php – symfony2 doctrine ResultSetMapping错误

在这里,我尝试使用ResultSetMapping映射由nativeQuery生成的结果.但我不知道为什么学说总是抛出未定义的索引错误.有人可以帮我解决这个问题吗？
这是我的代码：
PlaceMarkerRepository：

namespace LeoFoodRadarBundleEntity;

use DoctrineORMEntityRepository;
use DoctrineORMQueryResultSetMappingBuilder;


/**
 * PlaceMarkerRepository
 *
 * This class was generated by the Doctrine ORM. Add your own custom
 * repository methods below.
 */
class PlaceMarkerRepository extends EntityRepository
{
    public function findNearBy($query,$lat, $lng, $radius){

        $rsm = new ResultSetMappingBuilder($this->getEntityManager());
        // $rsm = new ResultSetMappingBuilder();
        // $rsm->addRootEntityFromClassMetadata('LeoFoodRadarBundle:PlaceMarker', 'p');
        // $rsm->addJoinedEntityFromClassMetadata('LeoFoodRadarBundle:Coordinate', 'c', 'p', 'coordinate', array('id' => 'coordinate_id'));

        $rsm->addEntityResult('LeoFoodRadarBundle:PlaceMarker', 'p');
        $rsm->addFieldResult('p', 'id', 'id');
        $rsm->addFieldResult('p', 'name', 'name');
        $rsm->addJoinedEntityResult('LeoFoodRadarBundle:Coordinate' , 'c', 'p', 'coordinate');
        $rsm->addFieldResult('c', 'coordinate_id', 'id');
        $rsm->addFieldResult('c', 'latitude', 'latitude');
        $rsm->addFieldResult('c', 'longitude', 'longitude');



        $sql ="SELECT p.id, p.name, c.latitude, c.longitude, c.id as coordinate_id
                FROM placeMarker p join coordinate c on p.coordinate_id = c.id
                ";

         $this->getEntityManager()->createNativeQuery($sql, $rsm)->getResult();



    }
}

和PlaceMark：

namespace LeoFoodRadarBundleEntity;

use DoctrineORMMapping as ORM;

/**
 * LeoFoodRadarBundleEntityPlaceMarker
 *
 * @ORMTable(name="placeMarker")
 * @ORMEntity(repositoryClass="LeoFoodRadarBundleEntityPlaceMarkerRepository")
 */
class PlaceMarker {

    /**
     * @var integer $id
     *
     * @ORMColumn(name="id", type="integer")
     * @ORMId
     * @ORMGeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @var Coordinate coordinate 
     * @ORMOneToOne(targetEntity="Coordinate") 
     * @ORMJoinColumn(name="coordinate_id", referencedColumnName="id")
     */
    private $coordinate;

    /**
     *
     * @var Address address
     * @ORMOneToOne(targetEntity="Address") 
     * @ORMJoinColumn(name="address_id", referencedColumnName="id")
     */
    private $address;


    /**
     *
     * @ORMColumn(name="name", type="string", length=100)
     */
    private $name;

    /**
     * Get id
     *
     * @return integer 
     */
    public function getId() {
        return $this->id;
    }

    /**
     * Set coordinate
     *
     * @param LeoFoodRadarBundleEntityCoordinate $coordinate
     * @return PlaceMarker
     */
    public function setCoordinate(LeoFoodRadarBundleEntityCoordinate $coordinate = null) {
        $this->coordinate = $coordinate;

        return $this;
    }

    /**
     * Get coordinate
     *
     * @return LeoFoodRadarBundleEntityCoordinate 
     */
    public function getCoordinate() {
        return $this->coordinate;
    }

    /**
     * Set address
     *
     * @param LeoFoodRadarBundleEntityAddress $address
     * @return PlaceMarker
     */
    public function setAddress(LeoFoodRadarBundleEntityAddress $address = null) {
        $this->address = $address;

        return $this;
    }

    /**
     * Get address
     *
     * @return LeoFoodRadarBundleEntityAddress 
     */
    public function getAddress() {
        return $this->address;
    }



    /**
     * Set name
     *
     * @param string $name
     * @return PlaceMarker
     */
    public function setName($name)
    {
        $this->name = $name;

        return $this;
    }

    /**
     * Get name
     *
     * @return string 
     */
    public function getName()
    {
        return $this->name;
    }
}

坐标：

<?PHP

namespace LeoFoodRadarBundleEntity;

use DoctrineORMMapping as ORM;

/**
 * LeoFoodRadarBundleEntityCoordinate
 *
 * @ORMTable(name="coordinate")
 * @ORMEntity
 */
class Coordinate
{
    /**
     * @var integer $id
     *
     * @ORMColumn(name="id", type="integer")
     * @ORMId
     * @ORMGeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @ORMColumn(type="float") 
     */
    private $longitude;

    /**
     * @ORMColumn(type="float") 
     */
    private $latitude;

    /**
     * Get id
     *
     * @return integer 
     */
    public function getId()
    {
        return $this->id;
    }


    /**
     * Get longitude
     * @return float 
     */
    public function getLongitude() {
        return $this->longitude;
    }

    /**
     * Set longitude
     */
    public function setLongitude($longitude) {
        $this->longitude = $longitude;
    }

    /**
     * Get Latitude
     * @return float 
     */
    public function getLatitude() {
        return $this->latitude;
    }

    /**
     * Set Latitude
     */
    public function setLatitude($latitude) {
        $this->latitude = $latitude;
    }


}

此声明引起的错误：

$targetClass = $this->_ce[$relation['targetEntity']];

有关错误的信息是：

解决方法:

最后,我找到了导致这个问题的原因.我认为这是因为resultsetmapping在内部运行,所以它无法理解Symfony提供的逻辑名称.此问题的解决方案是将逻辑名称更改为完整路径名称.然后它会工作.
