谷粒商城-商品服务-新增商品功能开发（商品图片无法展示问题没有解决）

在网关配置路由

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

并将所有逆向生成的工程调式出来

获取分类关联的品牌

例如：手机（分类）-> 品牌(华为)
CategoryBrandRelationController.java

  @GetMapping("/brands/list")
    public R relationBrandsList(@RequestParam(value = "catId",required = true)Long catId){
        List<BrandEntity> vos = categoryBrandRelationService.getBrandsByCatId(catId);

        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);

    }

返回信息只需品牌id和品牌名所以编写一个只包含品牌id和品牌名的Vo
BrandVo

import lombok.Data;

@Data
public class BrandVo {

    /**
     * "brandId": 0,
     * "brandName": "string",
     */
    private Long brandId;
    private String  brandName;
}

CategoryBrandRelationServiceImpl.java

 /**
     * 查询指定品牌的分类信息
     * @param catId
     * @return
     */
    @Override
    public List<BrandEntity> getBrandsByCatId(Long catId) {
        List<CategoryBrandRelationEntity> catelogId = relationDao.selectList(new QueryWrapper<CategoryBrandRelationEntity>().eq("catelog_id", catId));
        List<BrandEntity> collect = catelogId.stream().map(item -> {
            Long brandId = item.getBrandId();
            BrandEntity byId = brandService.getById(brandId);
            return byId;
        }).collect(Collectors.toList());
        return collect;
    }

P75没完成
P86需要再排查

获取分类下所有分组以及属性

创建 AttrGroupWithAttrsVo.java 整合该类型的结果并返回

@Data
public class AttrGroupWithAttrsVo {
    /**
     * 分组id
     */
    private Long attrGroupId;
    /**
     * 组名
     */
    private String attrGroupName;
    /**
     * 排序
     */
    private Integer sort;
    /**
     * 描述
     */
    private String descript;
    /**
     * 组图标
     */
    private String icon;
    /**
     * 所属分类id
     */
    private Long catelogId;

    private List<AttrEntity> attrs;
}

AttrGroupServiceImpl.java

    /**
     * 根据分类id查出所有分组以及组里的属性
     * @param catelogId
     * @return
     */
    @Override
    public List<AttrGroupWithAttrsVo> getAttrGroupWithAttrsByCatelogId(Long catelogId) {
        //1、查询分组信息
        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 -> {
            AttrGroupWithAttrsVo attrsVo = new AttrGroupWithAttrsVo();
            BeanUtils.copyProperties(group,attrsVo);
            //查询属性
            List<AttrEntity> attrs = attrService.getRelationAttr(attrsVo.getAttrGroupId());
            attrsVo.setAttrs(attrs);
            return attrsVo;
        }).collect(Collectors.toList());

        return collect;
    }

商品新增业务流程分析

保存商品vo
SpuInfoController.java

    @RequestMapping("/save")
    public R save(@RequestBody SpuSaveVo vo){
        spuInfoService.saveSpuInfo(vo);

        return R.ok();
    }

SkuInfoServiceImpl.java
//主要保存商品基本的spu和sku信息

    public void saveSpuInfo(SpuSaveVo vo) {

            AttrEntity attrEntity=attrService.getById(attr.getAttrId());
            valueEntity.setAttrName(attrEntity.getAttrName());
            valueEntity.setAttrValue(attr.getAttrValues());
            valueEntity.setQuickShow(attr.getShowDesc());
            valueEntity.setSpuId(infoEntity.getId());
            return valueEntity;
        }).collect(Collectors.toList());
        productAttrValueService.saveProdutAttr(collect);
        //5.保存spu的积分信息：gulimall_sms->sms_spu_bounds
        //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){

                String defaultImg="";
                for(Images image:item.getImages()){
                    if(image.getDefaultImg()==1){
                        defaultImg=image.getImgUrl();
                    }
                }
                SkuInfoEntity skuInfoEntity=new SkuInfoEntity();
                BeanUtils.copyProperties(item,skuInfoEntity);
                skuInfoEntity.setBrandId(infoEntity.getBrandId());

                skuInfoEntity.setSaleCount(0L);
                skuInfoEntity.setSpuId(infoEntity.getId());
                skuInfoEntity.setSkuDefaultImg(defaultImg);

                }).collect(Collectors.toList());
                //5.2 sku图片信息 pms_sku_images

        }
        //5.4 sku优惠、满减信息：gulimall_sms->sms_sku_ladder\sms_sku_full_reduction\sms_member_price
    }

调用远程服务保存优惠券信息

使用远程服务
可以调用coupon中对应的服务
CouponFeignService.java

@FeignClient("gulicoupon")
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
     * @return
     */
    @PostMapping("/gulicoupon/spubounds/save")
    R saveSpuBounds(@RequestBody SpuBoundTo spuBoundTo);
    @PostMapping("/gulicoupon/skufullreduction/saveinfo")
    R saveSkuReduction(@RequestBody SkuReductionTo skuReductionTo);
}

SPU检索

在这里插入图片描述

SpuInfoController.java

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

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

SpuInfoServiceImpl.java

  @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)){
            wrapper.eq("brand_id",brandId);
        }

        String catelogId = (String) params.get("catelogId");
        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);
    }

SKU检索

SkuInfoController.java

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

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

SkuInfoServiceImpl.java

 @Override
    public PageUtils queryPageByCondition(Map<String, Object> params) {
        QueryWrapper<SkuInfoEntity> queryWrapper = new QueryWrapper<>();
        /**
         * key:
         * catelogId: 0
         * brandId: 0
         * 价格区间
         * 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);
    }
