dependency-injection

问题 I'am trying to inject the application value when starting the play server in order to display something if the app in prod mode and something else if it is in dev mode, I created the module file that will inject eagerly the class: class startModule extends AbstractModule { @Override() override def configure(): Unit = { bind(classOf[StartApplication]).asEagerSingleton() } also I added in the conf file, and my start application code is : @Singleton class StartApplication @Inject() (lifecycle:

问题 I have following situation. There is POJO which has autowired implementation of an interface, using some spring magic as shown bellow. However this dependency doesn't get resolved if creation of channels is managed via spring bean. It only works if POJO factory creates channels. Example bellow. @Controller public class Test{ @RequestMapping(value = "/load", method = RequestMethod.GET) public @ResponseBody String testConfiguration() { // this is pojo and here it works, channels within have

问题 Edit after digging into the symfony code, particularly the ControllerResolver, it seems what im trying to do actually isnt possible unless i subclass/implement ControllerResolverInterface myself. this is the following code which instantiates the controller passed from the route: protected function createController($controller) { if (false === strpos($controller, '::')) { throw new \InvalidArgumentException(sprintf('Unable to find controller "%s".', $controller)); } list($class, $method) =

问题 I've been having trouble using custom directives for my web app. When I pull up the JS console in Chrome, I get this Failed to instantiate module w2l-direc due to: {1} . It seems that there's something wrong with the code I wrote in my module. I'm relatively new to angular so any feed back in regards to the following code would be appreciated (function() { var app = angular.module('w2l-directives', ['ui.bootstrap', 'ngRoute']); app.directive('gamesCol',['$http', function($http){ return {

问题 Hi quick question about injecting an alternative data-source during integration testing of an (EJB 3.0) EJB through its raw POJO API using junit. I have been converting raw POJO services to EJB3 session beans. To do so has really just meant annotating the POJOs directly. The services are also accompanied by existing junit integration tests (that check the result of methods that query a real test database). Several of these services require a direct java.sql.Connection and so I intend to

问题 I have a Visual Studio 2017 solution with 3 projects. One class library that has DAL (.NET Standart 2.0), one AP.NET MVC Application (.NET Core 2.0) and the third Console Application (.NET Framework 4.6.1). I have referenced DAL in both of the projects. It has implemented Unit of Work pattern and uses Entity Framework Core. In ASP.NET MVC project I have configured to get context with Dependency Injection as follows services.AddDbContext<ApplicationDbContext>(options => { options.UseSqlServer

问题 I have a table to display some products in my products list component. There is a moderate amount of data, so I've added in a resolver to not land the user on the page until the data is loaded. Right now, my resolver injects my products service, which has its own methods to load the data from my backend and save the products in an array inside the service. So my resolver injects this service, calls the load products function to prefetch the data and then the component loads. The question is

问题 My classes (let call them X and Y ) both implementing Parser interface do (relatively) CPU intensive operations to build parsers for certain syntaxes (different syntaxes for X and Y ). Now I want to inject (with Guice) dependencies of both X and Y into constructor of an (upper level) parser P . Both arguments of P should be of the type Parser : class P implements Parser { @Inject public P(Parser x, Parser y) { // ... } } How can I make Guice to differentiate which of the two arguments of P

问题 I'm trying to create a webservice that gives some results taken through hibernate from the database. @Path("/book") public class BookService { @Inject private dbController db; @GET @Produces(MediaType.TEXT_PLAIN) public String getBookTitle() { return "H2G2"; } @GET @Path("/users") @Produces(MediaType.APPLICATION_JSON) public Response getUsers(){ List<UserEntity> users = db.getUsers(); return Response.ok(users,MediaType.APPLICATION_JSON).build(); } } the db variable whenever I call http:/
