### 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-scala_2.12</artifactId>
      <version>3.5.0</version>
    </dependency>
    <dependency>
      <groupId>io.vertx</groupId>
      <artifactId>vertx-config</artifactId>
      <version>3.5.0</version>
    </dependency>

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

    compile 'io.vertx:vertx-config:3.5.0'
    compile 'io.vertx:vertx-config-spring-config-server-scala_2.12:3.5.0'

#### Configuring the store

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

    var store = ConfigStoreOptions()
      .setType("spring-config-server")
      .setConfig(new io.vertx.core.json.JsonObject().put("url", "http://localhost:8888/foo/development"))

    var retriever = ConfigRetriever.create(vertx, ConfigRetrieverOptions()
      .setStores(Set(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
