目录
1.发布商品
2.获取分类关联品牌
3.获取分类下所有分组和关联属性
4.商品保存功能
5.sup检索
6.sku检索
1.发布商品
获取用户系统等级~，前面生成了后端代码，在因为添加了网关，所以要配置陆游规则
在网管层配置会员服务的路由规则，精确的路由放到上面
#会员服务
- id: member_route
uri: lb://gulimall-member
predicates:
- Path=/api/member/**
filters:
- RewritePath=/api/(?.*),/$\{segment} 配置会员服务的配置
1.添加nacos的注册中心地址
2.添加nacos的配置中心地址
3.将配置文件写在bootstrap.yml中
spring:
#数据源
datasource:
driver-class-name: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://192.168.20.129:3306/gulimall_ums
username: root
password: root
cloud:
nacos:
discovery:
# 这里使用了Ngingx
server-addr: 192.168.20.50:1111
config:
server-addr: 192.168.20.50:1111

name: gulimall-member2.获取分类关联品牌
2.1controller
controller处理请求，接收和校验数据，接收service处理完的数据，封装页面指定的vo
@GetMapping("/brands/list")
public R relationBrandList(@RequestParam(value = "catId", required = true) Long catId) {
List vos = categoryBrandRelationService.getBrandByCatId(catId);
List 2.2service
service来接收controller传来的数据，进行业务处理
@Override
public List getBrandsByCatId(Long catId) {
List catelogId = relationDao.selectList(new QueryWrapper().eq("catelog_id", catId));
List collect = catelogId.stream().map(item -> {
Long brandId = item.getBrandId();
BrandEntity byId = brandService.getById(brandId);
return byId;
}).collect(Collectors.toList());
return collect;
} 
3.获取分类下所有分组和关联属性
1.controller
/**
* 获取当前分类下的所有属性分组
*
* @return
*/
@GetMapping("/{catelog_id}/withattr")
public R getAttrGroupWithAttrs(@PathVariable("catelog_id") Long catelog_id) {
//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 vos = attrGroupService.getAttrGroupWithAttrsByCatelogId(catelog_id);
return R.ok().put("data",vos);
}
2.service
如果前端爆foreach异常，但后端数据正常，检查一下属性分组里面，必须保证每一个组名至少关联一个属性名，否则为null，后端需要判断
@Override
public List getAttrGroupWithAttrsByCatelogId(Long catelogId) {
//com.atguigu.gulimall.product.vo
//1、查询分组信息
List attrGroupEntities = this.list(new QueryWrapper().eq("catelog_id", catelogId));
//2、查询所有属性
List collect = attrGroupEntities.stream().map(group -> {
AtttrGroupWithAttrsVo attrsVo = new AtttrGroupWithAttrsVo();
BeanUtils.copyProperties(group, attrsVo);
List attrs = attrService.geRelationAttr(attrsVo.getAttrGroupId());
attrsVo.setAttrs(attrs);
return attrsVo;
}).collect(Collectors.toList());
return collect;
} 
4.商品保存功能
1.controller
@RequestMapping("/save")
//@RequiresPermissions("product:spuinfo:save")
public R save(@RequestBody SpuSaveVo vo){
// spuInfoService.save(spuInfo);
spuInfoService.saveSpuInfo(vo);
return R.ok();
}2.service
service使用feign调用远程服务，注意feign要调用服务的名称，与具体的请求地址
@Transactional
@Override
public void saveSpuInfo(SpuSaveVo vo) {
//1.保存spu基本信息
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
List 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
List images = vo.getImages();
imagesService.saveImages(infoEntity.getId(), images);
//4.保存sup的规格参数
List baseAttrs = vo.getBaseAttrs();
List 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
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sku信息
//5.1、保存sku的基本信息
List 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();
}
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);
skuInfoService.saveSkuInfo(skuInfoEntity);
Long skuId = skuInfoEntity.getSkuId();
List 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
// TODO 没有图片路径的无需保存
skuImagesService.saveBatch(imagesEntities);
List attr = item.getAttr();
List saleAttrValueEntityList = 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
skuSaleAttrValueService.saveBatch(saleAttrValueEntityList);
// 5.4、sku的优惠满减信息
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spu积分优惠失败");
}
}
}
});
}
} 5.sup检索
1.controller
@RequestMapping("/list")
//@RequiresPermissions("product:spuinfo:list")
public R list(@RequestParam Map params){
PageUtils page = spuInfoService.queryPageByCondition(params);
return R.ok().put("page", page);
} 2.service
service用PageUtils封装模糊查询拼接
@Override
public PageUtils queryPageByCondition(Map params) {
QueryWrapper wrapper = new QueryWrapper<>();
String key = (String) params.get("key");
if (!StringUtils.isEmpty(params.get(key))) {
wrapper.and((w) -> {
w.eq("id", key).or().like("spu_name", key);
});
}
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)) {
wrapper.eq("brand_id", brandId);
}
String catelogId = (String) params.get("catelogId");
if (!StringUtils.isEmpty(catelogId)) {
wrapper.eq("catalog_id", catelogId);
}
IPage page = this.page(
new Query().getPage(params),
wrapper
);
return new PageUtils(page);
} 6.sku检索
1.controller
@RequestMapping("/list")
//@RequiresPermissions("product:skuinfo:list")
public R list(@RequestParam Map params){
PageUtils page = skuInfoService.queryPageByCondition(params);
return R.ok().put("page", page);
} 2.service
@Override
public PageUtils queryPageByCondition(Map params) {
QueryWrapper 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);
});
}
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);
}
IPage page = this.page(
new Query().getPage(params),
wrapper
);
return new PageUtils(page);
}
