How I Decoupled Circuit Breaker from the Code with AOP in Spring Boot for Better Code Maintenance

CircuitBreakerAOPConfig.java

//code is omitted for brevity

@Aspect
@Component
public class CircuitBreakerAOPConfig {

  private static final Logger LOGGER = LoggerFactory.getLogger(CircuitBreakerAOPConfig.class);

  private final CircuitBreaker circuitBreaker;

  public CircuitBreakerAOPConfig(CircuitBreakerRegistry circuitBreakerRegistry){
    this.circuitBreaker = circuitBreakerRegistry.circuitBreaker("myAPOConfiguredMyCircuitBreaker");
  }

  @Around("@annotation(com.skaveesh.dcb.annotation.EnableCircuitBreakerScan)")
  public Object around(ProceedingJoinPoint proceedingJoinPoint) {

    Object returnValue = execute(rethrowSupplier(proceedingJoinPoint::proceed), this::fallback);

    LOGGER.info("Around after class - {}, method - {}, returns - {}", proceedingJoinPoint.getSignature().getDeclaringType().getName(), proceedingJoinPoint.getSignature().getName(), returnValue);

    return returnValue;
  }

  private <T> T execute(Supplier<T> supplier, Function<Throwable, T> fallback) {
    return Decorators.ofSupplier(supplier)
        .withCircuitBreaker(circuitBreaker)
        .withFallback(fallback)
        .get();
  }

  private ResponseEntity<String> fallback(Throwable ex) {
      throw new CircuitBreakerDownstreamCallException(ex.getMessage());
  }

}
