谷粒商城分布式基础（十一）—— 仓储服务API—仓库管理

一、仓储服务

1、整合ware服务

（1）将gulimall-ware（仓储服务）加到注册中心nacos中
　　（a）修改application.yml

　　（b）开启服务注册发现功能

　　　　顺便开启事务注解

　　（c）启动gulimall-ware，观察nacos-server 

　　至此，服务注册成功 

　　注意：启动报错是配置中心的错误，暂时全部不用管，后期统一处理

（2）配置网关路由
　　修改gulimall-gateway的application.yml

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

　　修改完毕后，重启网关服务，查看

2、获取仓库列表

（1）修改gulimall-ware的application.yml，设置日志打印级别

 （2）修改com.atguigu.gulimall.ware.service.impl.WareInfoServiceImpl 的 queryPage 方法

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

3、查询库存

（1）修改com.atguigu.gulimall.ware.service.impl.WareSkuServiceImpl的 queryPage 方法

@Override
public PageUtils queryPage(Map<String, Object> params) {
    QueryWrapper<WareSkuEntity> wrapper = new QueryWrapper<>();
    String skuId = (String) params.get("skuId");
    if(!StringUtils.isEmpty(skuId)){
        wrapper.eq("sku_id",skuId);
    }
    String wareId = (String) params.get("wareId");
    if(!StringUtils.isEmpty(wareId)){
        wrapper.eq("ware_id",wareId);
    }
    IPage<WareSkuEntity> page = this.page(
            new Query<WareSkuEntity>().getPage(params),
            wrapper
    );
    return new PageUtils(page);
}

4、查询采购需求

（1）修改com.atguigu.gulimall.ware.service.impl.PurchaseDetailServiceImpl的 queryPage 方法

@Override
public PageUtils queryPage(Map<String, Object> params) {
    QueryWrapper<PurchaseDetailEntity> wrapper = new QueryWrapper<>();
    String key = (String) params.get("key");
    if(!StringUtils.isEmpty(key)){
        wrapper.and(w->{
            w.eq("purchase_id",key).or().eq("sku_id",key);
        });
    }
    String status = (String) params.get("status");
    if(!StringUtils.isEmpty(status)){
        wrapper.eq("status",status);
    }
    String wareId = (String) params.get("wareId");
    if(!StringUtils.isEmpty(wareId)){
        wrapper.eq("ware_id",wareId);
    }
    IPage<PurchaseDetailEntity> page = this.page(
            new Query<PurchaseDetailEntity>().getPage(params),
            wrapper
    );
    return new PageUtils(page);
}

5、合并采购需求

（1）采购简要流程

 

（2）查询未领取的采购单
　　（a）com.atguigu.gulimall.ware.controller.PurchaseController 新加方法 unreceivelist

/**
 * 查询未领取的采购单
 * @param params
 * @return
 */
///ware/purchase/unreceive/list
@RequestMapping("/unreceive/list")
//@RequiresPermissions("ware:purchase:list")
public R unreceivelist(@RequestParam Map<String, Object> params){
    PageUtils page = purchaseService.queryUnreceivePage(params);
    return R.ok().put("page", page);
}
　　（b）新增接口和实现方法 queryUnreceivePage

/**
 * 查询未领取的采购单
 * @param params
 * @return
 */
@Override
public PageUtils queryUnreceivePage(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);
}
效果

（3）合并采购需求
　　（a）gulimall-common 新增文件 com.atguigu.common.constant.WareConstant

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

        public int getCode() {
            return code;
        }

        public String getMsg() {
            return msg;
        }
    }

        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或者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);

 */
@Override
@Transactional
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 -> {

        // 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);
        // 开启 count 的 join 优化,只针对部分 left join
        paginationInterceptor.setCountSqlParser(new JsqlParserCountOptimize(true));

        //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);

二、商品管理

1、SPU规格维护

（1）解决spu管理规格点击404

　　点规格，404，前端改一下：

 　/src/router/index.js 在mainRoutes->children【】里面加上：

　　{ path: '/product-attrupdate', component: _import('modules/product/attrupdate'), name: 'attr-update', meta: { title: '规格维护', isTab: true } }

　　修改后：

（2）获取spu规格
　　（a）com.atguigu.gulimall.product.controller.AttrController 新增方法 baseAttrlistforspu

/**
 * 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);
}
　　（b）新增接口和实现类方法 baseAttrlistforspu

/**
 * 获取spu规格
 * @param spuId
 * @return
 */
@Override
public List<ProductAttrValueEntity> baseAttrlistforspu(Long spuId) {
    List<ProductAttrValueEntity> spu_id = this.baseMapper.selectList(new QueryWrapper<ProductAttrValueEntity>().eq("spu_id", spuId));

    productAttrValueService.updateSpuAttr(spuId, entities);
    return R.ok();
}
　　（b）新增接口和实现类方法

@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

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