这是我的粘贴：

上面产生了错误：

Fatal error: method_exists(): The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "Proxies\JStoutMainBundleEntityLocationProxy" of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide a __autoload() function to load the class definition in /www/jstout/vendor/doctrine/lib/Doctrine/ORM/UnitOfWork.php on line 2266 Call Stack: 0.0001 622816 1. {main}() /www/jstout/web/app_dev.php:0 0.0120 1391096 2.

如果删除，错误就会消失：

$vendor->setOwner($user)

这是一个错误还是有一个原因导致我无法将所有者设置为会话对象？

Answer 1

您的 User 对象中有私有属性吗？

在会话中插入对象时会调用php函数serialize，并且私有属性存在问题。您必须将这些私有财产转为受保护。
