docker 中 rabbitmq 的 Spring 启动应用程序问题

Question

我正在尝试使用 rabbitmq 构建一个带有Spring云流的事件驱动微服务。就我而言，rabbitmq 正在 docker 中运行。

用于在容器下面运行的 Docker 命令

Docker run -d --主机名 my-rabbit --name some-rabbit --publish 15672：15672 Rabbitmq：3

然后进入容器的 bash 模式，我在以下命令下触发：rabbitmq-plugins 启用rabbitmq_management以启动管理插件

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                                                          NAMES
b2bc315c44aa        rabbitmq:3          "docker-entrypoint..."   7 minutes ago       Up 7 minutes        4369/tcp, 5671-5672/tcp, 25672/tcp, 0.0.0.0:15672->15672/tcp   some-rabbit

所以我可以从本地主机上的浏览器访问码头工人：15672

但是当我启动 Spring 启动应用程序时，它不会进行队列和交换。请检查堆栈跟踪。

提前谢谢。

Answer 1

我一直在努力使用在 docker 中运行的兔子 mq，我认为您需要在 spring boot application.properties 文件中创建一些条目以克服连接问题。

由于连接被拒绝，您的交易所似乎未创建。你需要克服这一点。在兔子 Web 管理控制台中，您需要创建一个具有权限的用户。然后在应用程序属性中添加一些配置：

spring.rabbitmq.port=5672
spring.rabbitmq.username=the_user_name
spring.rabbitmq.password=user_password

祝你好运。

您需要使用具有管理插件的 RabbitMQ 的 Docker 镜像（参见 https://hub.docker.com/_/rabbitmq/），在您的例子中是 rabbitmq：3-management。
