dependency-injection

问题 I have experience of developing a web-based application with Scala and Play. Play supports Guice out of the box, so it is very easy to do DI with Play. I'm currently working on a Scala project that is not a web application and it does not use Play. I want to dynamically inject the config object into a few places. How do I do this? If it is necessary to use some library to do DI, what library is good for this purpose? Any sample code? Is it possible to implement this with plain Scala not using

问题 This question already has answers here : What are providers in Angular2? (5 answers) Closed 2 years ago . I really want to know What is providers? what relationship with DI in angular2? app.module.ts @NgModule({ imports: [ BrowserModule, FormsModule, ], declarations: [ test, ], bootstrap: [ AppComponent ], providers: [ userService ] }) export class AppModule { } test.component.ts export class TestComponent implements OnInit, OnDestroy { constructor(public user: userService) } In my

问题 I am converting some lightInject code to .netcore DI In .netcore DI, we have AddSingleton and AddTransient functions for registering the service. In the lightInject, I have RegisterMethod. So I just want to know whether the Register methods registers only singleton instance or multiple when ever we call. 回答1: based on documentation The default behavior in LightInject is to treat all objects as transients unless otherwise specified. So in .Net Core, you would need to register your services as

问题 I have this code: app.js var promptoWeb = angular.module('promptoWeb', ['ngMaterial', 'ngAnimate', 'ngMessages', 'ngAria', 'ui.router', 'ui.sortable', 'ngFileUpload']); (function (app) { app.factory('env', function () { var domain = {domain: "http://localhost:8860/Elton"}; return domain; }); app.config(['$stateProvider', '$urlRouterProvider', '$compileProvider', function ($stateProvider, $urlRouterProvider, $compileProvider) { self = this; $compileProvider.preAssignBindingsEnabled(true);

问题 I have some problem to implement SimpleInjector with my generic Repository. I have an interface IRepository<T> where T : class and an abstract class abstract class Repository<C, T> : IRepository<T> where T : class where C : DbContext which implements the interface. Finally I have my entity repositories which inherit the abstract class. Here's a concret example: public interface IRepository<T> where T : class { IQueryable<T> GetAll(); IQueryable<T> FindBy(Expression<Func<T, bool>> predicate);

问题 I'm trying to mock a call to an outside service in an integration test, the service is used in a grails webflow. The service isn't in flow or conversation scope, but is added via dependency injection see here. I've managed to figure out a way to override a service via replacing it's metaClass using ExpandoMetaClass. The changes only work when the test is ran alone, if another test that uses that same service is ran before this test, the metaClass changes are gone. Part that overrides the

问题 I have a pretty straight forward setup. namespace ObjectNamespace { public class CustomProcessor : ICustomProcessor<myObject> { public CustomProcessorResult Execute(myObject Data) { try { var container = new UnityContainer(); // UnityConfigurationSection section = new UnityConfigurationSection(); var section = (UnityConfigurationSection)ConfigurationManager.GetSection("unity"); // this gives Microsoft.Practices.Unity.Configuration.UnityConfigurationSection section.Containers.Default.Configure

问题 Following on from this question, I now have the following structure: Wolfie.Core - Contains business logic & entities, also contains repository interfaces (eg IUserRepository) Classes that need to access the repository are using constructor injection. Wolfie.Data - References Wolfie.Core and has a UserRepository implementing IUserRepository So I'm happy with this so far. Core doesn't know anything about data implementation and therefore isn't dependent on anything. The stumbling block I get

问题 FB.login() is not working. The FB Popup is not requesting the right permissions. I can clearly see, in the source code that there's a fn handler that uses the right parameters / parameters being set correctly. I'd like to understand why isn't this working ? This is the code I've got so far: http://jsbin.com/IteY/1/ This is where I'm setting the permissions list: facebook.login(function(response) { console.log(response); }, {scope: 'email,user_likes'}); in accordance with the docs ( https:/

问题 I have the following classes and I am trying to implement Dependency Injection into calling a WCF Service in ASP.NET Zero. Interface IUserProxyService implements IApplicationService with CreateUser method. Class UserProxyService implments IUserProxyService with construction injection of IUserRepository and has a CreateUser Method. Interface IUserRepository specifies to implement CreateUser method. Class UserRespository implments IUserRepository with public constructor without parmaters
