如何在Laravel 4中为crud控制器添加新功能？

I'm using Resourceful controller which there are default functions such as index, create, store, show, edit, update and destroy. My question is that how can I add my own function to that controller? For instance I add a function in that controller like this:

class Account extends \Eloquent {
.
.
.
        /**
         * Attempt login.
         * GET /accounts/login
         *
         * @return Response
         */
        public function login()
        {
            //
            echo "You are in login page";
        }

But it seems not work when i enter that url: account/login. This is my route file:

Route::resource('account', 'AccountsController');

You need to add a separate route for it, and the route needs to come before Laravel generates the routes for the resource controller.

Route::get('account/login', 'AccountsController@login');
Route::resource('account', 'AccountsController');
