本文介绍了弹簧云配置模式匹配配置文件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试基于应用程序的不同配置文件来实现spring cloud config的模式匹配功能。基于 http：//cloud.spring中的文档。 io / spring-cloud-config / spring-cloud-config.html＃_environment_repository ，可以根据配置文件匹配存储库。以下是我的配置服务器application.yml

 服务器：
端口：8888 
春季：
云：
配置：
服务器：
 git：
 uri：ssh：//xxxx@github/sample/cloud-config-properties.git 
仓库： 
开发：
模式：
-* /开发
-* / staging 
 uri：ssh：//git@xxxgithub.com/development.git 
测试：
模式：
-* /测试
-* / perf 
 uri：$ {HOME} / Documents / cloud-config-sample-test

我有一个配置客户端应用程序 user，并且具有user.properties，user-development.properties，user-test.properties

根据文档-与应用程序名称无关，如果模式匹配* / development即localhost：8888 / user / development或localhost：8888 / demo /开发我的配置服务器应该与配置文件模式匹配并获取适当的属性。
例如： http：// localhost：8888 / demo / development
我应该从ssh：//git@xxxgithub.com/development.git

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

任何指向

解决方案

在对PatternMatching源代码进行一些调试之后，这里是我解决了这个问题：您可以选择以下两种方式之一。

  application.yml 
服务器：
端口：8888 
春季：
云：
配置：
服务器：
 git：
 uri：ssh：// xxxx @ github / sample / cloud-config-properties.git 
仓库：
开发：
模式：'* / development'##引用
 uri：ssh：//git@xxxgithub.com /development.git

 开发：
模式：xx * / development，* / development ##，因为在该模式之后，我首先给出了一个以通配符（'*'）开头的值，通用匹配，但第二个值为* / development。由于模式采用多个值，因此第二个模式将与配置文件
 uri匹配：ssh：//git@xxxgithub.com/development.git

模式：* /development。yml文件错误-预期为字母或数字字符，但找到但找到了/。

无法识别概要文件模式git repo的原因是：尽管spring在yml文件中允许模式以'-'开头的多个数组值，但模式匹配器将'-'作为要匹配的字符串。也就是说，它正在寻找'-* /开发'而不是'* / development 的模式。

 回购：
开发：
模式：
-* /开发
 -* / staging

我观察到的另一个问题是，如果我在yml文件上遇到编译错误必须将模式数组提到为'-* / development'-在连字符后注意空格（这表示它可以将多个值作为数组保存）并以'* / development'，有错误：预期的字母或数字字符，但找到但找到/

 回购：
开发：
模式：
-* /开发
-* /分段

I am trying to implement the pattern matching feature of spring cloud config based on the different profiles for an application. Based on the documentation in http://cloud.spring.io/spring-cloud-config/spring-cloud-config.html#_environment_repository it is possible to match the repositories based on profiles. Below is my config server 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://git@xxxgithub.com/development.git
            test:
             pattern: 
               -*/test
               -*/perf
             uri: ${HOME}/Documents/cloud-config-sample-test

I have an config client application "user" and have user.properties, user-development.properties, user-test.properties



Based on the documentation - irrespective of the application name , if the pattern matches */development i,e localhost:8888/user/development or localhost:8888/demo/development my config server should match the profile pattern and fetch the appropriate properties.
Ex: http://localhost:8888/demo/development
I should get demo-development.properties from ssh://git@xxxgithub.com/development.git

But in my application, the default uri is used for all the profiles i.e my property file demo.properties is returned from 
uri: ssh://xxxx@github/sample/cloud-config-properties.git

Any pointers on this?

 解决方案 
after some debugging  on the PatternMatching source code here is how I resolved the issue: You can choose one of the two ways.
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://git@xxxgithub.com/development.git
OR
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://git@xxxgithub.com/development.git
pattern: */development.Error on yml file- expected alphabetic or numeric character, but found but found /.

The reason the profile pattern git repo was not identified because : although spring allows multiple array values for pattern beginning with a '-' in the yml file, the pattern matcher was taking the '-' as string to be matched. i.e it is looking for a pattern '-*/development' instead of '*/development'. 
   repos:
    development:
     pattern:
      -*/development    
      -*/staging 
Another issue i observed was, I was getting a compilation error on yml file if i had to mention the pattern array as '- */development' - note space after hyphen(which is meant to show that it can hold multiple values as array) and start with a '*/development' with an error: expected alphabetic or numeric character, but found but found /
 repos:
        development:
         pattern:
          - */development    
          - */staging
