Java项目:在线购书商城系统(java+jsp+mysql+servlet+ajax)

一、项目简述

功能：一个基于JavaWeb的网上书店的设计与实现，归纳 出了几个模块，首先是登录注册模块，图书查找模块，购 物车模块，订单模块，个人中心模块，用户管理模块，图 书管理模块等。 该项目是javaJeb技术的实战操作，采用了MVC设计模 式，包括基本的entity, jscript, servlet,以及ajax异步请 求，查询分页，持久化层方法的封装等等，对javaweb技 术的巩固很有帮助，为J2EE的学习打下基础，适用于课程 设计，毕业设计。

二、项目运行

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

项目技术： JSP + Entity+ Servlert + html+ css + JavaScript + JQuery + Ajax + Fileupload 等等。

书信息管理代码:

书信息管理:

@Controller
@RequestMapping("/book")
public class BookInfoController {



    @Autowired
    private IBookInfoService bookInfoService;

    @Autowired
    private BookDescMapper bookDescMapper;

    /**

     *
     * @param bookId
     * @param model
     * @return
     */
    @RequestMapping("/info/{bookId}")
    public String bookInfo(@PathVariable("bookId") Integer bookId, Model model) throws BSException {
        //查询书籍
        BookInfo bookInfo = bookInfoService.findById(bookId);
        //查询书籍推荐列表
        List recommendBookList = bookInfoService.findBookListByCateId(bookInfo.getBookCategoryId(), 1, 5);
        //查询书籍详情
        BookDesc bookDesc = bookDescMapper.selectByPrimaryKey(bookId);
        //增加访问量
        bookInfoService.addLookMount(bookInfo);
