Symfony無法加載FieldVote

Question

我從現有實體創建了一個CRUD，一切都很順利，直到我看到結果，我得到以下錯誤：

（使用Symfony 3）

嘗試從命名空間“Symfony \\ Component \\ Security \\ Acl \\ Voter”加載類“FieldVote”。 您是否忘記了另一個命名空間的“use”語句？ 500內部服務器錯誤 - ClassNotFoundException

我不知道該怎么做，因為似乎沒有人遇到這個問題，也沒有找到導致它的原因。

無論如何，這是我的實體和我的控制器的片段：

在代碼中沒有提到投票或任何內容，所以我不知道加載FieldVote需要什么，或者是什么阻止它加載它。 有沒有人有想法？ 我必須確切地說，如果我繼續執行任務/新任務，或任務/ {id}或其他什么，它的工作完全正常。

先感謝您

Answer 1

對我來說，看起來像是一個symfony核心bug。 分支3中的https://github.com/symfony/symfony/tree/master/src/Symfony/Component/Security中沒有Acl目錄。*

實際上，這個目錄在2.7中被刪除了，所以沒有組件2.8應該使用它。 也許你應該向SensioLabs報告。

要擺脫這個錯誤，您可以避免使用@Security Annotation，而是使用安全服務並在控制器內部測試授權：

if (false === $this->get('security.authorization_checker')->isGranted('ROLE_RECRUTEUR')) {
    ....
}
