首先,对不起我的英语。我想在windsor + mvc做一些小事。我阅读了一些教程,并寻找我的问题的任何解决方案,但我还没有发现任何问题。使用:
我想构建一个模块化应用程序(web + domain + db layer),但我仍然会收到错误:
异常详细信息: System.MissingMethodException:无法创建接口实例。
来源错误: 在执行当前Web请求期间生成了未处理的异常。可以使用下面的异常堆栈跟踪来识别有关异常的起源和位置的信息。

我的应用的主要类别或功能(现在所有在同一模块/ dll .web )
public class HomeController : Controller
{
public ActionResult Home(ITestApi test)
{
var result = test.Test();
return View();
}
}
ITestApi界面
namespace Dashboard.Web.Services.Interfaces
{
public interface ITestApi
{
string Test();
}
}
TestApi Class
namespace Dashboard.Web.Services.Implementation
{
public class TestApi : ITestApi
{
public string Test()
{
return "test";
}
}
}
Global.asax中的
private static void BootstrapContainer() {
Container = new WindsorContainer();
Container.Install(FromAssembly.InThisApplication());
// Create the Controller Factory
var castleControllerFactory = new WindsorControllerFactory(Container);
// Add the Controller Factory into the MVC web request pipeline
ControllerBuilder.Current.SetControllerFactory(castleControllerFactory);
}
安装
public class WebInstaller : IWindsorInstaller
{
public void Install(IWindsorContainer container, IConfigurationStore store)
{
container.Register(
Classes.FromThisAssembly()
.BasedOn<IController>()
.LifestyleTransient()
);
container.Register(
Classes.FromThisAssembly()
.BasedOn<ITestApi>()
.LifestyleTransient()
);
}
}
我已经为注册TestApi类尝试了一些不同的方法,但结果始终是相同的。
container.Register(
Classes.FromAssemblyInThisApplication()
.InSameNamespaceAs(typeof(ITestApi))
//.WithServiceDefaultInterfaces()
.WithService.DefaultInterfaces()
.LifestyleTransient()
);
有人可以帮助我吗?
答案 0 :(得分:0)
我不确定,但我认为你只是注册所有使用ITestApi的类而不是他们自己的名字,但你永远不会说当CastleWindsor注入ITestApi时应该使用哪个类
替换
container.Register(
Classes.FromThisAssembly()
.BasedOn<ITestApi>()
.LifestyleTransient()
);
使用C#版本(对不起,只有一个VB.NET代码段)
container.Register(Component.For(Of ITestApi).ImplementedBy(Of TestApi).LifestyleTransient())
