[AngularJS] How to pass Factory to Controller through $routeProvider.when {} statement

Hi Experts

I am using 

.config(function($routeProvider, $locationProvider) { }

I am passing the 

    templateUrl: 'chapter.html',

    controller: 'ChapterController'

but i do not know how to pass factory on which ChapterController is dependent.

I know through resolve attribute, i can pass the factory to ChapterController.

but what is the correct syntax.

Any help will be appreciated.

See the sample below. 

(function(angular) {

  'use strict';

angular.module('ngRouteExample', ['ngRoute'])

.factory('grettingTokenFactory',function() {

 var factory: {};

 factory.getText(){

 return 'Hello world'

 }

 return factory;

})

 .controller('BookController', function($scope, $routeParams) {

     $scope.name = "BookController";

     $scope.params = $routeParams;

 })

 .controller('ChapterController', function($scope, $routeParams, grettingTokenFactory) {

     $scope.name = "ChapterController";

     $scope.params = $routeParams;

     $scope.greetings = grettingTokenFactory.getText();

 })

.config(function($routeProvider, $locationProvider) {

  $routeProvider

   .when('/Book/:bookId', {

    templateUrl: 'book.html',

    controller: 'BookController',

    resolve: {

      // I will cause a 1 second delay

      delay: function($q, $timeout) {

        var delay = $q.defer();

        $timeout(delay.resolve, 1000);

        return delay.promise;

      }

    }

  })

  .when('/Book/:bookId/ch/:chapterId', {

    templateUrl: 'chapter.html',

    controller: 'ChapterController'

    

  });

  // configure html5 to get links working on jsfiddle

  $locationProvider.html5Mode(true);

});

})(window.angular);
