我正在尝试运行 JMSSerializer。我的简单代码

use JMS\Serializer\Annotation\Type;

class Comment
{
    private $msg;

    public function __construct($msg)
    {
        $this->msg = $msg;
    }
}

class Person
{
    /**
     * @Type("array<Comment>")
     */
    private $commentList;

    public function addComment(Comment $comment)
    {
        $this->commentList[] = $comment;
    }
}

$type = new Type;
$serializer = JMS\Serializer\SerializerBuilder::create()->build();

$data = new Person();
$data->addComment(new Comment('hey'));

var_dump($serializer->serialize($data, 'json'));

失败了

PHP Fatal error:  Uncaught exception 'Doctrine\Common\Annotations\AnnotationException' with message '[Semantical Error] The annotation "@JMS\Serializer\Annotation\Type" in property Person::$commentList does not exist, or could not be auto-loaded.' in xxx.php:52

好的,但是如果我添加行

$type = new Type;

要手动触发自动加载器,它可以工作:

string(32) "{"comment_list":[{"msg":"hey"}]}"

正如我所见,AnnotationRegistry 不使用自动加载器,它尝试使用一些自己的自动加载器。它看起来很丑,我该怎么做才能修复它?

好的,我自己回答我的问题。我必须在自动加载器文件的某处注册注释:

\Doctrine\Common\Annotations\AnnotationRegistry::registerAutoloadNamespace(
    'JMS\Serializer\Annotation', __DIR__.'/vendor/jms/serializer/src'
);

其他方式:http ://docs.doctrine-project.org/projects/doctrine-common/en/latest/reference/annotations.html#registering-annotations

独立 JMS 序列化程序库的完整配置示例可以是:

<?php
namespace iMSCP\Service;
use JMS\Serializer\Serializer;
use JMS\Serializer\SerializerBuilder;
use Doctrine\Common\Annotations\AnnotationRegistry;
use iMSCP_Registry as Registry;

/**
 * Class SerializerServiceFactory
 * @package iMSCP\Service
 */
class SerializerServiceFactory
{
    /**
     * @var Serializer
     */
    static $serialiszer;

    public static function create()
    {
        if (static::$serialiszer === null) {
            $config = Registry::get('config');
            AnnotationRegistry::registerAutoloadNamespace(
                'JMS\Serializer\Annotation', $config['CACHE_DATA_DIR'] . '/packages/vendor/jms/serializer/src'
            );
            static::$serialiszer = SerializerBuilder::create()
                ->setCacheDir(CACHE_PATH . '/serializer')
                ->setDebug($config['DEVMODE'])
                ->build();
        }

        return static::$serialiszer;
    }
}

在这里,我使用 Doctrine 提供的 Annotation 注册表注册JMS\Serializer\Annotation命名空间。完成后,一切都按预期工作。
