Question

我一直在努力让Castle Windsor将我的数据库上下文注入我的控制器我一直在关注Castle Windsor的教程website

我的代码如下
的引导程序

internal class IOCContainerBootstrap
    {
        private static IWindsorContainer container;
        public static void Configure()
        {

            container = new WindsorContainer()
                .Install(FromAssembly.This());

            var controllerFactory = new GravityClimbingControllerFactory(container.Kernel);

            ControllerBuilder.Current.SetControllerFactory(controllerFactory);

        }

        #region IDisposable Members

        public static void Dispose()
        {
            container.Dispose();
        }

        #endregion
    }

安装程序

public class ControllersInstaller : IWindsorInstaller
    {
        public void Install(IWindsorContainer container, IConfigurationStore store)
        {
            container.Register(Classes.FromThisAssembly()
                                .BasedOn<IController>()
                                .LifestyleTransient());

            container.Register(Component.For<DbContext>().ImplementedBy<GravityClimbingEntities>());
        }
    }

    public class APIInstaller : IWindsorInstaller
    {
        public void Install(IWindsorContainer container, IConfigurationStore store)
        {
            container.Register(Classes
                .FromThisAssembly()
                .BasedOn<IHttpController>()
                .ConfigureFor<ApiController>(c => { c.PropertiesIgnore(pi => false); })
                .LifestyleTransient());
        }
    }

最后 我的API控制器

public class ArticalsController : ApiController
    {
        private readonly DbContext _context;
        private readonly Db.Repositories.ArticalRepository repository;
        public ArticalsController(DbContext context)
        {
            _context = context;
            repository = new Db.Repositories.ArticalRepository(context);
        }

        [HttpGet]
        public string HelloWorld()
        {
            return "Hello.world";
        }
    }

当我调试时，我没有得到任何错误，它说它可以解决依赖

Debugger Information

但是当我尝试调用API控制器时，我收到以下错误消息

{
    "Message" : "An error has occurred.",
    "ExceptionMessage" : "Type 'ArticalsController' does not have a default constructor",
    "ExceptionType" : "System.ArgumentException"
}

有什么傻事我做错了，我看不到？

Answer 1

对于面临同样问题的人，我发现了这个问题。

Castle Windsor不知道IHTTPControler（APIController的基础）所以我需要创建一个IHttpControllerActivator并将其附加到GlobalConfiguration.Configuration.Services

我找到了此链接以启用此here
