spring boot学习第二十三篇：Spring Boot集成RocketMQ

前置条件先安装好RocketMQ

希望在Window10安装rocketMQ并简单使用，可以参考如下文章：

Window10安装rocketMQ并简单使用-CSDN博客

1、pom.xml文件里面加上依赖

<dependency>
            <groupId>org.apache.rocketmq</groupId>
            <artifactId>rocketmq-spring-boot-starter</artifactId>
            <version>2.2.3</version>
        </dependency>

pom.xml全文如下：

            </plugin>
        </plugins>
    </build>

</project>

2、application.yml配置文件需要加上如下配置：

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

该配置文件全部内容如下：

server:
  port: 8081
  servlet.context-path: /hmblogs

#配置数据源
spring:
  datasource:
    druid:
      db-type: com.alibaba.druid.pool.DruidDataSource
      driverClassName: net.sf.log4jdbc.sql.jdbcapi.DriverSpy
      url: jdbc:log4jdbc:mysql://${DB_HOST:localhost}:${DB_PORT:3306}/${DB_NAME:hmblogs}?useSSL=true&allowPublicKeyRetrieval=true&serverTimezone=UTC
      username: ${DB_USER:root}
      password: ${DB_PWD:demo}
  redis:
    host: localhost
    port: 6379
    password: heming
    database: 10
#  data:
#    mongodb:
#      host: 43.138.0.199
#      port: 27017
#      username: hmblogs
#      password: demo
#      database: hmblogs
#      authentication-database: admin
  servlet:
    multipart:
      max-file-size: 10MB
      max-request-size: 10MB
  #minio配置
  minio:
    access-key: Irr1hKVWRacP91HAqJ60
    secret-key: demo
    url: http://localhost:9000  #访问地址
    bucket-name: hmblogs-bucket

es:
  host: 43.138.0.199
  port: 9200
  scheme: http
  user: elastic
  password: demo

captcha:
  width: 200
  height: 100

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

3、生产者代码如下：

package com.hmblogs.backend.controller;


import lombok.extern.slf4j.Slf4j;
import org.apache.rocketmq.spring.core.RocketMQTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/mq")
@Slf4j
public class MqProducerController {
    @Autowired
    private RocketMQTemplate rocketMQTemplate;


    @RequestMapping("/producer")
    public String producer(@RequestParam("msg") String msg){
        log.info("我要发消息："+msg);
        rocketMQTemplate.convertAndSend("first-topic","你好" + msg);
        return "connected";
    }
}

4、消费者代码如下：

package com.hmblogs.backend.util;


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

@Component
@RocketMQMessageListener(topic = "first-topic", consumerGroup = "superman-consumer-group")
@Slf4j
public class MqConsumer implements RocketMQListener<String> {
    @Override
    public void onMessage(String message) {
        log.info("我的RocketMQ接收到的消息为："+message);
        //在此处添加自己要加的逻辑
    }
}

5、调用生产者的生产消息接口

查看日志，发现打印的日志符合预期

调用生产者的生产消息接口，msg参数换一下
