Zend Framework 2 Get Service Manager

When learning Zend Framework, a lot of problems can only look at the source code, in order to deepen their understanding, recording down the usual method:

1 in the Controller

$serviceLocator = $this->getservicelocator ();

2 in the module.php.

namespace ModuleName;

Use zend\mvc\mvcevent;

Class Module
{
Public Function Onbootstrap (mvcevent $e)
{
$serviceLocator = $e->getapplication ()->getservicemanager ();
}

}

3 on the controller plugin
$serviceLocator = $this->getcontroller ()->getservicelocator ();
