java无法在spring security with spring boot中阻止同一用户的多个并发登录

Question

** 在这里，我编辑了我的代码，以查看我目前正在为此目的使用内存中身份验证

这是我的安全配置文件，我想要实现的是一个用户没有并发会话。 使用此代码，我可以在多个选项卡上与同一用户登录。 即使用户有活动会话 有人能帮我吗。我是Spring security的新手 提前谢谢**

简单的检查可以帮助您在这里找到类似的question

很可能您没有在登录的User类中实现/重写正确的hashCode和equals方法

您必须这样做，这取决于您在逻辑上如何确定所谓的“相同”用户：

 public class User implements UserDetails, Serializable {
    private static final long serialVersionUID = 1L;

    // ...

    @Override
    public boolean equals(Object obj) {
        if (obj instanceof User) {
          return username.equals( ((User) obj).getUsername() );
        }
        return false;
    }

    @Override
    public int hashCode() {
        return username != null ? username.hashCode() : 0;
    }
}
