如何在Doctrine2 QueryBuilder上水合多个实体

我有一个使用Doctrine2的symfony2应用程序，以及一些City，State，Country，Address的实体。

问题在于，如果我这样做：

    $queryBuilder = $this->em->createQueryBuilder();
    $queryBuilder
        ->select(array('country', 'state', 'city', 'address'))
        ->from('CouponiacsMainBundle:Country', 'country')
        ->leftJoin('country.states', 'state', 'WITH', 'state.name=:stateName OR state.shortName=:stateShortName')
        ->leftJoin('state.cities', 'city', 'WITH', 'city.name=:cityName')
        ->leftJoin('city.addresses', 'address', 'WITH', 'address.address=:address AND address.zip=:zip AND address.latitude=:latitude AND address.longitude=:longitude')
        ->where('country.name=:countryName OR country.shortName=:countryShortName')
        ->orderBy('city.name', 'DESC')
        ->setParameters(array(
            'countryName' => $country,
            'countryShortName' => $countryShort,
            'stateName' => $state,
            'stateShortName' => $stateShort,
            'cityName' => $city,
            'address' => $address['address'],
            'zip' => $address['zip'],
            'latitude' => $address['latitude'],
            'longitude' => $address['longitude'],
        ))
        ->setMaxResults(1);

结果集仅包含Country实体，但不包含State实体。我也尝试使用DQL进行相同的查询但没有成功：

$query = $this->em->createQuery('SELECT country, state, city, address
        FROM CouponiacsMainBundle:Country country
        LEFT JOIN country.states state WITH state.name=:stateName OR state.shortName=:stateShortName
        LEFT JOIN state.cities city WITH city.name=:cityName
        LEFT JOIN city.addresses address WITH address.address=:address AND address.zip=:zip AND address.latitude=:latitude AND address.longitude=:longitude
        WHERE country.name=:countryName OR country.shortName=:countryShortName
        ORDER BY city.name DESC
    ')->setParameters(array(
        'countryName' => $country,
        'countryShortName' => $countryShort,
        'stateName' => $state,
        'stateShortName' => $stateShort,
        'cityName' => $city,
        'address' => $address['address'],
        'zip' => $address['zip'],
        'latitude' => $address['latitude'],
        'longitude' => $address['longitude'],
    ));

如果我手动运行生成的SQL，则状态的结果是正常的，但在结果集上没有状态实体。结果是一个带有Country实体的数组，如果我执行getStates（），我就没有状态。

任何建议表示赞赏， 谢谢！

问题很可能是您在其他查询之前使用其中一些实体。并且Doctrine保留了一些缓存的东西。它取决于关联是完全加载还是仅部分加载。加载新的实体管理器或其他实体管理器应该可以解决问题。
