Zend2 框架 - 给映射异常的 Doctrine ORM

Question

我正在尝试将 Doctrine 2 ORM 用于我的 Zend2 应用程序之一。我在 composer 的帮助下使用 Doctrine 模块在应用程序中进行了设置。

我能够将数据持久化到数据库中，但是当我在对象管理器上进行 find() 调用时，它给了我一个映射异常，并显示以下消息。

Doctrine\Common\Persistence\Mapping\MappingException
File:
/vendor/doctrine/common/lib/Doctrine/Common/Persistence/Mapping/MappingException.php:96
Message:
Class 'User' does not exist

以下是在Application模块配置文件下添加的Doctrine设置

'driver' => array(
                'application_entities' => array(
                        'class' =>'Doctrine\ORM\Mapping\Driver\AnnotationDriver',
                        'cache' => 'array',
                        'paths' => array(__DIR__ . '/../src/Application/Entity')
                ),

                'orm_default' => array(
                        'drivers' => array(
                                'Application\Entity' => 'application_entities'
                        )
                )
        )
),

这是在 Application\src\Entity 文件夹下创建的用户实体

<?php
namespace Application\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
 *  @ORM\Entity

class User {
/**
 * @ORM\Id

    return $this->network_name;

    return $this->location;
}

public function setLocation($location) {
    $this->location = $location;
    return $this;
}

public function getFirstName() {
    return $this->first_name;
}

    $this->first_name = $first_name;
    return $this;
}

public function getLastName() {
    return $this->last_name;
}

/**

public function setLastName($last_name) {
    $this->last_name = $last_name;
    return $this;
}

/**

public function getUrl() {
    return $this->url;
}

/**

 */
public function setUrl($url) {
    $this->url = $url;
    return $this;
}

/**

 */
public function getImgUrl() {
    return $this->img_url;
}

/**
 * @param string $img_url
 */
public function setImgUrl($img_url) {
    $this->img_url = $img_url;
    return $this;
}

/**
 * @return the string
 */
public function getDepartment() {
    return $this->department;
}

/**
 * @param string $department
 */
public function setDepartment($department) {
    $this->department = $department;
    return $this;
}

/**
 * @return the string
 */
public function getEmailAddress() {
    return $this->email_address;
}

/**
 * @param string $email_address
 */
public function setEmailAddress($email_address) {
    $this->email_address = $email_address;
    return $this;
}

/**
 * @return the boolean
 */
public function getVerified() {
    return $this->verified;
}

/**
 * @param boolean $verified
 */
public function setVerified($verfied) {
    $this->verified = $verfied;
    return $this;
}

}

现在，当我从 Application 模块的 IndexController 对上述实体进行持久操作时，它工作正常。但是当我在同一个 IndexController 中使用同一个对象映射器进行查找操作时，它给出了映射异常。

以下是我的做法：

$objectManager = $this->getServiceLocator()->get('Doctrine\ORM\EntityManager');
$objectManager->persist($user);
$objectManager->flush();
$user = $objectManager->find('User', $uniqueID);

谁能帮我解决这个问题？

问候。

Answer 1

你的实体不是User，而是Application\Entity\User。所以替换这一行：

$user = $objectManager->find('User', $uniqueID);

有了这个：

$user = $objectManager->find('Application\Entity\User', $uniqueID);
