别名 “custom.controllers.ExampleController.php” 无效

Question

这是错误：

Alias "custom.controllers.ExampleController.php" is invalid. Make sure it points to an existing PHP file and the file is readable.

我的代码下面给出

main.php=> 
    return 
    array(
     'controllerMap' => array(
      'product' => array(
       'class' => 'custom.controllers.Product.php', 
      ), 
     ), 

     'import' => array(
      'custom.mycompany.*', 
     ), 

     'components' => 
      array(
       'widgetHandler' => array(
        //Load a component 
        'class' => 'custom.mycompany.mywidget.mywidget', 
       ), 

      ) 
); 

Product.php=> 

    <?php 

class Product extends Controller 
{ 
    public function actionIndex() 
    { 
     echo "this is the default index function"; 
    } 

    public function actionTest() 
    { 
     echo "This is the test function"; 
    } 
} 

我使用光速厘米。

为Yii2/PHP类的符号不是基于点斜线，但是基于

'class' => 'custom\controllers\Product.php', 

（并在代码中有不ExampleController ..）

见第https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-0.md

和https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-4-autoloader.md

对于Yii2编码标准的建议
