pom.xml

 <!--AMQP依赖，包含RabbitMQ--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-amqp</artifactId></dependency>

application.yaml

spring:rabbitmq:host: 127.0.0.1username: guestpassword: guestport: 5672virtual-host: test_vhostconnection-timeout: 600000# 关闭自动ack，设置成手动acklistener:simple:acknowledge-mode: manualprefetch: 10concurrency: 2max-concurrency: 5

配置文件，也可以使用@PostConstruct

@Configuration

消费者代码

@Component
@Slf4j
public class MessageListener  {@RabbitListener(queues="springboot_queue")public void process(Message message) {log.info("helloWorld模式 received message : {}",new String(message.getBody()));}}

生产者代码

	@Autowiredprivate RabbitTemplate rabbitTemplate;// pub/sub 发布订阅模式   交换机类型 fanout@GetMapping("/fanoutSend")public String fanoutSend() throws AmqpException, UnsupportedEncodingException {//fanout模式只往exchange里发送消息。分发到exchange下的所有queuerabbitMQService.sendMessage("my_topic_exchange","*","fanoutSend");return "message sended : "+message;}//topic 工作模式   交换机类型 topic@GetMapping("/topicSend")public String topicSend() throws AmqpException, UnsupportedEncodingException {//fanout模式只往exchange里发送消息。分发到exchange下的所有queuerabbitTemplate.convertAndSend("spring_topic_exchange","yuyang.test","sadedf");return "ok";}

手动ack

	@RabbitListener(queues = "springboot_queue")public void listenerQueue(Message message, Channel channel) throws IOException {log.info(new String(message.getBody()));channel.basicAck(message.getMessageProperties().getDeliveryTag(),false);}
