仓库管理（库存系统模块）

库存系统

整合ware服务

spring:
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848
  application:
    name: gulimall-ware

• 主启动：

• @EnableDiscoveryClient

• @MapperScan("com.wlq.gulimall.ware.dao")

• @EnableTransactionManagement

• 配置网关

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

• 配置分页插件：com.wlq.gulimall.ware.config.WareMyBatisConfig

@EnableTransactionManagement
@MapperScan("com.atguigu.gulimall.ware.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;
    }
}

• 启动ware服务

1、仓库维护

• 测试仓库维护的新增、删除、修改功能
  

• 修改WareInfoServiceImpl，增加模糊检索功能

@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);
    }

• 测试
  

2、商品库存

• /ware/waresku/list

1、查询修改

• 修改它的实现方法：WareSkuServiceImpl

@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);
    }

• 测试
  

3、采购单维护

1、给库存添加商品应该是从采购单进行添加

商品库存里的新增只是为了测试方便

2、新建一个采购需求

2、完善采购需求的模糊检索

• /ware/purchasedetail/list
• 修改PurchaseDetailServiceImpl

@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);
    }

• 测试
  
  

3、合并采购需求

1、新增采购单

分配一个采购人员

2、查询未领取的采购单

• /ware/purchase/unreceive/list

• PurchaseController

	/**
     * 查询未领取的采购单
     */
    @RequestMapping("/unreceive/list")
    //@RequiresPermissions("ware:purchase:list")
    public R unreceivelist(@RequestParam Map<String, Object> params){
        PageUtils page = purchaseService.queryPageUnreceivePurchase(params);

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

• service

PageUtils queryPageUnreceivePurchase(Map<String, Object> params);

• impl

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);
    }

• 测试
  

3、合并采购需求

• /ware/purchase/merge
• 新建VO：com.wlq.gulimall.ware.vo.MergeVo

@Data
public class MergeVo {
    /**
     * purchaseId   //整单id
     * items        //[1,2,3,4] 合并项集合
     */
    private Long purchaseId;
    private List<Long> items;
}

• PurchaseController

/**
     * 合并采购需求
     * @param mergeVo
     * @return
     */
    ///ware/purchase/merge
    @PostMapping("/merge")
    public R merge(@RequestBody MergeVo mergeVo){

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

• service

void mergePurchase(MergeVo mergeVo);

• common下新建：com.wlq.common.constant.WareConstant

public class WareConstant {

    public enum  PurchaseStatusEnum{
        CREATED(0,"新建"),ASSIGNED(1,"已分配"),
        RECEIVE(2,"已领取"),FINISH(3,"已完成"),
        HASERROR(4,"有异常");
        private int code;
        private String msg;

        PurchaseStatusEnum(int code,String msg){
            this.code = code;
            this.msg = msg;
        }

        public int getCode() {
            return code;
        }

        public String getMsg() {
            return msg;
        }
    }


    public enum  PurchaseDetailStatusEnum{
        CREATED(0,"新建"),ASSIGNED(1,"已分配"),
        BUYING(2,"正在采购"),FINISH(3,"已完成"),
        HASERROR(4,"采购失败");
        private int code;
        private String msg;

        PurchaseDetailStatusEnum(int code,String msg){
            this.code = code;
            this.msg = msg;
        }

        public int getCode() {
            return code;
        }

        public String getMsg() {
            return msg;
        }
    }
}

• impl

@Transactional
    @Override
    public void mergePurchase(MergeVo mergeVo) {
        Long purchaseId = mergeVo.getPurchaseId();
        if(purchaseId == null){
            //1、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);
            detailEntity.setStatus(WareConstant.PurchaseDetailStatusEnum.ASSIGNED.getCode());
            return detailEntity;
        }).collect(Collectors.toList());


        detailService.updateBatchById(collect);

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

• 测试合并整单
  
• 对比未合单之前
  

4、领取采购单

postman模拟手机接单，领取采购单

• /ware/purchase/received

• PurchaseController

/**
     * 领取采购单
     * @return
     */
    @PostMapping("/received")
    public R received(@RequestBody List<Long> ids){

        purchaseService.received(ids);

        return R.ok();
    }

• service

void received(List<Long> ids);

• impl

/**
     *
     * @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->{
            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> 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);
        });
    }

• listDetailByPurchaseId 方法实现
• service

List<PurchaseDetailEntity> listDetailByPurchaseId(Long id);

• impl : PurchaseDetailServiceImpl

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

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

        return purchaseId;
    }

postman模拟领取采购单

• 方送请求
  

• 查看采购需求，采购单
  
  

5、完成采购

• /ware/purchase/done

• 新建Vo

• PurchaseDoneVo

@Data
public class PurchaseDoneVo {

    @NotNull
    private Long id;//采购单id

    private List<PurchaseItemDoneVo> items;
}

• PurchaseItemDoneVo

@Data
public class PurchaseItemDoneVo {
    //{itemId:1,status:4,reason:""}
    private Long itemId;
    private Integer status;
    private String reason;
}

• PurchaseController

/**
     * 完成采购单
     */
    ///ware/purchase/done
    @PostMapping("/done")
    public R finish(@RequestBody PurchaseDoneVo doneVo){

        purchaseService.done(doneVo);

        return R.ok();
    }

• service

void done(PurchaseDoneVo doneVo);

• impl

@Transactional
    @Override
    public void done(PurchaseDoneVo doneVo) {

        Long id = doneVo.getId();


        //2、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 detailEntity = new PurchaseDetailEntity();
            if(item.getStatus() == WareConstant.PurchaseDetailStatusEnum.HASERROR.getCode()){
                flag = false;
                detailEntity.setStatus(item.getStatus());
            }else{
                detailEntity.setStatus(WareConstant.PurchaseDetailStatusEnum.FINISH.getCode());
                3、将成功采购的进行入库
                PurchaseDetailEntity entity = detailService.getById(item.getItemId());
                wareSkuService.addStock(entity.getSkuId(),entity.getWareId(),entity.getSkuNum());

            }
            detailEntity.setId(item.getItemId());
            updates.add(detailEntity);
        }

        detailService.updateBatchById(updates);

        //1、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);


    }

addStock方法实现

• service

void addStock(Long skuId, Long wareId, Integer skuNum);

• impl

@Autowired
    WareSkuDao wareSkuDao;

• WareSkuDao

@Mapper
public interface WareSkuDao extends BaseMapper<WareSkuEntity> {

    void addStock(@Param("skuId") Long skuId, @Param("wareId") Long wareId, @Param("skuNum") Integer skuNum);
}

• xml

<mapper namespace="com.wlq.gulimall.ware.dao.WareSkuDao">

	
    <resultMap type="com.wlq.gulimall.ware.entity.WareSkuEntity" id="wareSkuMap">
        <result property="id" column="id"/>
        <result property="skuId" column="sku_id"/>
        <result property="wareId" column="ware_id"/>
        <result property="stock" column="stock"/>

• ProductFeignService

@FeignClient("gulimall-product")
public interface ProductFeignService {

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

• 主启动

@SpringBootApplication
@EnableDiscoveryClient
@EnableFeignClients(basePackages = "com.wlq.gulimall.ware.feign")
@MapperScan("com.wlq.gulimall.ware.dao")
public class GulimallWareApplication {

    public static void main(String[] args) {
        SpringApplication.run(GulimallWareApplication.class, args);
    }

}

• postman测试

4、完善商品管理的spu规格维护

1、获取spu规格，并回显

• /product/attr/base/listforspu/{spuId}

如果点击规格出现404

/src/router/index.js 在mainRoutes->children【】里面加上这个就不会404了：{ path: ‘/product-attrupdate’, component: _import(‘modules/product/attrupdate’), name: ‘attr-update’, meta: { title: ‘规格维护’, isTab: true } }

• 修改product服务的AttrController

/**
     * 获取spu规格
     * @param spuId
     * @return
     */
    // /product/attr/base/listforspu/{spuId}
    @GetMapping("/base/listforspu/{spuId}")
    public R baseAttrlistforspu(@PathVariable("spuId") Long spuId){

        List<ProductAttrValueEntity> entities = productAttrValueService.baseAttrlistforspu(spuId);

        return R.ok().put("data",entities);
    }

• ProductAttrValueService

List<ProductAttrValueEntity> baseAttrlistforspu(Long spuId);

• impl

@Override
    public List<ProductAttrValueEntity> baseAttrlistforspu(Long spuId) {
        List<ProductAttrValueEntity> entities = this.baseMapper.selectList(new QueryWrapper<ProductAttrValueEntity>().eq("spu_id", spuId));
        return entities;
    }

• 测试
  

2、修改参数的保存方法（添加批量保存方法）

• AttrController

/**
     * 批量保存
     */
    ///product/attr/update/{spuId}
    @PostMapping("/update/{spuId}")
    public R updateSpuAttr(@PathVariable("spuId") Long spuId,
                           @RequestBody List<ProductAttrValueEntity> entities){

        productAttrValueService.updateSpuAttr(spuId,entities);

        return R.ok();
    }

• ProductAttrValueService

void updateSpuAttr(Long spuId, List<ProductAttrValueEntity> entities);

• impl

@Transactional
    @Override
    public void updateSpuAttr(Long spuId, List<ProductAttrValueEntity> entities) {
        //1、删除这个spuId之前对应的所有属性
        this.baseMapper.delete(new QueryWrapper<ProductAttrValueEntity>().eq("spu_id",spuId));


        List<ProductAttrValueEntity> collect = entities.stream().map(item -> {
            item.setSpuId(spuId);
            return item;
        }).collect(Collectors.toList());
        this.saveBatch(collect);
    }

• 测试
  

确定修改后查看，回显修改后的数据成功
