类型的未处理的异常'System.StackOverflowException'发生在System.Core.dll [英] An unhandled exception of type 'System.StackOverflowException' occurred in System.Core.dll
问题描述
在我的Asp.net MVC项目
我有一个初始化单位容器bootsrapper。
我不知道为什么，但我得到
类型'System.StackOverflowException的未处理的异常出现在System.Core.dll
我已经翻了一番检查并登记在我的初始化只是做了。
所有的依赖关系在构建函数仅注射。
什么可能造成的？
保护无效的Application_Start（）

解决方案如果没有提供code，我想这是由于循环依赖。
另一个可能的原因是，你在你的构造函数中的一个不正确的循环。作为一个例子，一类需要的B的实例，以解决; B级要求C级的实例来加以解决和C类需要一个实例来加以解决。这导致在一个无限循环
大众A级
{
大众A（B B）
{
}
}大众B级
{
大众B（C C）
{
}
}公共C类
{
公众B（A一）
{
}
}In my Asp.net MVC project
I have a bootsrapper that initialize a unity-container.
I don't know why, but I get
An unhandled exception of type 'System.StackOverflowException' occurred in System.Core.dll
I have doubled checked and registration is done only in my initializer.
All dependencies are injected in the ctors only.
What could have caused this?
protected void Application_Start() { AreaRegistration.RegisterAllAreas(); WebApiConfig.Register(GlobalConfiguration.Configuration); FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters); RouteConfig.RegisterRoutes(RouteTable.Routes); Initializer.Initialize(); BundleConfig.RegisterBundles(BundleTable.Bundles); }It fails after
BundleConfig.RegisterBundles(BundleTable.Bundles);public static class Initializer { private static bool isInitialize; private static readonly object LockObj = new object(); private static IUnityContainer defaultContainer = new UnityContainer(); static Initializer() { Initialize(); } public static void Initialize() { if (isInitialize) return; lock (LockObj) { IUnityContainer container = defaultContainer; //registering Unity for MVC DependencyResolver.SetResolver(new UnityDependencyResolver(container)); //registering Unity for web API // GlobalConfiguration.Configuration.DependencyResolver = new Unity.WebApi.UnityDependencyResolver(container); #region managers container.RegisterType<ISettingsManager, SettingsManager>(); container.RegisterType<IMamDataManager, MamDataManager>(); container.RegisterType<IAppsDataManager, AppsDataManager>(); #endregion #region Dals container.RegisterType<IDal<ClientService.DAL.EntityFramework.App>, AppsDal>(); #endregion Dals #region cache container.RegisterType<ICache<string, ClientService.DAL.EntityFramework.Group>, GroupsCache>(new ContainerControlledLifetimeManager()); container.RegisterType<ICache<string, ClientService.DAL.EntityFramework.App>, AppsCache>(new ContainerControlledLifetimeManager()); container.RegisterType<ICache<string, SettingsServiceData>, SettingsServiceDataCache>(new ContainerControlledLifetimeManager()); #endregion cache #region Pollers container.RegisterType<IPoller<ClientService.DAL.EntityFramework.Group>, GroupsPoller>(new ContainerControlledLifetimeManager()); container.RegisterType<IPoller<ClientService.DAL.EntityFramework.App>, AppsPoller>(new ContainerControlledLifetimeManager()); container.RegisterType<IPoller<SettingsServiceData>, SettingsPoller>(new ContainerControlledLifetimeManager()); #endregion Pollers container.RegisterType<IDefaultConfigurationGroupSingleton, DefaultConfigurationGroupSingleton>(new ContainerControlledLifetimeManager()); container.RegisterType<IApplicationLogger, Log4NetLogger>(); if (!isInitialize) { isInitialize = true; } } } }
解决方案Without providing code, I guess this is due to a circular dependency. Another possible reason is that you have an improper loop in one of your constructors.
As an example, A class requires an instance of B to be resolved; B class requires an instance of C class to be resolved and C class needs an instance of A to be resolved. This results in an infinite loop:
public class A { public A(B b) { } } public class B { public B(C c) { } } public class C { public B(A a) { } }
