Watch Spring Rest Client Error Handler Video Tutorials & Courses

Are you handling errors in the Spring RestClient the right way? In this video, I'll walk you through best practices for error handling, from using the default RestClient builder to global exception handlers, custom exceptions, and the brand-new retry support built into Spring Framework 7. We'll build a REST client from scratch that talks to HTTPBin.org, set up a default status handler to catch HTTP errors centrally, create custom exceptions with Problem Detail responses (RFC 9457), extract REST client configuration into a reusable bean, and finish by adding automatic retries with exponential backoff using the new @Retryable annotation in Spring Boot 4. - Always use the default RestClient.Builder — it comes pre-configured with observability and other Spring Boot features - Use defaultStatusHandler on the builder to centralize error handling instead of duplicating status checks in every method - Create custom exceptions (e.g., NotFoundException, ApiException) and a global @RestControllerAdvice to return structured ProblemDetail responses - Extract your RestClient configuration into a @Configuration class with a @Bean so it can be injected and reused across controllers - Leverage the new @Retryable annotation in Spring Framework 7 for built-in retry with exponential backoff on transient failures If you found these tips helpful, smash that thumbs up button, subscribe for more Spring Boot content, and drop a comment with YOUR favorite RestClient error handling strategies! 0:00 - Intro & Project Setup 1:30 - Exploring HTTPBin.org as a Test API 2:45 - Tip #1: Use the Default RestClient Builder 4:30 - Making GET Requests & Default Error Behavior 5:45 - Suppressing Default Exceptions with onStatus 6:30 - Why Per-Method Status Checking Doesn't Scale 7:15 - Using defaultStatusHandler on the Builder 8:00 - Tip #2: Global Exception Handler with @RestControllerAdvice 9:15 - Returning ProblemDetail (RFC 9457) Responses 10:30 - Extracting RestClient Config into a @Bean 12:00 - Custom Exceptions: NotFoundException & ApiException 13:30 - Tip #3: @Retryable with Exponential Backoff (Spring Framework 7) 15:30 - Demo: Retrying Unstable Endpoints 16:30 - Recap & Final Thoughts 🔗Resources & Links mentioned in this video: GitHub Repository: https://github.com/danvega/rest-client-error-handling HTTPBin.org - HTTP Request & Response Service: https://httpbin.org Spring Framework 7 Documentation - RestClient: https://docs.spring.io/spring-framework/reference/integration/rest-clients.html RFC 9457 - Problem Details for HTTP APIs: https://www.rfc-editor.org/rfc/rfc9457 👋🏻Connect with me: Website: https://www.danvega.dev Twitter: https://twitter.com/therealdanvega Github: https://github.com/danvega LinkedIn: https://www.linkedin.com/in/danvega Newsletter: https://www.danvega.dev/newsletter SUBSCRIBE TO MY CHANNEL: http://bit.ly/2re4GH0 ❤️ Key Highlights & Overview: Understanding <strong>Spring Rest Client Error Handler</strong> requires clear step-by-step guidance and practical hands-on visual demonstrations.
