zipkin can not report the span to kafka when project utilize swagge-3.0.0

[Layfolk-zcy]

springBoot>2.6.3
<spring-cloud-dependencies.version>2021.0.1
<spring-cloud-alibaba-dependencies.version>2021.0.1.0

springfox-boot-starter>3.0.0
phenomenon:

when i put the springfox dependency into project, which the kafka server cant recept the span message. After i try remove springfox dependency the kafka server ,which working i wished.

when swagger integrate springBoot 2.6.3 , i refer some blogs added some Bean because springboot 2.6.3 uncompatible sprignfox 3.0.0 triggered some exceptions . Such as:

`

@component
public class SwaggerBeanPostProcessor implements BeanPostProcessor {

  @Override
  public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException {
      if (bean instanceof WebMvcRequestHandlerProvider || bean instanceof WebFluxRequestHandlerProvider)
      {
          List<RequestMappingInfoHandlerMapping> handlerMappings = getHandlerMappings(bean);
          customizeSpringfoxHandlerMappings(handlerMappings);
      }
      return bean;
  }

  private <T extends RequestMappingInfoHandlerMapping> void customizeSpringfoxHandlerMappings(List<T> mappings) {
      List<T> copy = mappings.stream()
              .filter(mapping -> mapping.getPatternParser() == null)
              .collect(Collectors.toList());
      mappings.clear();
      mappings.addAll(copy);
  }

  @SuppressWarnings("unchecked")
  private List<RequestMappingInfoHandlerMapping> getHandlerMappings(Object bean) {
      try {
          Field field = ReflectionUtils.findField(bean.getClass(), "handlerMappings");
          field.setAccessible(true);
          return (List<RequestMappingInfoHandlerMapping>) field.get(bean);
      }
      catch (IllegalArgumentException | IllegalAccessException e) {
          throw new IllegalStateException(e);
      }
  }

}
