Javascript 为什么我会得到'；工厂未定义'；angularjs中的错误？

你能帮我找出这段代码的错误吗，它说“foodFactory未定义”。我还在学习angularjs，所以可能会有错误，但我正在尝试使用routes+factory

var foodApp = angular.module("foodApp", ["ngRoute"]);

        foodApp.config(function($routeProvider)
        {

            $routeProvider
                    .when('/',
                    {
                       controller: 'foodController',
                       templateUrl: '/routes/view1.html'
                    })
                    .when('/view2',
                    {
                       controller: 'foodController',
                       templateUrl: '/routes/view2.html'
                    })
                    .when('/view3',
                    {
                       controller: 'foodController2',
                       templateUrl: '/routes/view3.html'
                    })
                    .otherwise
                    ({ redirectTo: '/' });

        });

        foodApp.factory("foodFactory", function()
        {
            var foods = [
                {name: "Bread"},
                {name: "Cheese"},
                {name: "Blackberries"}
            ];

            var factory = {};

            factory.getFoods = function ()
            {
                return foods;
            };

            return factory;

        });

        var controllers = {};

        controllers.foodController = function($scope)
        {
            $scope.foods = foodFactory.getFoods();
            $scope.foods2 = foodFactory.getFoods();
        };

        controllers.foodController2 = function($scope)
        {
            $scope.foods = foodFactory.getFoods();
        };

        foodApp.controller(controllers);

view1.html、view2.html和view3.html-都很好，路由也可以工作，但它不能从工厂返回食物数组。

非常感谢，就这样！

    controllers.foodController = function($scope,foodFactory) // you need to inject foodFactory
    {
        $scope.foods = foodFactory.getFoods();
        $scope.foods2 = foodFactory.getFoods();
    };

    controllers.foodController2 = function($scope,foodFactory) // you need to inject foodFactory
    {
        $scope.foods = foodFactory.getFoods();
    };
