OSGI：OSGI集成ASP.NET MVC4.0

OSGI能動態的加載、啟動和停止Bundle，之前我實現了和Ioc的集成以動態的注冊和取消注冊Bundle中公開的服務。今天簡單的實現了和MVC的集成以動態的管理Controller。

ASP.NET MVC默認只識別BIN目錄下的程序集，當然你可以修改一些配置讓他支持其它目錄，我采用的策略時重寫DefaultControllerFactory+OSGI插件，插件動態管理ControllerType的注冊和取消注冊，ControllerFactory根據注冊的信息獲取ControllerType。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

using Happy.OSGI;

namespace Happy.Web.Mvc
{
    public sealed class MvcBundleContainerPlug : IBundleContainerPlug
    {
        void IBundleContainerPlug.Start(BundleContext context)
        {
            MvcBundleContainerExtensions
                .Current
                .OSGIControllerTypeCache
                .RegistAssembly(context.Bundle.Assembly);
        }

        void IBundleContainerPlug.Stop(BundleContext context)
        {
            MvcBundleContainerExtensions
                .Current
                .OSGIControllerTypeCache
                .UnRegistAssembly(context.Bundle.Assembly);
        }
    }
}

            WebApiConfig.Register(GlobalConfiguration.Configuration);
            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            RouteConfig.RegisterRoutes(RouteTable.Routes);
        }

        private void Initialize()
        {
            BundleContainer
                .Current
                .UseDirectoryAssemblyLoader()
                .UseDirectoryAssemblyLoader(@"E:\開發\Happy.OSGI.Demo\Happy.OSGI.Demo.Host\bin\Debug\Bundles")
                .IntegrationWithMvc()
                .UseUnity()
                .RegistCommandHandlerByConvention()
                .Start();

            DependencyResolver.SetResolver(new ServiceLocationDependencyResolver(ServiceLocator.Current));
        }
    }
}
