原则注释加载器失败 - Doctrine annotation loader fails

Doctrine annotation loader fails

本文关键字：失败加载注释原则 | 更新日期: 2023-09-27

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

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line

$type = new Type;

手动触发自动加载器，它工作:

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

我看到AnnotationRegistry不使用自动加载器，它试图使用一些自己的自动加载器。它看起来很丑，我要怎么做才能修好它?

好吧，我自己回答我的问题。我必须在自动加载器文件的某个地方注册注释:

'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序列化器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。
