十、新增商品--谷粒商城

发布时间 2023-06-20 16:32:26作者: 93丶Fss

一、新增商品-调试会员等级相关接口

 编写路由规则 
  - id: member_route
         uri: lb://gulimall-member
         predicates:
           - Path=/api/member/**
         filters:
           - RewritePath=/api/(?<segment>.*),/$\{segment}

导入你代码生成的vue界面

 

二、新增商品-获取分类关联的品牌

controller

    /**
     *  /product/categorybrandrelation/brands/list
     *
     *  1、Controller：处理请求，接受和校验数据
     *  2、Service接受controller传来的数据，进行业务处理
     *  3、Controller接受Service处理完的数据，封装页面指定的vo
     */
    @GetMapping("/brands/list")
    public R relationBrandsList(@RequestParam(value = "catId",required = true)Long catId){
        //1 接受请求拿到传来的目录Id
        //2 调用categoryBrandRelationService的自定义方法获取BrandEntity
        List<BrandEntity> vos = categoryBrandRelationService.getBrandsByCatId(catId);

        //3 把BrandEntity进行处理封装成前端需要的BrandVo返回
        List<BrandVo> collect = vos.stream().map(item -> {
            BrandVo brandVo = new BrandVo();
            brandVo.setBrandId(item.getBrandId());
            brandVo.setBrandName(item.getName());

            return brandVo;
        }).collect(Collectors.toList());

        return R.ok().put("data",collect);

    }

service

List<BrandEntity> getBrandsByCatId(Long catId);

serviceImpl

   /**
     * 根据一个分类id查询和他有关的所有品牌实体类
     * @param catId
     * @return
     */
    @Override
    public List<BrandEntity> getBrandsByCatId(Long catId) {

        //1 首先根据分类catId查出CategoryBrandRelation表中所有关联数据
        List<CategoryBrandRelationEntity> catelogId = relationDao.selectList(new QueryWrapper<CategoryBrandRelationEntity>().eq("catelog_id", catId));
        //2 根据CategoryBrandRelationEntity 的 List 查出 brand list
        List<BrandEntity> collect = catelogId.stream().map(item -> {
            //2.1 对于每一个CategoryBrandRelationEntity 先拿出其BrandId
            Long brandId = item.getBrandId();
            //2.2 用其BrandId 调用 brandService拿到brand实体类
            BrandEntity byId = brandService.getById(brandId);
            return byId;
        }).collect(Collectors.toList());

        //3 最终返回结果
        return collect;
    }

三、新增商品- 获取分类下所有分组和属性

AttrGroupController

///product/attrgroup/{catelogId}/withattr
    @GetMapping("/{catelogId}/withattr")
    public R getAttrGroupWithAttrs(@PathVariable("catelogId")Long catelogId){

        //1、查出当前分类下的所有属性分组，
        //2、查出每个属性分组的所有属性
        List<AttrGroupWithAttrsVo> vos =  attrGroupService.getAttrGroupWithAttrsByCatelogId(catelogId);
        return R.ok().put("data",vos);
    }

service

public interface AttrGroupService extends IService<AttrGroupEntity> {

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

    PageUtils queryPage(Map<String, Object> params, Long catelogId);

    List<AttrGroupWithAttrsVo> getAttrGroupWithAttrsByCatelogId(Long catelogId);
}

serviceimpl

 /**
     * 根据分类id查出所有的分组以及这些组里面的属性
     * @param catelogId
     * @return
     */
    @Override
    public List<AttrGroupWithAttrsVo> getAttrGroupWithAttrsByCatelogId(Long catelogId) {
        //com.atguigu.gulimall.product.vo
        //1、查询分组信息(列出所有与目录ID相关的分组)
        List<AttrGroupEntity> attrGroupEntities = this.list(new QueryWrapper<AttrGroupEntity>().eq("catelog_id", catelogId));

        //2、查询所有属性
        List<AttrGroupWithAttrsVo> collect = attrGroupEntities.stream().map(group -> {
            //创建一个返回VO
            AttrGroupWithAttrsVo attrsVo = new AttrGroupWithAttrsVo();
            //copy属性
            BeanUtils.copyProperties(group,attrsVo);
            //根据分组ID得到对应的属性函数
            List<AttrEntity> attrs = attrService.getRelationAttr(attrsVo.getAttrGroupId());
            //把得到的对应属性赋值到VO中
            attrsVo.setAttrs(attrs);
            return attrsVo;
        }).collect(Collectors.toList());

        return collect;


    }

四、新增商品-新增商品VO抽取

@Data
public class BaseAttrs {
    private Long attrId;
    private String attrValues;
    private int showDesc;
}

五、新增商品 保存SPU与SKU基本信息

大概思路：stream流处理好数据之后直接调serverce用mybatis-plus进行数据保存

SpuInfoServiceImpl

@Transactional
    @Override
    public void saveSpuInfo(SpuSaveVo vo) {

        //1、保存spu基本信息 pms_spu_info
        SpuInfoEntity infoEntity = new SpuInfoEntity();
        BeanUtils.copyProperties(vo,infoEntity);
        infoEntity.setCreateTime(new Date());
        infoEntity.setUpdateTime(new Date());
        this.saveBaseSpuInfo(infoEntity);

        //2、保存Spu的描述图片 pms_spu_info_desc
        List<String> decript = vo.getDecript();
        SpuInfoDescEntity descEntity = new SpuInfoDescEntity();
        descEntity.setSpuId(infoEntity.getId());
        descEntity.setDecript(String.join(",",decript));
        spuInfoDescService.saveSpuInfoDesc(descEntity);



        //3、保存spu的图片集 pms_spu_images
        List<String> images = vo.getImages();
        imagesService.saveImages(infoEntity.getId(),images);


        //4、保存spu的规格参数;pms_product_attr_value
        List<BaseAttrs> baseAttrs = vo.getBaseAttrs();
        List<ProductAttrValueEntity> collect = baseAttrs.stream().map(attr -> {
            ProductAttrValueEntity valueEntity = new ProductAttrValueEntity();
            valueEntity.setAttrId(attr.getAttrId());
            AttrEntity id = attrService.getById(attr.getAttrId());
            valueEntity.setAttrName(id.getAttrName());
            valueEntity.setAttrValue(attr.getAttrValues());
            valueEntity.setQuickShow(attr.getShowDesc());
            valueEntity.setSpuId(infoEntity.getId());

            return valueEntity;
        }).collect(Collectors.toList());
        attrValueService.saveProductAttr(collect);


        //5、保存spu的积分信息；gulimall_sms->sms_spu_bounds
        Bounds bounds = vo.getBounds();
        SpuBoundTo spuBoundTo = new SpuBoundTo();
        BeanUtils.copyProperties(bounds,spuBoundTo);
        spuBoundTo.setSpuId(infoEntity.getId());
        R r = couponFeignService.saveSpuBounds(spuBoundTo);
        if(r.getCode() != 0){
            log.error("远程保存spu积分信息失败");
        }


        //5、保存当前spu对应的所有sku信息；

        List<Skus> skus = vo.getSkus();
        if(skus!=null && skus.size()>0){
            skus.forEach(item->{
                String defaultImg = "";
                for (Images image : item.getImages()) {
                    if(image.getDefaultImg() == 1){
                        defaultImg = image.getImgUrl();
                    }
                }
                //    private String skuName;
                //    private BigDecimal price;
                //    private String skuTitle;
                //    private String skuSubtitle;
                SkuInfoEntity skuInfoEntity = new SkuInfoEntity();
                BeanUtils.copyProperties(item,skuInfoEntity);
                skuInfoEntity.setBrandId(infoEntity.getBrandId());
                skuInfoEntity.setCatalogId(infoEntity.getCatalogId());
                skuInfoEntity.setSaleCount(0L);
                skuInfoEntity.setSpuId(infoEntity.getId());
                skuInfoEntity.setSkuDefaultImg(defaultImg);
                //5.1）、sku的基本信息；pms_sku_info
                skuInfoService.saveSkuInfo(skuInfoEntity);

                Long skuId = skuInfoEntity.getSkuId();

                List<SkuImagesEntity> imagesEntities = item.getImages().stream().map(img -> {
                    SkuImagesEntity skuImagesEntity = new SkuImagesEntity();
                    skuImagesEntity.setSkuId(skuId);
                    skuImagesEntity.setImgUrl(img.getImgUrl());
                    skuImagesEntity.setDefaultImg(img.getDefaultImg());
                    return skuImagesEntity;
                }).filter(entity->{
                    //返回true就是需要，false就是剔除
                    return !StringUtils.isEmpty(entity.getImgUrl());
                }).collect(Collectors.toList());
                //5.2）、sku的图片信息；pms_sku_image
                skuImagesService.saveBatch(imagesEntities);
                //TODO 没有图片路径的无需保存

                List<Attr> attr = item.getAttr();
                List<SkuSaleAttrValueEntity> skuSaleAttrValueEntities = attr.stream().map(a -> {
                    SkuSaleAttrValueEntity attrValueEntity = new SkuSaleAttrValueEntity();
                    BeanUtils.copyProperties(a, attrValueEntity);
                    attrValueEntity.setSkuId(skuId);

                    return attrValueEntity;
                }).collect(Collectors.toList());
                //5.3）、sku的销售属性信息：pms_sku_sale_attr_value
                skuSaleAttrValueService.saveBatch(skuSaleAttrValueEntities);

                // //5.4）、sku的优惠、满减等信息；gulimall_sms->sms_sku_ladder\sms_sku_full_reduction\sms_member_price
                SkuReductionTo skuReductionTo = new SkuReductionTo();
                BeanUtils.copyProperties(item,skuReductionTo);
                skuReductionTo.setSkuId(skuId);
                if(skuReductionTo.getFullCount() >0 || skuReductionTo.getFullPrice().compareTo(new BigDecimal("0")) == 1){
                    R r1 = couponFeignService.saveSkuReduction(skuReductionTo);
                    if(r1.getCode() != 0){
                        log.error("远程保存sku优惠信息失败");
                    }
                }
            });
        }

六、新增商品 调用远程服务保存优惠等信息

feingn定义

CouponFeignService

@FeignClient("gulimall-coupon")
public interface CouponFeignService {


    /**
     * 1、CouponFeignService.saveSpuBounds(spuBoundTo);
     *      1）、@RequestBody将这个对象转为json。
     *      2）、找到gulimall-coupon服务，给/coupon/spubounds/save发送请求。
     *          将上一步转的json放在请求体位置，发送请求；
     *      3）、对方服务收到请求。请求体里有json数据。
     *          (@RequestBody SpuBoundsEntity spuBounds)；将请求体的json转为SpuBoundsEntity；
     * 只要json数据模型是兼容的。双方服务无需使用同一个to
     * @param spuBoundTo
     * @return
     */
    @PostMapping("/coupon/spubounds/save")
    R saveSpuBounds(@RequestBody SpuBoundTo spuBoundTo);


    @PostMapping("/coupon/skufullreduction/saveinfo")
    R saveSkuReduction(@RequestBody SkuReductionTo skuReductionTo);
}

coppon服务

 @Override
    public void saveSkuReduction(SkuReductionTo reductionTo) {
        //1、// //5.4）、sku的优惠、满减等信息；gulimall_sms->sms_sku_ladder\sms_sku_full_reduction\sms_member_price
        //sms_sku_ladder
        SkuLadderEntity skuLadderEntity = new SkuLadderEntity();

        skuLadderEntity.setDiscount(reductionTo.getDiscount());
        skuLadderEntity.setAddOther(reductionTo.getCountStatus());
        if(reductionTo.getFullCount() > 0){
            skuLadderService.save(skuLadderEntity);
        }




        //2、sms_sku_full_reduction
        SkuFullReductionEntity reductionEntity = new SkuFullReductionEntity();
        BeanUtils.copyProperties(reductionTo,reductionEntity);
        if(reductionEntity.getFullPrice().compareTo(new BigDecimal("0"))==1){
            this.save(reductionEntity);
        }


        //3、sms_member_price
        List<MemberPrice> memberPrice = reductionTo.getMemberPrice();

        List<MemberPriceEntity> collect = memberPrice.stream().map(item -> {

            priceEntity.setMemberLevelName(item.getName());
            priceEntity.setMemberPrice(item.getPrice());
            priceEntity.setAddOther(1);
            return priceEntity;
        }).filter(item->{
            return item.getMemberPrice().compareTo(new BigDecimal("0")) == 1;
        }).collect(Collectors.toList());

        memberPriceService.saveBatch(collect);
    }
SkuFullReductionServiceImpl
@Service("skuFullReductionService")
public class SkuFullReductionServiceImpl extends ServiceImpl<SkuFullReductionDao, SkuFullReductionEntity> implements SkuFullReductionService {

    @Autowired
    SkuLadderService skuLadderService;

    @Autowired
    MemberPriceService memberPriceService;


    @Override
    public PageUtils queryPage(Map<String, Object> params) {
        IPage<SkuFullReductionEntity> page = this.page(
                new Query<SkuFullReductionEntity>().getPage(params),
                new QueryWrapper<SkuFullReductionEntity>()
        );

        return new PageUtils(page);
    }

    @Override
    public void saveSkuReduction(SkuReductionTo reductionTo) {
        //1、// //6.4）、sku的优惠、满减等信息；gulimall_sms->sms_sku_ladder\sms_sku_full_reduction\sms_member_price
        //sms_sku_ladder
        SkuLadderEntity skuLadderEntity = new SkuLadderEntity();
        skuLadderEntity.setSkuId(reductionTo.getSkuId());
        skuLadderEntity.setFullCount(reductionTo.getFullCount());
        skuLadderEntity.setDiscount(reductionTo.getDiscount());
        skuLadderEntity.setAddOther(reductionTo.getCountStatus());
        if(reductionTo.getFullCount() > 0){
            skuLadderService.save(skuLadderEntity);
        }


        //2、sms_sku_full_reduction

        }


        //3、sms_member_price
        List<MemberPrice> memberPrice = reductionTo.getMemberPrice();
        List<MemberPriceEntity> collect = memberPrice.stream().map(item -> {
            MemberPriceEntity priceEntity = new MemberPriceEntity();
            priceEntity.setSkuId(reductionTo.getSkuId());
            priceEntity.setMemberLevelId(item.getId());
            priceEntity.setMemberLevelName(item.getName());
            priceEntity.setMemberPrice(item.getPrice());
            priceEntity.setAddOther(1);
            return priceEntity;
        }).filter(item->{
            return item.getMemberPrice().compareTo(new BigDecimal("0")) == 1;
        }).collect(Collectors.toList());

        memberPriceService.saveBatch(collect);
    }


}

七、SPU检索

controller

 @RequestMapping("/list")
    //@RequiresPermissions("product:spuinfo:list")
    public R list(@RequestParam Map<String, Object> params){
        PageUtils page = spuInfoService.queryPageByCondition(params);

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

service

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

serviceimpl

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

        QueryWrapper<SpuInfoEntity> wrapper = new QueryWrapper<>();

        String key = (String) params.get("key");
        if(!StringUtils.isEmpty(key)){
            wrapper.and((w)->{
                w.eq("id",key).or().like("spu_name",key);
            });
        }
        // status=1 and (id=1 or spu_name like xxx)
        String status = (String) params.get("status");
        if(!StringUtils.isEmpty(status)){
            wrapper.eq("publish_status",status);
        }

        String brandId = (String) params.get("brandId");
        if(!StringUtils.isEmpty(brandId)&&!"0".equalsIgnoreCase(brandId)){

        if(!StringUtils.isEmpty(catelogId)&&!"0".equalsIgnoreCase(catelogId)){
            wrapper.eq("catalog_id",catelogId);
        }

        /**
         * status: 2
         * key:
         * brandId: 9
         * catelogId: 225
         */

        IPage<SpuInfoEntity> page = this.page(
                new Query<SpuInfoEntity>().getPage(params),
                wrapper
        );

        return new PageUtils(page);
    }

八、SKU检索

 controller 
@RequestMapping("/list")
    //@RequiresPermissions("product:skuinfo:list")
    public R list(@RequestParam Map<String, Object> params){
        PageUtils page = skuInfoService.queryPageByCondition(params);

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

service

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

serviceimpl

@Override
    public PageUtils queryPageByCondition(Map<String, Object> params) {
        QueryWrapper<SkuInfoEntity> queryWrapper = new QueryWrapper<>();
        /**
         * key:
         * catelogId: 0
         * brandId: 0
         * min: 0
         * max: 0
         */
        String key = (String) params.get("key");
        if(!StringUtils.isEmpty(key)){
            queryWrapper.and((wrapper)->{
                wrapper.eq("sku_id",key).or().like("sku_name",key);
            });
        }

        String catelogId = (String) params.get("catelogId");
        if(!StringUtils.isEmpty(catelogId)&&!"0".equalsIgnoreCase(catelogId)){

            queryWrapper.eq("catalog_id",catelogId);
        }

        String brandId = (String) params.get("brandId");
        if(!StringUtils.isEmpty(brandId)&&!"0".equalsIgnoreCase(catelogId)){
            queryWrapper.eq("brand_id",brandId);
        }

        String min = (String) params.get("min");
        if(!StringUtils.isEmpty(min)){
            queryWrapper.ge("price",min);
        }

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

        if(!StringUtils.isEmpty(max)  ){
            try{
                BigDecimal bigDecimal = new BigDecimal(max);

                if(bigDecimal.compareTo(new BigDecimal("0"))==1){
                    queryWrapper.le("price",max);
                }
            }catch (Exception e){

            }

        }


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

        return new PageUtils(page);
    }
