中台框架模块开发实践-用 Admin.Core 代码生成器生成通用代码生成器的模块代码

来源：网络作者：趣玩小编发布时间：2024-07-01 09:46:48

前言

之前分享中台 Admin.Core 的模块代码生成器，陆续也结合群友们的反馈，完善了一些功能和模板上的优化，而本篇将基于此代码生成器生成一个通用代码生成器模块的基本代码

后续再在此代码的基础上进行完善，制作一个通用的代码生成器

要做一个项目，首先我们要弄清楚需求，这里简单规划了下所需要的功能模块

可从脑图中看到，基本除了项目生成这块需要添加代码，相关模块的增删改查都可以由代码生成器来生成

准备

本文开发完成的项目将放在： yimogit/Emo.Dev

本篇开发代码在我 Fork 的仓库 yimogit/Admin.Core

本文主要的阅读者：开发完成后的代码生成器的使用者，使用/将要用 Admin.Core 框架的猿们，如果觉得有用，欢迎点赞留言

实现

项目代码准备

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

在运行项目后连接到数据库执行 sql 创建

--添加视图
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,'代码管理',NULL,NULL,0,99,1,161223411986501,'admin','管理员','2024-06-16 16:08:08',161223411986501,'admin','管理员','2024-06-16 16:08:16',0),
         (558531082424325,558530915442693,'codegen','代码生成','dev/codegen/index',NULL,0,1,1,161223411986501,'admin','管理员','2024-06-16 16:08:49',NULL,NULL,NULL,NULL,0);
-- 添加权限
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,'代码生成',NULL,2,558531082424325,'devgen','/codegen',NULL,'ele-Memo',0,0,0,0,0,0,NULL,0,5,NULL,1,161223411986501,'admin','管理员','2024-06-16 16:10:09',161223411986501,'admin','管理员','2024-06-16 16:10:55',0);

或根据前文中台框架模块开发实践-代码生成器的添加及使用在前台添加代码生成器菜单

生成器的生成方式说明

代码生成器支持DBFirst和CodeFirst两种方式

DBFirst 需要选择数据源并选择数据表进行生成配置的保存

CodeFirst 可以直接生成配置，配置保存后再使用生成迁移SQL或者将迁移执行到数据库的方式同步数据库表信息

这里为了更方便的生成，做了一个 json 的导入导出，可以快速复制/导入分享的配置，下面会贴出配置，直接导入即可,导入时会将id重置，都为新增

建立数据模型并生成代码

通过前面理的需求，可以创建相关模型

模板分组
- 模板信息实体
- DevGroup
模板列表
- 模板信息实体
- DevTemplate
项目生成
- 以项目，项目模型，模型字段组成
- DevProject
- DevProjectModel
- DevProjectModelField

对应代码生成器数据如下，提供这几个模型的基础增删改查功能

对应 json 配置，导入即可

生成模型一览

模板的模型配置参考

生成的后端代码（E:\CodeGenOutput\ZhonTai.Module.Dev）

前端代码（ E:\CodeGenOutput\views）

在 Admin.Core 中使用生成的代码

如果已经有项目可以直接添加对库的引用，这里直接新建一个项目 Emo.Dev

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

可以看到这里只生成了后端接口，目前 v8.2.0 还不支持前端代码的生成，所以我们还需要手动去将对应版本的前端代码下载一份到项目中(只保留)，并调整下目录结构,前端代码放到 admin-ui ,后端代码放到 admin-api

运行前后端项目，确认项目运行没问题后开始添加通用代码生成器模块代码。后续任意模块代码都可以参考步骤

1.后端项目引用关系配置

将生成的模块代码 ZhonTai.Module.Dev 拷贝到在新项目中

修改库中的引用，默认生成的 ZhonTai.Module.Dev.csproj 引用是相对源码的路径

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 项目添加对 ZhonTai.Module.Dev 的引用

签名文件未找到报错处理

添加完成后如果提示前面文件找不到，可将Api下的签名文件复制过来或自行生成

我这里是将Emo.Dev.Api的key.snk文件复制到了platform文件夹，并改了02.build/Directory.Build.props 中程序集签名的文件路径到 ..\kye.snk ，这样就可以让项目中的所有程序集就用这个前面文件

整体修改情况

2.后端配置修改

修改应用配置： ConfigCenter/appconfig.json

修改程序集名称和swagger配置

//程序集名称
"assemblyNames": [ "Emo.Dev.Api", "ZhonTai.Admin", "ZhonTai.Module.Dev" ],
//Swagger接口文档
"swagger": [
    ...
    {
      "name": "代码生成",
      "code": "dev",
      "version": "v8.2.0",
      "description": "代码生成"
    }
    ...
]
