ChatGPT & Spring AI: Your First AI App

Описание: 🤖 Build your first AI app with Spring AI & ChatGPT! Learn to connect Spring Boot 3 to OpenAI, step-by-step. 💻 In this tutorial, we start from scratch to create a practical "Trip Planner" application powered by the intelligence of ChatGPT.

This video is your perfect introduction to integrating large language models (LLMs) into the Spring ecosystem. We'll cover everything from project setup to making your first AI-powered API call.

🛠️ In this step-by-step guide, you will learn how to:

🚀 Create a new Spring Boot 3 project from start.spring.io with the necessary Spring AI and OpenAI dependencies.
🔑 Navigate the OpenAI platform to generate a new API key for ChatGPT.
🔒 Securely manage your OpenAI API key using environment variables in IntelliJ IDEA to avoid exposing it in your code.
⚙️ Configure application.properties with your API key and a specific ChatGPT model (e.g., GPT-4).
🧠 Create an AIService class that uses Spring AI's ChatClient to communicate with the ChatGPT API.
✈️ Build a "Trip Planner" REST Controller that accepts user input (like destination, budget, dates).
📝 Craft a detailed and effective prompt to send to ChatGPT to get the best possible tour plan.
🧪 Test your AI-powered endpoint using Postman and see the generated trip plan from ChatGPT in real-time.
🐛 Debug common issues, like incorrect property names in your request body.
