Spring Boot Tutorial #4 — Global Exception Handler in Spring Boot

In this video you will learn how to implement a Global Exception Handler in Spring Boot using @RestControllerAdvice and @ExceptionHandler.
This technique makes your API error handling clean, consistent and scalable — and avoids repetitive try/catch blocks inside your Controllers.

You will also discover the bonus explanation about @Autowired — how Spring performs Dependency Injection internally, and why this is different compared to standard Java instantiation.

Topics we cover:

Centralized error handling in Spring Boot

Using @RestControllerAdvice and @ExceptionHandler

Returning structured JSON error response

Best practice for handling validation errors

How Spring Autowired works behind the scenes

Why DI container = better maintainability

Clean architecture for enterprise API
