第一步：引入rocketMq相关依赖

<!--RocketMQ相关-->
<dependency>
    <groupId>org.apache.rocketmq</groupId>
    <artifactId>rocketmq-spring-boot-starter</artifactId>
</dependency>
<dependency>
    <groupId>org.apache.rocketmq</groupId>
    <artifactId>rocketmq-client</artifactId>
</dependency>

第二步：相关配置

#服务器地址
rocketmq.name-server=192.168.31.81:9876
//组名
rocketmq.producer.group=tanhua

发送消息的代码：示例

首先使用@Autowired注入RocketMQTemplate（后面直接使用，就不特殊说明）

@Autowired
private RocketMQTemplate rocketMQTemplate;

 private Boolean sendMsg(String publishId, Integer type) {
        try {
            User user = UserThreadLocal.get();

            Publish publish = this.quanZiApi.queryPublishById(publishId);

            //构建消息
            Map<String, Object> msg = new HashMap<>();
            msg.put("userId", user.getId());
            msg.put("date", System.currentTimeMillis());
            msg.put("publishId", publishId);
            msg.put("pid", publish.getPid());
            msg.put("type", type);

            this.rocketMQTemplate.convertAndSend("tanhua-quanzi", msg);//重点，tanhua-quanzi是主题，msg是消息
        } catch (Exception e) {
            log.error("发送消息失败! publishId = " + publishId + ", type = " + type, e);
            return false;
        }

收消息

RocketMQ相关配置

#服务器地址
rocketmq.name-server=192.168.31.81:9876
rocketmq.producer.group=tanhua

首先在类上面加注解
@RocketMQMessageListener(topic = “tanhua-quanzi”,consumerGroup = “tanhua-quanzi-consumer”)
类要实现
public class QuanZiMsgConsumer implements RocketMQListener
示例代码
先拿到数据进行分析
然后将数据存放到mogodb中

//发送消息传的值为String msg
@RocketMQMessageListener(topic = “tanhua-quanzi”,consumerGroup = “tanhua-quanzi-consumer”)
public class QuanZiMsgConsumer implements RocketMQListener{
//msg就是消息数据
public void onMessage(String msg) {
        
        try {
            //转化为json
            JSONObject jsonObject = JSONUtil.parseObj(msg);

           
    }
}}
