summary
I have already explained the background of this framework. If you are not clear, you can view this link
1,The minimalist and practical Asp.NetCore modular framework has decided to open source for free
2,The minimalist and practical Asp.NetCore modular framework adds CMS module
After all, I haven't updated my blog for a long time. During this period, I have been on business. In my spare time, I have been thinking that the dotnetcore framework itself is modular. Why do I continue to carry out modular packaging on this upper application? What's the significance? Is it for better business division or wheel reuse?
On reflection, this framework should not continue to be modularized, mainly for the following reasons:
1. In terms of my existing business, there is no need for modularization. I just make a large and global system (authority management, content management, mall, wechat management, etc.).
2. If you want to be modular, you have to sacrifice some performance. This is unacceptable after I think over and over again. The main reason is that you sacrifice a little more performance!
3. Dotnetcore itself is more friendly and modular. There is no need to wrap another layer on this upper application, which makes no sense. After downloading the dotnetcore source code, I think its design concept is very good, so "dotnetcore" itself is the best modular (Modular) framework, which can devote a lot of time and energy to the research of the source code, There is no need to tangle with the concept of modularity. It is very little for the growth of technology to toss around in the upper layer.
4. In the past, it was divided into modules to develop towards micro services. At that time, try to make small changes. Now think about it. I'm just a background manager. There's no need to think so much.
Based on the above points, I changed the framework and reserved the branches of the original modular framework (not all modular in a sense).
New business functions
A new mall module is added, which mainly includes commodity management (supporting multiple SKUs), commodity classification, applet users, user harvest address and list of order status.
Some back-end codes for adding and modifying items:
public async Task<ApiResult> AddAsync(GoodsInput input) { try { Db.BeginTran(); // Save goods var goods = _mapper.Map<Goods>(input); var goodsId = await Db.Insertable<Goods>(goods).ExecuteReturnIdentityAsync(); // Save specification await DealwithGoodsSpec(goodsId, input); Db.CommitTran(); } catch (Exception e) { Db.RollbackTran(); return new ApiResult(e.Message); } return new ApiResult(); } /// <summary> /// Public commodity specification information processing /// </summary> /// <param name="goodsId"></param> /// <param name="input"></param> /// <returns></returns> private async Task DealwithGoodsSpec(int goodsId, GoodsInput input) { // Save specification if (input.SpecType == SpecTypeEnum.Single.GetValue<int>()) { var specSingle = JsonConvert.DeserializeObject<GoodsSpecInput>(input.SpecSingle); input.GoodsSpecInput = specSingle; var goodsSpec = input.BuildGoodsSpec(goodsId); if (null == goodsSpec) { throw new FriendlyException("Commodity specification entity data cannot be empty!"); } await Db.Insertable(goodsSpec).ExecuteReturnIdentityAsync(); } else { var goodsSpecs = input.BuildGoodsSpecs(goodsId); if (null == goodsSpecs || goodsSpecs.Count == 0) { throw new FriendlyException("Commodity specification entity data set cannot be empty!"); } await Db.Insertable(goodsSpecs).ExecuteReturnIdentityAsync(); var goodsSpecRels = input.BuildGoodsSpecRels(goodsId); if (goodsSpecRels.Count == 0 || goodsSpecRels == null) { throw new FriendlyException("Commodity specification entity relationship set data cannot be empty!"); } //Reverses the specification group based on the specification value id var specValues = await Db.Queryable<SpecValue>().Where(d => d.Status).ToListAsync(); foreach (var item in goodsSpecRels) { var specId = specValues.Where(d => d.Status && d.Id == item.SpecValueId).Select(d => d.SpecId); item.SpecId = specId.FirstOrDefault(); } await Db.Insertable(goodsSpecRels).ExecuteReturnIdentityAsync(); } } public async Task<ApiResult> ModifyAsync(GoodsModifyInput input) { var goods = await GetModelAsync(d => d.Id == input.Id); if (goods == null) throw new FriendlyException($"This product{input.Id}No corresponding product information was found"); try { Db.BeginTran(); // Update product var model = _mapper.Map<Goods>(input); var goodsId = await Db.Updateable(model).IgnoreColumns(d => new { d.CreateTime }).ExecuteCommandAsync(); // Update specifications await Db.Deleteable<GoodsSpec>().Where(d => d.GoodsId == input.Id).ExecuteCommandAsync(); await Db.Deleteable<GoodsSpecRel>().Where(d => d.GoodsId == input.Id).ExecuteCommandAsync(); // Save specification await DealwithGoodsSpec(input.Id, input); Db.CommitTran(); } catch (Exception e) { Db.RollbackTran(); return new ApiResult(e.Message); } return new ApiResult(); }

Only part of the code is posted here. You can directly see the source code for more details. In addition, it's not too much to write a series about the design of the mall. Next time, I'll take the time to write an article to introduce the multi specifications of goods and how to design better.
