本文實例為大家分享了Spring MVC mybatis實現(xiàn)注冊登錄功能的具體代碼，供大家參考，具體內(nèi)容如下
前期準(zhǔn)備：
如下圖所示，準(zhǔn)備好所需要的包
新建工程，導(dǎo)入所需要的包，在web.xml中配置好所需要的，如下

前端準(zhǔn)備工作
我做的一個簡單的注冊登錄的頁面，在頁面中對表單進(jìn)行了第一層的判斷，然后在后端又寫了第二層驗證。

頁面中對手機(jī)號進(jìn)行了驗證，而且能夠與后臺進(jìn)行交互，判斷數(shù)據(jù)庫中是否已有此手機(jī)號，頁面所需的js文件和css配置會在以下給出，
進(jìn)入正題
數(shù)據(jù)庫中包含用戶手機(jī)號，用戶密碼，以及注冊信息，和生成的唯一識別碼

OK，到這里已經(jīng)基本差不多了，但是這里邊所給的代碼并不完整，為了方便大家相互交流學(xué)習(xí)，這是源碼以及數(shù)據(jù)庫文件，
