Spring Boot REST API Error Handling | Custom Exception Responses

🚀 Welcome to another episode of our Spring Boot Tutorial Series! 🚀

In this video, we cover Exception Handling in Spring Boot REST APIs and how to customize API responses for better error handling. When building REST APIs, handling errors correctly is essential for creating a smooth and professional experience for users. Learn how to catch exceptions, create custom error responses, and apply global exception handling in your Spring Boot applications.

📌 Topics Covered in This Video:
✅ What is Exception Handling? – Why proper error handling is crucial for APIs.
✅ Types of Exceptions in Spring Boot – Checked vs. Unchecked exceptions.
✅ Using @ExceptionHandler for Custom Error Handling – Handling specific exceptions.
✅ Global Exception Handling with @ControllerAdvice – Centralized exception management.
✅ Customizing API Error Responses – Creating user-friendly error messages.
✅ Logging Exceptions in Spring Boot – Best practices for debugging.
✅ Testing Exception Handling in APIs – Using Postman to verify responses.

🌟 Why Is Exception Handling Important in REST APIs?
Without proper exception handling, APIs can expose stack traces, confuse users, and create security vulnerabilities. A well-structured error response improves usability and debugging.

🛠️ Step-by-Step Guide to Exception Handling in Spring Boot:
1️⃣ Use @ExceptionHandler in Controllers – Catch and handle specific exceptions.
2️⃣ Implement @ControllerAdvice for Global Exception Handling – Centralize error handling logic.
3️⃣ Customize Error Response Structures – Return meaningful error messages in JSON format.
4️⃣ Use ResponseEntity for Better Error Responses – Set HTTP status codes properly.
5️⃣ Log Errors for Debugging – Use SLF4J or Logback for error tracking.
6️⃣ Test API Error Responses – Simulate failures and verify API behavior with Postman.
