angularjs：无法注入工厂

Question

I have a factory,

var commonFactories = angular.module('commonFactories', []).
factory('acampaign', function () {
    // return {'a' : 1};
    return "hello";
});

and I am injecting it to a module,

angular.module("campaign", ["ngRoute", "ngResource", "commonServices", "commonFactories"]).
// configure campaign module
config(["acampaign", function(acampaign) {

...

}

Angular throws error saying it cannot instantiate campaign module,

Failed to instantiate module campaign due to:
Error: [$injector:unpr] http://errors.angularjs.org/1.3.12/$injector/unpr?p0=acam...

Answer 1

Your acampaign factory is acampaignProvider in the config function. factories and services are essentially sugar syntax for providers. Look at provider in the guide the provider recipe section
