运行config-client时遇到错误..简单的事情直接来自弹簧指南不起作用。

Answer 1

确保GIT URI有效，它应该是https://github.com/userName/repositoryName 然后将您的配置文件夹推送到repositoryName。

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

这里我有一个名为ConfigData的文件夹，我放置了所有的yml文件。你应该有一个带有config-client.yml文件的文件夹（yml文件名应该与你的应用程序名相同，因为你没有提到任何配置文件）在您的客户端yml文件中，它将使用您的应用程序名称回退到您的默认配置文件）

您的yml文件应如下所示

<强>配置-client.yml this.test = "<p>bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbgggggggggggggggggggggggggggggggggg</p>"

config-client.yml文件应该放在你的git repo中。

config-client的bootstrap.yml

--- message : Hello World!

注意：如果你提到profileName，那么yml文件名应为 config-client-profileName.yml

config.server的application.yml

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

进行此更改并尝试，希望它有用。

PS：如果您没有git帐户，请创建一个帐户，然后创建存储库

Answer 2

也许由

config-client的bootstrap.yml

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