盘点总结

一、盘点列表逻辑梳理

1、RFID耗材逻辑处理

private List<FhvcInventoryConsumablesVo> judgeRfidConsumables(FhvcInventoryDto dto) {
        // 耗材柜组在柜耗材的列表，根据cstId和deviceId区分
        List<FhvcInventoryConsumablesVo> inventoryConsumablesVos = fhvcInventoryService.inventoryCurrentConsumables(
                dto.getDeviceId(), FhvcInventory.STATUS_TWOIN, dto.getThingId(), Cst.SCAN_RFID);
        // 扫描到的epc
        List<String> epcs = dto.getScanEpcDetails().stream().map(s -> s.getEpc()).collect(Collectors.toList());
        dto.setEpcs(epcs);
        List<String> noralEpcs = new ArrayList<String>();
        List<String> addEpcs = new ArrayList<>();
        List<String> reduceEpcs = new ArrayList<>();
        List<String> errorEpcs = new ArrayList<>();
        List<String> rightEpcs = new ArrayList<>();

        differentEpcs(dto, epcs, addEpcs, reduceEpcs, errorEpcs, rightEpcs);
        if (rightEpcs != null && !rightEpcs.isEmpty()) {
            List<FhvcInventory> fhvcInventories = corresDevice(rightEpcs, dto);
            inventoryConsumablesVos = judgeNormalEpc(inventoryConsumablesVos, fhvcInventories, noralEpcs);

        }

        setMoreAndLittileEpcs(dto, addEpcs, rightEpcs, noralEpcs, reduceEpcs);

        return inventoryConsumablesVos;

    }

1）先根据deviceId和thingId查询出在柜的耗材基础信息：

List<FhvcInventoryConsumablesVo> inventoryConsumablesVos = fhvcInventoryService.inventoryCurrentConsumables(
            dto.getDeviceId(),FhvcInventory.STATUS_TWOIN, dto.getThingId(), Cst.SCAN_RFID);

2）根据传进来RFID扫描到的EPC求出正确的（库存里有的）和错误的（库存里不存在）EPC

List<String> allEpcs=fhvcInventoryService.allEpcs();
         //扫描到的epc和全部epc求差集就是错误的epc
        errorEpcs.addAll((List<String>) CollectionUtils.subtract(epcs, allEpcs));         
        //扫描到epc与库里有的epc求交集就是正常的epc
        rightEpcs.addAll((List<String>) CollectionUtils.intersection(epcs, allEpcs));    
dto.setErrorEpcs(errorEpcs);    

 3）根据正确的EPC查询出库存信息。并求出盘盈的EPC和正常在柜子的EPC

//查询出柜子本应所在柜子和司机所在柜子，用isSameDevice,如果一致为true否则为false

private List<FhvcInventory> corresDevice(List<String> rightEpcs, FhvcInventoryDto dto) {
        List<FhvcInventory> fhvcInventories=fhvcInventoryService.findFhvcInventoryByEpcs(rightEpcs);
        // 把扫描的epc的deviceId和详情对应上
        for (FhvcInventory fhvcInventory : fhvcInventories) {
            for (ScanEpcDetail scanEpcDetail : dto.getScanEpcDetails()) {
                if (scanEpcDetail.getEpc().equals(fhvcInventory.getEpc())) {
                    if (scanEpcDetail.getDeviceId().equals(fhvcInventory.getDeviceId())) {
                        fhvcInventory.setIsSameDevice(true);
                    }else {
                        fhvcInventory.setIsSameDevice(false);
                    }
                    fhvcInventory.setDeviceId(scanEpcDetail.getDeviceId());
                }
            }
        }
        return fhvcInventories;
    }

private List<FhvcInventoryConsumablesVo> judgeNormalEpc(List<FhvcInventoryConsumablesVo> inventoryConsumablesVos,
            List<FhvcInventory> fhvcInventories, List<String> noralEpcs) {
        // 对比出正常的epc
        for (FhvcInventoryConsumablesVo inventoryConsumablesVo : inventoryConsumablesVos) {
            List<String> addEpcs1=new ArrayList<String>();
            Integer num=0;
            for (FhvcInventory fhvcInventory : fhvcInventories) {

                    num=num+1;

            List<String> noralEpcs, List<String> reduceEpcs) {
        // 找出盘盈的epc
        addEpcs = (List<String>) CollectionUtils.subtract(rightEpcs, noralEpcs);

                dto.getThingId(), Cst.SCAN_RFID);

        // 扫描到的正常耗材与全部在库耗材做差集即为未扫描到的即为盘亏
        reduceEpcs = (List<String>) CollectionUtils.subtract(inEpcs, noralEpcs);

        // 即盘盈又盘亏的epc，不进行显示
        List<String> commonEpcs = (List<String>) CollectionUtils.intersection(addEpcs, reduceEpcs);
        addEpcs.removeAll(commonEpcs);
        reduceEpcs.removeAll(commonEpcs);

        dto.setAddEpcs(addEpcs);
