Zend framework Zend错误下的条令2:Class Entities\X没有名为Entities\Y的关联

我有一个相当奇怪的问题。我使用Zend框架1.11下的条令2。我有一个名为“Sessions”的数据库，是为学生提供的培训课程。每个会话都有一个关联的注释，称为SOPE注释。编辑：我现在包括这两个实体

}

调用$em->getRepository（'Entities\Sessions'）->findOneBy（'id'）时，一切正常——我得到了会话及其附带的SOPE注释。其他关联表的数据同上

但现在我正试图编写一个自定义存储库，以便在本次会话之前获取注释。功能如下：

<?php

namespace Repositories;

use Doctrine\ORM\EntityRepository;
use Doctrine\ORM\Query\ResultSetMapping;
use Doctrine\DBAL\Types\Type;

/**
 * Sessions
 */
class Sessions extends EntityRepository
{
    public function getPastSoapeNotes($params) {
        $studentId = $params['studentId'];
        $latestSession = $params['snDatetime'] ?: date('Y-m-d H:i');

        $qb = $this->_em->createQueryBuilder();

        $qb->select('n.subjective, n.objective, n.plan, n.action, n.education')
        ->from('Entities\Sessions', 'sn')
        ->innerJoin('sn.Entities\SnSoapeNotes', 'n');
        return $qb->getQuery()->getResult();
    }
}

---

我也尝试过在各种可能的组合中使用“mappedBy”和“inersedBy”注释，但没有效果；条令似乎找不到联系。我完全不知道发生了什么事。

我知道我做错了什么。在join语句中，我使用了'sn.Entities\SnSoapeNotes'，而我本应该只使用'soapeNote'，这是Sessions类中的属性，而不是表名本身。

会话实体在哪里定义？
