rails 3 beta : named route not work

when set a named route in config/routes.rb

G0::Application.routes.draw do |map|
resources :users match 'my/login' => 'user#login'

.....

end

use:rake routes ,there was show route is there:

GET /my/login {:controller=>"user", :action=>"login
"}

but when launch server, go to http://localhost:3000/my/login
it will tell you :
No route matches "/my/login"

then I use function test in users_controller_test.rb

1) Error: test_should_route_to_user_login(UsersControllerTest):
ActionController::RoutingError: No route matches "/my/login"
