OSGI：OSGI集成ASP.NET MVC4.0

OSGI能动态的加载、启动和停止Bundle，之前我实现了和Ioc的集成以动态的注册和取消注册Bundle中公开的服务。今天简单的实现了和MVC的集成以动态的管理Controller。

ASP.NET MVC默认只识别BIN目录下的程序集，当然你可以修改一些配置让他支持其它目录，我采用的策略时重写DefaultControllerFactory+OSGI插件，插件动态管理ControllerType的注册和取消注册，ControllerFactory根据注册的信息获取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);
        }
    }
}

关键配置代码

namespace Happy.OSGI.Demo.WebHost
{
    // Note: For instructions on enabling IIS6 or IIS7 classic mode, 
    // visit http://go.microsoft.com/?LinkId=9394801
    public class MvcApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
            this.Initialize();

            AreaRegistration.RegisterAllAreas();

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

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

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