2.YAML File configuration

user:
  name: Jim
  age: 20
  birth: 2012-10-21
  sex: 1

server:
  port: 8000

3. Start loading profile , And into the config In the middle

public class ConfigApplication {

  public static void main(String[] args) {
    Vertx vertx = Vertx.vertx();
    ConfigRetriever retriever = readYaml(vertx);

    retriever.getConfig(json -> {
      DeploymentOptions options = new DeploymentOptions().setConfig(json.result());
      vertx.deployVerticle(MainApp.class.getName(), options);
    });
  }

  private static ConfigRetriever readYaml(Vertx vertx) {
    ConfigStoreOptions store = new ConfigStoreOptions()
        .setType("file")
        .setFormat("yaml")
        .setOptional(true)
        .setConfig(new JsonObject().put("path", "application.yaml"));

    return ConfigRetriever.create(vertx, new ConfigRetrieverOptions().addStore(store));
  }
}

4. Configuration file read and use

@Slf4j
public class MainApp extends AbstractVerticle {

  @Override
  public void start(Promise<Void> startPromise) throws Exception {
    HttpServer server = vertx.createHttpServer();
    server.requestHandler(new MainRoute().create(vertx));

    ConfigProperties properties = config().mapTo(ConfigProperties.class);
    int port = properties.getServer().getPort();
    log.info("===>json: {}, port: {}", properties, port);
    server.listen(port, http -> {
      if (http.succeeded()) {
        startPromise.complete();
        log.info("HTTP server started on port {}", port);
      } else {
        startPromise.fail(http.cause());
      }
    });
  }
}

// Get current context Next config file 
JsonObject jsonObject = Vertx.currentContext().config();
ConfigProperties properties = jsonObject.mapTo(ConfigProperties.class);
