System Documentation

What problem does it solve?

Java Spring Boot applications often struggle with inconsistent error responses and scattered exception handling, leading to confusing client errors and difficult debugging. This Skill provides a centralized pattern to implement global error handling, a set of domain exceptions, and a uniform ApiResponse envelope to improve API reliability and observability.

Core Features & Use Cases

  • Global error handling via @RestControllerAdvice
  • Custom domain exceptions mapped to appropriate HTTP status codes
  • ApiResponse envelope for error details
  • Structured logging with SLF4J MDC for correlation IDs
  • Optional resilience support with Resilience4j for external calls and retries

Quick Start

Configure a global RestControllerAdvice, define domain exceptions, and map them to ApiResponse errors.
