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 {
    @Autowired
    private 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 {
    @Autowired
    private 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CONCURRENTLY
        consumeMode = 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> {
    @Override
    public void onMessage(String s) {
        System.out.println(s);
    }
}
