我最近一直在用这个Doctrine2 风格的 Neo4j 包装器进行测试。虽然以前从未使用过 Doctrine，但我已经从 Github 页面和 Doctrine 文档中删除了一些很好的示例，并且似乎无法通过某个点。我提取了 Neo4j-PHP-OGM 库，使用 Composer 下载了 Doctrine2，并将 EntityManager 程序化（用于测试）包含在bootstrap.php.

/bootstrap.php

require __DIR__ . '/vendor/autoload.php';

require __DIR__ . '/lib/HireVoice/Neo4j/Annotation/Entity.php';
require __DIR__ . '/lib/HireVoice/Neo4j/Annotation/Auto.php';
require __DIR__ . '/lib/HireVoice/Neo4j/Annotation/Property.php';
require __DIR__ . '/lib/HireVoice/Neo4j/Annotation/Index.php';
require __DIR__ . '/lib/HireVoice/Neo4j/Annotation/ManyToOne.php';
require __DIR__ . '/lib/HireVoice/Neo4j/Annotation/ManyToMany.php';

$em = new HireVoice\Neo4j\EntityManager(array(
     'transport' => 'curl', // or 'stream'
     'host' => 'localhost',
     'port' => 7474,
    // 'username' => null,
    // 'password' => null,
    // 'proxy_dir' => '/tmp',
    // 'debug' => true, // Force proxy regeneration on each request
    // 'annotation_reader' => ... // Should be a cached instance of the doctrine annotation reader in production
));

/用户.php

namespace Entity;

use HireVoice\Neo4j\Annotation as OGM;
use Doctrine\Common\Collections\ArrayCollection;

/**
 * @OGM\Entity
 */
class User
{
    /**
     * @OGM\Auto
     */
    protected $id;

    /**
     * @OGM\Property
     * @OGM\Index
     */
    protected $fullName;

    function setFullName($fullname){
        $this->fullname = $fullname;
    }
}

/保存.php

require 'bootstrap.php';
require 'User.php';

$repo = $em->getRepository('Entity\\User');

$jane = new User;
$jane->setFullName('Jane Doe');

$em->persist($jane);
$em->flush();

在生产中，我将自动加载实体类，现在我只需要它们。在浏览器中加载save.php时，它会引发此错误：

Fatal error: Class 'User' not found in C:\htdocs\neo4j-php\ogm\save.php on line 7

我不确定为什么，因为User.php在bootstrap.php. 关于为什么的任何建议？提前致谢。

您的问题似乎与 PHP 命名空间有关，而不是与库有关。

require 'bootstrap.php';
require 'User.php'; // Are you certain the path is correct?

$repo = $em->getRepository('Entity\\User');

$jane = new Entity\User; // Need to specify the full class path unless you import it locally
$jane->setFullName('Jane Doe');

$em->persist($jane);
$em->flush();
