這篇文章給大家分享的是有關使用JSP實現簡單的用戶登錄注冊頁面示的方法的內容。小編覺得挺實用的，因此分享給大家做個參考。一起跟隨小編過來看看吧。
實驗要求：
將實驗2中的系統用戶登錄和注冊頁面改為JSP頁面，并部署自己的Web應用于Tomcat服務器中
具體要求：
完成登錄JSP頁面設計和注冊頁面設計
在登錄頁面表單中使用request對象獲取用戶信息，建立新的JSP頁面完成登錄驗證（用戶名和密碼自己指定即可）。
驗證結果顯示（如登錄成功/用戶名密碼錯誤，可以使用JavaScript，也可以使用新的JSP頁面）。
在注冊頁面表單中使用request對象獲取用戶注冊信息（注冊項目由自己指定），在新的JSP頁面顯示用戶注冊信息，并提示注冊成功。
