软件工程课程设计|毕业设计之蛋糕商城系统代码-基于javaweb的蛋糕商城系统-基于jsp的商品销售平台代码
前言
本次文章主要是介绍蛋糕商城系统的功能，系统分为两个角色，管理员，用户
一、系统功能
1.1 开发环境
开发语言：Java技术：JavaWeb【Servlet】数据库：MySQL架构：B/S源码类型： Web编译工具：Idea其他：jdk1.8、Tomcat9.0 、Navicat
1.2 管理员功能
登录，用户管理，商品类目管理，商品管理，节日管理，订单管理，发货
1.3 用户功能
注册，登录，修改密码，输入收货信息，搜索，查看热销商品，查看新品加入购物车，提交订，收货
二、部分功能展示
☀️首页☀️
☀️商品展示☀️
☀️项目结构展示☀️
三、部分代码设计
3.1.商品推荐
@WebServlet(name = "admin_goods_list",urlPatterns = "/admin/goods_list")
public class AdminGoodsListServlet extends HttpServlet {
private GoodsService gService = new GoodsService();
/**
* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
*/
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
int type = 0;//推荐类型
if(request.getParameter("type") != null) {
type=Integer.parseInt(request.getParameter("type") ) ;
}
int pageNumber = 1;
if(request.getParameter("pageNumber") != null) {
try {
pageNumber=Integer.parseInt(request.getParameter("pageNumber") ) ;
}
catch (Exception e)
{
}
}
if(pageNumber=p.getTotalPage()+1)
{
p = gService.getGoodsRecommendPage(type, pageNumber);
}
}
request.setAttribute("p", p);
request.setAttribute("type", type);
request.getRequestDispatcher("/admin/goods_list.jsp").forward(request, response);
}
3.2.商品推荐
@WebServlet("/admin/goods_add")
public class AdminGoodsAddServlet extends HttpServlet {
private GoodsService gService = new GoodsService();
/**
* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
*/
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
DiskFileItemFactory factory=new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
try {
List list = upload.parseRequest(request);
Goods g = new Goods();
for(FileItem item:list) {
if(item.isFormField()) {
switch(item.getFieldName()) {
case "name":
g.setName(item.getString("utf-8"));
break;
case "price":
g.setPrice(Integer.parseInt(item.getString("utf-8")));
break;
case "intro":
g.setIntro(item.getString("utf-8"));
break;
case "stock":
g.setStock(Integer.parseInt(item.getString("utf-8")));
break;
case "typeid":
g.setTypeid(Integer.parseInt(item.getString("utf-8")));
break;
}
}else {
if(item.getInputStream().available()0 ) {
out.write(buffer);
}
in.close();
out.close();
item.delete();
switch(item.getFieldName()) {
case "cover":
g.setCover("/picture"+fileName);
break;
case "image1":
g.setImage1("/picture"+fileName);
break;
case "image2":
g.setImage2("/picture"+fileName);
break;
}
}
}
gService.insert(g);
request.getRequestDispatcher("/admin/goods_list").forward(request, response);
} catch (FileUploadException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
/**
* @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
doGet(request, response);
}
}
3.3.编辑商品
@WebServlet("/admin/goods_edit")
public class AdminGoodsEditServlet extends HttpServlet {
private GoodsService gService = new GoodsService();
/**
* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
*/
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
DiskFileItemFactory factory=new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
try {
List list = upload.parseRequest(request);
Goods g = new Goods();
int pageNo =1;
int type=0;
for(FileItem item:list) {
if(item.isFormField()) {
switch(item.getFieldName()) {
case "id":
g.setId(Integer.parseInt(item.getString("utf-8")));
break;
case "name":
g.setName(item.getString("utf-8"));
break;
case "price":
g.setPrice(Float.parseFloat(item.getString("utf-8")));
break;
case "intro":
g.setIntro(item.getString("utf-8"));
break;
case "cover":
g.setCover(item.getString("utf-8"));
break;
case "image1":
g.setImage1(item.getString("utf-8"));
break;
case "image2":
g.setImage2(item.getString("utf-8"));
break;
case "stock":
g.setStock(Integer.parseInt(item.getString("utf-8")));
break;
case "typeid":
g.setTypeid(Integer.parseInt(item.getString("utf-8")));
break;
case "pageNo":
pageNo=Integer.parseInt(item.getString("utf-8"));
break;
case "type":
type = Integer.parseInt(item.getString("utf-8"));
break;
}
}else {
if(item.getInputStream().available()0 ) {
out.write(buffer);
}
in.close();
out.close();
item.delete();
switch(item.getFieldName()) {
case "cover":
g.setCover("/picture"+fileName);
break;
case "image1":
g.setImage1("/picture"+fileName);
break;
case "image2":
g.setImage2("/picture"+fileName);
break;
}
}
}
gService.update(g);
request.getRequestDispatcher("/admin/goods_list?pageNo="+pageNo+"&type="+type).forward(request, response);
} catch (FileUploadException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
/**
* @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
doGet(request, response);
}
}
