This repository features a concise tutorial on building a basic Telegram bot. Learn how to seamlessly integrate it with Spring Boot 2.5.2 and leverage the functionality of the OpenAI-Java library. Follow along step-by-step to create your own interactive bot capable of interacting intelligently with users.

At the end of this tutorial, you'll have a fully functional Telegram bot similar to the one described in the upcoming video.

As you see , the answer received by the bot is not complete. I think it's due to the OpenAI-Java library. I will make another same repo with another implementation.

As you can observe, the response received by the bot appears to be incomplete. I suspect this issue may be related to the OpenAI-Java library. Therefore, I plan to create a new repository with a different implementation.

In Idea create a new Maven project

We will have a pom.xml file which we will change.

Editing the pom.xml file

Create main class , the entry point of our application

You have to find the BotFather in Telegram. Pay attention to the official BotFather

Edit pom.xml file Add Telegram and lombok dependencies

Two ways to create bots (Polling and Webhooks) I will touch the Polling. Create new package controller and a new class TelegramBotthat will extend a class from Telegram TelegramLongPollingBot and override three methods

After the app started

1 - First, let's refactor and export token and username to application.properties file. Let's create it in resources folder .

2 - Remove hardcoded data from TelegramBot class

3 - Write implementation

private methods

running the app

Now let's write code using OpenAi

We have to generate an OpenAI API key. If you don't have one, you can sign up for it on the OpenAI website.

I have found a library on git but it seems that his library does not work fine. Add new dependency in pom.xml file.

Let's remove hardcoded tokens from .properties file and set it to env variables. I will not show you how to do it you can google it yourself.

Now we will add configuration to Openai API

Now let's inject OpenAiService bean in our TelegramBot

Let's implement getResponseFromChatGPT()

Before finish, let's make our bot more beautiful and functional. Inside method onUpdateReceived() , we will write three commands that our bot will accept.

Static text Method chatGptCommandReceived() Method getResponseFromChatGpt() Method sendTextMessage() Method processPromptResponse()

Now we will add menu like this.

For this we will export configs for Telegram Bot to a separate class and inject it into TelegramBot class. Create a new BotConfig.java class. Make some changes in TelegramBot.java class.

Let's run the App.
