[英]Automatic refresh of Config Clients not working in Spring Boot 2
I am trying to migrate a simple example code with Spring Cloud Config Server
and RabbitMQ
as Spring Cloud Bus
(based on Spring Boot 1.5.22.RELEASE
and Spring Cloud Brixton.SR7
) to Spring Boot 2.2.6.RELEASE
and Spring Cloud Hoxton.SR3
。 该示例由配置服务器、配置客户端、作为 SCM 的GitLab
和RabbitMQ
(3.8 - Erlang 22.15) 组成。 代码正在编译,启动,push webhook被触发,也可以在服务端和客户端的日志中看到。
问题是Git中更新的属性在客户端没有更新。 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
,则该属性将被更新。
可能是什么问题或我忘记配置哪个属性?
这是我的配置/代码:
GitLab(启动为 Docker 容器) Push WebHook: http://user:password@localhost:8889/monitor
RabbitMQ(以Docker容器启动)无特殊配置

public void printProperty() {
System.out.println("Value of property \"myProperty\": " + myProperty);
}
}
提前谢谢了
在bootstrap.properties
中设置属性spring.cloud.bus.id
修复了问题: https://github.com/spring-cloud/spring-cloud-bus/issues/124#issuecomment-423960553
不是很漂亮,但它有效。
首先,您应该设置您的配置服务器名称(例如: spring.application.name= configServer
)和配置服务器集(例如: spring.cloud.bus.id = configServer:9000
)当然端口应该是您的配置服务器的端口。
