php - Invalid factory registered Zend Framework 2 tutorial and everything seems to be in place -

here's module/blog/config/module.config.php

<?php     return array(         'service_manager' => array(             'invokables' => array(                 'blog\service\postserviceinterface' => 'blog\service\postservice'             )         ),         'controllers' => array(             'factories' => array(                 'blog\controller\list' => 'blog\controller\listcontrollerfactory'             )         ),     'router' => array(         // open configuration possible routes         'routes' => array(             // define new route called "post"             'post' => array(                 // define routes type "zend\mvc\router\http\literal", string                 'type' => 'literal',                 // configure route                 'options' => array(                     // listen "/blog" uri                     'route'    => '/blog',                     // define default controller , action called when route matched                     'defaults' => array(                         'controller' => 'blog\controller\list',                         'action'     => 'index',                     )                 )             )         )     ),     'view_manager' => array(         'template_path_stack' => array(             __dir__ . '/../view',         ),     ) ); 

here's module/blog/src/blog/controller/listcontroller.php

    <?php     namespace blog\controller;      use blog\service\postserviceinterface;     use zend\mvc\controller\abstractactioncontroller;     use zend\view\model\viewmodel;      class listcontroller extends abstractactioncontroller     {         protected $postservice;          public function __construct(postserviceinterface $postservice)         {             $this->postservice = $postservice;         }          public function indexaction()         {             return new viewmodel(array(                 'posts' => $this->postservice->findallposts()             ));         }     } 

here's module/blog/src/blog/factory/listcontrollerfactory.php

    <?php     namespace blog\factory;      use blog\controller\listcontroller;     use zend\servicemanager\factoryinterface;     use zend\servicemanager\servicelocatorinterface;      class listcontrollerfactory implements factoryinterface     {         public function createservice(servicelocatorinterface $servicelocator)         {             $realservicelocator = $servicelocator->getservicelocator();             $postservice = $realservicelocator->get('blog\service\postserviceinterface');             return new listcontroller($postservice);         }     } 

finally, here module/blog/module.php

    <?php     namespace blog;      use zend\modulemanager\feature\configproviderinterface;     use zend\modulemanager\feature\autoloaderproviderinterface;     use codegenerationutils\autoloader\autoloaderinterface;      class module implements configproviderinterface,autoloaderproviderinterface     {         public function getconfig()         {             return include __dir__ . '/config/module.config.php';         }          public function getautoloaderconfig()         {             return array(                 'zend\loader\standardautoloader' => array(                     'namespaces' => array(                         // autoload classes namespace 'blog' '/module/blog/src/blog'                         __namespace__ => __dir__ . '/src/' . __namespace__,                     )                 )             );         }     } 

i getting error:

while attempting create blogcontrollerlist(alias: blog\controller\list) invalid factory registered instance type. 

not sure whats wrong here seems in place.

in config point blog\controller\listcontrollerfactory while file in blog\factory\listcontrollerfactory.

update , work:

'controllers' => array(     'factories' => array(         'blog\controller\list' => 'blog\factory\listcontrollerfactory'     ) )
