RabbitMQ安装以及SpringBoot整合RabbitMQ

SpringBootMQ整合Rabbit

#拉取rabbitmq镜像
docker pull rabbitmq

#启动RabbitMQ
docker run -d --hostname my-rabbit --name rabbit -p 15672:15672 -p 5672:5672 rabbitmq

#安装图形化插件
#进入容器
docker exec -it 容器id /bin/bash
#安装插件
rabbitmq-plugins enable rabbitmq_management

注意：
你在操作图形化界面时，可能会出现该问题：Management API returned status code 500，如下图：

解决方案：

#进入rabbitmq容器，修改配置文件
docker exec -it 容器id /bin/bash
cd /etc/rabbitmq/conf.d/
echo management_agent.disable_metrics_collector = false > management_agent.disable_metrics_collector.conf
exit

运行成功后可以访问：localhost:15672 初始化账号和密码为：guest
远端服务器如果访问不到，注意是否忘记安全组设置开放端口

启动生产者，并发送消息：
发送请求：http://localhost:8081/topic/send


消费者监听到消息后消费消息：
