Spring Boot API Validation & Error Handling


Your Spring Boot API can look perfect… yet silently accept *invalid emails, negative prices, null values, and broken data* — until production fails.
In this video, you’ll learn **Spring Boot Validation the RIGHT way**, not just basic annotations, but **real-world REST API validation**, **custom validators**, **validation groups**, **nested object validation**, **service-layer validation**, and **global exception handling**.

We’ll cover *how Spring Boot validation works internally**, why missing `@Valid` destroys APIs, and how professionals design **clean, safe, production-ready backend systems* using Bean Validation (JSR-303 / Hibernate Validator).

By the end of this video, you’ll know:
✔ How to validate REST APIs correctly
✔ How to create custom validation annotations
✔ How to handle validation errors globally
✔ Common mistakes that break production systems
✔ Best practices used in real Spring Boot projects

This tutorial is perfect for **Java developers, Spring Boot beginners, backend engineers, and interview preparation**.
