自动刷新在Spring Boot 2中不工作的配置客户端

Question

我正在尝试将一个简单的示例代码从Spring Cloud Config Server和RabbitMQ作为Spring Cloud Bus(基于Spring Boot 1.5.22.RELEASE和Spring Cloud Brixton.SR7(迁移到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、触发推送webhook，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中更新。在CCD_ 10和CCD_。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，或者我忘记配置了哪个属性？

这是我的配置/代码：

GitLab(作为Docker容器启动(Push WebHook：http://user:password@localhost:889/监视器

RabbitMQ(作为Docker容器启动(没有特定的配置

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

首先应该设置配置服务器名称(例如：spring.application.name= configServer(在配置服务器集中(例如：spring.cloud.bus.id = configServer:9000(，端口当然应该是配置服务器的端口
