主要功能包括：
1.前台模块
(1)普通用户登录/注册。
(2)分类查看商品(普通商品与促销商品)
(3)查看商品详细信息
(4)查看秒杀商品
(5)查看竞拍商品
(6)将商品加入购物车
(7)购买，结算功能
(8)留言
2.后台模块
(1)修改密码
(2)商品管理:
编辑/删除
设置/取消促销
(3)秒杀商品：设置/取消秒杀
(4)竞拍商品：设置/取消竞拍
(5)订单管理：查看订单
(6)留言管理：查看/删除留言
环境需要
1.运行环境：最好是java jdk 1.8，我们在这个平台上运行的。其他版本理论上也可以。
2.IDE环境：IDEA，Eclipse,Myeclipse都可以。推荐IDEA;
3.tomcat环境：Tomcat 7.x,8.x,9.x版本均可
4.硬件环境：windows 7/8/10 1G内存以上；或者 Mac OS；
5.是否Maven项目: 否；查看源码目录中是否包含pom.xml；若包含，则为maven项目，否则为非maven项目
6.数据库：MySql 5.7版本；
技术栈
1. 后端：Servlet
2. 前端：JSP+bootstrap+jQuery
使用说明
1. 使用Navicat或者其它工具，在mysql中创建对应名称的数据库，并导入项目的sql文件；
2. 将项目中resources/ioc/dao.js配置文件中的数据库配置改为自己的配置;
3. 使用IDEA/Eclipse/MyEclipse导入项目，Eclipse/MyEclipse导入时，若为maven项目请选择maven;若为maven项目，导入成功后请执行maven clean;maven install命令，配置tomcat，然后运行；
4.项目访问路径:
前台：http://localhost:8080/sale
后台：http://localhost:8080/sale/user/adminlogin
用户管理层：
public class UserServlet extends BaseBackServlet {
@Override
public String add(HttpServletRequest request, HttpServletResponse response, Page page) {
System.out.println("调用了 UserServlet add方法");
return null;
}
@Override
public String delete(HttpServletRequest request, HttpServletResponse response, Page page) {
System.out.println("调用了 UserServlet delete方法");
int id = Integer.parseInt(request.getParameter("id"));
userDAO.delete(id);
return "@admin_user_list";
}
@Override
public String update(HttpServletRequest request, HttpServletResponse response, Page page) {
System.out.println("调用了 UserServlet update方法");
Map<String, String> params = new HashMap<>();
InputStream is = super.parseUpload(request, params);
System.out.println(params);
int id = Integer.parseInt(params.get("id"));
String password = params.get("password");
User user = userDAO.get(id);
user.setPassword(password);
userDAO.update(user);
return "@admin_user_list";
}
@Override
public String edit(HttpServletRequest request, HttpServletResponse response, Page page) {
System.out.println("调用了 UserServlet edit方法");
int id = Integer.parseInt(request.getParameter("id"));
User u = userDAO.get(id);
request.setAttribute("u", u);
return "admin/editUser.jsp";
}
@Override
public String list(HttpServletRequest request, HttpServletResponse response, Page page) {
System.out.println("调用了 UserServlet list方法");

int total = userDAO.getTotal();

订单控制层：
public class OrderServlet extends BaseBackServlet {
@Override
public String add(HttpServletRequest request, HttpServletResponse response, Page page) {
return null;
}
@Override
public String delete(HttpServletRequest request, HttpServletResponse response, Page page) {
return null;
}
@Override
public String update(HttpServletRequest request, HttpServletResponse response, Page page) {
return null;
}
@Override
public String edit(HttpServletRequest request, HttpServletResponse response, Page page) {
return null;
}
public String delivery(HttpServletRequest request, HttpServletResponse response, Page page) {
System.out.println("调用了 OrderServlet delivery方法");
int id = Integer.parseInt(request.getParameter("id"));
Order o = orderDAO.get(id);
o.setDeliveryDate(new Date());
o.setStatus(OrderDAO.waitConfirm);
orderDAO.update(o);
return "@admin_order_list";
}
@Override
public String list(HttpServletRequest request, HttpServletResponse response, Page page) {
System.out.println("调用了 OrderServlet list方法");
// 对订单对应的订单项进行初始化
List<Order> os = orderDAO.list(page.getStart(), page.getCount());
orderItemDAO.fill(os);
int total = orderDAO.getTotal();
page.setTotal(total);
request.setAttribute("os", os);
request.setAttribute("page", page);
return "admin/listOrder.jsp";
}
}
商品管理控制层：
public class CategoryServlet extends BaseBackServlet {
@Override

Map<String,String> params = new HashMap<>();
InputStream is = super.parseUpload(request, params);

){
byte[] b = new byte[1024 * 1024];
int length = 0;
while(-1 != (length = is.read(b))){
fos.write(b, 0, length);
}
fos.flush();
//通过以下代码，将文件保存为jsp格式
BufferedImage img = ImageUtil.change2jpg(file);
ImageIO.write(img, "jpg", file);
}
}
} catch (IOException e) {
e.printStackTrace();
}
return "@admin_category_list";

@Override
public String delete(HttpServletRequest request, HttpServletResponse response, Page page) {
System.out.println("调用了category delete方法");
