AngularJS错误：$injector:unpr 未知提供者

我正在尝试按照文档中工厂方法的示例来构建自己的服务。然而，我认为我做错了什么，因为我一直收到未知提供者的错误。这是我的应用程序代码，包括声明、配置和工厂定义。

我现在已经添加了所有的文件来帮助排除故障

错误的完整详细信息如下，问题似乎出在getSettings上，因为它在查找getSettingsProvider时找不到

这是我目前在我的应用程序中的所有文件

app.JS

//初始化angular模块包括路由依赖项
var app = angular.module("selfservice", ['ngRoute']);
app.config(function ($routeProvider) {
   $routeProvider
       .when('/', {
           templateUrl:"partials/login.html",
           controller:"login"
       });
});
app.factory('getSettings', ['$http', '$q', function($http, $q) {
    return function (type) {
        var q = $q.defer();
        $http.get('models/settings.json').success(function (data) {
            q.resolve(function() {
                var settings = jQuery.parseJSON(data);
                return settings[type];
            });
        });
        return q.promise;
    };
}]);

以下是我在控制器中如何使用此服务

controller.JS

app.controller("globalControl", ['$scope','getSettings', function ($scope,getSettings) {
    var loadSettings = getSettings('global');
    loadSettings.then(function(val) {
        $scope.settings = val;
    });
}]);
app.controller("login", ['$scope', function ($scope) {
    return ""
}]);

directives.js

app.directive('watchResize', function(){
    return {
        restrict: 'M',
        link: function(scope, elem, attr) {
            scope.spacer = (window.innerWidth < 1025) ? '' : 'large-3';
            scope.button = (window.innerWidth < 1025) ? '' : 'large-6';
            angular.element(window).on('resize', function(){
                scope.$apply(function(){
                    scope.spacer = (window.innerWidth < 1025) ? '' : 'large-3';
                    scope.button = (window.innerWidth < 1025) ? '' : 'large-6';
                });
            });
        }
    };
});

如果相关的话，这是HTML

有人可以指点我正确的方向吗？我已经尽力按照文档进行操作，浏览了SO上的大部分相关问题，但更深入一些，对我来说更难理解。这是我第一次创建服务。
