因此，在普通的旧Angular中，您将像这样注入一个Factory：

(function(angular){
    "use strict";

    var app = angular.module('app', []);
    app.factory('MyFactory', ['$http', function($http) {
    ....
    });
}());

现在使用Typescript，我试图这样使用 $inject :

module Services {
    export class MyFactory {
        static $inject = ['$http'];
        constructor(private $http: ng.IHttpService) {
        }
    }
}

var app = angular.module('app', []);

app.factory('MyFactory', Services.MyFactory) //<-- This does not work, never is instantiated.

app.factory('MyFactory', ['$http', Services.MyFactory]); //<-- No deal, it has constructor dependencies

// Seems you have to do this
app.factory('MyFactory', ['$http', ($http) => new Services.MyFactory($http)]);

使用Typescript在Angular中注入工厂的正确方法是什么？
