我正在尝试在我的 zend 2 项目中实现理论水合器。我正在使用学说的官方文档

我收到两个警告和一个错误。以下是页面顶部的警告。

警告：缺少 DoctrineModule\Stdlib\Hydrator\DoctrineObject::__construct() 的参数 2，在第 16 行的 /path/to/my/project/module/Notes/src/Notes/Form/AssignForm.php 中调用并在 / 中定义path/to/my/project/vendor/doctrine/doctrine-module/src/DoctrineModule/Stdlib/Hydrator/DoctrineObject.php 在第 71 行

注意：未定义变量：第 76 行 /path/to/my/project/vendor/doctrine/doctrine-module/src/DoctrineModule/Stdlib/Hydrator/DoctrineObject.php 中的 targetClass

这是错误：

An error occurred 执行过程中发生错误；请稍后再试。附加信息：Doctrine\Common\Persistence\Mapping\MappingException

文件：

/path/to/my/project/vendor/doctrine/common/lib/Doctrine/Common/Persistence/Mapping/MappingException.php:96

信息：

Class '' does not exist

这是我的实体： 

use Doctrine\ORM\Mapping as ORM;

 }

 /**

 public function getVsiStatus()

}

这是我的控制器

<?php
namespace Notes\Controller;

use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;

use Doctrine\ORM\EntityManager; 
use Application\Entity\Assigned;
use Notes\Form\AssignForm;
use Notes\Form\NotesFieldset;

class NotesController extends AbstractActionController
{

protected $objectManager;

public function indexAction()
{

     return new ViewModel();
}

public function addAction()
{
    // Get your ObjectManager from the ServiceManager
$objectManager = $this->getOBjectManager();
$form = new AssignForm($objectManager);

// Create a new, empty entity and bind it to the form
$assigned = new Assigned();
$form->bind($assigned);

if ($this->request->isPost()) {
    $form->setData($this->request->getPost());

    if ($form->isValid()) {
        $objectManager->persist($assigned);
        $objectManager->flush();
    }
}

return array('form' => $form);


}

public function getOBjectManager(){
    if(!$this->objectManager){
        $this->objectManager = $this->getServiceLocator()
                                ->get('Doctrine\ORM\EntityManager');
    }
    return $this->objectManager;
}

}

这是我的表单类：

<?php
namespace Notes\Form;
use Doctrine\Common\Persistence\ObjectManager;
use DoctrineModule\Stdlib\Hydrator\DoctrineObject as DoctrineHydrator;
use Zend\Form\Form;
use Notes\Form\NotesFieldset;

class AssignForm extends Form
{
public function __construct(ObjectManager $objectManager)
{
    parent::__construct('assigned');

    // The form will hydrate an object of type "BlogPost"
    $this->setHydrator(new DoctrineHydrator($objectManager));

    // Add the user fieldset, and set it as the base fieldset
    $notesFieldset = new NotesFieldset($objectManager);
    $notesFieldset->setUseAsBaseFieldset(true);
    $this->add($notesFieldset);

    // … add CSRF and submit elements …

    // Optionally set your validation group here

}
}

这是 Fieldset 类

<?php
namespace Notes\Form;
use Application\Entity\Assigned;
use Doctrine\Common\Persistence\ObjectManager;
use DoctrineModule\Stdlib\Hydrator\DoctrineObject as DoctrineHydrator;
use Zend\Form\Fieldset;
use Zend\InputFilter\InputFilterProviderInterface;

class NotesFieldset extends Fieldset implements InputFilterProviderInterface
{
    protected $inputFilter;

   public function __construct(ObjectManager $objectManager)
    {
        parent::__construct('assigned');

        $this->setHydrator(new DoctrineHydrator($objectManager))
             ->setObject(new Assigned());

        $this->add(array(
            'type' => 'Zend\Form\Element\Hidden',
            'name' => 'id'
        ));

        $this->add(array(
            'type'    => 'Zend\Form\Element\Text',
            'name'    => 'loan_number',
            'options' => array(
                'label' => 'Loan Number'
            )
        ));

        $this->add(array(
            'type'    => 'Zend\Form\Element\Text',
            'name'    => 'claim_status',
            'options' => array(
                'label' => 'Claim Status'
            )
        ));

        $this->add(array(
            'type'    => 'Zend\Form\Element\Text',
            'name'    => 'hold_date',
            'options' => array(
                'label' => 'Hold Date'
            )
        ));

        $this->add(array(
            'type'    => 'Zend\Form\Element\Text',
            'name'    => 'vsi_date',
            'options' => array(
                'label' => 'VSI Date'
            )
        ));

         $this->add(array(
            'type'    => 'Zend\Form\Element\Text',
            'name'    => 'hold_status',
            'options' => array(
                'label' => 'Hold Status'
            )
        ));

        $this->add(array(
            'name' => 'vsi_status',
            'attributes' => array(
                'type'  => 'text',
            ),
            'options' => array(
                'label' => 'VSI Status',
            ),
        ));

        $this->add(array(
            'name' => 'submit',
            'attributes' => array(
                'type'  => 'submit',
                'value' => 'Go',
                'id' => 'submitbutton',
            ),
        ));
    }

   /**
   * Define InputFilterSpecifications
   *
   * @access public
   * @return array
   */

    public function getInputFilterSpecification()
    {

        return array(
            'id' => array(
                'required' => false
            ),
            'name' => array(
                'required' => true
            ),
            'loan_number' => array(
                'required' => true
            ),
            'claim_status' => array(
                'required' => true
            ),
            'hold_date' => array(
                'required' => true
            ),
            'hold_status' => array(
                'required' => true
            ),
            'vsi_date' => array(
                'required' => true
            ),
            'hold_status' => array(
                'required' => true
            ),
        );

    }
}

它是说：类''不存在。但是消息中没有给出类名。

除此之外，我将这些库用于我的作曲家的教义。

"doctrine/doctrine-orm-module": "0.7.*",
"doctrine/migrations": "dev-master",
"doctrine/common": "2.4.*@dev",
"doctrine/annotations": "1.0.*@dev",
"doctrine/data-fixtures": "1.0.*@dev",
"doctrine/cache": "1.0.*@dev",
"zf-commons/zfc-user-doctrine-orm": "dev-master",

请告诉我我的实现中缺少什么。我在 github 中有一个关于不完整示例文档的教义的未解决问题。这是问题的链接。如果是这种情况，那么请建议我正确实施。

您缺少目标类参数：

$this->setHydrator(new DoctrineHydrator($objectManager));

应该：

$this->setHydrator(
  new DoctrineHydrator(
    $objectManager,
    'the\target\entity' // <-- the target entity class name
  )
);

targetClass用于DoctrineObject获取水合实体的元数据。你可以看到这个DoctrineModule\Stdlib\Hydrator\DoctrineObject::__construct()：

$this->metadata = $objectManager->getClassMetadata($targetClass);
