AngularJS,解析和未知提供者

.when('/foos',{
templateUrl: 'views/foos.html',controller: 'FoosCtrl',resolve: {
    foo_list: ['$q','$route','$timeout','$location','Foos',function($q,$route,$timeout,$location,Foos) {
        // postpone the execution
        var deferred_foo = $q.defer()

        Foos.getFoos({token:session_uid},successCb)

        function successCb(list) {
            if(list['status'] === 200) {
                deferred_foo.resolve(list)
            }
            else {
                alert('Crashcrashcrash')
                deferred_foo.reject("Something just wasn't right")
                //$location.path('maintenance')
            }
        }
        return deferred_foo.promise
        }]
    }
})
.when('/r/:type/:bar_id',{
    templateUrl: 'views/bar.html',controller: 'BarsCtrl',resolve: {
        bar: ['$q','Bars',Bars) {
            // postpone the execution
            var deferred = $q.defer()

            Bars.getBar({type: bar_type},successCb)    

            function successCb(result) {
                if(result['status'] === 200) {
                    deferred.resolve(result)    
                }
                else {
                    alert('Crashcrashcrash')
                    deferred.reject("Something just wasn't right")
                    $location.path('foos')
                }

                return deferred.promise
                }]
            }
        })

然后我有两个控制器工作这样：

App.controller('FoosCtrl',['$scope','foo_list',function($scope,Foos,foo_list) {...}

 App.controller('BarsCtrl','$routeParams','bar','sharedService',$routeParams,Bars,bar,sharedService) {...}

有人可以解释为什么Bar工作，但Foo给我错误：未知的提供者：foo_listProvider< - foo_list？我试着用不同的名称替换foo_list，如果camelCasing做了一些，但没有帮助。
