弹性4J型断路器Spring靴的Bean结构

Question

我想将我的断路器配置从application.yml文件移到某个配置java文件作为bean声明信标，这使得application.yml文件变得很大，我是否可以从applciation.yml中删除配置并使用配置注释来定义断路器配置。我有配置java文件，代码如下：

@Configuration
@Component
public class CircuitBreakConfig {

  @Bean
  public CircuitBreaker defaultCircuitBreaker() {
    CircuitBreakerConfig circuitBreakerConfig = CircuitBreakerConfig.custom()
      .failureRateThreshold(50)
      .slidingWindowSize(5)
      .waitDurationInOpenState(Duration.ofMillis(6000))
      .recordExceptions(IOException.class, TimeoutException.class,DataIntegrityViolationException.class)
      .build();
  // Create a CircuitBreakerRegistry with a custom global configuration
  CircuitBreakerRegistry circuitBreakerRegistry = 
     CircuitBreakerRegistry.of(circuitBreakerConfig);

  // Get or create a CircuitBreaker from the CircuitBreakerRegistry 
  // with the global default configuration
   return circuitBreakerRegistry.circuitBreaker("default"); 
  }

}

在我的服务文件中，我正在注释断路器的方法，如

@CircuitBreaker(name = "default", fallbackMethod = "fallback")
    public Employee createEmployeeDefinition(Employee emp)  throws Exception{
        if(Objects.nonNull(sample)){
            return EmployeeRepository.save(sample);
        }
        return null;
    }

    public Employee fallback(Employee emp,Exception ex) throws Exception{
        System.out.println(ex.getClass()+"  "+ex.getMessage() );
        return null;
    }

在目前的实现中，我的断路器无法达到开路状态。请给我一些建议
