Using HTTP proxy

HTTP proxy support implemented since version 3.6.1

First of all you need to override constructor with DefaultBotOptions argument while inheriting from AbilityBot or TelegramLongPollingBot

public class MyBot extends AbilityBot {

    protected MyBot(String botToken, String botUsername, DefaultBotOptions botOptions) {
        super(botToken, botUsername, botOptions);
    }

    public int creatorId() {
        return 0;
    }

    public Ability pingPong() {
        return Ability
                .builder()
                .name("ping")
                .info("ping pong")
                .locality(ALL)
                .privacy(PUBLIC)
                .action(ctx -> silent.send("pong", ctx.chatId()))
                .build();
    }

}

Now you are able to set up your proxy

without authentication

public class Main {

    private static String BOT_NAME = "My test bot";
    private static String BOT_TOKEN = "..." /* your bot's token here */;

    private static String PROXY_HOST = "..." /* proxy host */;
    private static Integer PROXY_PORT = 3128 /* proxy port */;

    public static void main(String[] args) {
        try {

            ApiContextInitializer.init();

            // Create the TelegramBotsApi object to register your bots
            TelegramBotsApi botsApi = new TelegramBotsApi();

            // Set up Http proxy
            DefaultBotOptions botOptions = ApiContext.getInstance(DefaultBotOptions.class);

            HttpHost httpHost = new HttpHost(PROXY_HOST, PROXY_PORT);

            RequestConfig requestConfig = RequestConfig.custom().setProxy(httpHost).setAuthenticationEnabled(false).build();
            botOptions.setRequestConfig(requestConfig);
            botOptions.setHttpProxy(httpHost);

            // Register your newly created AbilityBot
            MyBot bot = new MyBot(BOT_TOKEN, BOT_NAME, botOptions);

            botsApi.registerBot(bot);

        } catch (TelegramApiException e) {
            e.printStackTrace();
        }
    }
}

With authentication

public class Main {

    private static String BOT_NAME = "My test bot";
    private static String BOT_TOKEN = "..." /* your bot's token here */;

    private static String PROXY_HOST = "..." /* proxy host */;
    private static Integer PROXY_PORT = 3128 /* proxy port */;
    private static String PROXY_USER = "..." /* proxy user */;
    private static String PROXY_PASSWORD = "..." /* proxy password */;

    public static void main(String[] args) {
        try {

            ApiContextInitializer.init();

            // Create the TelegramBotsApi object to register your bots
            TelegramBotsApi botsApi = new TelegramBotsApi();

            // Set up Http proxy
            DefaultBotOptions botOptions = ApiContext.getInstance(DefaultBotOptions.class);

            CredentialsProvider credsProvider = new BasicCredentialsProvider();
            credsProvider.setCredentials(
                    new AuthScope(PROXY_HOST, PROXY_PORT),
                    new UsernamePasswordCredentials(PROXY_USER, PROXY_PASSWORD));

            HttpHost httpHost = new HttpHost(PROXY_HOST, PROXY_PORT);

            RequestConfig requestConfig = RequestConfig.custom().setProxy(httpHost).setAuthenticationEnabled(true).build();
            botOptions.setRequestConfig(requestConfig);
            botOptions.setCredentialsProvider(credsProvider);
            botOptions.setHttpProxy(httpHost);

            // Register your newly created AbilityBot
            MyBot bot = new MyBot(BOT_TOKEN, BOT_NAME, botOptions);

            botsApi.registerBot(bot);

        } catch (TelegramApiException e) {
            e.printStackTrace();
        }
    }
}
