二、创建项目

层级介绍：
Web层 UI 层
Services 业务逻辑接口层
Repository 业务数据处理层
Models 实体映射层
TestServices 业务逻辑单元测试层

设置引用关系：
Web层调用 Models、Services 层
Services层调用 Repository、Models 层
Repository层调用 Models 层
Models层实体层

TestServices 业务逻辑单元测试层调用 Models、Services 层

①Models层创建
EF CORE 映射实体：
安装 NuGet 包
Microsoft.EntityFrameworkCore.SqlServer
Microsoft.EntityFrameworkCore.Design
Microsoft.EntityFrameworkCore.Tools

映射实体

PM> Scaffold-DbContext -Force “Server=.;database=Test_Demo;Trusted_Connection=True;” Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models

映射的表和 Context

修改Context OnConfiguring方法

public static string ConnectionString { get; set; }
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{if (!optionsBuilder.IsConfigured){#warning To protect potentially sensitive information in your connection string, you should move it out of source code. You can avoid scaffolding the connection string by using the Name= syntax to read it from configuration - see https://go.microsoft.com/fwlink/?linkid=2131148. For more guidance on storing connection strings, see http://go.microsoft.com/fwlink/?LinkId=723263.//optionsBuilder.UseSqlServer("Server=.;database=Test_Demo;Trusted_Connection=True;");optionsBuilder.UseSqlServer(ConnectionString);}
}

②Repository 层创建（引用Models层）

    public class TheTreeRepository : Test_DemoContext{Test_DemoContext Contexts = new Test_DemoContext();//Contexts.WDPackingListLevels.Where(x => true).ToList();SQLHelper sqlhelper = new SQLHelper(Test_DemoContext.ConnectionString);public IList<SySDepartment> WDPackingListLevelsRepository(){return SySDepartments.Where(x => true).ToList();/** *  var model = db.WDPackingListLevels.Where(x => true).ToList();//获取sql查询//1.创建接收实体：ModelName.cs//2.添加到数据库上下文：public virtual DbSte<ModelName> modelname {get; set;}//3.获取//var sql = "SELECT * FROM dbo.W_D_PACKING_LIST_LEVEL";//var model = db.Set<WDPackingListLevel>().FromSqlRaw(sql).ToList();*//*using (var db = new iROCK_DEVContext()){var model = db.WDPackingListLevels.Where(x => true).ToList();//获取sql查询//1.创建接收实体：ModelName.cs//2.添加到数据库上下文：public virtual DbSte<ModelName> modelname {get; set;}//3.获取//var sql = "SELECT * FROM dbo.W_D_PACKING_LIST_LEVEL";//var model = db.Set<WDPackingListLevel>().FromSqlRaw(sql).ToList();return View(model);}*/}public DataTable WDPackingListLevelsRepositoryDT(){var sql = "SELECT * FROM dbo.W_D_PACKING_LIST_LEVEL";var model = Set<SySDepartment>().FromSqlRaw(sql);return (DataTable)model;}public IList<SySDepartment> WDPackingListLevelsRepository3(){var sql = "SELECT * FROM dbo.W_D_PACKING_LIST_LEVEL";var dt = SQLHelper.GetTable(sql);var model = Set<SySDepartment>().FromSqlRaw(sql).ToList();return model;}public DataTable GetTreeDataRepository(){//树形菜单绑定string str = $@"IF NOT OBJECT_ID(N'Tempdb..#T2') IS NULLDROP TABLE #T2;SELECT  R.id, DE.DEPT_CODE ,VA.MEANING AS name ,DE.UPPER_DEPT,R1.parentId,LINE_ID,ISNULL(DE.MODIFY_DATE,ISNULL(VA.MODIFY_DATE,ISNULL(R.MODIFY_DATE,ISNULL(R1.MODIFY_DATE,DE.CREATE_DATE)))) AS UP_DATEINTO #T2FROM    SY_S_DEPARTMENT DEINNER JOIN SY_S_GLOBAL_MULTIPLE_LANGUAGE_VALUE VA ON DE.DEPT_CODE = VA.LOOKUP_VALUEINNER JOIN ( SELECT ROW_NUMBER() OVER ( ORDER BY CREATE_DATE,DEPT_CODE ASC ) AS id ,DEPT_CODE,MODIFY_DATEFROM   SY_S_DEPARTMENT) AS R ON R.DEPT_CODE = DE.DEPT_CODE LEFT JOIN ( SELECT ROW_NUMBER() OVER ( ORDER BY CREATE_DATE,DEPT_CODE ASC ) AS ParentId ,DEPT_CODE,MODIFY_DATEFROM   SY_S_DEPARTMENT) AS R1 ON R1.DEPT_CODE = DE.UPPER_DEPTWHERE   VA.LANGUAGE ='zh-cn' --'zh-cn'AND DE.FACILITY='APAT'AND DE.SITE='SZ'; WITH    menu ( id, name, DEPT_CODE, UPPER_DEPT, parentId,LINE_ID,UP_DATE, Level, px, px2 )AS ( SELECT   id ,name ,DEPT_CODE ,UPPER_DEPT ,parentId ,LINE_ID,UP_DATE,0 AS Level ,id px ,CAST(id AS NVARCHAR(4000)) px2FROM     #T2WHERE    parentId IS NULLUNION ALLSELECT   A.id ,A.name ,A.DEPT_CODE ,A.UPPER_DEPT ,A.parentId ,A.LINE_ID,A.UP_DATE,B.Level + 1 ,B.px ,B.px2 + LTRIM(A.id)FROM     #T2 AINNER JOIN menu B ON A.parentId = B.id)SELECT  id ,name ,DEPT_CODE ,UPPER_DEPT ,CASE WHEN parentId IS NULL AND DEPT_CODE='DO' AND id=1 THEN 0WHEN parentId IS NULL AND DEPT_CODE <>'DO'AND id<>1 THEN 1ELSE parentIdEND AS parentId ,LINE_ID,Level ,px ,px2FROM    menuORDER BY LINE_ID ASC,UP_DATE DESC;";return SQLHelper.GetTable(str);}}

③Services 层创建 (引用 Models、Repository 层)

Interface接口层

public interface ITheTreeServices
{//DataTable IndexFilter(string whitelistdto, string param);DataTable GetCodeDescByCodeNamet();IList<SySDepartment> WDPackingListLevelsRepository1();DataTable GetTreeData();
}

Implementation接口调用层

public class TheTreeServices : TheTreeRepository, ITheTreeServices
{public TheTreeServices() { }public DataTable GetCodeDescByCodeNamet(){DataTable data = WDPackingListLevelsRepositoryDT();return data;}public IList<SySDepartment> WDPackingListLevelsRepository1(){return WDPackingListLevelsRepository3();}public DataTable GetTreeData(){return GetTreeDataRepository();}
}

④Web层 Controllers 调用 Implementation 方法

using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Logging;
using Models.Models;
using Services.Implementation;
using System.Diagnostics;
using System.Linq;
using TREE.Models;namespace TREE.Controllers
{public class HomeController : Controller{TheTreeServices _thetreeservices = new TheTreeServices();private readonly ILogger<HomeController> _logger;public HomeController(ILogger<HomeController> logger){_logger = logger;}public IActionResult Index(){//var model="";var dt = _thetreeservices.GetTreeData();var model = _thetreeservices.WDPackingListLevelsRepository();return View(model);}}
}

配置文件：
appsettings.json

{"ConnectionString": {"SqlServerConnectionString": "Server=.;database=Test_Demo;Trusted_Connection=True;" //"Server=192.168.0.0000;Database=datename;User ID=iROCK;Password=12###;"},"Logging": {"LogLevel": {"Default": "Information","Microsoft": "Warning","Microsoft.Hosting.Lifetime": "Information"}},"AllowedHosts": "*"
}

Startup.cs

// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{Test_DemoContext.ConnectionString = Configuration["ConnectionString:SqlServerConnectionString"];services.AddControllersWithViews();
}
