无法添加第二个AngularJS服务工厂

我尝试向AngularJS模块添加2个服务。一个应该访问我的员工和一个我的产品，但我在两个控制器文件中都获得了一个

未知提供程序：EmployeeServiceProvider，按如下方式检索模块（删除依赖项列表）——

将依赖项添加到此处的
ngResource
，同时在App/Module中声明-

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

您的模块在
ProductController
中的第二次调用中被重新创建，因此覆盖了以前的模块和服务定义。
您是否在index.html中添加了对EmployeeService.js的引用？是的。但是我确实添加了Index.html中的部分。我的代码在家里，但是看起来你是绝对正确的。这位官员甚至有自己的章节“创作与检索”
var coffeewatchServices = angular.module('coffeewatchServices', ['ngResource']);

var employeeServiceUrlPart = "EmployeeService/";
coffeewatchServices.factory('EmployeeService', ['$resource',
    function($resource){
        return $resource('all/', {}, {
            all:     {method:'GET',url:REST_BASEURL+employeeServiceUrlPart+"all", params:{}, isArray:true}
        });
    }]);

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

var productServiceUrlPart = "ProductService/";
coffeewatchServices.factory('ProductService', ['$resource',
    function($resource){
        return $resource('all/', {}, {
            all: {method:'GET',url:REST_BASEURL+productServiceUrlPart+"all", params:{}, isArray:true}
        });
    }]);

coffeewatchControllers.controller('BookingController', ['$scope', 'EmployeeService', 'ProductService',
    function ($scope, EmployeeService, ProductService) {
        $scope.employees = EmployeeService.all();
        $scope.products = ProductService.all();
}]);
