ZF2：Zend Framework 2.3.0：致命錯誤：class IndexController not found

Question

我正在通過構建教程應用程序來學習Zend Framework。 我已經檢查過我的代碼幾次，並將其與本書的源代碼 進行比較。

我不能想出解決方案或解釋爲什麼 此錯誤不斷髮生。誰能幫我嗎？

Fatal error: Class 'Wall\Controller\IndexController' not found in C:\xampp\htdocs\Connect\client\vendor\zendframework\zendframework\library\Zend\ServiceManager\AbstractPluginManager.php on line 170

的錯誤是你的自動加載配置中極有可能

public function getAutoloaderConfig() 
{ 
    return array(
     'Zend\Loader\StandardAutoloader' => array(
      'namespaces' => array(
       __NAMESPACE__ => __DIR__ . '/src/' , __NAMESPACE__ 
               // ^-- that should be a DOT . 
      ), 
     ), 
    ); 
}
