$aclQueryHelper = $this->get('kos4live.acl_doctrine_query.helper');
$em = $this->getDoctrine()->getManager();
$qb = $em->createQueryBuilder();

$qb = $qb->select('p')
    ->from('Entity\Product', 'p');
$qb->setMaxResults(10);

$permissions = array('view');
$user = $this->getUser();

// The returned query object is a clone, you can alway use $qb->getQuery() to get the original query object
$query = $aqlQueryHelper->apply($qb, $permissions, $user);

$result = $query->getArrayResult();

apply() 函数的 $user 参数是可选的，如果未设置或为 null，则安全上下文将用来确定当前用户。

别忘了在 AppKernel.php 中添加新的 kos4live\AclDoctrineQueryBundle\kos4liveAclDoctrineQueryBundle()。
