SpringBoot2.x+rocketmq5.x整合服务
1 坑, 主要是各版本的依赖maven不一样,导致连接异常,找不到topic
2 JDK maven依赖和springboot start 依赖是不一样 下面是pom.xml
可以参考此处 文档, 还是官方文档靠谱消息队列 RocketMQ 版 Spring Boot Starter 使用-RocketMQ 5.x-文档中心-腾讯云
org.apache.rocketmq
rocketmq-spring-boot-starter
2.2.2
org.apache.rocketmq
rocketmq-client
org.apache.rocketmq
rocketmq-acl
org.apache.rocketmq
rocketmq-client
4.9.7
org.apache.rocketmq
rocketmq-acl
4.9.7
2 编写一个工具类发送消息
package cn.djrj.common.config;
import org.apache.rocketmq.client.producer.SendCallback;
import org.apache.rocketmq.client.producer.SendResult;
import org.springframework.messaging.Message;
import org.apache.rocketmq.spring.core.RocketMQTemplate;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;
import javax.annotation.Resource;

*/
@Component
public class RocketMqHelper {
/**
* 日志
*/
private static final Logger LOG = LoggerFactory.getLogger(RocketMqHelper.class);
/**
* rocketmq模板注入
*/
@Resource
private RocketMQTemplate rocketMQTemplate;
@PostConstruct
public void init() {
LOG.info("---RocketMq助手初始化---");
}
/**

}

}
/**

public void syncSendOrderly(Enum topic, Message message, String hashKey) {
syncSendOrderly(topic.name(), message, hashKey);
}
/**

}
};
}
@PreDestroy
public void destroy() {
LOG.info("---RocketMq助手注销---");
}
}
3 消费者类
package cn.djrj.common.config;
import lombok.extern.slf4j.Slf4j;
import org.apache.rocketmq.spring.annotation.RocketMQMessageListener;
import org.apache.rocketmq.spring.core.RocketMQListener;
import org.springframework.stereotype.Component;
/** 消费者
* @author lmc
* @Classname ConsumerMqListener
* @Description TODO
* @Date 2023/12/4 13:49
* @Created by lmc
*/
@Slf4j
@Component
@RocketMQMessageListener(topic = "TestTopic", consumerGroup = "${rocketmq.consumer.group}")
public class ConsumerMqListener implements RocketMQListener {
@Override
public void onMessage(String msg) {
// System.out.println("接收到消息，开始消费..msg: " + person.getName() + ",age:" + person.getAge());
log.info("接收到消息，开始消费...msg: " + msg);
}
}
4 配置文件, 消费者和生产者都需要加账号
#rocketmq配置
rocketmq:
name-server: rmq-cn.cn-hangzhou.rmq.aliyuncs.com:80
consumer:
group: Test_Group1
access-key: xxxxxx
secret-key: xxxxxx
# 生产者配置
producer:
access-key: xxxxx
secret-key: xxxxx
is-on-off: on
group: Test_Group1
# 发送同一类消息的设置为同一个group，保证唯一
# 服务地址
#namesrvAddr: rmq-cn.cn-hangzhou.rmq.aliyuncs.com:80
# 消息最大长度 默认1024*4(4M)
maxMessageSize: 4096
# 发送消息超时时间,默认3000
sendMsgTimeout: 3000
# 发送消息失败重试次数，默认2
retryTimesWhenSendFailed: 2测试方法, 测试类可以自定义发送
@Resource
RocketMqHelper rocketMqHelper;
@GetMapping("/send")
public AjaxResult sendMq() {
SysVersion version = new SysVersion();
version.setCode("2005");
version.setProgrammeName("产品名称");
version.setName("测试MQ");
rocketMqHelper.asyncSend("TestTopic", MessageBuilder.withPayload(version).build());
return AjaxResult.success(true);
}主要的坑, 版本必须对应,并且topic在消停队列存在, 分组必须要有
