代码

生产者发送消息

@RestController
@RequestMapping("/producer")
public class ProducerController {

    @Autowired
    private ProducerService producerService;

    // 发送同步消息
    @PostMapping("/sendSync")
    public Object sendSync(@RequestBody MessageReq req) {
        return producerService.sendSyncMessage(req.getTopic(), req.getTag(), req.getMessage());
    }

    // 发送异步消息
    @PostMapping("/sendAsync")
    public Object sendAsyncMessage(@RequestBody MessageReq req) {
        producerService.sendAsyncMessage(req.getTopic(), req.getTag(), req.getMessage());
        return "200";
    }
}

@Service
public class ProducerService {

    @Autowired
    private RocketMQTemplate rocketMQTemplate;

    /**
     * 发送同步消息.
     * @return 发送结果
     */
    public SendResult sendSyncMessage(String topic, String tag, String message) {
        // param1: topic和tag冒号分隔
        return rocketMQTemplate.syncSend(topic + ":" + tag, message);
    }

    /**
     * 发送异步消息.
     */
    public void sendAsyncMessage(String topic, String tag, String message) {
        rocketMQTemplate.convertAndSend(topic + ":" + tag, message);
    }
}

消费者

@Component
@RocketMQMessageListener(
        consumerGroup = "SimpleStringConsumerGroup",  // consumerGroup：消费者组名
        topic = "MQ_sp_test1",                         // topic：订阅的主题
        selectorExpression = "Tag-kk||Tag-kk2",         // selectorExpression, 1. 根据Tag过滤, 多个用||分割, 也可设置*; 2. 根据SQL92语法过滤
//        selectorExpression = "*",
//        selectorType = SelectorType.SQL92,             // 设置SQL92语法过滤, 不设置默认TAG
        messageModel = MessageModel.CLUSTERING,  // messageModel: 控制消息模式。MessageModel.CLUSTERING：负载均衡；MessageModel.BROADCASTING：广播模式
        consumeMode= ConsumeMode.CONCURRENTLY    // CONCURRENTLY: 无序消费; ORDERLY: 有序消费
)
public class SimpleConsumer implements RocketMQListener<String> {

    @Override
    public void onMessage(String message) {
        System.out.println("Received message : "+ message);
    }
}
