在网关配置路由转发

guligateway .yml配置文件

        - id: ware_route
          uri: lb://guliware
          predicates:
            - Path=/api/guliware/**
          filters:
            - RewritePath=/api/(?<segment>.*),/$\{segment}

解决仓库维护页面模糊查询功能

WareInfoController.java

    @RequestMapping("/list")
    public R list(@RequestParam Map<String, Object> params){
        PageUtils page = wareInfoService.queryPage(params);

        return R.ok().put("page", page);
    }

WareInfoController.java

    @Override
    public PageUtils queryPage(Map<String, Object> params) {
        QueryWrapper<WareInfoEntity> wareInfoEntityQueryWrapper = new QueryWrapper<>();
        String key = (String) params.get("key");
        if(!StringUtils.isEmpty(key)){
            wareInfoEntityQueryWrapper.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),
                wareInfoEntityQueryWrapper
        );

        return new PageUtils(page);
    }

查询库存&&创建采购需求

在这里插入图片描述

解决查询库存模糊查询问题

    @RequestMapping("/list")
    public R list(@RequestParam Map<String, Object> params){
        PageUtils page = wareSkuService.queryPage(params);

        return R.ok().put("page", page);
    }

 @Override
    public PageUtils queryPage(Map<String, Object> params) {
        /**
         * skuId: 1
         * wareId: 2
         */
        QueryWrapper<WareSkuEntity> queryWrapper = new QueryWrapper<>();
        String skuId = (String) params.get("skuId");
        if(!StringUtils.isEmpty(skuId)){
            queryWrapper.eq("sku_id",skuId);
        }

        String wareId = (String) params.get("wareId");
        if(!StringUtils.isEmpty(wareId)){
            queryWrapper.eq("ware_id",wareId);
        }


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

        return new PageUtils(page);
    }

创建采购需求-人工发出/自动化采购

解决采购需求模糊检索

    /**
     * 列表
     */
    @RequestMapping("/list")
    public R list(@RequestParam Map<String, Object> params){
        PageUtils page = purchaseDetailService.queryPage(params);

        return R.ok().put("page", page);
    }

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

        /**
         * status: 0,//状态
         *    wareId: 1,//仓库id
         */

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

        String key = (String) params.get("key");
        if(!StringUtils.isEmpty(key)){
            //purchase_id  sku_id
            queryWrapper.and(w->{
                w.eq("purchase_id",key).or().eq("sku_id",key);
            });
        }

        String status = (String) params.get("status");
        if(!StringUtils.isEmpty(status)){
            //purchase_id  sku_id
            queryWrapper.eq("status",status);
        }

        String wareId = (String) params.get("wareId");
        if(!StringUtils.isEmpty(wareId)){
            //purchase_id  sku_id
            queryWrapper.eq("ware_id",wareId);
        }

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

        return new PageUtils(page);
    }

合并采购单
在这里插入图片描述
1.查询未领取的采购单
PurchaseController.java

@RequestMapping("/unreceive/list")
    //@RequiresPermissions("ware:purchase:list") 分页查询
    public R unreceivelist(@RequestParam Map<String, Object> params){
        PageUtils page = purchaseService.queryPageUnreceivePurchase(params);

        return R.ok().put("page", page);
    }

PurchaseServiceImpl.java

    @Override
    public PageUtils queryPageUnreceivePurchase(Map<String, Object> params) {
        IPage<PurchaseEntity> page = this.page(
                new Query<PurchaseEntity>().getPage(params),
                new QueryWrapper<PurchaseEntity>().eq("status",0).or().eq("status",1)
        );

        return new PageUtils(page);
    }

2.合并采购需求有采购单则根据采购单合并，没有则创建新的采购单进行合并
创建mergeVo 包含采购项和采购单的id

@Data
public class MergeVo {

    private Long purchaseId; //整单id
    private List<Long> items;//[1,2,3,4] //合并项集合
}

PurchaseController.java

    @PostMapping("/merge")
    public R merge(@RequestBody MergeVo mergeVo){

        purchaseService.mergePurchase(mergeVo);
        return R.ok();
    }

PurchaseServiceImpl.java

@Transactional
    @Override
    public void mergePurchase(MergeVo mergeVo) {
        Long purchaseId = mergeVo.getPurchaseId();
        if(purchaseId == null){
            //1、如果没有采购单 新建一个
            PurchaseEntity purchaseEntity = new PurchaseEntity();

            purchaseEntity.setStatus(WareConstant.PurchaseStatusEnum.CREATED.getCode());
            purchaseEntity.setCreateTime(new Date());
            purchaseEntity.setUpdateTime(new Date());
            this.save(purchaseEntity);
            purchaseId = purchaseEntity.getId();
        }

        //TODO 确认采购单状态是0,1才可以合并

        List<Long> items = mergeVo.getItems();
        Long finalPurchaseId = purchaseId;
        List<PurchaseDetailEntity> collect = items.stream().map(i -> {
            PurchaseDetailEntity detailEntity = new PurchaseDetailEntity();

            detailEntity.setId(i);
            detailEntity.setPurchaseId(finalPurchaseId);
            //设置状态码
            detailEntity.setStatus(WareConstant.PurchaseDetailStatusEnum.ASSIGNED.getCode());
            return detailEntity;
        }).collect(Collectors.toList());

        //批量改变订单状态
        detailService.updateBatchById(collect);
        //更新修改时间
        PurchaseEntity purchaseEntity = new PurchaseEntity();
        purchaseEntity.setId(purchaseId);
        purchaseEntity.setUpdateTime(new Date());

        this.updateById(purchaseEntity);
    }

3.采购人员（员工端APP）领取采购单
PurchaseController.java

    /**
     * 领取采购单
     *List<Long> ids 要领取的采购单的id
     */
    @PostMapping("/received")
    public R received(@RequestBody List<Long> ids){

        purchaseService.received(ids);

        return R.ok();
    }

PurchaseServiceImpl.java

/**
     *
     * @param ids 采购单id
     */
    @Override
    public void received(List<Long> ids) {
        //1、确认当前采购单是新建或者已分配状态
        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->{
            //设置最新的被领取的状态
            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
        //根据每个采购单id找到具体采购项
        collect.forEach((item)->{
            List<PurchaseDetailEntity> entities = detailService.listDetailByPurchaseId(item.getId());
            List<PurchaseDetailEntity> detailEntities = entities.stream().map(entity -> {
                PurchaseDetailEntity entity1 = new PurchaseDetailEntity();
                entity1.setId(entity.getId());
                entity1.setStatus(WareConstant.PurchaseDetailStatusEnum.BUYING.getCode());
                return entity1;
            }).collect(Collectors.toList());
            detailService.updateBatchById(detailEntities);
        });
    }

PurchaseDetailServiceImpl.java

    @Override
    public List<PurchaseDetailEntity> listDetailByPurchaseId(Long id) {

        List<PurchaseDetailEntity> purchaseId = this.list(new QueryWrapper<PurchaseDetailEntity>().eq("purchase_id", id));

        return purchaseId;
    }

在这里插入图片描述

3.完成采购功能
PurchaseController.java

 @PostMapping("/done")
    public R finish(@RequestBody PurchaseDoneVo doneVo){

        purchaseService.done(doneVo);

        return R.ok();
    }

创建相关Vo PurchaseDoneVo PurchaseItemDoneVo
PurchaseServiceImpl.java

在这里插入代码片

WareSkuServiceImpl.java
向仓库里加入采购的商品

配置商品服务分页插件

@EnableTransactionManagement
@MapperScan("com/edu/npu/gulimall/guliware/dao")
@Configuration
public class WareMyBatisConfig {

    //引入分页插件
    @Bean
    public PaginationInterceptor paginationInterceptor() {
        PaginationInterceptor paginationInterceptor = new PaginationInterceptor();
        // 设置请求的页面大于最大页后操作， true调回到首页，false 继续请求  默认false
//        paginationInterceptor.setOverflow(true);
//        // 设置最大单页限制数量，默认 500 条，-1 不受限制
//        paginationInterceptor.setLimit(1000);
        return paginationInterceptor;
    }
}

调用远程服务获取新增商品的名称

@FeignClient("guliproduct")
public interface ProductFeignService {

    /**
     *      /product/skuinfo/info/{skuId}
     *
     *
     *   1)、让所有请求过网关；
     *          1、@FeignClient("guligateway")：给guligateway所在的机器发请求
     *          2、/api/guliproduct/skuinfo/info/{skuId}
     *   2）、直接让后台指定服务处理
     *          1、@FeignClient("guliproduct")
     *          2、/guliproduct/skuinfo/info/{skuId}
     *
     * @return
     */
    @RequestMapping("/guliproduct/skuinfo/info/{skuId}")
    public R info(@PathVariable("skuId") Long skuId);
}

改变采购后的商品库存

    @Override
    public void addStock(Long skuId, Long wareId, Integer skuNum) {
        //1、判断如果还没有这个库存记录 -> 新增操作
        List<WareSkuEntity> entities = wareSkuDao.selectList(new QueryWrapper<WareSkuEntity>().eq("sku_id", skuId).eq("ware_id", wareId));
        if(entities == null || entities.size() == 0){
            WareSkuEntity skuEntity = new WareSkuEntity();
            skuEntity.setSkuId(skuId);
            skuEntity.setStock(skuNum);
            skuEntity.setWareId(wareId);
            skuEntity.setStockLocked(0);
            //TODO 远程查询sku的名字，如果失败，整个事务无需回滚
            //1、自己catch异常
            //TODO 还可以用什么办法让异常出现以后不回滚？高级
            try {
                R info = productFeignService.info(skuId);
                Map<String,Object> data = (Map<String, Object>) info.get("skuInfo");

                if(info.getCode() == 0){
                    skuEntity.setSkuName((String) data.get("skuName"));
                }
            }catch (Exception e){

            }


            wareSkuDao.insert(skuEntity);
        }else{
            wareSkuDao.addStock(skuId,wareId,skuNum);
        }
    }
