Castle Windsor 項目中快速使用

新建項目如下：

 

一個模型類，一個接口，一個實現方法。我的目的很明確就是在UI層通過Castle 調用數據訪問層的方法。

添加項目引用

CastleDemo.DataAccess 引用 CastleDemo.Domain

CastleDemo.WebUI 引用 CastleDemo.Domain（不需要引用CastleDemo.DataAccess）

安裝組件

CastleDemo.DataAccess和 CastleDemo.Domain 都需安裝 Castle.Core , Castle.Windsor

CastleDemo.DataAccess 安裝 EntityFramework

 

CastleDemo.Domain 

IRepository:

public interface IRepository<T>  where T : class
    {
        /// <summary>
        /// 查詢  
        /// </summary>
        /// <param name="condition">查詢條件</param>
        /// <param name="order">排序條件</param>
        /// <returns></returns>
        IEnumerable<T> Find(Expression<Func<T, bool>> condition, Expression<Func<T, object>> order = null);
    }

Product:

 public class Product
    {
       public string productId { get; set; }

       public string productName { get; set; }
    }

IoCContainer:

internal class IoCContainer
    {
        private static readonly object syncRoot = new object();

        private IoCContainer() { }

        private static IWindsorContainer _Instance;

        public static IWindsorContainer Instance
        {
            get
            {
                lock (syncRoot)
                {
                    if (_Instance == null)
                    {
                        _Instance = new WindsorContainer().Install(Configuration.FromAppConfig());
                    }
                    return _Instance;
                }
            }
        }
    }

Factories：

public class Factories
    {
        public static T Repository<T>() where T : class
        {
            return IoCContainer.Instance.Resolve<T>();
        }
    }

CastleDemo.DataAccess 

BaseRepository：

    public class BaseRepository<T> : IRepository<T> where T : class
    {
        private castledemoContext context = Factories.Repository<castledemoContext>();

        public IEnumerable<T> Find(Expression<Func<T, bool>> condition, Expression<Func<T,object>> order = null)
        {
            if (order == null)
            {
                return context.Set<T>().Where(condition);
            }

            return context.Set<T>().Where(condition).OrderByDescending(order);
        }
    }

IocInstaller：

    public class IoCInstaller : IWindsorInstaller
    {
        public void Install(IWindsorContainer container, IConfigurationStore store)
        {
            container.Register(Component.For<castledemoContext>().LifeStyle.PerWebRequest);

            container.Register(Classes.FromThisAssembly()
             .InNamespace("CastleDemo.DataAccess.RepositoryImpl", true)
             .LifestylePerWebRequest()
             .WithService.AllInterfaces());
        }
    }

CastleDemo.WebUI

HomeController >> Index:

 public ActionResult Index()
        {
            Expression<Func<Product, bool>> condition = m => m.productName.Contains("產品");
            Expression<Func<Product, object>> order = m => m.productId;

            var products = Factories.Repository<IRepository<Product>>().Find( order: order,condition: condition);

            return View(products);
        }

Web.config里還需在相應的地方添加一些配置：

  <configSections>
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
    <section name="castle" type="Castle.Windsor.Configuration.AppDomain.CastleSectionHandler,Castle.Windsor" />
  </configSections>

--分割--
    <httpModules>
      <add name="PerRequestLifestyle" type="Castle.MicroKernel.Lifestyle.PerWebRequestLifestyleModule, Castle.Windsor" />
    </httpModules>

--分割--

  <castle>
    <installers>
      <install type="CastleDemo.DataAccess.IoCInstaller,CastleDemo.DataAccess" />
    </installers>
  </castle>

在運行代碼前，我們還差最后一步，在前面的添加引用的時候WebUI層沒有添加對CastleDemo.DataAccess層的引用，那么這個時候我們需要把CastleDemo.DataAccess層的EntityFramework.dll 和 CastleDemo.DataAccess.dll拷貝到WebUI的BIN里面，但又有個問題來了，那我們每次對CastleDemo.DataAccess層代碼的改動都要重新拷貝，多麻煩啊，解決方法請參考我的另一篇文章 VS XCOPY

最后運行看下效果：
