想了解Java 实战项目锤炼之在线购书商城系统的实现流程的相关内容吗,qq_1334611189在本文为您仔细讲解Java 在线购书商城系统的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:Java,在线购书,Java,商城系统,下面大家一起来学习吧。

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;
 
    /**
     * 查询某一本书籍详情
     *
     * @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<BookInfo> 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);
        Collections.shuffle(recommendBookList);
        model.addAttribute("bookInfo", bookInfo);
        model.addAttribute("bookDesc", bookDesc);
        model.addAttribute("recommendBookList", recommendBookList);
        return "book_info";
    }
 
 
    /**
     * 通过关键字和书籍分类搜索书籍列表
     *
     * @param keywords
     * @return
     */
    @RequestMapping("/list")
    public String bookSearchList(@RequestParam(defaultValue = "", required = false) String keywords,
                                 @RequestParam(defaultValue = "0", required = false) int cateId,//分类Id,默认为0,即不按照分类Id查
                                 @RequestParam(defaultValue = "1", required = false) int page,
                                 @RequestParam(defaultValue = "6", required = false) int pageSize,
                                 Model model) {
        keywords = keywords.trim();
        PageInfo<BookInfo> bookPageInfo = bookInfoService.findBookListByCondition(keywords, cateId, page, pageSize,0);//storeId为0,不按照商店Id查询
 
        model.addAttribute("bookPageInfo", bookPageInfo);
 
        model.addAttribute("keywords", keywords);
 
        model.addAttribute("cateId", cateId);
