我正在使用this教程來學習Spring安全性的基礎知識，我目前已經到達this頁面（使用自定義數據庫實現和JSF 2.0的Spring Security 3.1身份驗證）。問題是，即使我已經完全按照他們的博客上所寫的內容複製了所有內容，但如果在嘗試登錄時檢查了「記住我」，我仍然會收到NullPointerException。正如我所見，它是由「LoginBean」中的變量「userDetailsService」引起的。我得到：在Spring Bean上記住我的NullPointerException

你可以發佈你的代碼嗎？ – Adarsh
如果您願意，鏈接中還有更多詳細信息。謝謝。 –
我不知道與Spring相關的東西，但你有沒有嘗試刪除「= null」userDetailsService – Adarsh
