Spring Cloud Config + Spring Cloud Bus + RabbitMQ-無法使用本地Git存儲庫自動刷新客戶端

Question

我有一些應用程序從Spring Cloud Config Server（ Brixton.RELEASE ）獲取其配置，並希望啟用其屬性的自動刷新。 我已經按照Spring Cloud Config 文檔來配置服務器和客戶端應用程序，但是，在本地git文件上進行更改時，什么也沒有發生。

默認配置還可以檢測本地git存儲庫中的文件系統更改（在這種情況下不使用webhook，但是一旦您編輯配置文件，就會廣播刷新）。

誰能指出什么是錯誤的，或者在Spring Cloud的代碼中進行調試以進行檢查？

Answer 1

嘗試閱讀本文檔spring-cloud-config-push-notifications ，不要忘記安裝ngrock。 另外，如果您只需要刷新git commit，那么您甚至不需要cloud-bus項目，只需config就足夠了。 希望這可以幫助。

Answer 2

您將需要具有Spring Cloud Bus和RabbitMQ（或Kafka或Redis）支持的Config服務器。

...
<dependency>
  <groupId>org.springframework.cloud</groupId>
  <artifactId>spring-cloud-config-monitor</artifactId>
</dependency>
<dependency>
  <groupId>org.springframework.cloud</groupId>
  <artifactId>spring-cloud-starter-stream-rabbit</artifactId>
</dependency>
...

RabbitMQ與以下交換：

名稱 ：springCloudBus

類型 ：主題

耐用 ：正確

autoDelete ：假

內部 ：假

一旦Config服務器從Github，Bitbucket或GitLab中的任何一個接收到推送事件，就會通過Webhook到http：// <config-server> / monitor發送數據到主題。

以及具有Config和RabbitMQ庫的客戶端應用程序：

...
<dependency>
  <groupId>org.springframework.cloud</groupId>
  <artifactId>spring-cloud-starter-config</artifactId>
</dependency>
<dependency>
  <groupId>org.springframework.cloud</groupId>
  <artifactId>spring-cloud-starter-bus-amqp</artifactId>
</dependency>
...

訂閱上一個交換以接收具有需要刷新的屬性的消息。

您需要在pom.xml編譯中具有休閑依存關系（'org.springframework.cloud:spring-cloud-stream-binder-rabbit'）-如果在另一個系統中用Rabbitmq進行了軟管緩沖，則需要在其中指定宿主文件application.properties

spring.rabbitmq.host：{{hostname}}
