Java畢業(yè)設(shè)計(jì)實(shí)戰(zhàn)之共享租車信息管理系統(tǒng)的實(shí)現(xiàn)

更新時(shí)間：2022年02月05日 13:25:22 作者：OldWinePot

這是一個(gè)使用了java+Jsp+Servlet+Jdbc+Mysql開(kāi)發(fā)的共享租車信息管理系統(tǒng)，是一個(gè)畢業(yè)設(shè)計(jì)的實(shí)戰(zhàn)練習(xí)，具有租車管理該有的所有功能，感興趣的朋友快來(lái)看看吧

基于servlet+jsp+jdbc的后臺(tái)管理系統(tǒng)，包含5個(gè)模塊：汽車賬戶部管理、租車賬戶部管理、汽車信息管理表、租車記錄表、租車租聘表。功能完整，均能實(shí)現(xiàn)增刪查改。

運(yùn)行環(huán)境：

jdk8+tomcat8.5+mysql5.7+Eclipse

項(xiàng)目技術(shù)：

servlet+jsp+jdbc+easyui+jquery
