Spring Boot 4 : REST API - Fetch User By ID | How to Implement | GET Mapping | DinaTechy #springboot

In this video, we’ll create a Get User By ID REST API using Spring Boot 4 and Java 8 style coding.

Instead of jumping straight into code, I’ll walk you through how a real backend developer thinks while designing a GET API:

- How to use @GetMapping and @PathVariable correctly
- How to fetch a single user by ID
- How to return proper HTTP status codes
- How to handle the “user not found” scenario cleanly

This example follows a simple controller → service structure, making it easy to understand for beginners and also useful for interview preparation.

If you’re learning Spring Boot, building CRUD APIs, or revising core REST concepts, this video will help you write clean, readable, and practical code.
