问doctrine2使用过多的SQL查询加载带有fetch模式的一对多关联。

class User{
    /**
     * @ORM\OneToMany(targetEntity="Address", mappedBy="user", indexBy="id", fetch="EAGER")
     */
    protected $addresses;
    public function __construct(){
        $this->addresses = new ArrayCollection();
    }
}

class Address{
    /**
     * @ORM\ManyToOne(targetEntity="User", inversedBy="addresses")
     * @ORM\JoinColumns({
     *   @ORM\JoinColumn(name="UserId", referencedColumnName="id")
     * })
     */
    private $user;
}

class UserRepository{
    public function findUsersWithAddresses(){
        return $this->getEntityManager()
            ->createQuery('SELECT u FROM MyBundle:User u ORDER BY u.name ASC')
            ->setFetchMode('MyBundle\Entity\User', 'addresses', \Doctrine\ORM\Mapping\ClassMetadata::FETCH_EAGER)
            ->setMaxResults(10)
            ->getResult();
    }
}
