=== 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>3.4.2</version>
</dependency>
<dependency>
  <groupId>io.vertx</groupId>
  <artifactId>vertx-config</artifactId>
  <version>3.4.2</version>
</dependency>
----

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

[source,groovy,subs="+attributes"]
----
compile 'io.vertx:vertx-config:3.4.2'
compile 'io.vertx:vertx-config-spring-config-server:3.4.2'
----

==== Configuring the store

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

[source, java]
----
ConfigStoreOptions store = new ConfigStoreOptions()
    .setType("spring-config-server")
    .setConfig(new JsonObject().put("url", "http://localhost:8888/foo/development"));

ConfigRetriever retriever = ConfigRetriever.create(vertx,
    new ConfigRetrieverOptions().addStore(store));
----


Configurable attributes are:

* `url` - the `url` to retrieve the configuration (mandatory)
* `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
