我有以下问题：学说得到一个DQL查询结果以嵌套形式
我有下面的方法获取船舶的GPS点：
/**
* @param array $mmsids
* @param unknown $longituteMin
* @param unknown $longtitudeMax
* @param unknown $latitudeMin
* @param unknown $latitudeMax
* @param \Datetime $timeInterval
*
* @throws EmptyParamGivenException
* @throws Exception
*
* @return Vesel[] with their routes
*/
public function getRoutes(array $mmsids=[],
$longituteMin=null,
$longtitudeMax=null,
$latitudeMin=null,
$latitudeMax=null,
\DateTime $fromDate=null,
\DateTime $toDate=null
) {
$em=$this->getEntityManager();
$query=$em->createQueryBuilder('v')
->from('AppBundle:Vesel', 'v')
->innerJoin('v.veselMoveStatuses','m')
->select('v.mmsi,m.logtitude,m.latitude,m.timestamp')
->addOrderBy('v.mmsi','ASC')
->addOrderBy('m.timestamp','DESC');
if(!empty($longituteMin)){
$query->andWhere('m.logtitude >= :long_min')->setParameter(':long_min',$longituteMin);
}
if(!empty($longtitudeMax)) {
$query->andWhere('m.logtitude <= :long_max')->setParameter(':long_max',$longituteMax);
}
if(!empty($latitudeMin)){
$query->andWhere('m.latitude >= :lat_min')->setParameter(':lat_min',$latitudeMin);
}
if(!empty($latitudeMax)){
$query->andWhere('m.latitude <= :lat_max')->setParameter(':lat_max',$latitudeMin);
}
if(!empty($mmsids)){
$query->andWhere('v.mmsi IN (:mmsids)')->setParameter('mmsids', $mmsids,\Doctrine\DBAL\Connection::PARAM_STR_ARRAY);
}
$paramsToValidate=[RouteInputParameter::PARAM_DATE_FROM=>$fromDate,RouteInputParameter::PARAM_DATE_TO=>$toDate];
if($fromDate!==null && $toDate!==null){
InputValidator::dateRangeValidation($paramsToValidate,RouteInputParameter::PARAM_DATE_FROM,RouteInputParameter::PARAM_DATE_TO);
$query->andWhere('m.timestamp BETWEEN :date_min AND :date_max')
->setParameters(['date_min'=>$fromDate,'date_max'=>$toDate]);
} else if($fromDate!==null) {
$query->andWhere('m.timestamp <= :date_min')
->setParameters(['date_min'=>$fromDate]);
} else if($toDate!==null) {
$query->where('m.timestamp >= :date_max')
->setParameters(['date_max'=>$toDate]);
}
$query = $query->getQuery();
return $query->getResult();
}
我想什么实现这一目标，我想在这样的一个嵌套的方式产生结果：
[
[
"mmsi"=>"^somevalue^"
points=>[
"longtitude":"^longtitude_value^",
"latitude":"^latitude_value^",
"time":"^time_value^"
],
....
],
....
]
你有什么想法，如果有一个内部主义机制，允许我这样做，或者我应该实现自己的？
的Vessel实体是：
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* @ORM\Entity
* @ORM\Table(name="vessel",indexes={
* @ORM\Index(name="mmsi",columns={"mmsi"})
* })
*/
class Vesel
{
/**
* @ORM\Column(type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
* @var integer
*/
private $id;
/**
* @ORM\Column(type="integer",name="mmsi")
* @var integer
*/
private $mmsi;
/**
* @ORM\OneToMany(targetEntity="VesselMoveStatus",mappedBy="vesel")
* @var \Doctrine\Common\Collections\Collection
*/
private $veselMoveStatuses;
/**
* Constructor
*/
public function __construct($mmsi)
{
$this->veselMoveStatuses = new \Doctrine\Common\Collections\ArrayCollection();
$this->setMmsi($mmsi);
}
/**
* Get id
*
* @return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set mmsi
*
* @param integer $mmsi
*
* @return Vesel
*/
public function setMmsi($mmsi)
{
$this->mmsi = $mmsi;
return $this;
}
/**
* Get mmsi
*
* @return integer
*/
public function getMmsi()
{
return $this->mmsi;
}
/**
* Add veselMoveStatus
*
* @param \AppBundle\Entity\VesselMoveStatus $veselMoveStatus
*
* @return Vesel
*/
public function addVeselMoveStatus(\AppBundle\Entity\VesselMoveStatus $veselMoveStatus)
{
$this->veselMoveStatuses[] = $veselMoveStatus;
return $this;
}
/**
* Remove veselMoveStatus
*
* @param \AppBundle\Entity\VesselMoveStatus $veselMoveStatus
*/
public function removeVeselMoveStatus(\AppBundle\Entity\VesselMoveStatus $veselMoveStatus)
{
$this->veselMoveStatuses->removeElement($veselMoveStatus);
}
/**

*
* @return \Doctrine\Common\Collections\Collection
*/
public function getVeselMoveStatuses()
{
return $this->veselMoveStatuses;
}
}
并涉及到VesselMoveStatus实体：
