項目介紹

基于B2C的網上拍賣系統主要用于幫助人們應用互聯網方便快捷買到自己所中意的商品，并參與到秒殺與競拍當中。

主要功能包括：
1.前臺模塊
(1)普通用戶登錄/注冊。
(2)分類查看商品(普通商品與促銷商品)
(3)查看商品詳細信息
(4)查看秒殺商品
(5)查看競拍商品
(6)將商品加入購物車
(7)購買，結算功能
(8)留言
2.后臺模塊
(1)修改密碼
(2)商品管理:
-- 編輯/刪除
-- 設置/取消促銷
(3)秒殺商品：設置/取消秒殺
(4)競拍商品：設置/取消競拍
(5)訂單管理：查看訂單
(6)留言管理：查看/刪除留言

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.是否Maven項目: 否；查看源碼目錄中是否包含pom.xml；若包含，則為maven項目，否則為非maven項目?
6.數據庫：MySql 5.7版本；

技術棧

1. 后端：Servlet

2. 前端：JSP+bootstrap+jQuery

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. 將項目中resources/ioc/dao.js配置文件中的數據庫配置改為自己的配置;

3. 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，配置tomcat，然后運行；

4.項目訪問路徑:

前臺：http://localhost:8080/sale

后臺：http://localhost:8080/sale/user/adminlogin
