Master Exception Handling in Spring Boot 3.0: Global vs. Custom Patterns
🛠️ Master Exception Handling in Spring Boot 3.0: Global vs. Custom Patterns
Are you still using messy try-catch blocks in your Microservices? It’s time to upgrade! In this video on Tech World with Preet, we are diving deep into the most efficient ways to handle errors in Spring Boot 3.0 using a real-world Flight Microservices project.
Handling exceptions correctly is the difference between a fragile app and a resilient, production-ready system. We’ll compare Global Exception Handling with @ControllerAdvice against Custom Exceptions, and show you how to choose the right strategy for your architecture.
🔍 What You’ll Learn:
The Spring Boot 3.0 Standard: Using ProblemDetail (RFC 7807) for consistent error responses.
Global vs. Custom: When to use @RestControllerAdvice vs. throwing domain-specific exceptions.
Flight Microservice Implementation: Real-world examples like FlightNotFoundException and SeatNotAvailableException.
Centralized Logic: Reducing code duplication and keeping your business logic clean.
Validation Errors: How to handle @Valid and binding exceptions gracefully.
✈️ Why Flight Microservices?
Microservices require consistent error contracts. Whether you're building booking engines or cargo management portals, your API needs to return clear, actionable error messages to the frontend.
