spring cloud config searchPaths

问题

I'm looking at implementing the 12factor approach to externalising config via Spring Cloud Config but am not able to get the wildcards working using searchPaths as I expected.

The documentation http://cloud.spring.io/spring-cloud-config/spring-cloud-config.html#_spring_cloud_config_server mentions that wildcards {application}, {label}, {profile} can be used within the searchPaths variable so that "you can segregate the directories in the path, and choose a strategy that makes sense for you (e.g. sub-directory per application, or sub-directory per profile)."

I'm looking to have a single git repo, with either subdirectories per profile (and then per app, or subdirectory per app (then by profile).

e.g.

    spring:
      cloud:
        config:
          server:
            git:
              uri: https://stash.xxx.com.au/scm/xxx/config
              searchPaths: {application}
or
              searchPaths: {profile}
or
              searchPaths: {application}/{profile}

However when I use any of the wildcards {application} or {profile} in my searchPaths it doesn't find the data in the git repo, or for the concatenated option fails to startup at all.

Does anyone have a working example of this I can refer to? Cheers Roy

回答1:

Actually none of the examples in the user guide show the pattern being used in a list of searchPaths. I don't think that feature is supported with the GIT backend (but {application} is effectively the default in the filesystem backend, i.e. the one that works in the "native" profile).

回答2:

Use single quote and it works fine.

searchPaths: '{application}'

Hope this helps if someone stumbles across this problem.

In addition to above, and more importantly if you want your common configuration (e.g. application.yml) which is shared across multiple applications per environment, to be read. Then place application.yml in a folder (say - common), then the config goes like this:

searchPaths:
  - '{application}'
  - common

{application} resolves to the value of 'spring.application.name' in the config clients' bootstrap.yaml.
