分类: 文章 • 2024-02-16 07:43:10

一,摘要

本篇文章我们将使用ASP.NET MVC3,Razor,EF Code First创建Web应用程序.覆盖Unity2.0,泛型Repository以及EF Code First的工作单元.需要使用到的工具如下:

1.ASP.NET MVC 3
2.EF Code First CTP5
3.Unity2.0

二,安装工具

安装好Visual Studio2010后继续安装MVC3(http://www.microsoft.com/downloads/en/details.aspx?FamilyID=d2928bc1-f48c-4e95-a064-2a455a22c8f6)，NuGet(http://nuget.codeplex.com/)

三,建立程序

1.打开Visual Studio2010选择选择新建ASP.NET MVC 3 Web Application,取名叫MVC3DIApplication:

三,建立领域模型

1.添加一个类库,命名MVC3DIApplication.Domain,然后在里面添加文件夹Entities,在文件夹里添加实体模型类
Category.cs: 

   1: using System;
<!--CRLF--> 
   2: using System.Collections.Generic;
<!--CRLF--> 
   3: using System.Linq;
<!--CRLF--> 
   4: using System.Web;
<!--CRLF--> 
   5: using System.ComponentModel.DataAnnotations;
<!--CRLF--> 
   6:
<!--CRLF--> 
   7: namespace MyFinance.Domain
<!--CRLF--> 
   8: {
<!--CRLF--> 
   9:     public class Category
<!--CRLF--> 
  10:     {
<!--CRLF--> 
  11:
<!--CRLF--> 
  12:         public int CategoryId { get; set; }
<!--CRLF--> 
  13:
<!--CRLF--> 
  14:         [Required(ErrorMessage = "Name Required")]
<!--CRLF--> 
  15:         [StringLength(25, ErrorMessage = "Must be less than 25 characters")]
<!--CRLF--> 
  16:         public string Name { get; set;}
<!--CRLF--> 
  17:         public string Description { get; set; }
<!--CRLF--> 
  18:         public virtual ICollection<expense> Expenses { get; set; }</expense>
<!--CRLF--> 
  19:     }
<!--CRLF--> 
  20: }
<!--CRLF-->

Expense.cs: 

   1: using System;
<!--CRLF--> 
   2: using System.Collections.Generic;
<!--CRLF--> 
   3: using System.Linq;
<!--CRLF--> 
   4: using System.Text;
<!--CRLF--> 
   5:
<!--CRLF--> 
   6: namespace MVC3DIApplication.Domain.Entities
<!--CRLF--> 
   7: {
<!--CRLF--> 
   8:     public class Expense
<!--CRLF--> 
   9:     {
<!--CRLF--> 
  10:         public int ExpenseId { get; set; }
<!--CRLF--> 
  11:         public string Transaction { get; set; }
<!--CRLF--> 
  12:         public DateTime Date { get; set; }
<!--CRLF--> 
  13:         public double Amount { get; set; }
<!--CRLF--> 
  14:         public int CategoryId { get; set; }
<!--CRLF--> 
  15:         public virtual Category Category { get; set; }
<!--CRLF--> 
  16:     }
<!--CRLF--> 
  17: }
<!--CRLF-->


2.继续添加类库MVC3DIApplication.Data,在其下新建一个叫MyFinanceContext的类,该类继承自DbContext,用来映射我们的模型到数据库表 

   1: using System;
<!--CRLF--> 
   2: using System.Collections.Generic;
<!--CRLF--> 
   3: using System.Linq;
<!--CRLF--> 
   4: using System.Text;
<!--CRLF--> 
   5: using System.Data.Entity;
<!--CRLF--> 
   6: using MVC3DIApplication.Domain.Entities;
<!--CRLF--> 
   7:
<!--CRLF--> 
   8: namespace MVC3DIApplication.Data
<!--CRLF--> 
   9: {
<!--CRLF--> 
  10:     public class MyFinanceContext : DbContext
<!--CRLF--> 
  11:     {
<!--CRLF--> 
  12:         public MyFinanceContext() : base("MyFinance") { }
<!--CRLF--> 
  13:         public DbSet<category> Categories { get; set; }</category>
<!--CRLF--> 
  14:         public DbSet<expense> Expenses { get; set; }</expense>
<!--CRLF--> 
  15:         public virtual void Commit()
<!--CRLF--> 
  16:         {
<!--CRLF--> 
  17:             base.SaveChanges();
<!--CRLF--> 
  18:         }
<!--CRLF--> 
  19:     }
<!--CRLF--> 
  20: }
<!--CRLF-->

3.修改Web.comfig: 

   1: connectionStrings>
<!--CRLF--> 
   2:       add name="MyFinance" connectionString="data source=./MSSQLSERVER2008;Initial Catalog=MVC3DI;Persist Security Info=True;User ID=sa;Password=suzhi921;" providerName="System.Data.SqlClient" />
<!--CRLF--> 
   3:       add name="ApplicationServices" connectionString="data source=./SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient" />
<!--CRLF--> 
   4:     connectionStrings>
<!--CRLF-->

四,建立泛型Repository

MVC3DIApplication.Data类库下建立Infrastructure文件夹,在里面添加类IRepository.cs: 

   1: using System;
<!--CRLF--> 
   2: using System.Collections.Generic;
<!--CRLF--> 
   3: using System.Linq;
<!--CRLF--> 
   4: using System.Text;
<!--CRLF--> 
   5:
<!--CRLF--> 
   6: namespace MVC3DIApplication.Data.Infrastructure
<!--CRLF--> 
   7: {
<!--CRLF--> 
   8:     public interface IRepository<t><span style="color: #0000ff">where</span> T : <span style="color: #0000ff">class</span></t>
<!--CRLF--> 
   9:     {
<!--CRLF--> 
  10:         void Add(T entity);
<!--CRLF--> 
  11:         void Delete(T entity);
<!--CRLF--> 
  12:         void Delete(Func<t boolean> predicate);</t>
<!--CRLF--> 
  13:         T GetById(long Id);
<!--CRLF--> 
  14:         T Get(Func<t boolean><span style="color: #0000ff">where</span>);</t>
<!--CRLF--> 
  15:         IEnumerable<t> GetAll();</t>
<!--CRLF--> 
  16:         IEnumerable<t> GetMany(Func<t style="color: #0000ff">bool&gt; <span style="color: #0000ff">where</span>);</t></t>
<!--CRLF--> 
  17:     }
<!--CRLF--> 
  18: }
<!--CRLF-->

IDatabaseFactory.cs: 

   1: using System;
<!--CRLF--> 
   2: using System.Collections.Generic;
<!--CRLF--> 
   3: using System.Linq;
<!--CRLF--> 
   4: using System.Text;
<!--CRLF--> 
   5:
<!--CRLF--> 
   6: namespace MVC3DIApplication.Data.Infrastructure
<!--CRLF--> 
   7: {
<!--CRLF--> 
   8:     public interface IDatabaseFactory : IDisposable
<!--CRLF--> 
   9:     {
<!--CRLF--> 
  10:         MyFinanceContext Get();
<!--CRLF--> 
  11:     }
<!--CRLF--> 
  12: }
<!--CRLF-->

RepositoryBase.cs: 

   1: using System;
<!--CRLF--> 
   2: using System.Collections.Generic;
<!--CRLF--> 
   3: using System.Linq;
<!--CRLF--> 
   4: using System.Text;
<!--CRLF--> 
   5: using System.Data.Entity;
<!--CRLF--> 
   6:
<!--CRLF--> 
   7: namespace MVC3DIApplication.Data.Infrastructure
<!--CRLF--> 
   8: {
<!--CRLF--> 
   9:     public abstract class RepositoryBase<t><span style="color: #0000ff">where</span> T : <span style="color: #0000ff">class</span></t>
<!--CRLF--> 
  10:     {
<!--CRLF--> 
  11:         private MyFinanceContext dataContext;
<!--CRLF--> 
  12:         private readonly IDbSet<t> dbset;</t>
<!--CRLF--> 
  13:         protected RepositoryBase(IDatabaseFactory databaseFactory)
<!--CRLF--> 
  14:         {
<!--CRLF--> 
  15:             DatabaseFactory = databaseFactory;
<!--CRLF--> 
  16:             dbset = DataContext.Set<t>();</t>
<!--CRLF--> 
  17:         }
<!--CRLF--> 
  18:
<!--CRLF--> 
  19:         protected IDatabaseFactory DatabaseFactory
<!--CRLF--> 
  20:         {
<!--CRLF--> 
  21:             get;
<!--CRLF--> 
  22:             private set;
<!--CRLF--> 
  23:         }
<!--CRLF--> 
  24:
<!--CRLF--> 
  25:         protected MyFinanceContext DataContext
<!--CRLF--> 
  26:         {
<!--CRLF--> 
  27:             get { return dataContext ?? (dataContext = DatabaseFactory.Get()); }
<!--CRLF--> 
  28:         }
<!--CRLF--> 
  29:         public virtual void Add(T entity)
<!--CRLF--> 
  30:         {
<!--CRLF--> 
  31:             dbset.Add(entity);
<!--CRLF--> 
  32:         }
<!--CRLF--> 
  33:
<!--CRLF--> 
  34:         public virtual void Delete(T entity)
<!--CRLF--> 
  35:         {
<!--CRLF--> 
  36:             dbset.Remove(entity);
<!--CRLF--> 
  37:         }
<!--CRLF--> 
  38:         public void Delete(Func<t boolean><span style="color: #0000ff">where</span>)</t>
<!--CRLF--> 
  39:         {
<!--CRLF--> 
  40:             IEnumerable<t> objects = dbset.Where<t>(<span style="color: #0000ff">where</span>).AsEnumerable();</t></t>
<!--CRLF--> 
  41:             foreach (T obj in objects)
<!--CRLF--> 
  42:                 dbset.Remove(obj);
<!--CRLF--> 
  43:         }
<!--CRLF--> 
  44:         public virtual T GetById(long id)
<!--CRLF--> 
  45:         {
<!--CRLF--> 
  46:             return dbset.Find(id);
<!--CRLF--> 
  47:         }
<!--CRLF--> 
  48:
<!--CRLF--> 
  49:         public virtual IEnumerable<t> GetAll()</t>
<!--CRLF--> 
  50:         {
<!--CRLF--> 
  51:             return dbset.ToList();
<!--CRLF--> 
  52:         }
<!--CRLF--> 
  53:         public virtual IEnumerable<t> GetMany(Func<t style="color: #0000ff">bool&gt; <span style="color: #0000ff">where</span>)</t></t>
<!--CRLF--> 
  54:         {
<!--CRLF--> 
  55:             return dbset.Where(where).ToList();
<!--CRLF--> 
  56:         }
<!--CRLF--> 
  57:         public T Get(Func<t boolean><span style="color: #0000ff">where</span>)</t>
<!--CRLF--> 
  58:         {
<!--CRLF--> 
  59:             return dbset.Where(where).FirstOrDefault<t>();</t>
<!--CRLF--> 
  60:         }
<!--CRLF--> 
  61:     }
<!--CRLF--> 
  62: }
<!--CRLF-->

五,工作单元

工作单元主要用来维护受Business transaction影响的对象以及并发等问题
MVC3DIApplication.Data类库的Infrastructure下建立IUnitOfWork.cs: 

   1: using System;
<!--CRLF--> 
   2: using System.Collections.Generic;
<!--CRLF--> 
   3: using System.Linq;
<!--CRLF--> 
   4: using System.Text;
<!--CRLF--> 
   5:
<!--CRLF--> 
   6: namespace MVC3DIApplication.Data.Infrastructure
<!--CRLF--> 
   7: {
<!--CRLF--> 
   8:     public interface IUnitOfWork
<!--CRLF--> 
   9:     {
<!--CRLF--> 
  10:         void Commit();
<!--CRLF--> 
  11:     }
<!--CRLF--> 
  12: }
<!--CRLF-->

UnitOfWork.cs: 

   1: using System;
<!--CRLF--> 
   2: using System.Collections.Generic;
<!--CRLF--> 
   3: using System.Linq;
<!--CRLF--> 
   4: using System.Text;
<!--CRLF--> 
   5:
<!--CRLF--> 
   6: namespace MVC3DIApplication.Data.Infrastructure
<!--CRLF--> 
   7: {
<!--CRLF--> 
   8:     public class UnitOfWork : IUnitOfWork
<!--CRLF--> 
   9:     {
<!--CRLF--> 
  10:         private readonly IDatabaseFactory databaseFactory;
<!--CRLF--> 
  11:         private MyFinanceContext dataContext;
<!--CRLF--> 
  12:
<!--CRLF--> 
  13:         public UnitOfWork(IDatabaseFactory databaseFactory)
<!--CRLF--> 
  14:         {
<!--CRLF--> 
  15:             this.databaseFactory = databaseFactory;
<!--CRLF--> 
  16:         }
<!--CRLF--> 
  17:
<!--CRLF--> 
  18:         protected MyFinanceContext DataContext
<!--CRLF--> 
  19:         {
<!--CRLF--> 
  20:             get { return dataContext ?? (dataContext = databaseFactory.Get()); }
<!--CRLF--> 
  21:         }
<!--CRLF--> 
  22:
<!--CRLF--> 
  23:         public void Commit()
<!--CRLF--> 
  24:         {
<!--CRLF--> 
  25:             DataContext.Commit();
<!--CRLF--> 
  26:         }
<!--CRLF--> 
  27:     }
<!--CRLF--> 
  28: }
<!--CRLF-->

六,Category Repository

MVC3DIApplication.Data类库的下建立Repositories文件夹,里面存储我们的Repositories,下面简历CategoryRepository: 

   1: using System;
<!--CRLF--> 
   2: using System.Collections.Generic;
<!--CRLF--> 
   3: using System.Linq;
<!--CRLF--> 
   4: using System.Text;
<!--CRLF--> 
   5: using MVC3DIApplication.Data.Infrastructure;
<!--CRLF--> 
   6: using MVC3DIApplication.Domain.Entities;
<!--CRLF--> 
   7:
<!--CRLF--> 
   8: namespace MVC3DIApplication.Data.Repositories
<!--CRLF--> 
   9: {
<!--CRLF--> 
  10:     public class CategoryRepository : RepositoryBase<category>, ICategoryRepository</category>
<!--CRLF--> 
  11:     {
<!--CRLF--> 
  12:         public CategoryRepository(IDatabaseFactory databaseFactory)
<!--CRLF--> 
  13:             : base(databaseFactory)
<!--CRLF--> 
  14:         {
<!--CRLF--> 
  15:         }
<!--CRLF--> 
  16:     }
<!--CRLF--> 
  17:     public interface ICategoryRepository : IRepository<category></category>
<!--CRLF--> 
  18:     {
<!--CRLF--> 
  19:     }
<!--CRLF--> 
  20: }
<!--CRLF-->

如果我们有额外的方法,那么我们能定义在上面的Repository里.

七,使用Unity2.0

我们为Unity创建一个自定义的生命周期管理器去存储当前上下文的容器,同时创建控制器工厂 

   1: using System;
<!--CRLF--> 
   2: using System.Collections.Generic;
<!--CRLF--> 
   3: using System.Linq;
<!--CRLF--> 
   4: using System.Web;
<!--CRLF--> 
   5: using Microsoft.Practices.Unity;
<!--CRLF--> 
   6: using System.Web.Mvc;
<!--CRLF--> 
   7: using System.Web.Routing;
<!--CRLF--> 
   8:
<!--CRLF--> 
   9: namespace MVC3DIApplication.IoC
<!--CRLF--> 
  10: {
<!--CRLF--> 
  11:     public class UnityControllerFactory : DefaultControllerFactory
<!--CRLF--> 
  12:     {
<!--CRLF--> 
  13:         IUnityContainer container;
<!--CRLF--> 
  14:         public UnityControllerFactory(IUnityContainer container)
<!--CRLF--> 
  15:         {
<!--CRLF--> 
  16:             this.container = container;
<!--CRLF--> 
  17:         }
<!--CRLF--> 
  18:         protected override IController GetControllerInstance(RequestContext reqContext, Type controllerType)
<!--CRLF--> 
  19:         {
<!--CRLF--> 
  20:             IController controller;
<!--CRLF--> 
  21:             if (controllerType == null)
<!--CRLF--> 
  22:                 throw new HttpException(
<!--CRLF--> 
  23:                         404, String.Format(
<!--CRLF--> 
  24:                             "The controller for path '{0}' could not be found" +
<!--CRLF--> 
  25:             "or it does not implement IController.",
<!--CRLF--> 
  26:                         reqContext.HttpContext.Request.Path));
<!--CRLF--> 
  27:
<!--CRLF--> 
  28:             if (!typeof(IController).IsAssignableFrom(controllerType))
<!--CRLF--> 
  29:                 throw new ArgumentException(
<!--CRLF--> 
  30:                         string.Format(
<!--CRLF--> 
  31:                             "Type requested is not a controller: {0}",
<!--CRLF--> 
  32:                             controllerType.Name),
<!--CRLF--> 
  33:                             "controllerType");
<!--CRLF--> 
  34:             try
<!--CRLF--> 
  35:             {
<!--CRLF--> 
  36:                 //controller = MvcUnityContainer.Container.Resolve(controllerType)
<!--CRLF--> 
  37:                 //                as IController;
<!--CRLF--> 
  38:                 controller = container.Resolve(controllerType) as IController;
<!--CRLF--> 
  39:             }
<!--CRLF--> 
  40:             catch (Exception ex)
<!--CRLF--> 
  41:             {
<!--CRLF--> 
  42:                 throw new InvalidOperationException(String.Format(
<!--CRLF--> 
  43:                                         "Error resolving controller {0}",
<!--CRLF--> 
  44:                                         controllerType.Name), ex);
<!--CRLF--> 
  45:             }
<!--CRLF--> 
  46:             return controller;
<!--CRLF--> 
  47:         }
<!--CRLF--> 
  48:
<!--CRLF--> 
  49:     }
<!--CRLF--> 
  50:     public class HttpContextLifetimeManager<t> : LifetimeManager, IDisposable</t>
<!--CRLF--> 
  51:     {
<!--CRLF--> 
  52:         public override object GetValue()
<!--CRLF--> 
  53:         {
<!--CRLF--> 
  54:             return HttpContext.Current.Items[typeof(T).AssemblyQualifiedName];
<!--CRLF--> 
  55:         }
<!--CRLF--> 
  56:         public override void RemoveValue()
<!--CRLF--> 
  57:         {
<!--CRLF--> 
  58:             HttpContext.Current.Items.Remove(typeof(T).AssemblyQualifiedName);
<!--CRLF--> 
  59:         }
<!--CRLF--> 
  60:         public override void SetValue(object newValue)
<!--CRLF--> 
  61:         {
<!--CRLF--> 
  62:             HttpContext.Current.Items[typeof(T).AssemblyQualifiedName] = newValue;
<!--CRLF--> 
  63:         }
<!--CRLF--> 
  64:         public void Dispose()
<!--CRLF--> 
  65:         {
<!--CRLF--> 
  66:             RemoveValue();
<!--CRLF--> 
  67:         }
<!--CRLF--> 
  68:     }
<!--CRLF--> 
  69: }
<!--CRLF-->

配置Unity:
