自动刷新配置客户端在 Spring Boot 2 中不起作用

Question

我正在尝试将 Spring Cloud Config Server 和 RabbitMQ 的简单示例代码迁移为 Spring Cloud Bus（基于 Spring Boot 1.5.22.RELEASE 和 Spring Cloud Brixton.SR7）到 Spring Boot 2.2.6.RELEASE 和 Spring Cloud Hoxton.SR3。该示例由配置服务器、配置客户端、GitLab 作为 SCM 和 RabbitMQ(3.8 - Erlang 22.1.5) 组成。代码正在编译、启动、推送 webhook 被触发，也可以在服务器和客户端的日志中看到。

问题是在Git中更新的属性没有在客户端更新。在 Spring Boot 1.5.22.RELEASE 和 Spring Cloud Brixton.SR7 的基础上，它工作可靠。但是如果我手动执行 curl -X POST http://localhost:8889/actuator/bus-refresh，属性将被更新。

可能是什么问题或者我忘记配置哪个属性？

这是我的 configuration/code:

Git实验室（作为 Docker 容器启动） 推送 WebHook：http://user:password@localhost:8889/monitor

RabbitMQ（作为 Docker 容器启动） 无特殊配置

非常感谢

Answer 1

在 bootstrap.properties 中设置属性 spring.cloud.bus.id 解决了问题： https://github.com/spring-cloud/spring-cloud-bus/issues/124#issuecomment-423960553

不是很漂亮，但很管用。

Answer 2

首先你应该设置你的配置服务器名称（例如：spring.application.name= configServer）在配置服务器集（示例：spring.cloud.bus.id = configServer:9000）中，端口当然应该是您的配置服务器的端口。
