使用原则2时没有找到模型;Zend框架

我开始了一个新项目，想在Zend框架(1.11)中使用Doctrine 2。

我在Bootstrap &

这是我创建的第一个模型:

<?php
namespace Entities;
/**
 * @Entity
 * @Table(name="posts")
 */
class Post
{
    /** @Id @Column(type="integer") @GeneratedValue */
    public $id;
    /** @Column(length=100,nullable=true) */
    public $title;
    /** @Column(length=2000) */
    public $message;
    /** @Column(type="integer") */
    public $userId;
    /** @Column(type="timestamp") */
    public $dateAdded;
}

这里是控制器:

<?php
class CityController extends Zend_Controller_Action
{
    public function init()
    {
        /* Initialize action controller here */
    }
    public function indexAction()
    {
        $em = Zend_Registry::get('em');
        $group = $em->find('Entities'Post', 1);
    }

}

当我尝试访问Entities'Post模型时，它只是错误地说它不存在。我确定这是Zend命名约定的问题，但我尝试了一些不同的方法，似乎都不起作用。

任何想法?我确实看了所有我能找到的Doctrine 2/Zend教程，但没有一个有多大帮助。

* UPDATE *

下面是我在bootstrap中的Doctrine init:

public function _initDoctrine() {
    // include and register Doctrine's class loader
    require_once('Doctrine/Common/ClassLoader.php');
    $classLoader = new 'Doctrine'Common'ClassLoader(
        'Doctrine',
        APPLICATION_PATH . '/../library/'
    );
    $classLoader->register();
    // 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->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->em = $entityManager;
    return $entityManager;
}

下面是doctrine的配置(在application.ini中):

doctrine.conn.host = 'localhost'
doctrine.conn.user = '****'
doctrine.conn.pass = '****'
doctrine.conn.driv = 'pdo_mysql'
doctrine.conn.dbname = '****'
doctrine.path.models = APPLICATION_PATH "/models"

可以看到，它正在寻找APPLICATION_PATH "/models"
