calling service $resource from controller

var axiommodule = angular.module("appaxiom", ['ngResource']);
axiommodule.controller("appcontroller", function (axiomservice) {
    var vm = this;
    vm.hello = "hellow angular";
    vm.name = axiomservice.GetStudent();
    var student = { Name: 'new', Age: '34', Semester: '4th' };
    axiomservice.StudentResource().get({ teacherid: 1 },
        function (response)
        {
            alert(response.Name);
        });
    //axiomservice.StudentResource.update({id:1},function (response) {
    //    alert('deleted');
    //});
   // alert(vm.student);
    //.
    //                        then(function (response) {
    //                            alert('');
    //                        });
   
});
axiommodule.service("axiomservice", function ($http,$resource) {
    this.GetStudent = function () {
        return "hello ! world angular you are very cruel";
    };
    this.StudentResource = function () {
        return $resource('api/Student', {id:'@id',teacherid:'@teacherid'});

});



=========================factory way of calling resource===================
var mod = angular.module('appmodf', ['ngResource']);
mod.controller('gridController', function (gridFactory) {
    var vm = this;  
    gridFactory.studentrepo.query(successCallBack,errorCallBack);
    function successCallBack(data)
    {

            vm.students=data;
        }
        function errorCallBack(error)
        {
            vm.error=error;
        }
   
    });

mod.factory('gridFactory', function ($resource) {
    var service = { studentrepo: $resource(' http://localhost:6074/api/Student/:id/:teacherid', { id: '@id', teacherid: '@teacherid' }) };
    return service;
});
