How to configure resilience4j.circuitbreaker in @Bean without properties.yml

Thanks for raising a Resilience4j issue. Please provide a brief description of your problem along with the versions you are using. If possible, please also consider putting together a complete JUnit test that reproduces the issue.

Java version: 8

Problem description:

Hi, I’m trying to configure resilience without the need to put the settings in the properties.yml. I created my configuration bean but the circuit is not working

@Slf4j
@Configuration
@Component
@RefreshScope
public class CircuitBreakerAutoConfiguration {
  
  @Bean
  public CircuitBreakerRegistry defaultGenesisCircuitBreaker(
      @Value("${application.circuit-breaker.genesis.default."
          + "ringBufferSizeInClosedState:30}")
          int ringBufferSizeInClosedState,
      @Value("${application.circuit-breaker.genesis.default."
          + "ringBufferSizeInHalfOpenState:10}")
          int ringBufferSizeInHalfOpenState,
      @Value("${application.circuit-breaker.genesis.default."
          + "failureRateThreshold:50}")
          long failureRateThreshold,
      @Value("${application.circuit-breaker.genesis.default."
          + "waitDurationInOpenState:10000}")
          long waitDurationInOpenState) {
    log.info("Configuring custom Genesis Circuit Breaker genesis.default");
    return CircuitBreakerRegistry.of(circuitBreakerConfig());
  }

  @Bean
  public CircuitBreakerConfig circuitBreakerConfig() {
    log.info("circuitBreakerConfig");
    return CircuitBreakerConfig.custom()
            .minimumNumberOfCalls(2)
            .failureRateThreshold(50)
            .waitDurationInOpenState(Duration.ofMillis(1000))
            .permittedNumberOfCallsInHalfOpenState(2)
            .slidingWindowSize(2)
            .build();
  }

  @Bean
  public CircuitBreaker defaultCircuitBreaker() {
    CircuitBreakerConfig config = CircuitBreakerConfig.custom()
            .minimumNumberOfCalls(2)
            .build();
    return CircuitBreaker.of("default", config);
  }
}

I need to abstract this configuration to put it within a framework of my own. The only way it works is when I put the settings in the properties

resilience4j.circuitbreaker:
  configs:
    default:
      registerHealthIndicator: false
      slidingWindowSize: 10
      minimumNumberOfCalls: 5

Like @RobWin indicated, I Autowired the CircuitBreakerRegistry instead of creating my own through CircuitBreakerRegistry.of(config). This allowed me to use registry.circuitBreaker(name, config) to add new circuit breakers with my custom configurations in my code without any yaml entries.

why not using customizers for circuit breaker configuration overriding ? which is supported already through resilience4j spring boot starter :

@Bean
public CircuitBreakerConfigCustomizer testCustomizer() {
    return CircuitBreakerConfigCustomizer
        .of("test", builder -> builder.slidingWindowSize(100));
}
