MVC中使用Castle.Windsor

我在MVC中使用Castle.Windsor是这样用的。

首先在UI层安装Install Castle.Windsor

在App_Start中增加一个类WindsorActivator，用于注册和销毁Containter。注意，这里是在PreApplicationStartMethod中注册的，是在ApplicationShutdownMethod中销毁的。

using Castle.Windsor;
using Castle.Windsor.Installer;
using System;
using WebActivatorEx;

[assembly: PreApplicationStartMethod(typeof(TaskManagement.UI.App_Start.WindsorActivator), "PreStart")]
[assembly: ApplicationShutdownMethodAttribute(typeof(TaskManagement.UI.App_Start.WindsorActivator), "Shutdown")]

namespace TaskManagement.UI.App_Start
{
    public static class WindsorActivator
    {
        public static IWindsorContainer Container;

        public static void PreStart()
        {
            //将这个Assembly中所有实现IWindsorInstaller接口的类都注册
            Container = new WindsorContainer().Install(FromAssembly.This());
        }
        
        public static void Shutdown()
        {
            if (Container != null)
                Container.Dispose();
        }
    }
}

新建一个Installers文件夹，在该文件夹中分别添加多个Installer文件，用于注册DA、Service、Infrastructure层的内容，举例ServiceInstaller.cs文件：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Castle.MicroKernel.Registration;
using Castle.MicroKernel.SubSystems.Configuration;
using Castle.Windsor;
using TaskManagement.Service.Implementation;

namespace TaskManagement.UI.Installers
{
    public class ServiceInstaller : IWindsorInstaller
    {
        public void Install(IWindsorContainer container, IConfigurationStore store)
        {
            //container.Register(Classes.FromThisAssembly()
            //    .IncludeNonPublicTypes()
            //    .BasedOn<ITransient>()
            //    .WithService.DefaultInterfaces()
            //    .LifestyleTransient());

            container.Register(Classes.FromAssemblyNamed("TaskManagement.Service")
                //.IncludeNonPublicTypes()
                .BasedOn<BaseService>()
                .WithService
                .DefaultInterfaces()    //使用默认的I+ServiceName的方式来取Service
                .LifestylePerWebRequest());
            //.LifestyleTransient());
        }
    }
}

其中ControllerInstaller比较特殊：

　　

using System.Web.Mvc;
using Castle.MicroKernel.Registration;
using Castle.MicroKernel.SubSystems.Configuration;
using Castle.Windsor;

namespace TaskManagement.UI.Installers
{
    using Plumbing;

    public class ControllersInstaller : IWindsorInstaller
    {
        public void Install(IWindsorContainer container, IConfigurationStore store)
        {
            //container.Register(
            //    Classes.
            //        FromThisAssembly().
            //        BasedOn<IController>().
            //        If(c => c.Name.EndsWith("Controller")).
            //        LifestyleTransient());

            //ControllerBuilder.Current.SetControllerFactory(new WindsorControllerFactory(container));

            container.Register(Classes.FromThisAssembly().
                    BasedOn<IController>().
                    If(c => c.Name.EndsWith("Controller"))
                    .LifestyleTransient());

            container.Register(Classes.FromThisAssembly()
                .BasedOn<Controller>()
                .LifestyleTransient()
                );
            //设置指定的Controller的工厂，以替代系统默认的工厂
            ControllerBuilder.Current.SetControllerFactory(new WindsorControllerFactory(container));
        }
    }
}

需要额外的一个工厂类来取代默认的DefaultControllerFactory：

using System;
using System.Web;
using System.Web.Mvc;
using System.Web.Routing;
using Castle.Windsor;

namespace TaskManagement.UI.Plumbing
{
    public class WindsorControllerFactory : DefaultControllerFactory
    {
        readonly IWindsorContainer container;

        public WindsorControllerFactory(IWindsorContainer container)
        {
            this.container = container;
        }

        protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType)
        {            
            if (controllerType != null && container.Kernel.HasComponent(controllerType))
                return (IController)container.Resolve(controllerType);

            return base.GetControllerInstance(requestContext, controllerType);
        }

        public override void ReleaseController(IController controller)
        {
            container.Release(controller);
        }
    }
}

使用：

1、属性注册

public class RoleS : BaseService, IRoleS
    {
        public IRoleR _IRoleR { get; set; }
        public IViewR _IViewR { get; set; }
        public IViewActionR _IViewActionR { get; set; }

直接使用即可，注意接口要申明为Public的。

2、构造函数注册。可能在测试、外部调用、Windows服务等情况下用到。

public class ChangeLogS : BaseService, IChangeLogS
    {
        public IChangeLogR _IChangeLogR { get; set; }
        public ChangeLogS(IChangeLogR iChangeLogR)
        {
            _IChangeLogR = iChangeLogR;
        }

3、UI层的Help 类中使用

var _IDepartmentR = WindsorActivator.Container.Kernel.Resolve<IDepartmentR>();
