   *
   * @param appleId
   * @return
   */
  @Locked(keys = "#appleId")
  @GetMapping("/get/apple")
  public String getApple(Long appleId) {
    if (apple <= 0) {
      return "对不起, 已经没货了!";
    } else {
      apple = apple - 1;
      log.info("购买成功, 现在apple数量为:{}", apple);
      return "购买成功!";
    }
  }

  /**
   * 不带分布式锁, 会出现超卖
