电商项目9：新增商品
电商项目9：新增商品
- 1、前端
-
- 1.1、修复前端组件通信问题
- 1.2、引入其他前端代码
- 1.3、会员等级列表
- 1.4、当前分类关联的所有品牌
- 2、后端
-
- 2.1、会员系统搭建（注册与发现）
- 2.2、当前分类关联的所有品牌
- 2.3、获取分类下所有分组&关联属性
- 2.4、商品新增
-
- 2.4.1、商品新增vo的封装
- 2.4.2、vo的处理
- 2.4.3、远程调用feign
- 2.4.4 、debug商品新增
1、前端
1.1、修复前端组件通信问题
这是组件通信没有引入依赖
npm i pubsub-js
在main.js中引入
import PubSub from 'pubsub-js'
然后挂载全局就可以使用了
解决了这个问题
1.2、引入其他前端代码
1.3、会员等级列表
前端是写好了。需要后端写完接口
1.4、当前分类关联的所有品牌
后端未编写接口
2、后端
2.1、会员系统搭建（注册与发现）
application.yml
application:
name: gulimall-member
修改数据库连接地址和注册到注册中心的实例名称
网关修改路由地址：
- id: member_route
#负载均衡到member服务
uri: lb://gulimall-member
predicates:
- Path=/api/member/**
#网关重写
filters:
- RewritePath=/api/(?.*),/$\{segment}
启动项目
就可以查询了
会员等级初始化sql语句
INSERT INTO `ums_member_level` VALUES (1, '普通会员', 0, 0, 299.0000, 10, 0, 0, 1, '初级会员');
INSERT INTO `ums_member_level` VALUES (2, '铜牌会员', 3000, 0, 279.0000, 30, 0, 1, 1, '铜牌会员');
INSERT INTO `ums_member_level` VALUES (3, '银牌会员', 5000, 0, 229.0000, 50, 0, 1, 1, '银牌会员');
2.2、当前分类关联的所有品牌
CategoryBrandRelationController
/**
* 获取分类关联的品牌
*/
@GetMapping("/brands/list")
public R getBrandsList(@RequestParam("catId") Long catId){
List brandVoList = categoryBrandRelationService.getBrandsList(catId);
List collect = brandVoList.stream().map(item -> {
BrandEntity brandEntity = new BrandEntity();
brandEntity.setBrandId(item.getBrandId());
brandEntity.setName(item.getBrandName());
return brandEntity;
}).collect(Collectors.toList());
return R.ok().put("data",collect);
}
CategoryBrandRelationService
List getBrandsList(Long catId);
CategoryBrandRelationServiceImpl
@Override
public List getBrandsList(Long catId) {
List catelog = relationDao.selectList(new QueryWrapper().eq("catelog_id", catId));
List collect = catelog.stream().map(item -> {
BrandVo brandVo = new BrandVo();
Long brandId = item.getBrandId();
// 根据brandId查询商品信息
BrandEntity brandEntity = brandDao.selectById(brandId);
if (brandEntity == null) {
brandVo.setBrandId(item.getBrandId());
return brandVo;
}
brandVo.setBrandId(brandId);
brandVo.setBrandName(brandEntity.getName());
return brandVo;
}).collect(Collectors.toList());
return collect;
}
2.3、获取分类下所有分组&关联属性
AttrGroupController
/**
* 获取分类下所有分组&关联属性
*
* @param catelogId catelogId
* @return R
*/
// /product/attrgroup/{catelogId}/withattr
@GetMapping("/{catelogId}/withattr")
public R getAttrGroupAndAttr(@PathVariable Long catelogId){
List attrGroupAndAttrVos = attrGroupService.getAttrGroupAndAttr(catelogId);
return R.ok().put("data",attrGroupAndAttrVos);
}
AttrGroupService
List getAttrGroupAndAttr(Long catelogId);
AttrGroupServiceImpl
@Override
public List getAttrGroupAndAttr(Long catelogId) {
// 1、查出当前分类下的所有属性分组
List groupEntities = this.baseMapper.selectList(new QueryWrapper().eq("catelog_id", catelogId));
// 2、查出每个属性分组的所有属性
List collect = groupEntities.stream().map(item -> {
AttrGroupAndAttrVo attrGroupAndAttrVo = new AttrGroupAndAttrVo();
BeanUtils.copyProperties(item,attrGroupAndAttrVo);
Long attrGroupId = item.getAttrGroupId();
List attrEntities = attrService.getRelationByAttrGroupId(attrGroupId);
attrGroupAndAttrVo.setAttrs(attrEntities);
return attrGroupAndAttrVo;
}).collect(Collectors.toList());
return collect;
}
2.4、商品新增

可以借用一个网址。json生成javaBean
转换javaBean网址
将json粘贴在此，填写基础的类名，包名。点击生成javaBean。然后下载代码，复制到idea
2.4.2、vo的处理
1、所有价格字段不能用double，必须使用BigDecimal。避免精度丢失
2、带Id字段用Long类型
在SpuInfoController来完成代码编写
梳理整个商品新增保存功能操作涉及的数据库
记得加事务
@Transactional
@Override
public void saveSpuInfo(SpuSaveVo spuInfo) {
// 1、保存spu基本信息 pms_spu_info
// 2、保存spu描述图片 pms_spu_info_desc
// 3、保存spu图片集 pms_spu_images
// 4、保存spu规格参数 pms_product_attr_value
// 5、保存spu积分信息 gulimall_sms--> sms_spu_bounds
// 6、保存当前spu的所有sku信息：
// 6.1）、sku基本信息 pms_sku_info
// 6.2）、sku图片信息（默认图片） pms_sku_images
// 6.3）、sku的销售属性信息 pms_sku_sale_attr_value
// 6.4）、sku的优惠、满减信息 gulimall_sms--> sms_sku_ladder\sms_sku_full_reduction\sms_member_price
}
@Transactional
@Override
public void saveSpuInfo(SpuSaveVo spuInfo) {
// 1、保存spu基本信息 pms_spu_info
SpuInfoEntity spuInfoEntity = new SpuInfoEntity();
BeanUtils.copyProperties(spuInfo,spuInfoEntity);
spuInfoEntity.setCreateTime(new Date());
this.saveSpu(spuInfoEntity);
// 2、保存spu描述图片 pms_spu_info_desc
SpuInfoDescEntity spuInfoDescEntity = new SpuInfoDescEntity();
spuInfoDescEntity.setSpuId(spuInfoEntity.getId());
spuInfoDescEntity.setDecript(String.join(",",spuInfo.getDecript()));
spuInfoDescService.save(spuInfoDescEntity);
// 3、保存spu图片集 pms_spu_images
List images = spuInfo.getImages();
imagesService.saveImages(spuInfoEntity.getId(),images);
// 4、保存spu规格参数 pms_product_attr_value
List baseAttrs = spuInfo.getBaseAttrs();
if (baseAttrs != null && baseAttrs.size() > 0){
List collect = baseAttrs.stream().map(attr -> {
ProductAttrValueEntity entity = new ProductAttrValueEntity();
entity.setSpuId(spuInfoEntity.getId());
entity.setAttrId(attr.getAttrId());
// 根据属性id查询属性名
AttrEntity attrEntity = attrService.getBaseMapper().selectById(attr.getAttrId());
if (attrEntity != null){
entity.setAttrName(attrEntity.getAttrName());
}
entity.setAttrValue(attr.getAttrValues());
entity.setQuickShow(attr.getShowDesc());
return entity;
}).collect(Collectors.toList());
attrValueService.saveBatch(collect);
}
// 5、保存spu积分信息 gulimall_sms--> sms_spu_bounds
// 6、保存当前spu的所有sku信息：
List skus = spuInfo.getSkus();
if (skus != null && skus.size() > 0) {
for (Skus sku : skus) {
List image = sku.getImages();
String defaultImage = "";
for (Images img : image) {
if (img.getDefaultImg() == 1) {
// 是否为默认图片为是的
defaultImage = img.getImgUrl();
}
}
SkuInfoEntity skuInfoEntity = new SkuInfoEntity();
BeanUtils.copyProperties(sku, skuInfoEntity);
// 保存其他基本信息
skuInfoEntity.setSkuDefaultImg(defaultImage);
skuInfoEntity.setBrandId(spuInfo.getBrandId());
skuInfoEntity.setCatalogId(spuInfo.getCatalogId());
skuInfoEntity.setSaleCount(0L);
// 6.1）、sku基本信息 pms_sku_info
skuInfoService.insert(skuInfoEntity);
Long skuId = skuInfoEntity.getSkuId();
// 6.2）、sku图片信息（默认图片） pms_sku_images
List skuImagesEntities = image.stream().map(

entity.setSkuId(skuId);
entity.setDefaultImg(img.getDefaultImg());
entity.setImgUrl(img.getImgUrl());
return entity;
}
).collect(Collectors.toList());
skuImagesService.saveBatch(skuImagesEntities);
// 6.3）、sku的销售属性信息 pms_sku_sale_attr_value
List attr = sku.getAttr();

skuSaleAttrValueService.saveBatch(skuSaleAttrValueEntities);
// 6.4）、sku的优惠、满减信息 gulimall_sms--> sms_sku_ladder\sms_sku_full_reduction\sms_member_price
}
}
}
private void saveSpu(SpuInfoEntity spuInfoEntity) {
this.baseMapper.insert(spuInfoEntity);
}
2.4.3、远程调用feign
需要在product工程里调用coupon优惠券工程的接口
1、创建product下的包和接口
2、调用哪个服务
3、启动类加
@EnableFeignClients(“com.ljs.gulimall.product.feign”)
扫描当前feign写的类
4、a服务需要给b服务传递对象。此时这个对象应该封装成TO。双方都在使用
5、SpuInfoServiceImpl
// 5、保存spu积分信息 gulimall_sms--> sms_spu_bounds
Bounds bounds = spuInfo.getBounds();
SpuBoundsTo spuBoundsTo = new SpuBoundsTo();
BeanUtils.copyProperties(bounds,spuBoundsTo);
spuBoundsTo.setSpuId(spuInfoEntity.getId());
couponFeignService.saveSpuBounds(spuBoundsTo);
6、CouponFeignService
@PostMapping("/coupon/spubounds/save")
void saveSpuBounds(@RequestBody SpuBoundsTo spuBoundsTo);
7、SpuBoundsController-优惠服务
8、同理实现sku的优惠、满减信息远程调用保存

2.4.4 、debug商品新增
idea的一键重启
再设置所有模块占用内存100m
在vm里配置
-DXmx100m
我们开启事务以后，断点调试。发现第一步新增已经成功，但是数据库没有数据
因为开启了事务。mysql默认的隔离级别：可重复读。只能读到事务提交的数据
此时方便调试可以在mysql表中执行：
将隔离级别设置为读未提交
set session TRANSACTION ISOLATION LEVEL READ UNCOMMITTED;
这时候通过
show variables like '%isolation%'
###可以看到当前会话已经变为读未提交。此命令是针对当前会话不是全局的。方便调试。关闭会话后，mysql自动回到可重复读
这时候在当前会话查询可以查询到刚才新增成功的一条数据。但事务是未提交的
保存图片时出错，因为id不是自增。我们需要新增时插入id。这里需要修改
保存sku图片时发现url没有
要进行过滤
满0件打0折数据保存也是无意义的
