Question

当我想打开一个简单的页面时，我遇到了错误。这是完整的错误：

ContextErrorException：Catchable Fatal Error：类__PHP_Incomplete_Class的对象无法在/Applications/mampstack-5.4.20-0/apache2/htdocs/engelsvandenbroecke/vendor/symfony/symfony/src/Symfony/Component/Security中转换为字符串/Core/Authentication/Token/AbstractToken.php第70行

我在symfony项目中所做的是：

从数据库生成实体
编辑用户实体以确保安全
编辑security.yml
添加了两个datafixtures

这是我的用户实体类：

<?php

帮助我在浏览器中清除缓存/ Cookie。（在浏览器会话中存储了旧版本的用户实体）。

Answer 2

此错误通常意味着您尝试反序列化对象而不加载该对象的类。所以你应该以某种方式定义这个类（例如包含它的文件），然后反序列化它。
