TgWebhook

Description

This library contains an implementation to process Webhook requests for rubenlagus/TelegramBots.

It provides simple ways to process incoming requests. Code reduction is achieved through the use of annotations to configure accepted requests.

@AcceptTypes({UpdateType.MESSAGE})
@Component
public class StartHandler {

  @CommandMethod(value = "/start", locality = Locality.PRIVATE)
  public BotApiMethod onStartCommand(AbsSender bot, Message message, List<String> args) {
    return new SendMessage()
      .setText("Hello world")
      .setChatId(message.getChatId());
  }

}

    handlers.values().forEach(handler -> {
      Handlers.addHandler(handler);
    });
  }

}
  /*
