配置文件的 Spring Cloud 配置模式匹配

Question

我正在尝试根据应用程序的不同配置文件实现 Spring Cloud 配置的模式匹配功能。基于 http://cloud.spring.io/spring-cloud-config/spring-cloud-config.html#_environment_repository 中的文档可以根据配置文件匹配存储库。下面是我的配置服务器 application.yml

server:
  port: 8888
spring:
  cloud:
    config:
      server:
        git:
          uri: ssh://xxxx@github/sample/cloud-config-properties.git
          repos:
            development:
             pattern:
               -*/development    
               -*/staging 
             uri: ssh://<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="44232d30043c3c3c232d302c31266a272b29" rel="noreferrer noopener nofollow">[email protected]</a>/development.git
            test:
             pattern: 
               -*/test
               -*/perf
             uri: ${HOME}/Documents/cloud-config-sample-test

我有一个配置客户端应用程序“user”，并且有 user.properties、user-development.properties、user-test.properties

根据文档 - 无论应用程序名称如何，如果模式匹配 */development 即 localhost:8888/user/development 或 localhost:8888/demo/development 我的配置服务器应该匹配配置文件模式并获取适当的属性。 例如:http://localhost:8888/demo/development 我应该从 ssh://[email protected] 获取 demo-development.properties/development.git

但在我的应用程序中，默认 uri 用于所有配置文件，即我的属性文件 demo.properties 是从返回的 uri:ssh://xxxx@github/sample/cloud-config-properties.git

对此有任何指示吗？

编辑: pom.xml

Answer 1

对 PatternMatching 源代码进行一些调试后，我解决了这个问题:您可以选择两种方法之一。

application.yml
server:
  port: 8888
spring:
  cloud:
    config:
      server:
        git:
          uri: ssh://xxxx@github/sample/cloud-config-properties.git
          repos:
           development:
            pattern: '*/development' ## give in quotes
            uri: ssh://<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="86e1eff2c6fefefee1eff2eef3e4a8e5e9eb" rel="noreferrer noopener nofollow">[email protected]</a>/development.git

或者

development:
  pattern: xx*/development,*/development ##since it is not allowed to have a value starting with a wildcard( '*' )after pattern I first gave a generic matching but the second value is */development. Since pattern takes multiple values, the second pattern will match with the profile
  uri: ssh://<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="0e69677a4e76767669677a667b6c206d6163" rel="noreferrer noopener nofollow">[email protected]</a>/development.git

模式:*/development.yml 文件上出现错误 - 预期是字母或数字字符，但找到了/。

未识别配置文件模式 git repo 的原因是:虽然 spring 允许 yml 文件中以“-”开头的模式有多个数组值，但模式匹配器将“-”作为要匹配的字符串。即它正在寻找模式 '-*/development' 而不是 '*/development'。

   repos:
    development:
     pattern:
      -*/development    
      -*/staging 

我观察到的另一个问题是，如果我必须将模式数组提及为 '- */development' - 请注意连字符后的空格(这意味着表明它可以将多个值作为数组保存)并以 '*/development' 开头，并出现错误:预期的字母或数字字符，但找到了/

 repos:
        development:
         pattern:
          - */development    
          - */staging
