生产者发送消息
@RestController

public class ProducerController {@Autowiredprivate 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 {@Autowiredprivate 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TAGmessageModel = 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> {@Overridepublic void onMessage(String message) {System.out.println("Received message : "+ message);}
}
测试
同步消息
异步消息
TAG过滤消息
1. 消费者指定了TAG, 不满足的不会消费, 状态是CONSUMED_BUT_FILTERED
