在 spring 中提供了个 ResponseBodyAdvice 接口，可以帮助我们将返回的值进行统一封装，代码如下

@ControllerAdvice
@Slf4j
public class MyResponseBodyAdvice implements ResponseBodyAdvice<Object> {

    @Override
    public boolean supports(MethodParameter returnType, Class<? extends HttpMessageConverter<?>> converterType) {
        log.debug("MyResponseBodyAdvice==>supports:" + converterType);
        log.debug("MyResponseBodyAdvice==>supports:" + returnType.getClass());
        log.debug("MyResponseBodyAdvice==>supports:" + MappingJackson2HttpMessageConverter.class.isAssignableFrom(converterType));
        return MappingJackson2HttpMessageConverter.class.isAssignableFrom(converterType);
    }

    @Override
    public Object beforeBodyWrite(Object body, MethodParameter returnType,
                                  MediaType selectedContentType,
                                  Class<? extends HttpMessageConverter<?>> selectedConverterType,
                                  ServerHttpRequest request, ServerHttpResponse response) {
        if (body == null) {
            return Result.success();
        }
        if (body instanceof Result || body instanceof File || body instanceof ResponseEntity) {
            return body;
        } else {
            log.debug("MyResponseBodyAdvice==>beforeBodyWrite:" + returnType + "," + body);
            return Result.success(body);
        }
    }
}

但是现在有个问题就是，一些第三方组件也使用 json 通信，比如 swagger。这时候就需要排除这些东西，或者是指定切面才进行统一封装。

请问 V 友们应该怎么做，可以不用 ResponseBodyAdvice 接口
