中台框架模塊開發實踐-用 Admin.Core 代碼生成器生成通用代碼生成器的模塊代碼

前言

之前分享中台 Admin.Core 的模塊代碼生成器，陸續也結合群友們的反饋，完善了一些功能和模板上的優化，而本篇將基於此代碼生成器生成一個通用代碼生成器模塊的基本代碼

後續再在此代碼的基礎上進行完善，製作一個通用的代碼生成器

要做一個項目，首先我們要弄清楚需求，這裡簡單規划了下所需要的功能模塊

可從腦圖中看到，基本除了項目生成這塊需要添加代碼，相關模塊的增刪改查都可以由代碼生成器來生成

準備

本文開發完成的項目將放在：yimogit/Emo.Dev

本篇開發代碼在我 Fork 的倉庫 yimogit/Admin.Core

本文主要的閱讀者：開發完成後的代碼生成器的使用者，使用/將要用 Admin.Core 框架的猿們，如果覺得有用，歡迎點贊留言

項目代碼準備

git clone https://github.com/yimogit/Admin.Core.git

在運行項目後連接到資料庫執行 sql 創建

--添加視圖
INSERT INTO ad_view (Id,ParentId,Name,Label,"Path",Description,Cache,Sort,Enabled,CreatedUserId,CreatedUserName,CreatedUserRealName,CreatedTime,ModifiedUserId,ModifiedUserName,ModifiedUserRealName,ModifiedTime,IsDeleted) VALUES
         (558530915442693,0,NULL,'代碼管理',NULL,NULL,0,99,1,161223411986501,'admin','管理員','2024-06-16 16:08:08',161223411986501,'admin','管理員','2024-06-16 16:08:16',0),
         (558531082424325,558530915442693,'codegen','代碼生成','dev/codegen/index',NULL,0,1,1,161223411986501,'admin','管理員','2024-06-16 16:08:49',NULL,NULL,NULL,NULL,0);
-- 添加許可權
INSERT INTO ad_permission (Id,ParentId,Label,Code,"Type",ViewId,Name,"Path",Redirect,Icon,Hidden,Opened,NewWindow,"External",IsKeepAlive,IsAffix,Link,IsIframe,Sort,Description,Enabled,CreatedUserId,CreatedUserName,CreatedUserRealName,CreatedTime,ModifiedUserId,ModifiedUserName,ModifiedUserRealName,ModifiedTime,IsDeleted) VALUES
         (558531409440773,0,'代碼生成',NULL,2,558531082424325,'devgen','/codegen',NULL,'ele-Memo',0,0,0,0,0,0,NULL,0,5,NULL,1,161223411986501,'admin','管理員','2024-06-16 16:10:09',161223411986501,'admin','管理員','2024-06-16 16:10:55',0);

或根據前文中台框架模塊開發實踐-代碼生成器的添加及使用在前臺添加代碼生成器菜單

生成器的生成方式說明

代碼生成器支持DBFirst和CodeFirst兩種方式

DBFirst 需要選擇數據源並選擇數據表進行生成配置的保存

CodeFirst 可以直接生成配置，配置保存後再使用生成遷移SQL或者將遷移執行到資料庫的方式同步資料庫表信息

這裡為了更方便的生成，做了一個 json 的導入導出，可以快速複製/導入分享的配置，下麵會貼出配置，直接導入即可,導入時會將id重置，都為新增

建立數據模型並生成代碼

通過前面理的需求，可以創建相關模型

模板分組
- 模板信息實體
- DevGroup
模板列表
- 模板信息實體
- DevTemplate
項目生成
- 以項目，項目模型，模型欄位組成
- DevProject
- DevProjectModel
- DevProjectModelField

對應代碼生成器數據如下，提供這幾個模型的基礎增刪改查功能

對應 json 配置，導入即可

生成模型一覽

模板的模型配置參考

生成的後端代碼（E:\CodeGenOutput\ZhonTai.Module.Dev）

前端代碼（ E:\CodeGenOutput\views）

在 Admin.Core 中使用生成的代碼

如果已經有項目可以直接添加對庫的引用，這裡直接新建一個項目 Emo.Dev

dotnet new install ZhonTai.Template::8.2.0
dotnet new MyApp -n Emo.Dev

可以看到這裡只生成了後端介面，目前 v8.2.0 還不支持前端代碼的生成，所以我們還需要手動去將對應版本的前端代碼下載一份到項目中(只保留)，並調整下目錄結構,前端代碼放到 admin-ui ,後端代碼放到 admin-api

運行前後端項目，確認項目運行沒問題後開始添加通用代碼生成器模塊代碼。後續任意模塊代碼都可以參考步驟

1.後端項目引用關係配置

將生成的模塊代碼 ZhonTai.Module.Dev 拷貝到在新項目中

修改庫中的引用，預設生成的 ZhonTai.Module.Dev.csproj 引用是相對源碼的路徑

所以需要修改下,直接引用 ZhonTai.Admin 的包

  <ItemGroup>
    <PackageReference Include="ZhonTai.Admin" Version="$(PackageZhonTaiVersion)">
      <CopyToOutputDirectory>***.xml</CopyToOutputDirectory>
    </PackageReference>
  </ItemGroup>

Host 項目添加對 ZhonTai.Module.Dev 的引用

簽名文件未找到報錯處理

添加完成後如果提示前面文件找不到，可將Api下的簽名文件複製過來或自行生成

我這裡是將Emo.Dev.Api的key.snk文件複製到了platform文件夾，並改了02.build/Directory.Build.props 中程式集簽名的文件路徑到 ..\kye.snk ，這樣就可以讓項目中的所有程式集就用這個前面文件

整體修改情況

2.後端配置修改

修改應用配置： ConfigCenter/appconfig.json

修改程式集名稱和swagger配置

//程式集名稱
"assemblyNames": [ "Emo.Dev.Api", "ZhonTai.Admin", "ZhonTai.Module.Dev" ],
//Swagger介面文檔
"swagger": [
