java - Spring Cloud 配置模式匹配不适用于 SVN

Question

我在为 Spring Cloud 配置服务器定义多个基于 svn 的配置存储库时遇到问题。我已经设置了三个配置存储库。一个用于开发、单元和生产。我已将默认设置设置为开发(通过设置 spring.cloud.config.server.svn.uri =development repo uri)。但是，每当我向配置服务器的 REST 端点发出 GET 请求时，无论我请求哪个配置文件，我总是会获取开发配置。请参阅下面的示例...

例如:

curl -i -X GET \
   -H "Content-Type:application/json" \
 'http://localhost:8888/my-service-accounts/unit' 

结果:

{
   "name":"my-service-accounts",
   "profiles":[
      "unit"
   ],
   "label":null,
   "version":"750",
   "propertySources":[
      {
         "name":"http://PATH_TO_MY_SVN_SERVER/config-repo-development/trunk/my-service-accounts.yml",
         "source":{
            "server.port":8080,
            "hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds":3000
         }
      }
   ]
}

但我预计...

{
   "name":"my-service-accounts",
   "profiles":[
      "unit"
   ],
   "label":null,
   "version":"750",
   "propertySources":[
      {
         "name":"http://PATH_TO_MY_SVN_SERVER/config-repo-unit/trunk/my-service-accounts.yml",
         "source":{
            "server.port":7777,
            "hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds":3000
         }
      }
   ]
} 

• 请注意 propertySources[0].name 值的差异。我希望此配置来自单元存储库，但它仍然来自开发存储库。

我的配置服务器配置:

application.yml

server:
  port: 8888
spring:
  profiles:
    include: subversion
  cloud:
    config:
      server:
        svn:
          username: configserver
          password: ************
          uri: http://PATH_TO_MY_SVN_SERVER/config-repo-development
          repos:
            development:
              pattern:  ["*/development"]
              uri: http://PATH_TO_MY_SVN_SERVER/config-repo-development
            unit:
              pattern: ["*/unit"] 
              uri: http://PATH_TO_MY_SVN_SERVER/config-repo-unit
            production:
              pattern:
                - '*/production'
              uri: http://PATH_TO_MY_SVN_SERVER/config-repo-production

      discovery:
        enabled: true
  application:
    name: my-server-config

• 注意:我的 IDE (IntelliJ) 警告我它无法解析 spring.cloud.config.server.svn.repos.*.uri 的配置属性...但这就是 Spring Cloud Config 的方式文档展示了如何指定存储库路径。

我最终重新组织了 svn 配置存储库的目录布局，并使用更灵活的“searchPaths”属性来实现我想要的功能。

新的 SVN 存储库布局:

• /svn/config/trunk/dev/service-name.yml
• /svn/config/trunk/prod/service-name.yml
• /svn/config/trunk/unit/service-name.yml

基本上，使用这种方法，您可以定义配置存储库 URI，然后定义一个 searchPaths 属性，该属性对传入路径进行模式匹配，以确定在哪个目录中搜索配置。

新的application.yml

server:
  port: 8888
spring:
  profiles:
    include: subversion
  cloud:
    config:
      server:
        svn:
          username: configserver
          password: ************
          uri: http://PATH_TO_MY_SVN_SERVER/svn/config
          searchPaths: ["{profile}"]
      discovery:
        enabled: true
  application:
    name: my-server-config

通过 HTTP 端点访问配置服务器:

curl -i -X GET \
   -H "Content-Type:application/json" \
 'http://localhost:8888/my-service-name/unit'

默认情况下的配置服务器似乎匹配

svn_server/{application-name}/{pattern_defined_in_searchPaths}

就我而言是:

svn_server/{application-name}/{profile}
