我从现有实体创建了一个CRUD，一切都很顺利，直到我看到结果，我收到以下错误：
（使用Symfony 3）
尝试从命名空间“Symfony \ Component \ Security \ Acl \ Voter”加载类“FieldVote”。 您是否忘记了另一个命名空间的“use”语句？ 500内部服务器错误 - ClassNotFoundException
我不知道如何处理这个问题，因为似乎没有人遇到过这个问题，也没有找到导致问题的原因。
无论如何，这是我的实体和我的控制器的片段：

代码中没有提及投票或任何内容，因此我不知道加载FieldVote需要什么，或者是什么阻止它加载它。 有没有人有想法？ 我必须确切地说，如果我继续执行任务/新任务，或任务/ {id}或其他什么，它的工作完全正常。
提前谢谢
答案 0 :(得分：0)
对我来说完全看起来像是一个symfony核心bug。分支3中的https://github.com/symfony/symfony/tree/master/src/Symfony/Component/Security中没有Acl目录。*
实际上，这个目录在2.7中被删除了，所以没有组件2.8应该使用它。也许你应该把它报告给SensioLabs。
要摆脱这个错误，您可以避免使用@Security Annotation，而是使用安全服务并在控制器内部测试授权：
if (false === $this->get('security.authorization_checker')->isGranted('ROLE_RECRUTEUR')) {
....
}
