Symfony 2.5.5 & FOSUserBundle : the class . ..在链配置的命名空间中找不到

Question

最近，我开始使用 Symfony2。现在我想向我的网站添加用户管理引擎。

但是我遇到了一个问题。这就是我正在做的事情:

1. 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/
   

2. 好的，Symfony 2.5.5 就讲这么多。接下来，下载 FOSUserBundle 并创建自定义 bundle :

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

3. 在 Meiblorn\CoreBundle\Framework\Domain 命名空间中创建 User 类

   /**
    * User: Meiblorn
    * Date: 15/10/14
    * Time: 20:17
    */
   
   namespace Meiblorn\CoreBundle\Framework\Domain;
   
   use FOS\UserBundle\Model\User as FOSUserBundleUser;
   use Doctrine\ORM\Mapping as ORM;
   
   /**
    * @ORM\Entity
    * @ORM\Table(
    *      name = "users"
    * )
    */
   class User extends FOSUserBundleUser {
   
       /**
        * @ORM\Id
        * @ORM\Column(type="integer")
        * @ORM\GeneratedValue(strategy="AUTO")
        */
       protected $id;
   
       public function __construct() {
           parent::__construct();
           // your own logic
       }
   
   }
   
   ?>
   

4. 配置 security.yml 和 config.yml。最后，我得到了这个:

   AppKernel.php

   $bundles = array(
           new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
           new Symfony\Bundle\SecurityBundle\SecurityBundle(),
           new Symfony\Bundle\TwigBundle\TwigBundle(),
           new Symfony\Bundle\MonologBundle\MonologBundle(),
           new Symfony\Bundle\SwiftmailerBundle\SwiftmailerBundle(),
           new Symfony\Bundle\AsseticBundle\AsseticBundle(),
           new Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),
   
           new FOS\UserBundle\FOSUserBundle(),
   
           new Meiblorn\CoreBundle\MeiblornCoreBundle(),
   );
   

   config.yml

   imports:
       - { resource: parameters.yml }
       - { resource: security.yml }
   
   framework:

       spool:     { type: memory }
   
   fos_user:
       db_driver: orm
       firewall_name: prod
       user_class: Meiblorn\CoreBundle\Framework\Domain\User
   

   安全.yml

   security:
           encoders:
               FOS\UserBundle\Model\UserInterface: sha512
   
           role_hierarchy:
               ROLE_ADMIN:       ROLE_USER
               ROLE_SUPER_ADMIN: ROLE_ADMIN
   
           providers:
               fos_userbundle:
                   id: fos_user.user_provider.username
   
           firewalls:
               prod:
                   pattern: ^/
                   form_login:

                   logout:       true
                   anonymous:    true
               dev:
                   pattern: ^/(_(profiler|wdt)|css|images|js)/
                   security: false
   
           access_control:
               - { path: ^/login$, role: IS_AUTHENTICATED_ANONYMOUSLY }
               - { path: ^/register, role: IS_AUTHENTICATED_ANONYMOUSLY }
               - { path: ^/resetting, role: IS_AUTHENTICATED_ANONYMOUSLY }
               - { path: ^/admin/, role: ROLE_ADMIN }
   

这就是问题

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

MappingException: The class 'Meiblorn\CoreBundle\Framework\Domain\User' was not found in the chain configured namespaces FOS\UserBundle\Model
in /Library/WebServer/Documents/test.meiblorn.com/vendor/doctrine/common/lib/Doctrine/Common/Persistence/Mapping/MappingException.php line 37

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

请帮我解决此异常

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: Meiblorn\CoreBundle\Framework\Entity
              # alias: MyModels
              # is_bundle: true

Answer 1

首先，您需要在您的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，因此请尝试移动模型:src/Meiblorn/CoreBundle/Framework/Domain/User.php 到 src/Meiborn/CoreBundle/Entity/User.php 或 How do I change symfony 2 doctrine mapper to use my custom directory instead of my Entity Directory under the bundle
