環境需要

1.運行環境：最好是java jdk 1.8，我們在這個平臺上運行的。其他版本理論上也可以。
2.IDE環境：IDEA，Eclipse,Myeclipse都可以。推薦IDEA;
3.tomcat環境：Tomcat 7.x,8.x,9.x版本均可
4.硬件環境：windows 7/8/10 1G內存以上；或者 Mac OS；?
5.數據庫：MySql 5.7版本；
6.是否Maven項目：否；

技術棧

1. 后端：Servlet
2. 前端：JSP+CSS+JavaScript+jQuery+Bootstrap

使用說明

1. 使用Navicat或者其它工具，在mysql中創建對應名稱的數據庫，并導入項目的sql文件；
2. 使用IDEA/Eclipse/MyEclipse導入項目，Eclipse/MyEclipse導入時，若為maven項目請選擇maven;
若為maven項目，導入成功后請執行maven clean;maven install命令，然后運行；
3. 將項目中src/utils/DBUtil.java配置文件中的數據庫配置改為自己的配置;
4. 運行項目，輸入localhost:8080/jsp_petmall 登錄 注：Tomcat中配置路徑必須為jsp_petmall，否則會出問題；
用戶賬號/密碼： user/123456
管理員賬號/密碼：admin/admin
