ZF2與Doctrine Mongo ODM

Question

我已關注如何將ZF2與Doctrine Mongo ODM集成？ 使用Doctrine Mongo ODM設置ZF2，

我可以將文檔保存到mongodb中，但是我無法使用以下代碼找到該文檔

$dm = $this->getLocator()->get('mongo_dm');
$result = $dm->find('Item', '4f9ea557eabc88e96f000000');
print_r($result);

這是錯誤日志

PHP Warning:  class_parents(): Class Item does not exist and could not be loaded in /var/www/vendor/DoctrineMongoODMModule/vendor/mongodb-odm/lib/Doctrine/ODM/MongoDB/Mapping/ClassMetadataFactory.php on line 347
PHP Warning:  array_reverse() expects parameter 1 to be array, boolean given in /var/www/vendor/DoctrineMongoODMModule/vendor/mongodb-odm/lib/Doctrine/ODM/MongoDB/Mapping/ClassMetadataFactory.php on line 347
PHP Warning:  Invalid argument supplied for foreach() in /var/www/vendor/DoctrineMongoODMModule/vendor/mongodb-odm/lib/Doctrine/ODM/MongoDB/Mapping/ClassMetadataFactory.php on line 347

我已經嘗試使用生成文檔

./vendor/DoctrineModule/bin/doctrine odm:generate:documents ./module/Application/src/Application/

Answer 1

$dm = $this->getLocator()->get('mongo_dm');
$result = $dm->find('Application\Document\Item', '4f9ea557eabc88e96f000000');

應該解決那些問題
