spring-boot-resilience4j

Fault tolerance and resilience patterns for Spring Boot microservices using Resilience4j. Provides Resilience4j patterns (circuit breaker, retry, rate limiter, bulkhead, time limiter, fallback) for Spring Boot 3.x fault tolerance with configuration and testing workflows. Add Resilience4j dependencies to your project. For Maven, add to pom.xml : For Gradle, add to build.gradle : Enable AOP annotation processing with @EnableAspectJAutoProxy (auto-configured by Spring Boot). Apply @CircuitBreaker annotation to methods calling external services: Configure in application.yml : See @references/configuration-reference.md for complete circuit breaker configuration options. Apply @Retry annotation for transient failure recovery: Configure retry in application.yml : See @references/configuration-reference.md for retry exception configuration. Apply @RateLimiter to control request rates: Configure in application.yml : Apply @Bulkhead to isolate resources. Use type = SEMAPHORE for synchronous methods: Use type = THREADPOOL for async/CompletableFuture methods: Configure in application.yml : Apply @TimeLimiter to async methods to enforce timeout boundaries: Configure in application.yml : Stack multiple patterns on a single method for comprehensive fault tolerance: Execution order: Retry → CircuitBreaker → RateLimiter → Bulkhead → Method All patterns should reference the same named...
