在Symfony 3项目中使用JMS序列化器时遇到一些麻烦。 （我在ubuntu上工作） 当我使用以下代码行反序列化XML波纹管时：
$xmlContent = file_get_contents($filePath);
$order = $this->getContainer()->get('jms_serializer')->deserialize($xmlContent, 'AppBundle\xml\ORDER', 'xml');
我得到了这个对象（这是我的$ order对象的var_dump的结果）：
object(AppBundle\xml\ORDER)#647 (5) {
["version":"AppBundle\xml\ORDER":private]=>
string(3) "1.0"
["type":"AppBundle\xml\ORDER":private]=>
string(8) "standard"
["oRDERHEADER":"AppBundle\xml\ORDER":private]=>
NULL
["oRDERITEMLIST":"AppBundle\xml\ORDER":private]=>
array(0) {
}
["oRDERSUMMARY":"AppBundle\xml\ORDER":private]=>
NULL
}
OrderHeader，OrderItemList和OrderSummary为NULL，而XML则不应该。
XML内容（在文件$ filePath中）：
<?xml version="1.0" encoding="utf-8"?>
<ORDER version="1.0" type="standard" xlmns="http://www.opentrans.org/XMLSchema/1.0">

我指定使用此捆绑包从xsd生成PHP类和YML文件：https://github.com/goetas-webservices/xsd2php
我的 PHP类的相应位置位于： / var / www / symfony / tn / src / AppBundle / xml YML文件位于此处： / var / www / symfony / tn / src / AppBundle / xml / metadata

/var/www/symfony/tn/src/AppBundle/xml/metadata/ORDER.yml的内容

最后，我将 /var/www/symfony/tn/app/config/config.yml 文件的摘录粘贴到此处，与jms序列化程序配置相对应：
jms_serializer:
handlers:
datetime:
default_format: "Y-m-d\\TH:i:sP" # ATOM
default_timezone: "UTC" # defaults to whatever timezone set in php.ini or via date_default_timezone_set
array_collection:
initialize_excluded: false
metadata:
directories:
AppBundle:
namespace_prefix: "AppBundle\\xml"
path: "%kernel.project_dir%/src/AppBundle/xml/metadata"
我认为我描述PHP类的YML文件未加载。为了进行检查，我更新了我的ORDER.yml文件，并将version属性暴露设置为false（请参见下面的波纹管代码），然后在$ order对象的var_dump中继续暴露“版本”字段，如您所见。 / p>
AppBundle\xml\ORDER:
xml_root_name: ORDER
xml_root_namespace: 'http://www.opentrans.org/XMLSchema/1.0'
properties:
version:
expose: false
access_type: public_method
serialized_name: version
accessor:
getter: getVersion
setter: setVersion
xml_attribute: true
type: string
我指定我显然对Web和JMS序列化器文档进行了大量研究，但我仍然坚持：s
