两个list有一个数据相同，合并两个list

List<OrderInfo> list = orderInfoService.selectPnum();
PageList<OrderInfo> orderList = orderInfoService.listPage(orderInfo, pageBounds);

for (OrderInfo OrderList : orderList) {

for (OrderInfo List : list) {
         if(OrderList.getOrderCode().equals(List.getOrderCode())){
          OrderList.setOrderGoodsNum(List.getOrderGoodsNum());
          break;
         }
        }
       }
