讀萬卷書不如行萬里路，只學書上的理論是遠遠不夠的，只有在實戰(zhàn)中才能獲得能力的提升，本篇文章手把手帶你用Java實現(xiàn)一個家居購物商城系統(tǒng),大家可以在過程中查缺補漏，提升水平

一、項目簡述

功能： Java Web精品項目源碼，家居商城分類展示，商品展示，商品下單，購物車，個人中心，后臺管理，用戶管理，商品管理，分類管理等等。

二、項目運行

環(huán)境配置： Jdk1.8 + Tomcat8.5 + mysql + Eclispe (IntelliJ IDEA,Eclispe,MyEclispe,Sts 都支持)

項目技術： Jdbc+ Servlert + html+ css + JavaScript + JQuery + Ajax + Fileupload

打開訂單列表頁面代碼：

@Controller
@RequestMapping("/order")
public class OrderController {
    @Autowired
    private OrderService orderService;
 
    /**
     * 打開訂單列表頁面
     *
     * @return
     */
    @RequestMapping("/toList.html")
    public String toOrderList() {
        return "mall/order/list";
    }
 
    /**
     * 查詢用戶訂單列表
     *
     * @param request
     * @return
     */
    @RequestMapping("/list.do")
    @ResponseBody
    public ResultBean<List<Order>> listData(HttpServletRequest request) {
        List<Order> orders = orderService.findUserOrder(request);
        return new ResultBean<>(orders);
    }
 
    /**
     * 查詢訂單詳情
     *
     * @param orderId
     * @return
     */
    @RequestMapping("/getDetail.do")
    @ResponseBody
    public ResultBean<List<OrderItem>> getDetail(int orderId) {
        List<OrderItem> orderItems = orderService.findItems(orderId);
        return new ResultBean<>(orderItems);
    }
 
    /**
     * 提交訂單
     *
     * @param name
     * @param phone
     * @param addr
     * @param request
     * @param response
     */
    @RequestMapping("/submit.do")

                       String phone,
                       String addr,
                       HttpServletRequest request,
                       HttpServletResponse response) throws Exception {
        orderService.submit(name, phone, addr, request, response);
    }
 
    /**
     * 支付方法
     *
     * @param orderId
     */

     * @param orderId
     * @param response
     * @return
     * @throws IOException
