Question

Doctrine2中是否有任何方法可以通过复合主键数组找到实体包？

$primaryKeys = [ 
    ['key1'=>'val11', 'key2'=>'val21'], 
    ['key1'=>'val12', 'key2'=>'val22'] 
];

您必须将自定义方法添加到存储库。例如：

$repository = $em->getRepository('Application\Entity\Class');
$repository->findByPrimaryKeys();

在您的Application\Entity\Class存储库中：

/**
 * Find entity by primary keys.
 *
 * @param Parameters[] $array
 * @return Paginator
 */
public function findByPrimaryKeys(array $array)
{
    $qb = $this->createQueryBuilder('e');

    foreach($array as $index => $keys){
        $key1 = $index * 2 + 1;
        $key2 = $index * 2 + 2;
        $qb->orWhere(
            $qb->expr()->andX(
                $qb->expr()->eq('e.key1', '?'.$key1), 
                $qb->expr()->eq('e.key2', '?'.$key2)
            )
        );
        $qb->setParameter($key1, $keys['key1']);
        $qb->setParameter($key2, $keys['key2']);
    };
    return $qb->getQuery()->getResult();
}

也许还有其他方法，但这有效并导致遵循DQL查询：

SELECT e FROM Application\Entity\Class e WHERE 
    (e.key1= ?1 AND e.key2= ?2) 
OR 
    (e.key1= ?3 AND e.key2 = ?4)
