在MVC中设置Castle Windsor

Question

我正试图第一次设置Castle Windsor,我遇到了一些问题.我的解决方案中有三个项目:

• 域
• DAL
• 卷筒纸

这些服务位于DAL.他们都继承自IService.(UserService实现IUserService,IUserService实现IService).Web应用程序是MVC 5应用程序.所有控制器都继承自BaseController.

我用这篇文章来帮我设置Windsor,但我一直得到例外:

Castle.Windsor.dll中出现"Castle.MicroKernel.ComponentNotFoundException"类型的例外但未在用户代码中处理

附加信息:找不到支持Solution.Web.Controllers.HomeController服务的组件

奇怪的是控制器的路径是正确的.

以下是我的配置代码:

public class WindsorControllerFactory : DefaultControllerFactory
{
  private readonly IKernel kernel;

  public WindsorControllerFactory(IKernel kernel)
  {
    this.kernel = kernel;
  }

  public override void ReleaseController(IController controller)
  {
    kernel.ReleaseComponent(controller);
  }

  protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType)
  {
    if (controllerType == null)
    {
      throw new HttpException(404, string.Format("The controller for path '{0}' could not be found.", requestContext.HttpContext.Request.Path));
    }
    return (IController)kernel.Resolve(controllerType);
  }
}

public class ControllersInstaller : IWindsorInstaller
{
    public void Install(IWindsorContainer container, IConfigurationStore store)
    {
        container.Register(
          Classes.FromThisAssembly()
          .BasedOn(typeof(BaseController))
          .LifestyleTransient());
    }
}

public class ServiceInstaller : IWindsorInstaller
{
    public void Install(IWindsorContainer container, IConfigurationStore store)
    {
        container.Register(Types.FromAssemblyContaining(typeof(IService).GetType())
            .BasedOn<IService>().WithService.FromInterface()
            .LifestyleTransient()
        );
    }
}

在Global.asax中:

public class MvcApplication : System.Web.HttpApplication
{

    private static IWindsorContainer container;

    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();

        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);

        // Setup Castle.Windsor IOC
        MvcApplication.BootstrapContainer();
    }
    protected void Application_End()
    {
        container.Dispose();
    }

    private static void BootstrapContainer()
    {
        container = new WindsorContainer().Install(FromAssembly.This());
        container.Install(FromAssembly.Containing(typeof(IService).GetType()));
        var controllerFactory = new WindsorControllerFactory(container.Kernel);
        ControllerBuilder.Current.SetControllerFactory(controllerFactory);
    }
}

非常感谢任何正确方向的帮助或指导!

Answer 1

我假设它在这里爆炸:

return (IController)kernel.Resolve(controllerType);

你要求城堡用英语做的是"给我实现由controllerType定义的服务的组件".

问题出在您的控制器注册中.

container.Register(
      Types.FromThisAssembly()
      .BasedOn(typeof(BaseController))
      .WithServices(typeof(BaseController))
      .LifestyleTransient());

在这个块中,您告诉castle注册实现BaseController的所有类型,并且它们公开的服务也是BaseController.

因此,Castle正在寻找一个满足服务HomeController的组件,并且无法找到任何东西,因为您获得的唯一服务是BaseController.

长话短说,如果你删除

.WithServices(typeof(BaseController))

Castle将假设您的每个控制器都是一项服务,然后您可以按照您想要的方式请求实现控制器的组件.

作为单独的注释,为了清楚起见,我将Types.FromThisAssembly()更改为Classes.FromThisAssembly(),因为您只查找类将扫描的类,而不是stucts/classes/interfaces等.

我做到了.显然问题是我的服务没有注册.我更改了ServiceInstaller和Global.asax中的注册.

public class ServiceInstaller : IWindsorInstaller
{
    public void Install(IWindsorContainer container, IConfigurationStore store)
    {
        container.Register(Classes.FromAssemblyContaining<BaseService>()
            .BasedOn(typeof(IService))
            .WithService.AllInterfaces()
            .LifestyleTransient());            
    }
}

private static void BootstrapContainer()
{
    container = new WindsorContainer();
    container.Install(new ServiceInstaller());
    container.Install(new ControllersInstaller());

    var controllerFactory = new WindsorControllerFactory(container.Kernel);
    ControllerBuilder.Current.SetControllerFactory(controllerFactory);
}
