寻找更好的解决方案来处理 micronaut 中的全局异常https://docs.micronaut.io/latest/guide/index.html#errorHandling

控制器

@Controller("/category")
public class CategoryController {
@Delete(uri = "/{id}")
public Maybe<HttpResponse> delete(@NotBlank String id) {
            LOG.info(String.format("API --> Deleting the specified category"));
            return iCategoryManager.Count(id).flatMap(item -> {
                if (item > 0) {
                    iCategoryManager.Delete(id).subscribe();
                    return Maybe.just(HttpResponse.noContent());
                } else
                    return Maybe.just(HttpResponse.notFound());
            });
    }
}

iCategoryManager.Count(id)导致如下异常，如何捕获GlobalExceptionHandler上的异常
