Java專案:在線購書商城系統(java+jsp+mysql+servlet+ajax)-有解無憂

一、專案簡述

功能：一個基于JavaWeb的網上書店的設計與實作，歸納出了幾個模塊，首先是登錄注冊模塊，圖書查找模塊，購物車模塊，訂單模塊，個人中心模塊，用戶管理模塊，圖書管理模塊等，該專案是javaJeb技術的實戰操作，采用了MVC設計模式，包括基本的entity, jscript, servlet,以及ajax異步請求，查詢分頁，持久化層方法的封裝等等，對javaweb技術的鞏固很有幫助，為J2EE的學習打下基礎，適用于課程設計，畢業設計，

二、專案運行

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

專案技術： JSP + Entity+ Servlert + html+ css + JavaScript + JQuery + Ajax + Fileupload 等等，

書資訊管理代碼:

書資訊管理:

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



    @Autowired
    private IBookInfoService bookInfoService;

    @Autowired
    private BookDescMapper bookDescMapper;

    /**
     * 查詢某一本書籍詳情
     *
     * @param bookId
     * @param model
     * @return
     */
    @RequestMapping("/info/{bookId}")
    public String bookInfo(@PathVariable("bookId") Integer bookId, Model model) throws BSException {
        //查詢書籍
        BookInfo bookInfo = bookInfoService.findById(bookId);
        //查詢書籍推薦串列
        List<BookInfo> recommendBookList = bookInfoService.findBookListByCateId(bookInfo.getBookCategoryId(), 1, 5);
        //查詢書籍詳情
        BookDesc bookDesc = bookDescMapper.selectByPrimaryKey(bookId);
        //增加訪問量
        bookInfoService.addLookMount(bookInfo);
        Collections.shuffle(recommendBookList);
        model.addAttribute("bookInfo", bookInfo);
        model.addAttribute("bookDesc", bookDesc);
        model.addAttribute("recommendBookList", recommendBookList);
        return "book_info";
    }


    /**
     * 通過關鍵字和書籍分類搜索書籍串列
     *
     * @param keywords
     * @return
     */
    @RequestMapping("/list")
    public String bookSearchList(@RequestParam(defaultValue = "", required = false) String keywords,
                                 @RequestParam(defaultValue = "0", required = false) int cateId,//分類Id，默認為0，即不按照分類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為0，不按照商店Id查詢

        model.addAttribute("bookPageInfo", bookPageInfo);

        model.addAttribute("keywords", keywords);

        model.addAttribute("cateId", cateId);

        return "book_list";

}
