EF框架实现登录（记住密码+首页欢迎）+列表功能（增删改查）+过滤器
2024-03-21 19:00:44
一、登录
1、设计数据库
CREATE TABLE [dbo].[AdminUser]([Id] [int] IDENTITY(1,1) NOT NULL,[Name] [varchar](50) NULL,[Pwd] [varchar](36) NULL,[Email] [varchar](200) NULL
)2、创建MVC框架
3、创建实体类–建立实体模型
创建Operate类
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;namespace WebApplication4.Model
{public class Operate{public bool Success { get; set; }}
}右键–>添加类–>ADO.NET实体模型–>配置连接–>选择需要的数据库生成即可
效果：
4.创建数据库访问层–>生成EF6生成器
效果：
添加EF引用：
引用-->右键-->NuGet包添加引用 EntityFramework
添加类BaseRepository：
using System;
using System.Collections.Generic;
using System.Data.Entity;
using System.Linq;
using System.Linq.Expressions;
using System.Text;
using System.Threading.Tasks;namespace WebApplication4.DAL
{public class BaseRepository<T, TS> where T : classwhere TS : DbContext, new(){private DbContext db = DbContextFactory<TS>.GetCurrentDbContext();//添加单条记录public bool Add(T entily){db.Set<T>().Add(entily);return db.SaveChanges() > 0;}//添加多条记录public bool AddList(List<T> entily){db.Set<T>().AddRange(entily);return db.SaveChanges() > 0;}//删除public bool DELETE(T entily){db.Entry(entily).State = EntityState.Deleted;return db.SaveChanges() > 0;}//删除多个public bool BDELETE(List<T> entiles){db.Set<T>().RemoveRange(entiles);return db.SaveChanges() > 0;}//根据id删除public bool BatchDELETE(params int[] entiles){foreach (var id in entiles){var entity = db.Set<T>().Find(id);if (entity != null){db.Set<T>().Remove(entity);}}return db.SaveChanges() > 0;}//修改public bool Update(T entily){db.Entry(entily).State = EntityState.Modified;return db.SaveChanges() > 0;}//查询一个集合public List<T> QueryList(Expression<Func<T, bool>> lambdaExpression){return db.Set<T>().Where(lambdaExpression).ToList();}//查询一个对象，如果没有返回nullpublic T Query(Expression<Func<T, bool>> lambdaExpression){return db.Set<T>().SingleOrDefault(lambdaExpression);}public bool Exists(Expression<Func<T, bool>> lambdaExpression){return db.Set<T>().Any(lambdaExpression);}//分页查询public List<T> QuerypageList<S>(int pageIndex, int pageSize, Expression<Func<T, bool>> wheredma, Expression<Func<T, S>> orderbyLamba, out int count, bool isAc = true){count = db.Set<T>().Where(wheredma).Count();if (!isAc){return db.Set<T>().Where(wheredma).OrderByDescending(orderbyLamba).Skip((pageIndex - 1) * pageSize).Take(pageSize).ToList();}else{return db.Set<T>().Where(wheredma).OrderBy(orderbyLamba).Skip((pageIndex - 1) * pageSize).Take(pageSize).ToList();}}}
添加类DbContextFactory
using System;
using System.Collections.Generic;
using System.Data.Entity;
using System.Linq;
using System.Runtime.Remoting.Messaging;
using System.Text;
using System.Threading.Tasks;namespace WebApplication4.DAL
{public class DbContextFactory<TS> where TS : DbContext, new(){public static DbContext GetCurrentDbContext(){var dbContext = CallContext.GetData(typeof(TS).Name) as DbContext;if (dbContext != null){return dbContext;}else{dbContext = new TS();CallContext.SetData(typeof(TS).Name, dbContext);return dbContext;}}}}编辑Model1.Context.tt文件
<#@ template language="C#" debug="false" hostspecific="true"#>
<#@ include file="EF.Utility.CS.ttinclude"#><#@output extension=".cs"#><#MetadataLoader loader = new MetadataLoader(this);
//注意修改路径，直接拖实体模型即可
string inputFile = @"..\\WebApplication4.Model\Model1.edmx";
EdmItemCollection ItemCollection = loader.CreateEdmItemCollection(inputFile);
#>
//注意修改相应的命名空间
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using WebApplication4.Model;namespace WebApplication4.Model
{<#
foreach (EntityType entity in ItemCollection.GetItems<EntityType>().OrderBy(e => e.Name))
{
#>
//注意PermissionEntities是实体模型中 : base("name=PermissionEntities")要改成相应的public partial class <#=entity.Name#>Repository : BaseRepository<<#=entity.Name#>,PermissionEntities>{}
<#}#>}
4、业务逻辑层：
添加EF引用：
引用-->右键-->NuGet包添加引用 EntityFramework
在页面添加using引用
添加基类：BaseService类
using System;
using System.Collections.Generic;
using System.Linq.Expressions;
using WebApplication4.DAL;
using WebApplication4.Model;namespace WebApplication4.BLL
{public class BaseService<T> where T : class{private BaseRepository<T, PermissionEntities> baseRepository = new BaseRepository<T, PermissionEntities>();//添加单条记录public virtual bool Add(T entily){return baseRepository.Add(entily);}//添加多条记录public virtual bool AddList(List<T> entily){return baseRepository.AddList(entily);}//删除public virtual bool DELETE(T entily){return baseRepository.DELETE(entily);}//删除多个public virtual bool BDELETE(List<T> entiles){return baseRepository.BDELETE(entiles);}//根据id删除public bool BatchDELETE(params int[] entiles){return baseRepository.BatchDELETE(entiles);}//修改public virtual bool Update(T entily){return baseRepository.Update(entily);}//查询一个集合public virtual List<T> QueryList(Expression<Func<T, bool>> lambdaExpression){return baseRepository.QueryList(lambdaExpression);}//查询一个对象，如果没有返回nullpublic virtual T Query(Expression<Func<T, bool>> lambdaExpression){return baseRepository.Query(lambdaExpression);}public virtual bool Exists(Expression<Func<T, bool>> lambdaExpression){return baseRepository.Exists(lambdaExpression);}//分页查询public virtual List<T> QuerypageList<S>(int pageIndex, int pageSize, Expression<Func<T, bool>> wheredma, Expression<Func<T, S>> orderbyLamba, out int count, bool isAc = true){return baseRepository.QuerypageList(pageIndex, pageSize, wheredma, orderbyLamba, out count, isAc);}}}
5、创建业务逻辑层
添加AdminInfoService
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using WebApplication4.Model;namespace WebApplication4.BLL.Service
{public class AdminInfoService : BaseService<AdminUser>{}
}
6、UI层
在Models文件夹添加上下文
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.SessionState;
using WebApplication4.Model;namespace WebApplication4.Models
{/// <summary>/// 管理员的上下文/// </summary>public class AdminContext{/// <summary>/// 会话的key/// </summary>private string SessionKey = "ADMIN_KEY";/// <summary>/// 静态的上下文/// </summary>public static AdminContext adminContext = new AdminContext();/// <summary>///会话状态/// </summary>public HttpSessionState httpSessionState => HttpContext.Current.Session;/// <summary>/// 用户对象/// </summary>public AdminUser adminInfo{get{return httpSessionState[SessionKey] as AdminUser;}set{httpSessionState[SessionKey] = value;}}}
}
创建一个空的控制器LoginController
using System;
using System.Collections.Generic;
using System.Linq;
using System.Linq.Expressions;
using System.Web;
using System.Web.Mvc;
using WebApplication4.BLL.Service;
using WebApplication4.Model;
using WebApplication4.Models;namespace WebApplication4.Controllers
{public class LoginController : Controller{private AdminInfoService adminInfoService = new AdminInfoService();#region 登录public JsonResult Login(AdminUser adminUser, bool check){Operate operate = new Operate();AdminUser adminUsers = new AdminUser();Expression<Func<AdminUser, bool>> lambdaExpression = a => a.Name == adminUser.Name && a.Password == adminUser.Password;adminUsers = adminInfoService.Query(lambdaExpression);operate.Success = adminUsers != null;if (adminUsers != null){operate.Success = true;//存储session值AdminContext.adminContext.adminInfo = adminUsers;//如果选中保存密码则存储cookieif (check){//存储cookie//创建一个Cookie对象HttpCookie httpCookie = new HttpCookie("CookieName");//设置Cookie的值httpCookie.Values.Add("Name", adminUsers.Name);httpCookie.Values.Add("Password", adminUsers.Password);httpCookie.Values.Add("DateTime", DateTime.Now.AddDays(7).ToString("yyyy-MM-dd HH:mm:ss"));//设置Cookie的过期时间httpCookie.Expires = DateTime.Now.AddDays(7);System.Web.HttpContext.Current.Response.Cookies.Add(httpCookie);}}return Json(operate);}#endregion}
}
Home控制器操作
using WebApplication4.Model
using WebApplication4.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;namespace Admin.Controllers
{public class HomeController : Controller{public ActionResult Index(){return View();}public ActionResult Login() {//取出Cookie保存的信息HttpCookie cookie = System.Web.HttpContext.Current.Request.Cookies.Get("CookieName");if (cookie != null){string name = cookie["Name"];//等同于string name = cookie.Values.Get("UserName");string pwd = cookie["Password"];//DateTime time = DateTime.Parse(cookie["DateTime"]);if (name != null && pwd != null && DateTime.Parse(cookie["DateTime"]) != null && DateTime.Now < DateTime.Parse(cookie["DateTime"])){//将Cookie中的值赋给上下文session 使其在不登录时页面也能够显示AdminContext.adminContext.adminInfo = new AdminUser(){Name = name,Password = pwd};return Redirect("/Home/Index");}}return View();}}
}

二、列表的增删改查
1、在实体层中添加PageListResult类
public class PageListResult<T>{public int code { get; set; }public string msg { get; set; }public int count { get; set; }public List<T> data { get; set; }}2、业务逻辑层：创建AdminService类：
public class AdminService : BaseService<AdminUser>, IDenpendecy{}3、控制器：
public class AdminController : Controller{public AdminService user = new AdminService ();#region 显示查询public ActionResult Display(int page, int limit, string UserName){//PageListResult类PageListResult<AdminUser> pageListResult = new PageListResult<AdminUser>();//设值pageListResult.code = 0;pageListResult.msg = string.Empty;//数据总数int count = 0;//where条件（ling表达式）Expression<Func<AdminUser, bool>> Wherelambda = c => true;if (!string.IsNullOrEmpty(UserName)){Wherelambda = a => a.Name.Contains(UserName);}//设置OrderBy排序的字段Expression<Func<AdminUser, int>> OrderBylambda = c => c.Id;//调用QuerypageList方法查询数据pageListResult.data = user.QuerypageList(page, limit, Wherelambda, OrderBylambda, out count);//返回结果return Json(pageListResult, JsonRequestBehavior.AllowGet);}#endregion#region 删除public ActionResult Delete(AdminUser adminUser){//Operate类Operate operate = new Operate();//调用DELETE方法删除数据operate.Success = user.DELETE(adminUser);return Json(operate);}#endregion#region 添加/修改public ActionResult Addhh(AdminUser adminUser){//Operate类Operate operate = new Operate();//判断Id，是修改还是添加if (adminUser.Id != 0){//调用Update方法修改数据operate.Success = user.Update(adminUser);}else{//调用Add方法添加数据operate.Success = user.Add(adminUser);}return Json(operate);}#endregion}4、UI层：

</script>过滤器：
在UI层添加一个文件夹Attributes
添加行为过滤器 ActionAttribute：

配置：异常过滤器和行为过滤器
public static void RegisterGlobalFilters(GlobalFilterCollection filters){//异常过滤器filters.Add(new ExceptionAttribute());//行为过滤器filters.Add(new ActionAttribute());}在Home控制器中使用权限过滤器
public class HomeController : Controller{[PermissionAttribute]public ActionResult Index(){return View();}
