.Net框架搭建之2、SQL Server MEF依賴注入 MVC Repository框架
阿新 • • 發佈：2019-01-14
MEF依賴注入簡介
依賴注入對於開發人員來說，方便的就是不需要去關注具體的實現類，不需要去New例項物件，直接使用介面層就能讓程式自動注入使用，當然，還有其他一些特點，比如web http同一個請求中可以設定同一個物件只例項化一次解決多個類中多次例項化物件浪費資源的問題。不多說，百度能得到更多 多的介紹，這邊直接開工搭環境。
1、資料模型Model層建立
資料模型層，首先要建立資料庫，再建立Model類。
建立資料庫，表，新增一條測試資料
建立資料庫
建立資料表
新增測試資料
我們已經知道有幾層，所以，先把所有的類庫專案全部先建立好，web為MVC的空專案，至於各層程式碼，分到各層再去處理
專案結構
各層依賴關係
好了，一般情況下，在這個框架裡，我們只需要建立相應的Model類與資料庫表相對應就行了，比如這個專案，我們只建立兩個類：
SysUser.cs
/* ==============================================================================
* 功能描述：SysUserInfo
* 創 建 者：蒲奎民
* 建立日期：2016-08-29 15:58:13
* CLR Version :4.0.30319.42000
* ==============================================================================*/ SysUserInfo.cs
/* ==============================================================================
* 功能描述：SysUserInfo
* 創 建 者：蒲奎民
* 建立日期：2016-08-29 15:58:13
* CLR Version :4.0.30319.42000
* ==============================================================================*/
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace InjectExample.Model
{
public partial class SysUserInfo
{
public long ID { get; set; }
public long SysUserId { get; set; }
public int LoginCount { get; set; }
public DateTime LastLoginTime { get; set; }
}
}至此，Model類就建立完成。
2、底層公共方法層Component處理
這層可以說是在這個框架搭建中最複雜的，但是，建立完之後，不需要怎麼改動的地方。
好，為了能滿足框架程式碼需要引用的Nuget包，我這裡列出一下。
2.1 新增Nuget包和 .Net程式集引用
<package id="EntityFramework" version="6.1.3" targetFramework="net45" />
<package id="EntityFramework.Extended" version="6.1.0.168" targetFramework="net45" />
<package id="Microsoft.AspNet.Mvc" version="5.2.3" targetFramework="net45" />
<package id="Microsoft.AspNet.Razor" version="3.2.3" targetFramework="net45" />
<package id="Microsoft.AspNet.WebApi.Client" version="5.2.3" targetFramework="net45" />
<package id="Microsoft.AspNet.WebApi.Core" version="5.2.3" targetFramework="net45" />
<package id="Microsoft.AspNet.WebApi.WebHost" version="5.2.3" targetFramework="net45" />
<package id="Microsoft.AspNet.WebPages" version="3.2.3" targetFramework="net45" />
<package id="Microsoft.Composition" version="1.0.30" targetFramework="net45" />
<package id="Microsoft.Web.Infrastructure" version="1.0.0.0" targetFramework="net45" />
<package id="Newtonsoft.Json" version="6.0.4" targetFramework="net45" /> 在nuget管理器中新增完成就行。
所有專案都勾上，免得麻煩。
還有一些，要新增系統的程式集，比如 System.Web，System.Configuration等等。
2.2 建立mvc依賴注入相關類：
先新增一個擴充套件類ConfigurationExt.cs，用來載入bin目錄下的所有程式集
