### 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`):

    <dependency>
      <groupId>io.vertx</groupId>
      <artifactId>vertx-config-spring-config-server</artifactId>
      <version>3.4.0</version>
    </dependency>
    <dependency>
      <groupId>io.vertx</groupId>
      <artifactId>vertx-config</artifactId>
      <version>3.4.0</version>
    </dependency>

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

    compile 'io.vertx:vertx-config:3.4.0'
    compile 'io.vertx:vertx-config-spring-config-server:3.4.0'

#### Configuring the store

Once added to your classpath or dependencies, you need to configure the `ConfigRetriever` to use this store:

    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)

- `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
