类“SocialWall /控制器/ HomeController"不存在

我在我的web应用程序上有这个错误:

InvalidArgumentException in ControllerResolver.php line 160: Class "SocialWall/Controller/HomeController" does not exist.
    in ControllerResolver.php line 160
    at ControllerResolver->createController('SocialWall/Controller/HomeController::indexAction') in ControllerResolver.php line 76
    at ControllerResolver->getController(object(Request)) in HttpKernel.php line 136
    at HttpKernel->handleRaw(object(Request), '1') in HttpKernel.php line 68
    at HttpKernel->handle(object(Request), '1', true) in Application.php line 496
    at Application->handle(object(Request)) in Application.php line 477
    at Application->run() in index.php line 16

我使用Silex ~2.0，我刚刚重构了我的控制器列表，像这样:

My tree:

根/app/app.php
根/app/routes.php
• 根/src/控制器/HomeController.php
• 根/web/index . php

index . php:

<?php
/** Front controller */
require_once __DIR__.'/../vendor/autoload.php';
$app = new Silex'Application();
require __DIR__.'/../app/config/dev.php';
require __DIR__.'/../app/app.php';
require __DIR__.'/../app/routes.php';
$app->run();

routes.php

    <?php
    // Home page
    $app->get('/', "SocialWall/Controller/HomeController::indexAction")->bind('home');
    // Detailed info about an article
    $app->match('/article/{id}', "SocialWall/Controller/HomeController::articleAction")->bind('article');
    // Login form
    $app->get('/login', "SocialWall/Controller/HomeController::loginAction")->bind('login');   
//...

HomeController.php

    <?php
    namespace SocialWall'Controller;
    use Silex'Application;
    use Symfony'Component'HttpFoundation'Request;
    use SocialWall'Domain'Comment;
    use SocialWall'Form'Type'CommentType;
    class HomeController {
        /**
         * Home page controller.
         *
         * @param Application $app Silex application
         */
        public function indexAction(Application $app) {
            $articles = $app['dao.article']->findAll();
            return $app['twig']->render('index.html.twig', array('articles' => $articles));
        }
//...

    }
}

怎么了?

[编辑]好吧，我来修……在route.php函数的第二个参数中，我将所有的'/'替换为'''。最初phpStorm用红色下划线了所有的"'"，所以我用"/"代替了"'"。
