Master Global Exception Handling and Data Validation in Spring Boot 3! In this tutorial, we move beyond basic try-catch blocks to build a production-ready error-handling layer using @RestControllerAdvice. We also dive deep into Request Body Validation. You'll learn how to use standard Jakarta validation annotations like @Valid, @NotNull, and @Size, and we take it a step further by creating a Custom Validation Annotation from scratch to handle unique business logic. What you will learn in this video: ✅ How to use @RestControllerAdvice and @ExceptionHandler for global error management. ✅ Creating a custom Error Response structure for clean API outputs. ✅ Implementing DTO validation with the @Valid annotation. ✅ Step-by-step guide to creating a Custom Annotation and ConstraintValidator. ✅ Handling MethodArgumentNotValidException to return user-friendly error messages.
