dependency-injection

问题 EDIT: using YEOMAN to scaffold my app, I have the following YEOMAN generated provider 'use strict'; angular.module('myApp') .provider('myProvider', function () { // Private variables var salutation = 'Hello'; // Private constructor function Greeter() { this.greet = function () { return salutation; }; } // Public API for configuration this.setSalutation = function (s) { salutation = s; }; // Method for instantiating this.$get = function () { return new Greeter(); }; }); and I'm trying inject

问题 If I have a thread that is started from the main application. In this thread events are generated. Everytime an event is generated an object is created. In that object a dependancy is needed so I want to inject that object. How can I pass this dependancy to the created object? Do I need to pass the depandancy downwards (and let the class that works in the thread know of the dependancy) or is there a nicer way to do this? I'm using Unity btw. 回答1: The safest way is to let each thread build a

问题 This is my scenario: I want all my Activities to inherit from BaseActivity Within the BaseActivity , I want to inject Navigator (it helps me to manage the Fragments backstack and navigate between activities): abstract class BaseActivity : DaggerAppCompatActivity() { @Inject lateinit var navigator: Navigator @Inject lateinit var prefs: SharedPreferences // injected via AppModule.kt, see below. } The Navigator class needs a FragmentManager in its constructor: class Navigator @Inject constructor

问题 I have a Play 2.3 app that I'm migrating to Play 2.4 and I'm working on one of the warnings which is about migrating the plugin's to modules. I'm following this documentation here: https://www.playframework.com/documentation/2.4.x/PluginsToModules I have now a couple of questions in my application that has some Akka actors. So far here is what I did with the plugins: class MyPlugin extends Plugin { // I get the current Application val app = play.api.Play.current // On start of the plugin, I

问题 I'm following along with Play 2.6's Scala documentation and sample code for creating non-blocking actions, and am running into some runtime issues. I have created a new Play application using the Scala template ( sbt new playframework/play-scala-seed.g8 ). The code that the Play documentation suggests should work in a new controller is (this code is taken verbatim from the Play documentation page, with some extra imports from me): // some imports added by me to get the code to compile import

问题 Are there any DI frameworks in the .Net world that is simple and which does not require too much meta-data configuration for eg. using xml etc? A very good example from the Java world would be JBoss Weld. With Weld it is possible to have producer methods (methods that can be marked with custom annotation) that return objects. The objects produced above can be injected where needed. This saves a lot of meta-data configuration. Ofcourse Weld needs an xml too, but it does not mandate extensive

问题 I'm trying to inject spring bean into JSF bean, I'm using Spring 3.1 and JSF 2 (Mojarra 2.1.7) Without a lot of talking my configuration and code and exception listed in the following: StudentService.java: @Scope(proxyMode=ScopedProxyMode.TARGET_CLASS) public class StudentsService extends AbstractMaqraaService { @Override public Set<Class<?>> getTypes() { // TODO Auto-generated method stub return null; } public Student registerStudent(Student student) { return this.store(student); } }

问题 Similar question has been here a few times already but unfortunately I wasn't able to find the help needed in there. I am trying to create a custom extension class in Symfony (3.1). I am following the cookbook [1,2] but no matter what I try, I get the error InvalidArgumentException in YamlFileLoader.php line 404: There is no extension able to load the configuration for "czechnology_tools" (in [path_to_project]\src\Czechnology\ToolsBundle\DependencyInjection/../Resources/config\holidays.yml).

问题 After going through some tutorials on asp.net mvc the repository pattern came up and the example was with one table, the dinners table. Basically the set up was to create an interface and then a concrete class which implemented the interface and program off the interface in the controller class. The Interface has your typical crud methods. Does an interface for each type have to be created if you are going to use this pattern. For instance there was a GetList method with a Dinner type. What
