上面产生错误：

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，错误消失了：

$vendor->setowner($user)

这是错误还是我不能将所有者设置为会话对象的原因？     

解决方法

        您的User对象中是否有私有属性？ 在会话中插入对象时，将调用php函数serialize，并且私有属性存在问题。您必须将这些私有财产进行保护。
