启动类

package jkw;import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;@Slf4j
@SpringBootApplication
public class Main8009 {public static void main(String[] args) {SpringApplication.run(Main8009.class, args);log.info("************** 服务提供者 8009 启动成功 ************");}
}

RocketMQ SpringBoot 3.0不兼容解决方案

我们要在resources文件夹中，新建META-INF/spring文件夹，在里面新建一个叫 org.springframework.boot.autoconfigure.AutoConfiguration.imports 的文件里面填入 org.apache.rocketmq.spring.autoconfigure.RocketMQAutoConfiguration

创建topic

mqadmin updateTopic -n localhost:9876 -c DefaultCluster -t testtopic

生产者服务

package jkw.service;import org.apache.rocketmq.client.producer.SendResult;
import org.apache.rocketmq.spring.core.RocketMQTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Service;
@Service
public class MessageProduce {@Autowiredprivate RocketMQTemplate rocketMQTemplate; // 直接注入生产者@Value("${demo.rocketmq.topic}")private String topic;/*** 发送消息** @param message* @return*/public SendResult sendMessage(String message) {return rocketMQTemplate.syncSend(topic, message);}
}

生产者控制器

package jkw.controller;import jkw.service.MessageProduce;
import org.apache.rocketmq.client.producer.SendResult;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class RocketmqProduceCon {@Autowiredprivate MessageProduce messageProduce;/*** 发送消息** @param message* @return*/@GetMapping("/send")public SendResult sendMessage(String message) {return messageProduce.sendMessage(message);}
}

消费者服务

package jkw.service;import org.apache.rocketmq.spring.annotation.ConsumeMode;
import org.apache.rocketmq.spring.annotation.MessageModel;
import org.apache.rocketmq.spring.annotation.RocketMQMessageListener;
import org.apache.rocketmq.spring.annotation.SelectorType;
import org.apache.rocketmq.spring.core.RocketMQListener;
import org.springframework.stereotype.Service;/*** 消费者主要使用RocketMQMessageListener接口进行监听配置*/
@Service
@RocketMQMessageListener(//主题topic = "${demo.rocketmq.topic}",//消费组consumerGroup = "${demo.rocketmq.consumer}",// 过滤方式：默认为Tag过滤selectorType = SelectorType.TAG,// 过滤值：默认为全部消费，不过滤【*】selectorExpression = "*",// 消费模式：顺序消费ORDERLY，并发消费CONCURRENTLYconsumeMode = ConsumeMode.ORDERLY,// 消息模式：有集群消费CLUSTERING,广播消费messageModel = MessageModel.CLUSTERING)
public class MessageConsumer implements RocketMQListener<String> {@Overridepublic void onMessage(String s) {System.out.println(s);}
}
