最近，我开始使用Symfony2。现在我想在我的网站上添加一个用户管理引擎。

但我面临着一个问题。这就是我正在做的：

在创建/安装基本Symfony2项目方面：

$ composer create-project symfony/framework-standard-edition path/ "2.5.*"
$ mv path/* ./
$ rm -r path/

好的，Symfony 2.5.5到此为止。接下来，下载FOSUserBundle并创建一个自定义捆绑包：

$ composer require friendsofsymfony/user-bundle '~2.0@dev'
$ php app/console generate:bundle --namespace=Meiblorn/CoreBundle --format=yml

在Meiborn\CoreBundle\Framework\Domain命名空间中创建User类

/**
 * User: Meiblorn
 * Date: 15/10/14
 * Time: 20:17
 */
namespace MeiblornCoreBundleFrameworkDomain;
use FOSUserBundleModelUser as FOSUserBundleUser;
use DoctrineORMMapping as ORM;
/**
 * @ORMEntity
 * @ORMTable(
 *      name = "users"
 * )
 */
class User extends FOSUserBundleUser {
    /**
     * @ORMId
     * @ORMColumn(type="integer")
     * @ORMGeneratedValue(strategy="AUTO")
     */
    protected $id;
    public function __construct() {
        parent::__construct();
        // your own logic
    }
}
?>

配置security.yml和config.yml。最后，我得到了这个：

AppKernel.php

$bundles = array(
        new SymfonyBundleFrameworkBundleFrameworkBundle(),
        new SymfonyBundleSecurityBundleSecurityBundle(),
        new SymfonyBundleTwigBundleTwigBundle(),
        new SymfonyBundleMonologBundleMonologBundle(),
        new SymfonyBundleSwiftmailerBundleSwiftmailerBundle(),
        new SymfonyBundleAsseticBundleAsseticBundle(),
        new DoctrineBundleDoctrineBundleDoctrineBundle(),
        new FOSUserBundleFOSUserBundle(),
        new MeiblornCoreBundleMeiblornCoreBundle(),
);

security.yml

            - { path: ^/resetting, role: IS_AUTHENTICATED_ANONYMOUSLY }
            - { path: ^/admin/, role: ROLE_ADMIN }

这就是问题所在

In browser:  http://localhost/test.meiblorn.com/web/app_dev.php/

此外，Doctrine在调用Doctrine:schema:update时不会为此映射创建表

请帮我解决这个异常

更新！如何修复

我的命名空间的最终配置

orm:
        auto_generate_proxy_classes: "%kernel.debug%"
        auto_mapping: false
        mappings:
            FOSUserBundle: ~
            MeiblornCoreBundle:
                type: annotation
                dir: %kernel.root_dir%/../src/Meiblorn/CoreBundle/Framework/Entity
                prefix: MeiblornCoreBundleFrameworkEntity
              # alias: MyModels
              # is_bundle: true

首先需要在composer.js中配置psr-4自动加载，例如

"autoload": {
    "psr-4": {
      "Meiblorn\CoreBundle\": "src/Meiblorn/CoreBundle/"
    }
},

然后调用composer dumpautoload。

其次，我相信Doctrine希望实体位于文件夹Entity/中，所以尝试将您的模型从src/Meiblorn/CoreBundle/Framework/Domain/User.php移动到src/Meiblorn/CoreBundle/Entity/User.php，或者我如何更改symfony 2 Doctrine映射器以使用我的自定义目录，而不是捆绑包下的实体目录
