.Net Core3.1 MVC + EF Core+ AutoFac+LayUI+Sqlserver的框架搭建--------基礎架構
阿新 • • 發佈:2021-11-02
從18年畢業到現在幹開發轉眼都三四年了,當然17年沒畢業我就幹了差不多一年了,不過做的不是.net 開發,而是Unity3D遊戲開發。這幾年來一邊開發一邊自學,一直忙忙碌碌,是該靜下心來好好總結一下了。
我從開始.net 開發到現在,由最開始的MVC4,MVC5,到.net core2.1,.net core2.2 ,到現在我打算用.net core3.1對以前學的東西做個總結。
架構還是典型的三層架構,只不過為了低耦合層與層之間依賴介面而已。首先介紹整體結構:
接下來我們就要一點一點的把架構搭建起來了:
在appsettings.json配置資料庫連線物件,這裡用sqlserver2019資料庫,注意:.net core3.1以後選用sqlserver資料庫一定要用sqlserver2012以上的版本,不然能連線,但是EF模型對映的時候取資料會異
{ "ConnectionStrings": { "SmartNetConnStr": "Server=LAPTOP-FOJA6HBQ\\SQLEXPRESS;uid=sa;pwd=123;Database=CoreNet;MultipleActiveResultSets=true;" },
//rides後面會說 "RedisCaching": { "Enabled": true, "RedisConnectionString": "127.0.0.1:6379" }, "Logging": { "LogLevel": {"Default": "Warning" } }, "AllowedHosts": "*" }
接下來就是資料庫的上下文:
using Core.Net.Model; using Core.Net.Model.System; using Microsoft.EntityFrameworkCore; namespace Core.Net.Common.Core.Net.Data { public class CoreNetDBContext : DbContext { /// <summary> /// 設定EF資料庫連結字串 /// </summary> public static string DbConnStr { get; set; } protected override void OnModelCreating(ModelBuilder modelBuilder) { base.OnModelCreating(modelBuilder); } /// <summary> /// DbContext 初始化時呼叫 /// </summary> /// <param name="optionsBuilder"></param> [System.Obsolete] protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder) { //optionsBuilder.UseSqlServer(@"Server=(localdb)\mssqllocaldb;database=NotifyBird;Trusted_Connection=True;"); //配置資料鏈接 optionsBuilder.UseSqlServer(DbConnStr); } }
然後在startup中註冊:
//1、EF設定字串初始化模式 CoreNetDBContext.DbConnStr = Configuration.GetConnectionString("SmartNetConnStr");
到這裡資料庫配置就完成了。
接下來我們定義每一層的基類:
IBaseRepository:
using Core.Net.Common.Core.Net.Core; using System; using System.Collections.Generic; using System.Linq; using System.Linq.Expressions; using System.Text; using System.Threading.Tasks; namespace Core.Net.IRepository { public interface IBaseRepository<T> where T : class, new() { int Insert(T entity); int Insert(List<T> entitys); int Update(T entity); int Delete(string propertyName, object propertyValue); int DeleteList(string propertyName, object propertyValue); int Delete(T entity); T FindEntity(string propertyName, object propertyValue); IQueryable<T> IQueryable(); List<T> FindList(PageModel page, string propertyName, bool orderbyDesc); List<T> FindList(string propertyName, bool orderbyDesc); List<T> FindList(string propertyName, object propertyValue); IQueryable<T> IQueryable(string propertyName, object propertyValue, string orderByName, bool orderbyDesc); T GetEntityOne(Expression<Func<T, bool>> where); IQueryable<T> GetEntityList(Expression<Func<T, bool>> where); IQueryable<T> IQueryableDouble(string propertyName, object propertyValue, string propertyNames, object propertyValues, string orderByName, bool orderbyDesc); IQueryable<T> IQueryableDouble(string propertyName, object propertyValue, string propertyName1, object propertyValue1, string propertyName2, object propertyValue2, string orderByName, bool orderbyDesc); List<T> FindList(PageModel page, string propertyName, object propertyValue, string orderByName, bool orderbyDesc); List<T> FindList(PageModel page, Expression<Func<T, bool>> whereLambda, Expression<Func<T, int>> orderbyLambda, bool orderbyDesc); List<T> FindList(string propertyName, object propertyValue, string orderByName, bool orderbyDesc); List<T> FindList(PageModel page, Expression<Func<T, bool>> whereLambda, Expression<Func<T, object>> orderbyLambda, bool orderbyDesc, Expression<Func<T, object>> thenbyLambda, bool thenbyDesc); List<T> GetTEntityList(Expression<Func<T, bool>> where); IQueryable<T> GetEntityListOrder<orderkey>(Expression<Func<T, bool>> where, Expression<Func<T, orderkey>> orderbykey, bool asc = true); List<T> GetTEntityListOrder<orderkey>(Expression<Func<T, bool>> where, Expression<Func<T, orderkey>> orderbykey, bool asc = true); IQueryable<T> GetEntityPaginationListOrder<orderkey>(int pageSize, int pageIndex, Expression<Func<T, orderkey>> orderbykey, out int rowscount, bool asc = true); List<T> GetTEntityPaginationListOrder<orderkey>(int pageSize, int pageIndex, Expression<Func<T, orderkey>> orderbykey, out int rowscount, bool asc = true); IQueryable<T> GetEntityPaginationListOrder<orderkey>(int pageSize, int pageIndex, Expression<Func<T, bool>> where, Expression<Func<T, orderkey>> orderbykey, out int rowscount, bool asc = true); List<T> GetTEntityPaginationListOrder<orderkey>(int pageSize, int pageIndex, Expression<Func<T, bool>> where, Expression<Func<T, orderkey>> orderbykey, out int rowscount, bool asc = true); int SaveChanges(); } }

ICoreNetSystemUserServices:
using Core.Net.Model.System; using System; using System.Collections.Generic; using System.Text; namespace Core.Net.IServices { public interface ICoreNetSystemUserServices : IBaseServices<CoreNetSystemUser> { } }
CoreNetSystemUserServices:
using Core.Net.IRepository; using Core.Net.IServices; using Core.Net.Model.System; namespace Core.Net.Services { public class CoreNetSystemUserServices : BaseServices<CoreNetSystemUser>, ICoreNetSystemUserServices { public CoreNetSystemUserServices(ICoreNetSystemUserRespository dal) { base.dal = dal; } } }
到這裡一個簡單的架構已經成型了,至於怎末使用後續在加入Layui前端框架的時候會詳細說明。
