Symfony 5 : 问题 userProvider 不包含来自扩展类的标识符。

Question

我有一个类 "etudiant "从user.问题是当我试图用一个 "etudiant "账户登录退出时，我有这样的消息：你不能从EntityUserProvider刷新一个不包含标识符的用户。用户对象必须通过Doctrine映射的自己的标识符进行序列化。

用户实体 :

错误: 找不到任何解决方案。如何才能解决这个问题。谢谢你了

Answer 1

解决方法是删除实体Etudiant中的覆盖。

   *  @ORM\AttributeOverrides({
 *      @AttributeOverride(name="id",
 *          column=@Column(
 *              name     = "id",
 *              type     = "integer",
 *              length   = 140
 *          )
 *      )
 * })

并从Entity Etudiant中删除methode getId()。
