springcloud 配置檔案管理動態重新整理
摘要：
當修改一個配置檔案，我們需要重新打包專案或重新啟動服務才能生效，springcloud的config實現了配置檔案的統一管理，當配置檔案修改後提交Git後系統會自動重新整理獲取修改後的配置檔案。

當修改一個配置檔案，我們需要重新打包專案或重新啟動服務才能生效，springcloud的config實現了配置檔案的統一管理，當配置檔案修改後提交Git後系統會自動重新整理獲取修改後的配置檔案。
ofollow,noindex">eureka叢集搭建
- 將配置檔案上傳至Git上
新建一個maven專案：
建好的專案結構如下：
- pom檔案相關依賴

- 啟動檔案
@EnableDiscoveryClient
@SpringBootApplication
@EnableConfigServer
public class ConfigServerApplication {
public static void main(String[] args) {
SpringApplication.run(ConfigServerApplication.class, args);
}
}
複製程式碼
- 伺服器端配置檔案詳情
server.port=8081 spring.cloud.config.server.git.uri=https://github.com/castanea-kang/config-repo.git spring.cloud.config.server.git.searchPaths=cloud-config-repo spring.application.name=cloud-config spring.cloud.config.discovery.enabled=true spring.cloud.config.discovery.service-id=cloud-config spring.rabbitmq.host=114.115.243.135 spring.rabbitmq.port=5672 spring.rabbitmq.username=guest spring.rabbitmq.password=guest eureka.client.serviceUrl.defaultZone=http://eureka01:8080/eureka/ #eureka.instance.prefer-ip-address=true #eureka.instance.ip-address=114.115.243.135#配置從eureka註冊中心訪問介面的ip #eureka.instance.status-page-url-path=/cloud-config/test/#介面訪問路徑 management.security.enabled=false#是否開啟安全認證 複製程式碼
- 啟動config server端可以再eureka註冊中心找到該服務，如下圖：
可以通過訪問地址http://114.115.243.135:8081/cloud-config/test/ 得到資料：

- 配置檔案詳情bootstrap.properties

- 利用git的webhook實現實時更新通知，當向git進行事件操作時，進行配置檔案重新整理應用。
注：如果出現配置正常重新整理日誌列印正常，但是並沒有重新整理，在config client 控制層上加上註解
