确保 GIT URI 是有效的，它应该是 https://github.com/userName/repositoryName 然后将配置文件夹推送到存储库名称。
示例：https://github.com/PraveenKumarMekala/Microservices-With-Spring-Example
在这里，我有一个名为ConfigData的文件夹，我在其中放置了所有yml文件。同样，您还应该有一个包含 config-client.yml 文件的文件夹(yml 文件名应与您的应用程序名称相同，因为您在客户端 yml 文件中没有提及任何配置文件，因此它将回退到您的应用程序名称的默认配置文件(
您的 yml 文件应如下所示
config-client.yml---
message : Hello World!
config-client.yml 文件应该放在你的 git 存储库中。

spring:

active: profileName
application:

注意：如果您提到配置文件名称，则yml文件名应为config-client-profileName.yml

做这个改变并尝试，希望它有用。
PS：如果您没有git帐户，请创建一个帐户，然后存储库

也许改变
