orm - 使用 JMSSerialize 序列化遵循 SimplifiedYamlDriver 约定的 Doctrine2 实体

Question

symfony 赞助的项目\Doctrine\ORM\Mapping\Driver\SimplifiedYamlDriver 在我的项目中非常有用，它可以使实体文件名保持简洁。但是，JMSSerialize 假定每个实体的命名约定是完全限定的 namespace 。在 Doctrine2 配置中使用\Doctrine\ORM\Mapping\Driver\SimplifiedYamlDriver 时，情况并非如此。

( http://docs.doctrine-project.org/en/latest/reference/yaml-mapping.html )

<?php
$namespaces = array(
  '/path/to/files1' => 'MyProject\Entities',
  '/path/to/files2' => 'OtherProject\Entities'
);
$driver = new \Doctrine\ORM\Mapping\Driver\SimplifiedYamlDriver($namespaces);

根据文档:文件名被缩短，“MyProject\Entities\User”将变成 User.orm.yml

但 JMSSerialzer 正在 $myDir 寻找 YAML 文件。 '/MyProject.Entities.User.yml'

(参见:http://jmsyst.com/libs/serializer/master/configuration#configuring-metadata-locations)

问题:有没有办法覆盖 JMSSerialize 查找的元数据文件名？我已经在使用 addMetadataDir() 来指定它的位置

注意:这不是 Symfony2 项目

您是否使用了 addMetadataDir 的第二个参数？

来自JMS\Serializer\SerializerBuilder.php:

/**
 * Adds a directory where the serializer will look for class metadata.
 *
 * The namespace prefix will make the names of the actual metadata files a bit shorter. For example, let's assume
 * that you have a directory where you only store metadata files for the ``MyApplication\Entity`` namespace.
 *
 * If you use an empty prefix, your metadata files would need to look like:
 *
 * ``my-dir/MyApplication.Entity.SomeObject.yml``
 * ``my-dir/MyApplication.Entity.OtherObject.xml``
 *
 * If you use ``MyApplication\Entity`` as prefix, your metadata files would need to look like:
 *
 * ``my-dir/SomeObject.yml``
 * ``my-dir/OtherObject.yml``
 *
 * Please keep in mind that you currently may only have one directory per namespace prefix.
 *
 * @param string $dir The directory where metadata files are located.
 * @param string $namespacePrefix An optional prefix if you only store metadata for specific namespaces in this directory.
 *
 * @return SerializerBuilder
 *
 * @throws InvalidArgumentException When a directory does not exist
 * @throws InvalidArgumentException When a directory has already been registered
 */
public function addMetadataDir($dir, $namespacePrefix = '')
{
    // ...
}

看来，如果指定第二个参数，就可以实现你想要的。
