如何在用戶定義的symfony Bundle中配置Doctrine Entity Annotation自動加載？

Question

當我嘗試驗證我的symfony的架構，我得到的錯誤：

[Doctrine\Common\Annotations\AnnotationException]        
[Semantical Error] The annotation "@Doctrine\Orm\Mapping\Entity" in class C 
hill\EmailUser\Entity\EmailUser does not exist, or could not be auto-loaded 

我看到，在這個問題：Trouble with importing annotations，它是說，我們需要從學說簡單的註解讀者改變。儘管這似乎有些奇怪，使束配置在自動裝，我想這樣做，通過應用程序/ autoloader.php：

use Doctrine\ORM\Configuration; 

path = __DIR__."/../vendor/path/to/annotationDriver.php" 
Configuration::newDefaultAnnotationDriver(path, false); 

我還試圖研究，看看是否能找到像一個參數：

doctrine.orm.mappings.annotations.simple_annotations_reader 

，我可以設置爲false，但我找不到任何東西。

正如你在下面看到的，我也嘗試了爲我的包添加映射到config.yml中的ORM設置。

所以我的問題我該如何做到Symfony公認的答案是建議的（儘管最好讓這個軟件包相對可重用）。

<?php 

use Doctrine\Common\Annotations\AnnotationRegistry; 
use Composer\Autoload\ClassLoader; 

/** @var ClassLoader $loader */ 
$loader = require __DIR__.'/../vendor/autoload.php'; 
AnnotationRegistry::registerLoader(array($loader, 'loadClass')); 
return $loader;        

Answer 1

AFAIK你必須爲AnnotationRegistry寄存器加載。

更詳細的文檔是available here。在symfony項目的情況下，最簡單的方法是使用app/autoload具有下列內容：

<?php 

use Composer\Autoload\ClassLoader; 
use Doctrine\Common\Annotations\AnnotationRegistry; 

/** 
* @var ClassLoader $loader 
*/ 
$loader = require __DIR__.'/../vendor/autoload.php'; 

AnnotationRegistry::registerLoader(array($loader, 'loadClass')); 

return $loader; 

，因爲需要的，通常捆綁使用XML配置的容器，路由器等。

如果您更喜歡註釋，那就是您的私有捆綁軟件只需註冊載入器，如上所示。如果你想公開，我建議xmls的配置。
