每当我尝试运行此代码时，我都会收到一些错误消息，指出 userDetailsService 没有 bean 初始化。现在 userDetailsService 指的是一个接口 org.springframework.security.core.userdetails.UserDetailsService。另外我不确定它如何与数据库交互以进行用户 ID 和密码验证。
这是我收到的错误消息

【问题讨论】：
你能附上你的 web.xml 吗？ @VladimírSchäfer : 请同时查看 web.xml 文件，如果有问题请告诉我。 【参考方案1】：由于您尝试实例化接口，这就是您收到错误的原因。 尝试通过实现 UserDetailsService 接口创建一个类，然后尝试实例化该类对象。
【讨论】：
以上是关于记住我由 Spring Security 提供的功能的主要内容，如果未能解决你的问题，请参考以下文章
Spring WebFlux + Security - 我们有“记住我”功能吗？
