我正在关注此视频中的教程：https ://www.youtube.com/watch?v=X80nJ5T7YpE&list=PLqq-6Pq4lTTYTEooakHchTGglSvkZAjnE&index=12
我的代码处于 7:30 标记的状态。无论出于何种原因，我似乎无法让SecurityConfigurer.java该类识别我的自定义 UserDetailsService 类，称为MyUserDetailsService.java.
预期的行为是，当我转到我在HelloResource.Java课堂上指定的 /hello 端点时，应该会生成一个登录页面。我应该能够使用该loadUserByUsername方法的硬编码返回用户值以及用户名和密码“foo”登录到网页。
不管我做了什么改变，似乎总是loadUserByUsername没有调用该方法（我已经用断点/打印语句证明了这一点）。这让我相信可能存在一些组件扫描问题，但我还没有看到任何工作！
我已经在这些链接上尝试过解决方案： One、Two、Three以及更多。这是我的相关文件：
