又被逼着优化代码，这次我干掉了出入参 Log 日志

public OrderDTO getOrder(OrderVO orderVO, String name) {
        log.info("订单详情入参：orderVO={},name={}", JSON.toJSONString(orderVO), name);
        OrderDTO orderInfo = orderService.getOrderInfo(orderVO);
        log.info("订单详情结果：orderInfo={}", JSON.toJSONString(orderInfo));
        return orderInfo;
}
