Spring 在 heroku 上部署时启动绑定到 cloudmaqp 错误

Question

我将一项服务部署到 heroku。我的服务使用 cloudamqp 作为云消息服务。当我在本地环境中的服务运行连接成功时，我从未发现此错误。

但是当我将服务部署到 heroku 时，出现了这个错误。

当我看到我的 rabbitmq 管理页面时，我的服务成功连接到我的 cloudamqp rabbitmq 服务器。像这样显示

谁能帮我解决这个问题。

Answer 1

禁用 rabbitmq 管理健康检查，我不知道它在做什么，但它导致了你的问题：

management.health.rabbit.enabled=false

https://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html

Answer 2

已修复，

忘记禁用 RabbitAutoConfiguration 导致我的服务连接 localhost:5672 messagebroker 服务器。

通过添加

修复了它

@EnableAutoConfiguration(exclude = {RabbitAutoConfiguration.class})

根据此页面 https://github.com/spring-cloud/spring-cloud-stream-binder-rabbit/blob/master/docs/src/main/asciidoc/overview.adoc，在 spring 云流应用程序上使用多个绑定器时禁用 RabbitAutoConfiguration 很重要。
