Castle Windsor 项目中快速使用

Castle Windsor 项目中快速使用

新建项目如下：

一个模型类，一个接口，一个实现方法。我的目的很明确就是在UI层通过Castle 调用数据访问层的方法。

添加项目引用

CastleDemo.DataAccess 引用 CastleDemo.Domain

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

安装组件

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

CastleDemo.DataAccess 安装 EntityFramework

CastleDemo.Domain

IRepository:

 public interface IRepository<T>  where T : class
     {
         /// <summary>
         /// 查询
         /// </summary>
         /// <param name="condition">查询条件</param>
         /// <param name="order">排序条件</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("产品");
             Expression<Func<Product, object>> order = m => m.productId;

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

             return View(products);
         }

Web.config里还需在相应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>

在运行代码前，我们还差最后一步，在前面的添加引用的时候WebUI层没有添加对CastleDemo.DataAccess层的引用，那么这个时 候我们需要把CastleDemo.DataAccess层的EntityFramework.dll 和 CastleDemo.DataAccess.dll拷贝到WebUI的BIN里面，但又有个问题来了，那我们每次对 CastleDemo.DataAccess层代码的改动都要重新拷贝，多麻烦啊，解决方法请参考我的另一篇文章VS XCOPY

最后运行看下效果：
