type Provider ¶

type Provider func(optional bool, source string) (map[string]string, error)

Provider defines a function type that provides configuration data from a specific source.

If access to a remote server is needed, the information required to access it is usually placed in the source string or passed through environment variables.

To support dynamic refresh, a version number field can be added and a regular Bean can be registered to listen for changes. When the version changes, the configuration can be updated.
