這篇文章主要介紹了使用JSP實(shí)現(xiàn)簡(jiǎn)單的用戶登錄注冊(cè)頁(yè)面示例代碼解析，文中通過(guò)示例代碼介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值，需要的朋友們下面隨著小編來(lái)一起學(xué)習(xí)學(xué)習(xí)吧

實(shí)驗(yàn)要求：

將實(shí)驗(yàn)2中的系統(tǒng)用戶登錄和注冊(cè)頁(yè)面改為JSP頁(yè)面，并部署自己的Web應(yīng)用于Tomcat服務(wù)器中

具體要求：

完成登錄JSP頁(yè)面設(shè)計(jì)和注冊(cè)頁(yè)面設(shè)計(jì)

在登錄頁(yè)面表單中使用request對(duì)象獲取用戶信息，建立新的JSP頁(yè)面完成登錄驗(yàn)證（用戶名和密碼自己指定即可）。

驗(yàn)證結(jié)果顯示（如登錄成功/用戶名密碼錯(cuò)誤，可以使用JavaScript，也可以使用新的JSP頁(yè)面）。

在注冊(cè)頁(yè)面表單中使用request對(duì)象獲取用戶注冊(cè)信息（注冊(cè)項(xiàng)目由自己指定），在新的JSP頁(yè)面顯示用戶注冊(cè)信息，并提示注冊(cè)成功。
