3.仓储管理

一、获取仓库列表

@Override
    public PageUtils queryPage(Map<String, Object> params) {

        QueryWrapper<WareInfoEntity> queryWrapper = new QueryWrapper<>();

        String key = (String) params.get("key");

        if (!StringUtils.isEmpty(key)) {
            queryWrapper.eq("id",key)
                    .or().like("name",key)
                    .or().like("address",key)
                    .or().like("areacode",key);
        }


        IPage<WareInfoEntity> page = this.page(
                new Query<WareInfoEntity>().getPage(params),
                queryWrapper
        );

        return new PageUtils(page);
    }

二、查询未领取的采购单

/**
     * 查询未领取的采购单
     * @param params
     * @return
     */
    @Override
    public PageUtils queryPageUnreceive(Map<String, Object> params) {

        QueryWrapper<PurchaseEntity> queryWrapper = new QueryWrapper<PurchaseEntity>()
                .eq("status",0).or().eq("status",1);

        IPage<PurchaseEntity> page = this.page(
                new Query<PurchaseEntity>().getPage(params),
                queryWrapper
        );

        return new PageUtils(page);
    }

三、合并采购需求

/**
 * 合并采购需求
 * @param mergeVo
 */
@Transactional(rollbackFor = Exception.class)
@Override
public void mergePurchase(MergeVo mergeVo) {

    Long purchaseId = mergeVo.getPurchaseId();

    //没有选择任何【采购单】，将自动创建新单进行合并。
    if (purchaseId == null) {
        PurchaseEntity purchaseEntity = new PurchaseEntity();
        //设置采购单的默认状态
        purchaseEntity.setStatus(WareConstant.PurchaseStatusEnum.CREATED.getCode());

        purchaseEntity.setCreateTime(new Date());
        purchaseEntity.setUpdateTime(new Date());
        this.save(purchaseEntity);

        //获取新建采购单的id
        purchaseId = purchaseEntity.getId();

    }

    List<Long> items = mergeVo.getItems();

    //TODO 确认采购单状态是0,1才可以合并
    Collection<PurchaseDetailEntity> purchaseDetailEntities = purchaseDetailService.listByIds(items);

    purchaseDetailEntities.forEach((item) -> {
        if (!item.getStatus().equals(WareConstant.PurchaseDetailStatusEnum.CREATED.getCode())
            && !item.getStatus().equals(WareConstant.PurchaseDetailStatusEnum.ASSIGNED.getCode())) {
            throw new IllegalArgumentException("正在采购，无法进行分配");
        }
    });

    Long finalPurchaseId = purchaseId;
    List<PurchaseDetailEntity> collect = items.stream().map(i -> {
        PurchaseDetailEntity purchaseDetailEntity = new PurchaseDetailEntity();
        purchaseDetailEntity.setId(i);
        purchaseDetailEntity.setPurchaseId(finalPurchaseId);
        purchaseDetailEntity.setStatus(WareConstant.PurchaseDetailStatusEnum.ASSIGNED.getCode());
        return purchaseDetailEntity;
    }).collect(Collectors.toList());

    //批量修改
    purchaseDetailService.updateBatchById(collect);

    PurchaseEntity purchaseEntity = new PurchaseEntity();
    purchaseEntity.setId(purchaseId);
    purchaseEntity.setUpdateTime(new Date());
    this.updateById(purchaseEntity);
}

四、领取采购单

 /**
     * 领取采购单
     * @param ids 采购单的id
     */
    @Override
    public void received(List<Long> ids) {

        //1、确认当前采购单是新建或者是已分配状态
        List<PurchaseEntity> collect = ids.stream().map(id -> {
            PurchaseEntity byId = this.getById(id);
            return byId;
        }).filter(item -> {
            if (item.getStatus() == WareConstant.PurchaseStatusEnum.CREATED.getCode() ||
                    item.getStatus() == WareConstant.PurchaseStatusEnum.ASSIGNED.getCode()) {
                return true;
            }
            return false;
        }).map(item -> {
            //改变完状态的采购单
            item.setStatus(WareConstant.PurchaseStatusEnum.RECEIVE.getCode());
            item.setUpdateTime(new Date());
            return item;
        }).collect(Collectors.toList());

        //2、改变采购单的状态
        this.updateBatchById(collect);

        //3、改变采购项的状态
        collect.forEach((item) -> {
            List<PurchaseDetailEntity> list = purchaseDetailService.listDetailByPurchaseId(item.getId());
            List<PurchaseDetailEntity> detailEntities = list.stream().map(entity -> {

                PurchaseDetailEntity purchaseDetailEntity = new PurchaseDetailEntity();
                purchaseDetailEntity.setId(entity.getId());
                purchaseDetailEntity.setStatus(WareConstant.PurchaseDetailStatusEnum.BUYING.getCode());
                return purchaseDetailEntity;
            }).collect(Collectors.toList());
            purchaseDetailService.updateBatchById(detailEntities);

        });

    }

五、完成采购单

/**
 * 完成采购单
 * @param doneVo
 */
@Override
public void done(PurchaseDoneVo doneVo) {

    Long id = doneVo.getId();

    //1、改变采购项的状态
    Boolean flag = true;
    List<PurchaseItemDoneVo> items = doneVo.getItems();
    List<PurchaseDetailEntity> updates = new ArrayList<>();

    for (PurchaseItemDoneVo item : items) {
        PurchaseDetailEntity purchaseDetailEntity = new PurchaseDetailEntity();
        if (item.getStatus() == WareConstant.PurchaseDetailStatusEnum.HASERROR.getCode()) {
            flag = false;
            purchaseDetailEntity.setStatus(item.getStatus());
        } else {
            purchaseDetailEntity.setStatus(WareConstant.PurchaseDetailStatusEnum.FINISH.getCode());
            //3、将成功采购的进行入库
            //查出当前采购项的详细信息
            //PurchaseDetailEntity entity = purchaseDetailService.getById(item.getItemId());
            PurchaseDetailEntity entity = purchaseDetailService.getById(item.getItemId());
            wareSkuService.addStock(entity.getSkuId(),entity.getWareId(),entity.getSkuNum());

        }
        purchaseDetailEntity.setId(item.getItemId());

        updates.add(purchaseDetailEntity);
    }

    //批量更新
    purchaseDetailService.updateBatchById(updates);

    //2、改变采购单状态
    PurchaseEntity purchaseEntity = new PurchaseEntity();
    purchaseEntity.setId(id);
    purchaseEntity.setStatus(flag?WareConstant.PurchaseStatusEnum.FINISH.getCode():WareConstant.PurchaseStatusEnum.HASERROR.getCode());
    purchaseEntity.setUpdateTime(new Date());
    this.updateById(purchaseEntity);

}
