php - Zend Framework 1.11 与 Doctrine 2 和命名空间

Question

我一直在我的项目中使用 Doctrine，但没有明确命名我的任何类。这导致了一些问题，试图将我的代码组织到单独的子目录中(或者至少看起来是这样)。因此，我尝试在我的代码中实现 namespace ，但我很挣扎，并且尝试了这里的众多解决方案都无济于事，我需要问一下。

我有标准的项目结构:

application/
--models/
--services/
--controllers/
..etc

在我的 Bootstrap 中，我得到了以下内容(我的代码中没有命名空间但工作正常):

/**
* Initialize Doctrine
* @return Doctrine_Manager
*/
public function _initDoctrine() {
    // include and register Doctrine's class loader
    require_once('doctrine/Doctrine/Common/ClassLoader.php');

    $autoloader = \Zend_Loader_Autoloader::getInstance();

    require_once('doctrine/Doctrine/Common/ClassLoader.php');
    $commonLoader = new \Doctrine\Common\ClassLoader('Doctrine\Common', 'doctrine');
    $autoloader->pushAutoloader(array($commonLoader, 'loadClass'), 'Doctrine\Common');

    $dbalLoader = new \Doctrine\Common\ClassLoader('Doctrine\DBAL', 'doctrine');
    $autoloader->pushAutoloader(array($dbalLoader, 'loadClass'), 'Doctrine\DBAL');

    $ormLoader = new \Doctrine\Common\ClassLoader('Doctrine\ORM', 'doctrine');
    $autoloader->pushAutoloader(array($ormLoader, 'loadClass'), 'Doctrine\ORM');

    $modelLoader = new \Doctrine\Common\ClassLoader(NULL, APPLICATION_PATH . "/models");
    $autoloader->pushAutoloader(array($modelLoader, 'loadClass'), '');

    // create the Doctrine configuration
    $config = new \Doctrine\ORM\Configuration();

    // setting the cache ( to ArrayCache. Take a look at
    // the Doctrine manual for different options ! )
    $cache = new \Doctrine\Common\Cache\ArrayCache;
    $config->setMetadataCacheImpl($cache);
    $config->setQueryCacheImpl($cache);

    // choosing the driver for our database schema
    // we'll use annotations
    $driver = $config->newDefaultAnnotationDriver(
        APPLICATION_PATH . '/models'
        );
    $config->setMetadataDriverImpl($driver);

    // set the proxy dir and set some options
    $config->setProxyDir(APPLICATION_PATH . '/models/Proxies');
    $config->setAutoGenerateProxyClasses(true);
    //$config->setAutoGenerateProxyClasses(false);
    $config->setProxyNamespace('App\Proxies');

    // now create the entity manager and use the connection
    // settings we defined in our application.ini
    $connectionSettings = $this->getOption('doctrine');
    $conn = array(
    'driver'    => $connectionSettings['conn']['driv'],
    'user'      => $connectionSettings['conn']['user'],
    'password'  => $connectionSettings['conn']['pass'],
    'dbname'    => $connectionSettings['conn']['dbname'],
    'host'      => $connectionSettings['conn']['host']
    );
    $entityManager = \Doctrine\ORM\EntityManager::create($conn, $config);

    // push the entity manager into our registry for later use
    $registry = Zend_Registry::getInstance();
    $registry->entitymanager = $entityManager;

    return $entityManager;
}

当我添加

namespace models;

到我的每个模型类并更新 Bootstrap 如下我得到一个异常“类应用程序不存在”(应用程序是我的模型之一):

$modelLoader = new \Doctrine\Common\ClassLoader('models', APPLICATION_PATH . "/models");
$autoloader->pushAutoloader(array($modelLoader, 'loadClass'), 'models');

为了完整起见，我在我的 Controller 中引用了该模型，如下所示:

public function indexAction()
{
    $this->_helper->layout()->title = "Your applications";
    $this->_helper->layout()->description = "Create, edit and view all applications you have registered with us.";
    $this->view->applicationList = $this->entityManager->getRepository("Application")->findAll();
}

我错过了什么？我敢肯定这很明显，但我现在真的要拔头发了。

经过进一步搜索，我偶然发现了 this video (需要登录)。

基本上，我解决的方法(根据网络研讨会)是为我的实体命名空间并将它们保存在/library 目录下。然后，每当我需要在实际应用程序中使用它们时，我都会通过它们的命名空间进行访问。
