Doctrine注释加载器失败

Question

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,但如果我添加线

$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.它看起来很难看,我该怎么做才能解决它？

好的,我自己回答了我的问题.我必须在autoloader文件中的某处注册注释:

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