EFCore框架
一、创建项目
1. 表示层 解决方案名：ZhouYu.Market 、ZhouYu.Market.Web
2. 业务层 ZhouYu.Market.Service
3. 数据访问层 ZhouYu.Market.Repository
4. 实体层 ZhouYu.Market.Model
5. 公共层 ZhouYu.Market.Infrastructure
6. 页面实体层---用于放Success/date ZhouYu.Market.ViewModel
7. 组件层----服务 ZhouYu.Market.Components
8. 第三方--短信
9. WebApi
注意:
1. 除表示层创建为Web项目、其他层皆为.NETCore类库
2. 框架搭好之后每个层添加所用到的引用
二、实体层操作
2.1 在实体层添加AdminInfo管理员类（vs版本2.1直接添加、3.0版本用命令执行）
/// <summary>
/// 管理员信息表
/// </summary>
public class AdminInfo
{
/// <summary>
/// 管理员Id
/// </summary>
[Key]
public int AdminId { get; set; }
/// <summary>
/// 真实姓名
/// </summary>
[MaxLength(50)]
public string RealName { get; set; }
/// <summary>
/// 登录名
/// </summary>
public string LoginName { get; set; }
/// <summary>
/// 登录密码
/// </summary>
public string LoginPwd { get; set; }
/// <summary>
/// 性别
/// </summary>
public short Sex { get; set; }
/// <summary>
/// 手机号
/// </summary>
public Int64 Telphone { get; set; }
/// <summary>
/// 邮箱
/// </summary>
public string Email { get; set; }
/// <summary>
/// 角色Id
/// </summary>
public int RoleId { get; set; }
/// <summary>
/// 备注
/// </summary>
public string Remark { get; set; }
/// <summary>
/// 年龄
/// </summary>
public int Age { get; set; }
/// <summary>
/// 创建时间
/// </summary>
public DateTime CreateTime { get; set; }
/// <summary>
/// 最后一次登录时间
/// </summary>
public DateTime LastLoginTime { get; set; }
/// <summary>
/// 登录时间
/// </summary>
public DateTime LoginTime { get; set; }
/// <summary>
/// 修改时间
/// </summary>
public DateTime UpdateTime { get; set; }
/// <summary>
/// QQ
/// </summary>
public string QQ { get; set; }
/// <summary>
/// 状态1：启用 0：禁用
/// </summary>
public short Status { get; set; }
}
2.2 打开Nuget管理窗口
2.3 在实体层安装Nuget包
Install-Package Microsoft.EntityFrameworkCore.SqlServer -version 2.1.1 Install-Package Microsoft.EntityFrameworkCore.Tools -version 2.1.1 Install-Package Microsoft.EntityFrameworkCore.SqlServer.Design
2.4 创建一个MarketContext类
public class MarketContext: DbContext //管理上下文类---设置连接字符串
{
public DbSet<AdminInfo> AdminInfo { get; set; }
protected override void OnConfiguring(DbContextOptionsBuilder dbContextOptionsBuilder)
{
dbContextOptionsBuilder.UseSqlServer("server=localhost;database=Market;uid=sa;pwd=sa");
}
}
2.5 数据迁移
Add-Migration build125、Update-Database

/// </summary>
/// <param name="options"></param>
public SyDbContext(DbContextOptions<SyDbContext> options) : base(options)
{
}
public virtual DbSet<AdminInfo> AdminInfo { get; set; }
}
注意：此时删掉实体层中MarketContext类与Migrations文件夹、同时在表示层中appsettings.json文件添加配置连接字符串
"ConnectionStrings": {
"ConnectionString": "server=localhost;database=Market;uid=sa;pwd=sa"
}
3.4 在表示层Program类中添加读取配置文件的代码
public class Program
{
public static void Main(string[] args)
{
CreateWebHostBuilder(args).Build().Run();
}
public static IWebHostBuilder CreateWebHostBuilder(string[] args)
{
//读取配置文件
var configuration = new ConfigurationBuilder()
.SetBasePath(Environment.CurrentDirectory)
.AddJsonFile("appsettings.json")//读取配置文件，获取启动的端口号
.Build();
return WebHost.CreateDefaultBuilder(args)
.UseConfiguration(configuration)
.UseStartup<Startup>();
}
//=>
//WebHost.CreateDefaultBuilder(args)
// .UseStartup<Startup>();
}
3.5 在表示层Startup类ConfigureServices方法中添加代码
//数据库上下文注入 使用DbContext池，提高性能 services.AddDbContextPool<SyDbContext>(options => options.UseSqlServer(Configuration.GetConnectionString("ConnectionString")));
四、组件层操作
注意：（添加Nuget包Microsoft.Extensions.DependencyInjection）
4.1 在组件层中新建Extensions文件夹其中添加DataServiceExtension类
public static class DataServiceExtension { /// <summary> /// 注入数据 /// </summary> /// <param name="services"></param> public static IServiceCollection AddDataService(this IServiceCollection services) { #region 范围依赖注入 services.AddScoped<IAdminInfoService, AdminInfoService>(); #endregion return services; } }
4.2 在表示层Startup类ConfigureServices方法中添加数据服务注入代码
//数据服务注入 services.AddDataService();
五、公共层操作
5.1 在公共层新建Encrytp文件夹其中添加MD5Encrypt类
public class MD5Encrypt { /// <summary> /// MD5加密 /// </summary> /// <param name="source"></param> /// <returns></returns> public static string Encrypt(string source) { if (string.IsNullOrEmpty(source)) return string.Empty; HashAlgorithm provider = CryptoConfig.CreateFromName("MD5") as HashAlgorithm; byte[] bytes = Encoding.UTF8.GetBytes(source);//这里需要区别编码的 byte[] hashValue = provider.ComputeHash(bytes); StringBuilder sb = new StringBuilder(); for (int i = 0; i < 16; i++) { sb.Append(hashValue[i].ToString("x2")); } return sb.ToString(); } }
5.2 添加一个EnumExtension类
/// <summary> /// 枚举扩展属性 /// </summary> public static class EnumExtension { private static Dictionary<string, Dictionary<string, string>> enumCache; private static Dictionary<string, Dictionary<string, string>> EnumCache { get { if (enumCache == null) { enumCache = new Dictionary<string, Dictionary<string, string>>(); } return enumCache; } set { enumCache = value; } } /// <summary> /// 获得枚举提示文本 /// </summary> /// <param name="en"></param> /// <returns></returns> public static string GetEnumText(this Enum en) { string enString = string.Empty; if (null == en) return enString; var type = en.GetType(); enString = en.ToString(); if (!EnumCache.ContainsKey(type.FullName)) { var fields = type.GetFields(); Dictionary<string, string> temp = new Dictionary<string, string>(); foreach (var item in fields) { var attrs = item.GetCustomAttributes(typeof(TextAttribute), false); if (attrs.Length == 1) { var v = ((TextAttribute)attrs[0]).Value; temp.Add(item.Name, v); } } EnumCache.Add(type.FullName, temp); } if (EnumCache[type.FullName].ContainsKey(enString)) { return EnumCache[type.FullName][enString]; } return enString; } } public class TextAttribute : Attribute { public TextAttribute(string value) { Value = value; } public string Value { get; set; } }
六、业务层操作
6.1 在业务层新建IService文件夹其中添加IAdminInfoService接口
public interface IAdminInfoService { //验证登录 ResponseResult ValidateLogin(string userName, string userPwd); }
6.2 在业务层新建Service文件夹其中添加AdminInfoService类
public class AdminInfoService : RepositoryBase<AdminInfo>, IAdminInfoService { /// <summary> /// 构造函数 /// </summary> /// <param name="syDbContext"></param> public AdminInfoService(SyDbContext syDbContext) : base(syDbContext) { } /// <summary> /// 验证登录 /// </summary> /// <param name="userName"></param> /// <param name="userPwd"></param> /// <returns></returns> public ResponseResult ValidateLogin(string userName, string userPwd) { ResponseResult responseResult = new ResponseResult(); //MD5加密 var md5 = MD5Encrypt.Encrypt(userPwd); //查询 var model = GetModel(a => a.LoginName == userName && a.LoginPwd == md5); if (model != null) { responseResult.success = true; responseResult.data = model; } else { responseResult.success = false; responseResult.msg = "账号或密码错误！"; } return responseResult; } }
七、页面实体层操作
7.1 在页面实体层添加一个ResponseEnum类
public enum ResponseEnum { /// <summary> /// 请求(或处理)成功 /// </summary> [Text("请求(或处理)成功")] Status = 200, //请求(或处理)成功 /// <summary> /// 内部请求出错 /// </summary> [Text("内部请求出错")] Error = 500, //内部请求出错 /// <summary> /// 未授权标识 /// </summary> [Text("未授权标识")] Unauthorized = 401,//未授权标识 /// <summary> /// 请求参数不完整或不正确 /// </summary> [Text("请求参数不完整或不正确")] ParameterError = 400,//请求参数不完整或不正确 /// <summary> /// 请求TOKEN失效 /// </summary> [Text("请求TOKEN失效")] TokenInvalid = 403,//请求TOKEN失效 /// <summary> /// HTTP请求类型不合法 /// </summary> [Text("HTTP请求类型不合法")] HttpMehtodError = 405,//HTTP请求类型不合法 /// <summary> /// HTTP请求不合法,请求参数可能被篡改 /// </summary> [Text("HTTP请求不合法,请求参数可能被篡改")] HttpRequestError = 406,//HTTP请求不合法 /// <summary> /// 该URL已经失效 /// </summary> [Text("该URL已经失效")] URLExpireError = 407,//HTTP请求不合法 }
7.2 在页面实体层添加一个ResponseResult类
/// <summary> /// 请求返回统一格式 /// </summary> public class ResponseResult { /// <summary> /// 构造函数 /// </summary> public ResponseResult() { } /// <summary> /// 构造函数 /// </summary> /// <param name="success">是否成功</param> /// <param name="code">状态码</param> /// <param name="list">数据</param> /// <param name="recordCount">总记录数</param> public ResponseResult(bool success, string msg, int code, dynamic list, int recordCount) { this.success = success; this.msg = msg; this.code = code; this.data = list; this.count = recordCount; } /// <summary> /// 构造函数，成功返回列表 /// </summary> /// <param name="list">数据</param> /// <param name="recordCount">总记录数</param> public ResponseResult(dynamic list, int recordCount) { this.success = true; this.data = list; this.count = recordCount; } /// <summary> /// 构造函数，操作是否成功 /// </summary> /// <param name="list">数据</param> /// <param name="code">状态码</param> /// <param name="recordCount">总记录数</param> public ResponseResult(bool success, int code, string msg) { this.success = success; this.code = code; this.msg = msg; } /// <summary> /// 构造函数，操作是否成功 /// </summary> /// <param name="list">数据</param> /// <param name="recordCount">总记录数</param> public ResponseResult(bool success, string msg) { this.success = success; if (success) { this.code = 200; } else { this.code = 500; } this.msg = msg; } /// <summary> /// 是否成功 /// </summary> public bool success { get; set; } = true; /// <summary> /// 状态码 /// </summary> public int code { set; get; } = 0; /// <summary> /// 总记录数 /// </summary> public int count { set; get; } = 0; /// <summary> /// 数据 /// </summary> public dynamic data { set; get; } /// <summary> /// 返回信息 /// </summary> public string msg { set; get; } /// <summary> /// 序列化为字符串 /// </summary> /// <returns></returns> public override string ToString() { return Newtonsoft.Json.JsonConvert.SerializeObject(this); } }
7.3 在表示层Startup类ConfigureServices方法中添加全局配置Json序列化处理代码
// 注册MVC到Container services.AddMvc() //全局配置Json序列化处理 .AddJsonOptions(options => { options.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore; options.SerializerSettings.ContractResolver = new DefaultContractResolver(); }).SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
八、表示层操作
8.1 在wwwroot中的文件夹加入所用到的js、css、images、layui文件夹
8.2 在Controllers文件夹中添加一个AccountController控制器
public class AccountController : Controller { //接口注入 public IAdminInfoService _adminInfoService; public AccountController(IAdminInfoService adminInfoService) { _adminInfoService = adminInfoService; } /// <summary> /// 登录页 /// </summary> /// <returns></returns> public IActionResult Login() { return View(); } /// <summary> /// 验证登录 /// </summary> /// <returns></returns> public IActionResult ValidateLogin(string userName, string userPwd) { //调用验证登录方法 var result = _adminInfoService.ValidateLogin(userName, userPwd); return Json(result); } /// <summary> /// 退出登录 /// </summary> /// <returns></returns> public IActionResult LoginOut() { ViewData["Message"] = "Your contact page."; return View(); } }
8.3 在View文件夹中新建Account文件夹其次再添加一个Login.cshtml页面
<!DOCTYPE html> <html> <head lang="en"> <meta charset="UTF-8"> <title>系统登录 - 超市账单管理系统</title> <link rel="stylesheet" href="~/css/style.css" /> <link rel="stylesheet" href="~/lib/layui-v2.5.4/layui/css/modules/layer/default/layer.css" /> <script type="text/javascript" src="~/lib/jquery/dist/jquery.min.js"></script> <script type="text/javascript" src="~/lib/layui-v2.5.4/layui/lay/modules/layer.js"></script> </head> <body class="login_bg"> <section class="loginBox"> <header class="loginHeader"> <h1>超市账单管理系统</h1> </header> <section class="loginCont"> <form class="loginForm" action="welcome.html"> <div class="inputbox"> <label for="user">用户名：</label> <input id="user" type="text" name="username" placeholder="请输入用户名" required /> </div> <div class="inputbox"> <label for="mima">密码：</label> <input id="mima" type="password" name="password" placeholder="请输入密码" required /> </div> <div class="subBtn"> <input type="submit" value="登录" /> <input type="reset" value="重置" /> </div> </form> </section> </section> </body> </html>
