Get Instance of circuit breaker from configuration file


This is my configuration file.

resilience4j.circuitbreaker:
  instances:
    backendB:
      registerHealthIndicator: true
      slidingWindowSize: 10
      minimumNumberOfCalls: 10
      permittedNumberOfCallsInHalfOpenState: 3
      waitDurationInOpenState: 5s
      failureRateThreshold: 50
      eventConsumerBufferSize: 10

I am trying to create bean of my feign client using Resilience4jFeign but the circuit breaker object is initialized with default configuration as the name suggest CircuitBreaker.ofDefaults. I can't find any ways to get my instance of circuit breaker from configuration to an object.

    @Bean
    public CommunicationServiceProxy communicationServiceProxy(){
        CircuitBreaker circuitBreaker = CircuitBreaker.ofDefaults("backendB");
        FeignDecorators decorators = FeignDecorators.builder()
                .withCircuitBreaker(circuitBreaker)
                .withFallbackFactory(CommunicationFallBack::new)
                .build();
        return Resilience4jFeign
                .builder(decorators)
                .encoder(new JacksonEncoder())
                .decoder(new JacksonDecoder())

                .target(CommunicationServiceProxy.class, "http://localhost:8081");
    }

Solution

  • I found the solution and it was using the CircuitBreakerRegistry. Instead of creating registry using

    CircuitBreakerRegistry.ofDefaults()
    

    one need to autowired them.

            @Autowired
            private CircuitBreakerRegistry circuitBreakerRegistry;
