主要是公司为了高可用方案 使用的是阿里云的RocketMQ 5.x版

公司用的spring cloud alibaba 那一套 架构

不过阿里云的mq不会自动创建 topic和group 需要在控制台手动创建 不然会报错

下面配置中的实例账户密码需要在这里查看

首先在项目中引入

 <rocketmq-version>2.3.0</rocketmq-version>
 
 <!-- rocketmq-spring-boot-starter -->
            <dependency>
                <groupId>org.apache.rocketmq</groupId>
                <artifactId>rocketmq-spring-boot-starter</artifactId>
                <version>${rocketmq-version}</version>
                <exclusions>
                    <exclusion>
                        <artifactId>fastjson</artifactId>
                        <groupId>com.alibaba</groupId>
                    </exclusion>
                    <exclusion>
                        <artifactId>slf4j-api</artifactId>
                        <groupId>org.slf4j</groupId>
                    </exclusion>
                </exclusions>
            </dependency>

nacos配置：

rocketmq:
#如果使用当前Demo访问阿里云RocketMQ 4.0系列实例，接入点应该是类似这样的格式  http://MQ_INST_XXX:xxx，注意！！！一定要有http协议头
#如果使用当前Demo访问阿里云RocketMQ 5.0系列实例，接入点应该是类似这样的格式  rmq-cn-xxx.xx:xxx，注意！！！一定不要自己添加http协议头
  name-server: z9x07.cn-hangzhou.rmq.aliyuncs.com:8080
  consumer:
   #如果使用阿里云RocketMQ 5.0系列实例，请设置实例详情页获取的实例用户名，不要设置阿里云账号的AccessKeyId。
   access-key: L6JJ6Yy2xxx
   #如果使用阿里云RocketMQ 5.0系列实例，请设置实例详情页获取的实例密码，不要设置阿里云账号的AccessKeySecret。
   secret-key: 582F4nF1xx
   # 注意，4.0实例需要在控制台实例详情中查看是否有命名空间，无命名空间则不需要填写此项
   instance-name: rmq-cn-x0r37
  producer:
   #如果使用阿里云RocketMQ 5.0系列实例，请设置实例详情页获取的实例用户名，不要设置阿里云账号的AccessKeyId。
   access-key: L6JJ6Yy2xxx
   #如果使用阿里云RocketMQ 5.0系列实例，请设置实例详情页获取的实例密码，不要设置阿里云账号的AccessKeySecret。
   secret-key: 582F4nF1xx
