List<UserClientDto> usersList = accountService.listUsers();
LOGGER.debug("[AccountRestController] display: end");
return ResponseBuilder.buildSuccessResponse(new ListResponse<>(usersList), Provider.COMPANY);
}
@PostMapping(value = "")
public GenericResponse saveUser (@RequestBody UserClientDto userClientDto) {
LOGGER.debug("[AccountRestController] saveUser: Start");
accountService.addNewUser(userClientDto);
LOGGER.debug("[AccountRestController] saveUser: End");
