RabbitMQ与SpringBoot 集成

咔咔皮卡丘 / 2023-08-17 / 原文

1、添加依赖

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-amqp</artifactId>
</dependency>

2、添加配置

官方配置https://docs.spring.io/spring-boot/docs/current-SNAPSHOT/reference/htmlsingle

spring.rabbitmq.host=localhost
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
spring.rabbitmq.virtual-host=/

3、guest用户默认是不支持远程连接的

操作：在/usr/local/rabbitmq/etc/rabbitmq下创建rabbitmq.conf

并写入[{rabbit, [{loopback_users, []}]}].

重启rabbitmq

4、简单例子（direct模式）

4.1、ioc注入

@Configuration
public class MQConfig {

    public static final String QUEUE = "queue";

    @Bean
    public Queue queue() {
        return new Queue(QUEUE, true);
    }
}

4.2、发送者

@Service
public class MQSender {

    private Logger logger = LoggerFactory.getLogger(getClass());

    @Autowired
    private AmqpTemplate amqpTemplate;

    public void send(String message){

        logger.info("send message:{}",message);

        amqpTemplate.convertAndSend(MQConfig.QUEUE,message);
    }

}

4.3、接收者

@Service
public class MQReceiver {

    private Logger logger = LoggerFactory.getLogger(getClass());

    @RabbitListener(queues = MQConfig.QUEUE)
    public void receiver(String message){
        logger.info("receiver message:{}",message);
    }
}
