How do you get default methods in Spring Data repositories to hit the cache?

This is related to this question, which shows that default methods in Spring Data repositories do not hit the cache: Will default methods in Spring Data repositories hit caches on other methods?

I have this cached method:

    @Cacheable("codeType-findIdByCode")
    default Long findIdByCodeRequired(final String code) {
        if (StringUtils.isBlank(code)) {
            throw new DataCheckException(MSG_CODE_REQUIRED, getEntityMessageArgument());
        }

        return findIdByCode(code).orElseThrow(notFound(code));
    }

And I want this default method to hit the cache:

    default T getReferenceByCodeRequired(final String code) {
        return getOne(findIdByCodeRequired(code));
    }

Note that I tried this mechanism and it did not work:

    default T getReferenceByCodeRequired(final String code) {
        @SuppressWarnings("unchecked")
        final CodeTypeRepository<T> codeTypeRepo = (CodeTypeRepository<T>) AopContext.currentProxy();
        return getOne(codeTypeRepo.findIdByCodeRequired(code));
    }

How can I get it to hit the cache without moving the default method out of the repository.

Reasons for keeping it in the repository: its a parent repository of a fair number of child repositories. A service method version of getReferenceByCodeRequired would need to take in the child repository itself in order to compose the two repository calls (findIdByCodeRequired and getOne)

Also, I don't want to put @Cacheable on the getReferenceByCodeRequired method as I'm trying to avoid caching entities.
