Spring雲配置服務 - 客戶端不能正常工作

運行config-client時出現錯誤。直接從彈簧指南不起作用的簡單事情。從配置的客戶端服務Spring雲配置服務 - 客戶端不能正常工作

https://github.com/config-properties看起來並不像一個有效的資料庫。 – spencergibb

對不起忘了提，其有效，但已刪除完整路徑。該文件的內容與彈簧指南相同。 – Sandhya

什麼來自日誌？ – spencergibb

確保GIT URI有效，應該是https://github.com/userName/repositoryName 然後將配置文件夾推送到repositoryName。

例子：https://github.com/PraveenKumarMekala/Microservices-With-Spring-Example

這裏我有文件夾，名爲ConfigData，我把我所有的陽明files.Same方式，你也應該有配置-client.yml文件（YML文件名一個文件夾應該是相同的應用程序名，因爲你沒有提到在您的客戶端文件陽明海運任何配置文件，以便它會退回到您的默認配置文件與應用程序的名稱）

你YML文件應該如下

配置，client.yml --- message : Hello World!

config-client.yml文件應該放在你的git倉庫中。

bootstrap.yml配置客戶端的

--- spring: profiles: active: profileName application: name: config-client cloud: config: uri: http://localhost:8887 server: port: 8888

注：如果您提及PROFILENAME然後陽明的文件名應該是配置，客戶profileName.yml

application.yml的配置服務器

--- spring: cloud: config: server: git: uri:https://github.com/PraveenKumarMekala/Microservices-With-Spring-Example searchPaths: ConfigData # "native" is used when the native profile is active, for local tests with a classpath repo: native: searchLocations: classpath:offline-repository/ server: port: 8888

做這個改變和嘗試，希望它是有用的。

PS：如果你沒有git的賬號，創建一個帳戶，然後倉庫
