基於EF Core的Code First模式的DotNetCore快速開發框架

前言

最近接了幾個小單子,由於是小單子,項目規模都比較小,業務相對來講,也比較簡單。因此在選擇架構的時候,考慮到效率方面的因素,就採起了asp.net+entity framework中的code first模式,從而能夠進行快速開發。幾個單子作完下來,順便總結整理一下,近些時候也一直在學習dotnetcore,索性將項目都升級了,因而便有了這一套「基於EF Core的Code First模式的DotNetCore快速開發框架」。至於code first模式的優劣,此文將再也不贅述。至於本文的目的,一是爲了總結和整理工做這幾年所學的一些知識,方便之後可以快速高效地接入項目中。再是分享出來,跟你們一塊兒探討學習,一塊兒進步。歡迎各路大佬指正和建議^_^git

項目架構

此項目主要分紅兩部分:Zxw.Framework.NetCore (核心類庫)和 NetCore.Sample (示例)兩部分。如圖所示:框架

Zxw.Framework.NetCore 項目說明:asp.net

  • Attributes —— 一些經常使用的屬性
  • CodeGenerator —— 代碼生成器,用於生成Repository和Service層的代碼
  • CodeTemplate —— Repository和Service層代碼模板
  • EfDbContext —— EF上下文
  • Extensions —— 一些經常使用的擴展方法
  • Filters —— 一些經常使用的攔截器
  • Helpers —— 一些經常使用的幫助類
  • IoC —— IoC容器封裝類,Autofac
  • IRepositories —— Repository接口類
  • IServices —— Service接口類
  • Middlewares —— 中間件
  • Models —— 實體接口類,IBaseModel<TKey>
  • Options —— 一些經常使用的配置類
  • Repositories —— Repository層的父類
  • Services —— Service層的父類

框架使用

NetCore.Sample 所示,按照此項目結構建立好:ide

  • Zxw.Framework.Website —— 網站
  • Zxw.Framework.Website.Controllers —— 控制器
  • Zxw.Framework.Website.IRepositories —— 倉儲接口
  • Zxw.Framework.Website.IServices —— Service接口
  • Zxw.Framework.Website.Models —— 實體
  • Zxw.Framework.Website.Repositories —— 倉儲
  • Zxw.Framework.Website.Services —— Services
  • Zxw.Framework.Website.ViewModels —— ViewModels

安裝nuget package:

Install-Package Zxw.Framework.NetCore -Version 1.0.1

須要注意如下幾點:

  1. 全部實體都需實現IBaseModel<TKey>接口(TKey是主鍵類型),若是須要在數據庫中生成對應的數據表
  2. 若是IRepositories、IServices、Repositories、Services這四個項目沒有單獨創建,調用代碼生成器生成的代碼將存在於調用項目的目錄下
  3. 利用代碼生成器生成的代碼文件須要手動添加到項目中

實體示例:

 1 using System.ComponentModel.DataAnnotations;
 2 using System.ComponentModel.DataAnnotations.Schema;
 3 using Zxw.Framework.NetCore.Models;
 4 
 5 namespace Zxw.Framework.Website.Models
 6 {
 7     public class TutorClassType:IBaseModel<int>
 8     {
 9         [Key]
10         [Column("TutorClassTypeId")]
11         public int Id { get; set; }
12 
13         [Required]
14         [StringLength(maximumLength:50)]
15         public string TutorClassTypeName { get; set; }
16         public bool Active { get; set; } = true;
17         [StringLength(maximumLength:200)]
18         public string Remark { get; set; }
19         public int TutorClassCount { get; set; }
20     }
21 }

寫博客真的很費力,但願本身可以堅持下去。
