HTTP狀態400 - 錯誤的請求
類型狀態報告
說明服務器無法或不願處理由於某些被認爲是客戶端錯誤的請求（例如，格式錯誤的請求語法，無效請求消息成幀，或欺騙性請求路由）。
GenderMap是一個可以在屏幕上顯示模型的地圖。關鍵是性別類，價值是性別描述。用戶將選擇一個性別，該性別將引用性別表中的ID。

我認爲action =「registerStaff」不指向方法 –
@ Ali.Mojtehedy Nope。錯誤的URL返回404，但OP得到了400。 – BalusC
HTTP 400可能由於錯誤的請求有效內容對象而發生。在你的情況下，員工註冊bean。在這個類中你定義了一個類型爲Gender的變量性別，但我想在你的jsp中你只需提交一個String？ – mrkernelpanic
