Java畢業(yè)設計實戰(zhàn)之共享租車信息管理系統(tǒng)的實現(xiàn)
更新時間：2022年02月05日 13:25:22 作者：OldWinePot
這是一個使用了java+Jsp+Servlet+Jdbc+Mysql開發(fā)的共享租車信息管理系統(tǒng)，是一個畢業(yè)設計的實戰(zhàn)練習，具有租車管理該有的所有功能，感興趣的朋友快來看看吧
基于servlet+jsp+jdbc的后臺管理系統(tǒng)，包含5個模塊：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，均能實現(xiàn)增刪查改。
運行環(huán)境：
jdk8+tomcat8.5+mysql5.7+Eclipse
項目技術：
servlet+jsp+jdbc+easyui+jquery
