問題描述

嘗試運行簡單命令$ msg = $ this-> _ em-> find（“ Entities \\ Message”，1）; 在我的IndexController中，出現以下錯誤： 

( ! ) Warning: class_parents() [function.class-parents]: Class Entities\Message does not exist and could not be loaded in C:\wamp\www\KosherOven\library\Doctrine\ORM\Mapping\ClassMetadataFactory.php on line 222

這是我的理論引導代碼： 

protected function _initDoctrine()
{
    /* Autoload classes */
    require_once 'Doctrine/Common/ClassLoader.php';
    $classLoader = new Doctrine\Common\ClassLoader('Doctrine');
    $classLoader->register();
    // load the doctrine class loader for Symfony library components
    $classLoader = new \Doctrine\Common\ClassLoader('Symfony', 'Doctrine');
    $classLoader->register();
    $classLoader = new \Doctrine\Common\ClassLoader('Entities', APPLICATION_PATH . '/models');
    $classLoader->register();

    /* Choose cache */

    if (APPLICATION_ENV == "development") {
        $cache = new \Doctrine\Common\Cache\ArrayCache;
    } else {
        //$cache = new \Doctrine\Common\Cache\ApcCache;
        $cache = new \Doctrine\Common\Cache\ArrayCache;
    }

    $config = new \Doctrine\ORM\Configuration;
    $config->setMetadataCacheImpl($cache);

    $driverImpl = $config->newDefaultAnnotationDriver(APPLICATION_PATH . '/configs/doctrine/Mapping');
    $config->setMetadataDriverImpl($driverImpl);
    $config->setQueryCacheImpl($cache);
    $config->setProxyDir(APPLICATION_PATH . '/Proxies');
    $config->setProxyNamespace('Proxies');

    if (APPLICATION_ENV == "development") {
        $config->setAutoGenerateProxyClasses(true);
    } else {
        $config->setAutoGenerateProxyClasses(false);
    }

    $configObj = $this->_initConfig();

    $connectionOptions = array(
        'driver'   => $configObj->database->adapter,
        'dbname'   => $configObj->database->params->dbname,
        'host'     => $configObj->database->params->host,
        'user'     => $configObj->database->params->username,
        'password' => $configObj->database->params->password
    );
    $em = \Doctrine\ORM\EntityManager::create($connectionOptions, $config);

    Zend_Registry::set('em', $em);
}

我正在使用Doctrine 2.0.4。

我想不出任何其他信息，但是如果需要，我很樂意添加更多信息。

2 個解決方案

解決方案1

確保您在application/models/Entities/Message.php具有以下類 

namespace Entities;

/**
 * @Entity
 */
class Message
{
    // ...

另外，我不確定這條線 

// load the doctrine class loader for Symfony library components
$classLoader = new \Doctrine\Common\ClassLoader('Symfony', 'Doctrine');

這不是說Symfony名稱空間/文件夾在Doctrine目錄中嗎？

編輯：我猜應該是這樣 

$classLoader = new \Doctrine\Common\ClassLoader('Symfony');

更新

我想我明白了什么。 您沒有告訴注釋驅動程序在哪里可以找到您的實體。

我認為這條線

$ driverImpl = $ config-> newDefaultAnnotationDriver（APPLICATION_PATH。'/ configs / doctrine / Mapping'）;

應該 

$driverImpl = $config->newDefaultAnnotationDriver(APPLICATION_PATH . '/models/Entities');

參見http://www.doctrine-project.org/docs/orm/2.0/en/reference/configuration.html

我強烈建議您從Guilherme Blanco查看Bisna集成-https: //github.com/guilhermeblanco/ZendFramework1-Doctrine2

我在這里也有一種ZF / Doctrine2應用程序框架，歡迎您關注-https: //github.com/philBrown/ZFDoctrineSkeleton

看起來您沒有將Doctrine，Symfony和Entities類加載器推到Zend自動加載器上： 

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

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

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

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