如何在用户定义的 symfony Bundle 中配置 Doctrine Entity Annotation 自动加载？

Question

当我尝试验证我的 symfony 架构时，我得到了错误：

[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 

我在这个问题中看到：Trouble with importing annotations，据说我们需要从 Doctrine Simple Annotation Reader 更改。尽管在自动加载器中进行捆绑配置似乎很奇怪，但我尝试通过 app/autoloader.php 进行配置：

use Doctrine\ORM\Configuration;

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

我也尝试过研究，看看是否可以找到类似的参数：

doctrine.orm.mappings.annotations.simple_annotations_reader

我可以设置为 false，但我找不到任何东西。

正如您将在下面看到的，我还尝试手动将我的包的映射添加到 config.yml 中的 ORM 设置。

    private $salt;

    /**

    private $roles;

所以我的问题是我怎样才能按照 Symfony 中公认的答案的建议去做（同时最好保持包相对可重用）。

谢谢

<?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 你必须为AnnotationRegistry注册加载器。

更详细的文档是available here。对于 symfony 项目，最简单的方法是使用 app/autoload 并包含以下内容：

<?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;

由于这种需要，bundle 通常使用 XML 配置容器、路由器等。

如果您更喜欢注释并且那是您的私有包，只需注册加载程序，如上所示。如果你想公开，我建议配置xmls。
