Spring Boot REST API CRUD Tutorial | GET, POST, PUT & DELETE Using HashMap | Part 1

🚀 Spring Boot REST API CRUD Tutorial — Part 1 In this video, I explain how to create a simple REST API using Spring Boot and implement CRUD operations using a HashMap for storing data. This is Part 1, where we focus on understanding and writing the complete code. In Part 2, I will demonstrate how these APIs work practically using Postman. 📌 What You'll Learn ✅ How to create a REST API using Spring Boot ✅ Understanding the Controller layer ✅ Understanding the Service layer ✅ Using HashMap to store data ✅ GET API – Fetch data ✅ POST API – Create data ✅ PUT API – Update data ✅ DELETE API – Delete data ✅ Understanding the flow of a REST API 🛠️ Technologies Used • Java • Spring Boot • REST API • HashMap • Postman (covered in Part 2) 🎥 Part 2 — API Testing with Postman In the next video, I will practically test the APIs created in this video using *Postman* and demonstrate the GET, POST, PUT and DELETE operations. 🔗 Part 2:    • Spring Boot REST API with Postman | GET, P...   💡 What's Next? In these videos, I am using HashMap for data storage to understand the REST API concepts clearly. In a future video, I will take the same REST API and integrate it with an actual database to store and manage the data.
