无法在控制器中找到包含的类。 Zend框架2

Question

此外，我开始学习zend框架2.使用composel安装skillet应用程序。一切顺利，直到我没有开始阅读那一章http://framework.zend.com/manual/2.3/en/user-guide/forms-and-actions.html 部分我尝试在函数addAction（）的控制器/src/Album/controller/AlbumController.php中创建新的类对象。

我的PHP错误： http://i63.fastpic.ru/big/2014/1201/93/9684e5bcc24b52fec546f07e90abe593.png

我的IDE：

use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
use Album\Model\Album;
use Album\Form\AlbumForm; //COLORED RED "Form"

class AlbumController extends AbstractActionController
{
    protected $albumTable;

public function indexAction()
{
    return new ViewModel(array(
        'albums' => $this->getAlbumTable()->fetchAll(),
    ));
}

public function addAction()
{
    $form = new AlbumForm();
    $form->get('submit')->setValue('Add');

    $request = $this->getRequest();
    if ($request->isPost()) {
        $album = new Album(); //THE EEROR STRING THAT I GET IN PHP.
        $form->setInputFilter($album->getInputFilter());
        $form->setData($request->getPost());

        if ($form->isValid()) {
            $album->exchangeArray($form->getData());
            $this->getAlbumTable()->saveAlbum($album);

            // Redirect to list of albums
            return $this->redirect()->toRoute('album');
        }
    }
    return array('form' => $form);
}
