}

Setup project

Create TelegramBot

Create one Telegram Bot by the link.

Initialize Spring Boot Application

[username] and [token] should be replaced with real values, which you get at previous step. Annotation @EnableTelegramBot can be used to enable telegram bot controllers support.

@SpringBootApplication
@EnableTelegramBot
@Configuration
public class Application {
    @Bean
    public TelegramBotType telegramBotType() {
        return TelegramBotType.LONG_POLLING;
    }

    @Bean
    public TelegramBotBuilder telegramBotBuilder() {
        return new TelegramBotBuilder()
            .username("[username]")
            .token("[token]");
    }

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

Write controller

@TelegramBot
public class SimpleController {
    @TelegramMessage
    public SendMessage defaultAction(long userId, User user, String message) {
        return new SendMessage()
            .setChatId(userId)
            .setText(String.format("Hello %s, you've send me %s", user.getFirstName(), message));
    }

    @TelegramCommand(commands = "/some_command", description = "Some command")
    public SendMessage someCommand(long userId, TelegramMessageCommand telegramMessageCommand) {
        return new SendMessage()
            .setChatId(userId)
            .setText(String.format("You've send me %s command with arguments: %s",
                telegramMessageCommand.getCommand(), telegramMessageCommand.getArgument()
            ));
    }
}

That's all.
