MessageProperties:"+message.getMessageProperties());
 
    }
 
}

三、编写单元测试

@Autowired
    RabbitTemplate rabbitTemplate;
 
    @Test
    public void contextLoads() {
        rabbitTemplate.convertAndSend("exchange.direct","zhq",new Book("Java从入门到放弃","汤姆"));
    }
