如果设置了spring.cloud.config.server.bootstrap=true，则需要使用复合配置

Question

问题：如何获取位置https://github.com/TEK-Leads/Config-Properties.git

的数据

当我尝试运行这个应用程序时，它没有显示任何结果，它只显示默认的通过结果（see. MessageController）。或 ConfigClient 端日志显示 这种按摩。

找不到 PropertySource：对“http://localhost:8888/application/default”的 GET 请求出现 I/O 错误：连接被拒绝；嵌套异常是 java.net.ConnectException: Connection denied

将 config-Server 端 application.yml 文件更改为 bootstrap.yml 时，在下面抛出异常。

If you are using the git profile, you need to set a Git URI in your configuration.  If you have set spring.cloud.config.server.bootstrap=true, you need to use a composite configuration.

Answer 1

尝试在pom.xml文件中添加依赖：

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency>

Answer 2

据记录 here，

如果你使用引导标志，配置服务器需要有它的 在 bootstrap.yml 中配置的名称和存储库 URI。

您没有发布引导文件，因此不清楚您是否已定义它们。如果没有，那可能是问题的根源，因为您已将 spring.cloud.config.server.bootstrap 设置为 true。在配置服务器的资源文件夹中的 bootstrap.properties 文件中，您需要定义以下属性：

配置服务器 bootstrap.properties

spring:
  cloud:
    config:
      server:
        git:
          uri: https://github.com/TEK-Leads/Config-Properties.git
          clone-on-start: true
        bootstrap: true
      enabled: true
   
  application:
    name: Config-Server

配置客户端 bootstrap.properties

spring:
  application:
    name: client-config
    
  cloud:
    config:
      uri: http://localhost:9090
  config:
    activate:
      on-profile:
        active:prod

还可能值得注意的是，自 Spring Boot 2.4 起，引导上下文初始化已被弃用，因此此设置不再需要使用引导。更多信息请访问https://docs.spring.io/spring-cloud-config/docs/current/reference/html/。
