RocketMQ是一款开源的分布式消息系统，基于高可用分布式集群技术，提供低延时的、高可靠的消息发布与订阅服务

win10 + Spring Cloud Hoxton.SR9 + Spring Cloud Alibaba 2.2.6.RELEASE + RocketMQ 4.7.0

关于MQ与RocketMQ的环境搭建查看之前的文章

• MQ的适用场景、选择、术语和概念
• Windows下安装RocketMQ

• pom.xml

    org.apache.rocketmq
    rocketmq-spring-boot-starter
    2.1.1

• application.yml

rocketmq:
  name-server: 127.0.0.1:9876
  producer:
    group: producer-group

• TestRocketController.java

import lombok.RequiredArgsConstructor;
import org.apache.rocketmq.spring.core.RocketMQTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/rocketmq")
@RequiredArgsConstructor(onConstructor = @__(@Autowired))
public class TestRocketController {

    private final RocketMQTemplate rocketMQTemplate;

    @PostMapping("test")
    public String test() {
        rocketMQTemplate.convertAndSend(
                "test-msg",
                "突然活得潦草了。。。");

        return "success";
    }

}

• RocketMQ控制台查看http://localhost:8088/#/message

• 消息详情

• pom.xml

    org.apache.rocketmq
    rocketmq-spring-boot-starter
    2.1.1

• application.yml

rocketmq:
  name-server: 127.0.0.1:9876

• TestRocketConsumer.java

import lombok.extern.slf4j.Slf4j;
import org.apache.rocketmq.spring.annotation.RocketMQMessageListener;
import org.apache.rocketmq.spring.core.RocketMQListener;
import org.springframework.stereotype.Service;

@Service
@Slf4j
@RocketMQMessageListener(consumerGroup = "consumer-group", topic = "test-msg")
public class TestRocketConsumer implements RocketMQListener {
    @Override
    public void onMessage(String str) {
        // TODO 业务处理
        log.info("监听到主题为'test-msg'的消息：" + str);
    }
}
