部署到我的服务器时，我的asp.net mvc Web应用程序出现了问题，但是当我通过visual studio运行时却没有。
这是错误
无法创建组件＆＃39; IndustrialRealEstate.Web.Controllers.ZoningController＆＃39;因为它有依赖性来满足。＆＃39;
有问题的依赖是一个名为ZoningService的服务，它基于一个名为IDataService的通用接口。
以下是我正在使用的代码
控制器：
public class ZoningController : BaseController
{
private readonly IDataService<ZoningWrapper> _zoningService;
public ZoningController(IDataService<ZoningWrapper> service)
{
_zoningService = service;
}
//functions
}
HasContext抽象类：
public abstract class HasContext
{
private IREDbContext _ireDbContext;
public IREDbContext IREDbContext
{
get
{
if (_ireDbContext != null)
return _ireDbContext;
_ireDbContext = new IREDbContext();
return _ireDbContext;
}
}
}
IDataService接口
public interface IDataService<T>
{
T Get(string id);
ICollection<T> GetAll();
T Save(T dataWrapper);
bool AlreadyExists(T dataWrapper);
bool HasDependency(string id);
bool Delete(string id);
}
服务：
public class ZoningService : HasContext, IDataService<ZoningWrapper>
{
//Implemented functions from the interface
}
的ServiceInstaller：
public class ServicesInstaller : IWindsorInstaller
{
public void Install(IWindsorContainer container, IConfigurationStore store)
{
container.Register(Component.For<IDataService<ZoningWrapper>>().ImplementedBy<ZoningService>());
}
}
现在，正如我所说，当我通过视觉工作室运行时，它正在100％运行。直到我部署到服务器并且数据没有通过，我才意识到存在问题。阅读日志给出了这个特定的信息，我无法确定问题所在。
如果有任何人有任何见解或方向，他们可以指出我，我会非常感激。
编辑 - 以下是控制器的连接方式
public class ControllersInstaller : IWindsorInstaller
{
public void Install(IWindsorContainer container, IConfigurationStore store)
{
container.Register(Castle.MicroKernel.Registration.Classes.FromThisAssembly()
.BasedOn<BaseController>()
.LifestylePerWebRequest()
.Configure(x => x.Named(x.Implementation.FullName)));
container.Register(Castle.MicroKernel.Registration.Classes.FromThisAssembly()
.BasedOn<Controller>()
.LifestylePerWebRequest()
.Configure(x => x.Named(x.Implementation.FullName)));
}
}

做了类似于WebAPI项目的事情。需要添加以下内容..
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web.Http.Dependencies;
using Castle.MicroKernel;
using Castle.MicroKernel.Lifestyle;
namespace MyProject.DependencyInjection
{
public class WindsorDependencyScope : IDependencyScope
{
private readonly IKernel container;
private readonly IDisposable scope;
public WindsorDependencyScope(IKernel container)
{
this.container = container;
this.scope = container.BeginScope();
}
public object GetService(Type serviceType)
{
return this.container.HasComponent(serviceType) ? this.container.Resolve(serviceType) : null;
}
public IEnumerable<object> GetServices(Type serviceType)
{
return this.container.ResolveAll(serviceType).Cast<object>();
}
public void Dispose()
{
this.scope.Dispose();
}
}
}
...然后添加......
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web.Http.Dependencies;
using Castle.MicroKernel;
namespace MyProject.DependencyInjection
{
internal class WindsorDependencyResolver : System.Web.Http.Dependencies.IDependencyResolver
{
private readonly IKernel container;
public WindsorDependencyResolver(IKernel container)
{
this.container = container;
}
public IDependencyScope BeginScope()
{
return new WindsorDependencyScope(this.container);
}
public object GetService(Type serviceType)
{
return this.container.HasComponent(serviceType) ? this.container.Resolve(serviceType) : null;
}
public IEnumerable<object> GetServices(Type serviceType)
{
return this.container.ResolveAll(serviceType).Cast<object>();
}
public void Dispose() { }
}
}
然后修改global.asax文件......
using System.Web.Http;
using System.Web.Mvc;
using System.Web.Routing;
using Castle.Windsor;
using Castle.Windsor.Installer;
using MyProject.DependencyInjection;
namespace MyProject
{
// Note: For instructions on enabling IIS6 or IIS7 classic mode,
// visit http://go.microsoft.com/?LinkId=9394801
public class WebApiApplication : System.Web.HttpApplication
{
protected void Application_Start()
{
var container = new WindsorContainer();
container.Install(FromAssembly.This());
GlobalConfiguration.Configuration.DependencyResolver = new WindsorDependencyResolver(container.Kernel);
AreaRegistration.RegisterAllAreas();
WebApiConfig.Register(GlobalConfiguration.Configuration);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
}
}
}
我的安装程序示例......
using System.Web.Http;
using Castle.MicroKernel.Registration;
using Castle.MicroKernel.SubSystems.Configuration;
using Castle.Windsor;
namespace MyProject.DependencyInjection
{
public class WindsorWebApiInstaller : IWindsorInstaller
{
public void Install(IWindsorContainer container, IConfigurationStore store)
{
container.Register(
Types.FromThisAssembly().BasedOn<ApiController>().LifestyleScoped()
, Component.For<MyProject.Database.IDataAccessMethods>().ImplementedBy<MyProject.Database.DataAccessMethods>().LifestylePerWebRequest()
);
}
}
}

我会检查您的安装程序是否都在同一个程序集中，并检查container.Install调用是否与您需要涵盖的程序集范围相匹配。例如，初始化程序时，可能无法加载包含服务安装程序的程序集。也许记录安装的内容可以帮助您检查代码是否在程序启动时运行。
Re：调试这类问题：
很难在服务器上确定您的容器缺少什么。如果您可以在可以进行调试的机器上重现问题，我建议您使用Castle Debugging views。
在我看来，更好的是，您可以设置一个测试来检查Castle是否可以解决所有依赖项：
[SetUpFixture]
public class TestIOC
{
public IWindsorContainer Target { get; set; }
[SetUp()]
public void before_all_tests()
{
Target = global::Main.Structure.IOC.Initialize();
}
public class GeneralTests : TestIOC
{
[Test()]
public void should_never_have_a_potentially_misconfigured_component()
{
var host = (IDiagnosticsHost)Target.Kernel.GetSubSystem(SubSystemConstants.DiagnosticsKey);
var diagnostics = host.GetDiagnostic<IPotentiallyMisconfiguredComponentsDiagnostic>();
var misconfiguredHandlers = diagnostics.Inspect();
if (misconfiguredHandlers.Any())
{
var message = new StringBuilder();
var inspector = new DependencyInspector(message);
foreach (IExposeDependencyInfo handler in misconfiguredHandlers)
{
handler.ObtainDependencyDetails(inspector);
}
Console.WriteLine(message.ToString());
}
Assert.AreEqual(0, misconfiguredHandlers.Count());
}
}
}
这直接来自我使用的测试套件：如果您的IOC设置无法解析某些元素，它将写入std输出。在NUnit中，这转化为一个失败的测试，其中包含一些缺失的细节。 global::Main.Structure.IOC.Initialize();调用在设置后返回容器，我也在主代码中使用它。
以下是诊断输出的示例，可帮助您找到缺少的配置：
* Main.Structure.TestIOC + GeneralTests.should_never_have_a_potentially_misconfigured_component
'Main.Configuration.NotificationManagementConfiguration'正在等待 以下依赖项： - 未提供参数'daily_notification_time'。你忘了设置依赖吗？
您甚至可以在程序开始时将代码添加为健全性检查，并尽可能快地记录任何错误。
