.Net Core3.1 MVC + EF Core+ AutoFac+LayUI+Sqlserver的框架搭建--------基础架构
本文主要是介绍.Net Core3.1 MVC + EF Core+ AutoFac+LayUI+Sqlserver的框架搭建--------基础架构，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
从18年毕业到现在干开发转眼都三四年了，当然17年没毕业我就干了差不多一年了，不过做的不是.net 开发，而是Unity3D游戏开发。这几年来一边开发一边自学，一直忙忙碌碌，是该静下心来好好总结一下了。
我从开始.net 开发到现在，由最开始的MVC4，MVC5，到.net core2.1,.net core2.2 ,到现在我打算用.net core3.1对以前学的东西做个总结。
架构还是典型的三层架构，只不过为了低耦合层与层之间依赖接口而已。首先介绍整体结构：
接下来我们就要一点一点的把架构搭建起来了：
在appsettings.json配置数据库连接对象，这里用sqlserver2019数据库，注意：.net core3.1以后选用sqlserver数据库一定要用sqlserver2012以上的版本，不然能连接，但是EF模型映射的时候取数据会异常。数据库我用的是本地数据库
{
"ConnectionStrings": {
"SmartNetConnStr": "Server=LAPTOP-FOJA6HBQ\\SQLEXPRESS;uid=sa;pwd=123;Database=CoreNet;MultipleActiveResultSets=true;"
},
//rides后面会说
"RedisCaching": {
"Enabled": true,
"RedisConnectionString": "127.0.0.1:6379"
},
"Logging": {
"LogLevel": {
"Default": "Warning"
}
},
"AllowedHosts": "*"
}
接下来就是数据库的上下文：
using Core.Net.Model;
using Core.Net.Model.System;
using Microsoft.EntityFrameworkCore;
namespace Core.Net.Common.Core.Net.Data
{
public class CoreNetDBContext : DbContext
{
/// <summary>
/// 设置EF数据库链接字符串
/// </summary>
public static string DbConnStr { get; set; }
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
}
/// <summary>
/// DbContext 初始化时调用
/// </summary>
/// <param name="optionsBuilder"></param>
[System.Obsolete]
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
//optionsBuilder.UseSqlServer(@"Server=(localdb)\mssqllocaldb;database=NotifyBird;Trusted_Connection=True;");
//配置数据链接
optionsBuilder.UseSqlServer(DbConnStr);
}
}
然后在startup中注册：
//1、EF设置字符串初始化模式
CoreNetDBContext.DbConnStr = Configuration.GetConnectionString("SmartNetConnStr");
到这里数据库配置就完成了。
接下来我们定义每一层的基类：
IBaseRepository:
using Core.Net.Common.Core.Net.Core;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Linq.Expressions;
using System.Text;

{

{
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> 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();
}
}

Model:这里先放一个用户实体：
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
using System.Text;
namespace Core.Net.Model.System
{
[Table("CoreNetSystemUser")]
public class CoreNetSystemUser
{
[Key]
public int UserId { get; set; }
public string UserName { get; set; }
public string Passward { get; set; }
public string RealName { get; set; }
public int RoleId { get; set; }
public int DepartId { get; set; }
public string PushId { get; set; }
public int Sex { get; set; }
public string Email { get; set; }
public string Phone { get; set; }
public int IsUse { get; set; }
public DateTime? AddTime { get; set; }
public DateTime? UpdateTime { get; set; }
public string UpdateIP { get; set; }
}
}
具体使用，以用户类为例：
ICoreNetSystemUserRespository：
using Core.Net.Model.System;
using System;
using System.Collections.Generic;
using System.Text;
namespace Core.Net.IRepository
{
public interface ICoreNetSystemUserRespository : IBaseRepository<CoreNetSystemUser>
{
}
}
CoreNetSystemUserRespository：
using Core.Net.IRepository;
using Core.Net.Model.System;
using System;
using System.Collections.Generic;
using System.Text;
namespace Core.Net.Repository
{
public class CoreNetSystemUserRespository : BaseRepository<CoreNetSystemUser>, ICoreNetSystemUserRespository
{
}
}
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;
}
}
}
到这里一个简单的架构已经成型了，至于怎末使用后续在加入Layui前端框架的时候会详细说明。
这篇关于.Net Core3.1 MVC + EF Core+ AutoFac+LayUI+Sqlserver的框架搭建--------基础架构的文章就介绍到这儿，希望我们推荐的文章对大家有所帮助，也希望大家多多支持为之网！
