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。

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Text;
 5 using System.Threading.Tasks;
 6 
 7 using Happy.OSGI;
 8 
 9 namespace Happy.Web.Mvc
10 {
11     public sealed class MvcBundleContainerPlug : IBundleContainerPlug
12     {
13         void IBundleContainerPlug.Start(BundleContext context)
14         {
15             MvcBundleContainerExtensions
16                 .Current
17                 .OSGIControllerTypeCache
18                 .RegistAssembly(context.Bundle.Assembly);
19         }
20 
21         void IBundleContainerPlug.Stop(BundleContext context)
22         {
23             MvcBundleContainerExtensions
24                 .Current
25                 .OSGIControllerTypeCache
26                 .UnRegistAssembly(context.Bundle.Assembly);
27         }
28     }
29 }

关键配置代码

 1 namespace Happy.OSGI.Demo.WebHost
 2 {
 3     // Note: For instructions on enabling IIS6 or IIS7 classic mode,

 5     public class MvcApplication : System.Web.HttpApplication
 6     {
 7         protected void Application_Start()
 8         {
 9             this.Initialize();
10 
11             AreaRegistration.RegisterAllAreas();
12 
13             WebApiConfig.Register(GlobalConfiguration.Configuration);
14             FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
15             RouteConfig.RegisterRoutes(RouteTable.Routes);
16         }
17 
18         private void Initialize()
19         {
20             BundleContainer
21                 .Current
22                 .UseDirectoryAssemblyLoader()
23                 .UseDirectoryAssemblyLoader(@"E:\开发\Happy.OSGI.Demo\Happy.OSGI.Demo.Host\bin\Debug\Bundles")
24                 .IntegrationWithMvc()
25                 .UseUnity()
26                 .RegistCommandHandlerByConvention()
27                 .Start();
28 
29             DependencyResolver.SetResolver(new ServiceLocationDependencyResolver(ServiceLocator.Current));
30         }
31     }
32 }
