Can I customize the error code system?

Yes, the skill provides a template ErrorCode enum that you can extend with your own project-specific codes, messages, and HTTP status mappings.

What framework is this error handling skill designed for?

This skill is specifically designed for Java-based backend applications using the Spring Boot framework, utilizing @RestControllerAdvice and SLF4J logging.

How does this improve system observability?

By standardizing logging levels (WARN for business exceptions, ERROR for system failures) and providing structured error responses, it makes it easier to track and debug production issues.

Does it support field-level validation errors?

Yes, it includes specialized handling for MethodArgumentNotValidException to provide detailed feedback on which specific fields failed validation.

API 개발

Standardizes Java and Spring Boot backend error handling, exception hierarchies, and logging for consistent API responses.

This skill provides a comprehensive framework for implementing robust error handling in Spring Boot applications based on the Allra development standards. It defines a structured business exception hierarchy, centralized global exception handling using @RestControllerAdvice, and a standardized ErrorResponse DTO. By enforcing consistent ErrorCode enums and logging strategies, it ensures that backend services produce predictable, frontend-friendly error messages while maintaining high-quality system logs for debugging and monitoring.
