我正在使用MessageListener实现从RabbitMQ接收消息，但securityContextHolder.getContext()只在onMessage中返回null，但它对应用程序的其余部分工作正常：

@Override
public void onMessage(Message message) {
    Gson gson = new Gson();
    ControleResult resultControle = gson.fromJson(new String(message.getBody()), Facture.class);
    Optional<Facture> optional = dossierDao.findById(resultControle.getId());
    Facture facture= null;
    if (optional.isPresent()) {
        facture= optional.get();
    }
  
    factureDao.save(facture);
    log.info("USER     " + getLoggedInUserName());   
}

private String getLoggedInUserName() {
    Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
    if (authentication != null && authentication.isAuthenticated()) {
        Object principal = authentication.getPrincipal();
        if (principal instanceof UserDetails) {
            ConnectedUser userDetails = (ConnectedUser) authentication.getPrincipal();

            return String.format("%s %s",userDetails.getUsername(), userDetails.getUserlastname());
        }
    }
    return null; 
}
