=== Spring Config Server Store

The Spring Config Server Store extends the Vert.x Configuration Retriever and provides the
a way to retrieve configuration from a Spring Server.

==== Using the Spring Config Server Store

To use the Spring Config Server Store, add the following dependency to the
_dependencies_ section of your build descriptor:

* Maven (in your `pom.xml`):

[source,xml,subs="+attributes"]
----
<dependency>
 <groupId>io.vertx</groupId>
 <artifactId>vertx-config-spring-config-server</artifactId>
 <version>3.6.0.CR2</version>
</dependency>
<dependency>
 <groupId>io.vertx</groupId>
 <artifactId>vertx-config</artifactId>
 <version>3.6.0.CR2</version>
</dependency>
----

* Gradle (in your `build.gradle` file):

[source,groovy,subs="+attributes"]
----
compile 'io.vertx:vertx-config:3.6.0.CR2'
compile 'io.vertx:vertx-config-spring-config-server:3.6.0.CR2'
----

==== Configuring the store

Once added to your classpath or dependencies, you need to configure the
`link:../../yardoc/VertxConfig/ConfigRetriever.html[ConfigRetriever]` to use this store:

[source, ruby]
----
require 'vertx-config/config_retriever'
store = {
  'type' => "spring-config-server",
  'config' => {
    'url' => "http://localhost:8888/foo/development"
  }
}

retriever = VertxConfig::ConfigRetriever.create(vertx, {
  'stores' => [
    store
  ]
})

----


Configurable attributes are:

* `url` - the `url` to retrieve the configuration (mandatory), supports two type of formats:
** `/{application}/{environment}` which produces response with separated propertySources
** `/{application}-{environment}.json` which produces response as JSON with unique fields and resolved Spring placeholders
* `timeout` - the timeout (in milliseconds) to retrieve the configuration, 3000 by default
* `user` - the `user` (no authentication by default)
* `password` - the `password`
* `httpClientConfiguration` - the configuration of the underlying HTTP client
