Hello,

what do you mean by dot form?

Another option could be to use MapStruct and do something like this:

public List<AdminDto> getAdminsByCompanyId(String companyId) {
    return adminRepo.findAllByCompanyId(companyId).stream()
            .map(AdminMapper::toDto) // I assume you could also do this .map(AdminDto::convertDaoToDto)
            .collect(Collectors.toList());
}

if you want to wrap into your object ReporterResponse the resutlat you could also do this:

public ResponseDate getAdminsByCompanyId(String companyId) {
        ReporterResponse reporterResponse = new ReporterResponse();
        reporterResponse.setData(adminRepo.findAllByCompanyId(companyId).stream()
                .map(AdminMapper::toDto)
                .collect(Collectors.toList()));
        reporterResponse.setStatus(true);
}

Hope it help
