路线没有调用动作

I'm new to Zend-Framework3.

And migrating my ZF2 application to ZF3.

[:/action] is not calling the Actions in the controller. Do we have to manually write all actions which are defined in the controller as a route?

Here is router from my module.config.php

'router' => array(
    'routes' => array(
        'user' => array(
            'type' => 'segment',
            'options' => array(
                'route' => '/user[/:action][/:id]',
                'constraints' => array(
                    'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
                    'id' => '[0-9]+'
                ),
                'defaults' => array(
                    'controller' => Controller\UserController::class,
                    'action' => 'login'
                )
            )
        ),
    )
)

When I try to call /user/register action. It generates 404 error.

Where am I wrong? Or do I have to register all actions manually?
