Suppose I have a class MyClass which can be instantiated either with String or it have predefined static instances inside a class. Something like this: public class MyClass { public final static MyClass A = new MyClass("A"); public final static MyClass B = new MyClass("B"); public final static MyClass C = new MyClass("C"); ... public MyClass(String name) { ... } } Is it possible to create an ArrayList<MyClass> bean in Spring config somehow? Something like <bean id="sequence" class="...ArrayList"> <member class="...MyClass" value="A"/> <member ... /> .... </bean> UPDATE 1 Is it possible to

I am struggling with this problem of dependency injection using untiy . I have implemented according to this link https://www.asp.net/web-api/overview/advanced/dependency-injection But got this error: { "Message": "An error has occurred.", "ExceptionMessage": "An error occurred when trying to create a controller of type 'WebAPIController'. Make sure that the controller has a parameterless public constructor.", "ExceptionType": "System.InvalidOperationException", "StackTrace": " at System.Web.Http.Dispatcher.DefaultHttpControllerActivator.Create(HttpRequestMessage request,

I have an asp.net-mvc website and i am using ninject for IOC and nhibernate for my ORM mapping Here is my IOC binding code: internal class ServiceModule : NinjectModule { public override void Load() { Bind(typeof(IIntKeyedRepository<>)).To(typeof(Repository<>)).InRequestScope(); } } and here is an example of how I am doing IOC into my controller code: public FAQController(IIntKeyedRepository<FAQ> faqRepository, IUnitOfWork unitOfWork) { _faqRepository = faqRepository; _unitOfWork = unitOfWork; } The issue is that up until now, each controller had a single table that it was pointing to so i

EDIT: I forgot to move the kernel into a non-generic parent class here and supply a virtual method to access it. I do realize that the example below, as is, would create a plethora of kernel instances. I just learned how to do injection this past week and here's how I've got things set up currently: using Ninject; using System.Reflection; namespace Infrastructure { public static class Inject<T> { static bool b = Bootstrap(); static IKernel kernel; static bool Bootstrap() { kernel = new StandardKernel(); kernel.Load(Assembly.GetExecutingAssembly()); return true; } public static T New() { return

I am using windsor castle as my IoC container, and has run in to a bit of a problem. This is best explained in code, so I´ll give it a try. I have a factory class, that should provide me with implementations of a certain interface: public interface IObjectCreatorFactory { IObjectCreator GetObjectCreator(Type objectType); } public interface IObjectCreator { T CreateObject<T>(IDataRow data); bool SupportsType(Type type); } Implementation of the factory class could look like this, though I am not sure this is the way to go: public interface ObjectCreatorFactory:IObjectCreatorFactory { IEnumerable

I have a scenario where I need a lower layer to be controlled by an upper layer much like a puppet master pulling on strings. The lower layer also will call back to the upper layer as some internal events are generated from time to time. I am using SimpleInjector, I inject the ILower in to the Upper constructor. I cannot inject the Upper in to the Lower as it would cause a circular reference. Instead I have a register callback function to link the two layers. However, I have to scatter my code with null checks. Are there any nicer ways or different architectures to achieve this linking of

I wrote my CustomLifetimeManager like this: public class CustomLifetimeManager <T> : LifetimeManager { private readonly string _arg; public CustomLifetimeManager(string arg) { _arg = arg; } } Now, it works easy configuring the container programmatically, but how add it in configuration file like the following? <type type="myTime" mapTo="myImpl"> <lifetime type="CustomLifetimeManager"/> </type> You need to add a second class: A TypeConverter. This class is responsible for taking a string and turning it into whatever type you want. Once you implement it, you can then do something like this in
