Php 基本登录和重定向系统Symfony3

我是Symfony的初学者，在我的学习过程中，我必须用传统的登录表单制作一个身份验证系统

我有3个实体：使用者、受体和成分。我只想在连接后使用User登录RecetteController和IngredientController，然后检索登录的用户。还可以在用户未登录时重定向到/login url

在阅读了大量教程（包括）后，我无法让它工作。当我登录时，我总是返回同一页面，而我在我的security.yml中设置了一个

默认\u target\u path:admin\u recette\u new

，我不知道为什么

这是我的档案：
