A Boring Error Format Is a Feature: Building a Consistent Error Envelope in Spring Boot

1. 1Define a custom error envelope class using Spring Boot's ErrorResponse class
2. 2Implement a global error handler using @RestControllerAdvice to catch and handle exceptions
3. 3Configure the error handler to return the custom error envelope
4. 4Test the error handling mechanism using Postman or other API testing tools
5. 5Refine the error envelope to include relevant details such as error codes and messages

Backend developers and API designers can benefit from this to ensure consistent error handling across their APIs, making it easier for clients to handle errors and for teams to debug issues

💡 A consistent error envelope helps reduce debugging time and improves client-side error handling
