我想在我的 Zend Framework-Application 中结合使用 Doctrine 2 和“l3pp4rd/DoctrineExtensions”。 但我只收到以下错误消息:

The annotation "@Doctrine\ORM\Mapping\Entity" in class Entities\USER_User does not exist, or could not be auto-loaded.

应用程序\bootstrap.php

  protected function _initDoctrine() {

    require_once('Doctrine/Common/ClassLoader.php');
    $autoloader = Zend_Loader_Autoloader::getInstance();

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

    $classLoader = new \Doctrine\Common\ClassLoader('Entities',
      realpath(Zend_Registry::get('config')->resources->entityManager->connection->entities), 'loadClass');
    $autoloader->pushAutoloader(array($classLoader, 'loadClass'), 'Entities');

    $classLoader = new \Doctrine\Common\ClassLoader('Repositories',
      realpath(Zend_Registry::get('config')->resources->entityManager->connection->entities), 'loadClass');
    $autoloader->pushAutoloader(array($classLoader, 'loadClass'), 'Repositories');
  }

library\My\Resource\Entitymanager.php 位于 http://www.gediminasm.org/article/annotation-reference

class My_Resource_Entitymanager extends Zend_Application_Resource_ResourceAbstract
{

    public function init()
    {

应用\模型\USER_User.php

namespace Entities;

use Doctrine\ORM\Mapping as ORM;
/**

 * @ORM\HasLifecycleCallbacks
 */
class USER_User
{
    /**
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;
    /**
     * Retrieve user id
     */
    public function getId()
    {
        return $this->id;
    }
}

应用\配置\application.ini

...
includePaths.library = APPLICATION_PATH "/../library/Doctrine"
...
pluginPaths.My_Resource = "My/Resource"
...
autoloaderNamespaces[] = "Doctrine"
autoloaderNamespaces[] = "Gedmo"
autoloaderNamespaces[] = "Symfony"
autoloaderNamespaces[] = "My"
...
resources.entityManager.connection.driver = "pdo_mysql"
resources.entityManager.connection.host = "localhost"
resources.entityManager.connection.dbname = "test"
resources.entityManager.connection.user = "test"
resources.entityManager.connection.password = "test"
resources.entityManager.connection.entities = APPLICATION_PATH "/models"
resources.entityManager.connection.proxies.location = APPLICATION_PATH "/models/Proxies"
resources.entityManager.connection.proxies.ns = "Proxies"

; According to Doctrine manual, this should be true for
; development, and false for production
resources.entityManager.connection.proxies.generate = true
...

有什么想法可以让它发挥作用吗？

最佳答案

解决了这个问题的答案: doctrine2 autloader with cli must use AnnotationRegistry

添加到库\My\Resource\Entitymanager.php

use Doctrine\Common\Annotations\AnnotationRegistry; 
class My_Resource_Entitymanager extends Zend_Application_Resource_ResourceAbstract
{

    public function init()
    {
        AnnotationRegistry::registerFile(__DIR__ . '/../../Doctrine/ORM/Mapping/Driver/DoctrineAnnotations.php');
        // WARNING: setup, assumes that autoloaders are set
        // configuration settings from the application.ini file
        ...

我也删除了

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

来自 application\bootstrap.php

感谢阅读我的问题!

关于php - 类 Entities\USER_User 中的注释 "@Doctrine\ORM\Mapping\Entity"不存在，或者无法自动加载，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/12422314/
