Question

我在运行IIS的Windows Server中安装了ZendFramework和Doctrine 2的小应用程序。

该应用程序在linux下运行良好，但在我的Windows机器上，我收到以下错误：

An error occurred during execution; please try again later.

奇怪的是，在错误中..类名是空的。可能是什么??

- 更新

所以，这就是我所说的

$this->getEntityManager()->getRepository('App\Common\Entity\Setting');

我的实体：

namespace App\Common\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity(repositoryClass="App\Common\Model\Repository\Settings")
 * @ORM\Table(name="settings")
 * @ORM\HasLifecycleCallbacks
 */
class Setting {

    /**
     * @ORM\Id
     * @ORM\Column(type="integer", nullable=false);
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

    /**
     * @ORM\ManyToOne(targetEntity="\Etc\App\Entity\User")
     * @ORM\JoinColumn(name="author", referencedColumnName="id", onDelete="SET NULL")
     */
    protected $author;

    public function getId() {
        return $this->id;
    }

    public function setId($id) {
        $this->id = $id;
    }

    public function getAuthor() {
        return $this->author;
    }

    public function setAuthor(\Etc\App\Entity\User $author) {
        $this->author = $author;
    }

}

- 更新2

namespace App\Common\Model\Repository;

class Settings {

    public function findAllFlatten() {
        // nothing relevant here.. 
    }

}



namespace Etc\App\Entity;

use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;

/**
 * @ORM\Entity(repositoryClass="Etc\App\Model\Repository\User")
 * @ORM\Table(name="user")
 * @ORM\HasLifecycleCallbacks
 */
class User {

    /**
     * @ORM\Id
     * @ORM\Column(type="integer", nullable=false);
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

    /**
     * @ORM\Column(type="string", length=48, unique=true, nullable=false)
     */
    protected $username;

    /**
     * @ORM\Column(type="string", length=64, nullable=false)
     */
    protected $password;

    public function getId() {
        return $this->id;
    }

    public function setId($id) {
        $this->id = $id;
    }

    public function getUsername() {
        return $this->username;
    }

    public function setUsername($username) {
        $this->username = $username;
    }

    public function getPassword() {
        return $this->password;
    }

    public function setPassword($password) {
        $this->password = $password;
    }

}

Answer 1

一切看起来都很正常，但唯一可以看到的是你的存储库没有扩展任何东西。它应该扩展doctrine repository类：

<? 
   namespace App\Common\Model\Repository; 

   use Doctrine\ORM\EntityRepository; 

   class Settings extends EntityRepository { 
       /// ... 

   }

另外，您是否配置了所有命名空间？请记住，在配置文件中，您有教条配置，例如：

'doctrine' => array (
                'driver' => array (
                        'mi_driver' => array (
                                'class' => 'Doctrine\ORM\Mapping\Driver\AnnotationDriver',
                                'cache' => 'array',
                                'paths' => array (
                                        __DIR__ . '/PATH_TO_CLASS_FILES' 
                                ) 
                        ),


                        'orm_default' => array (
                                'drivers' => array (
                                        "NAMESPACE"=>"mi_driver", "NAMESPACE2"=>"mi_driver",

                                ) 
                        ) 
                ) 
        ) 
);

另外，检查自动装带器是否配置正确。尝试在代码new App\Common\Entity\Setting()

中的任何位置创建类的实例

Answer 2

这可能有点晚了，但是在我看来，问题是作曲家的类缓存。我必须执行

composer dump-autoload

解决此问题。

在链式名称空间中找不到类
