I think the method findOne() is unsupported by version 1.5.1.SNAPSHOT of SPRING BOOT , so in 2.0.1.SNAPSHOT it's replaced by FindById() which is a QueryByExampleExecutor it's an Optional method (see Optional in JAVA 8) so I resolved the problem like this:

@Override public Compte consulterCompte(String code) throws NotFoundException {
    Optional<Compte> cp = compteRepository.findById(code);
    return cp.orElseThrow(
        () ->  new NotFoundException("Unable to get Account with Code = " + code)
    );  
}
