后台管理员图书管理代码：

@Controller@RequestMapping("/admin/book")@RequiresPermissions("book-manage")public class AdminBookController {     @Autowired    private IBookInfoService bookInfoService;     @Autowired    private BookDescMapper bookDescMapper;     @Autowired    private IStoreService storeService;     @Value("${image.url.prefix}")    private String urlPrefix;     @RequestMapping("toAddition")    @RequiresPermissions("book-add")    public String toAddition() {        return "admin/book/add";    }     /**     * 添加书籍     *     */    @RequestMapping("/addition")    @RequiresPermissions("book-add")    public String addBook(BookInfo bookInfo, String bookDesc, MultipartFile pictureFile, HttpServletRequest request) throws Exception {         uploadPicture(bookInfo, pictureFile, request);        bookInfoService.saveBook(bookInfo, bookDesc);         return "redirect:/admin/book/list";    }     /**     * 书籍列表     *     */    @RequestMapping(value = "/list")    @RequiresPermissions("book-query")    public String bookList(@RequestParam(defaultValue = "", required = false) String keywords,                           @RequestParam(value = "page", defaultValue = "1", required = false) int page,                           HttpSession session,                           Model model) {        keywords = keywords.trim();        Store store = (Store) session.getAttribute("loginStore");         if (store != null) {            PageInfo books = bookInfoService.findBookListByCondition(keywords, 0, page, 10, store.getStoreId());            model.addAttribute("bookPageInfo", books);            model.addAttribute("keywords", keywords);        } else {            model.addAttribute("exception", "您请求的资源不存在");            return "exception";        }         return "admin/book/list";    }     /**     * 更新页面回显     *     * @param bookId     * @param model     * @return     * @throws Exception     */    @RequestMapping("/echo")    @RequiresPermissions("book-edit")    public String echo(int bookId, Model model) throws BSException {         BookInfo bookInfo = bookInfoService.adminFindById(bookId);         BookDesc bookDesc = bookDescMapper.selectByPrimaryKey(bookInfo.getBookId());         model.addAttribute("bookInfo", bookInfo);         model.addAttribute("bookDesc", bookDesc);         return "admin/book/edit";    }     @RequestMapping("/update")    @RequiresPermissions("book-edit")    public String updateBook(BookInfo bookInfo, String bookDesc, String keywords, MultipartFile pictureFile, HttpServletRequest request, RedirectAttributes ra) throws Exception {        uploadPicture(bookInfo, pictureFile, request);        BookInfo originBook = bookInfoService.findById(bookInfo.getBookId());        bookInfoService.updateBook(bookInfo, bookDesc);         //更新图片后，删除原来的图片        String realPath = request.getServletContext().getRealPath("/");        File uploadPic = new File(realPath + originBook.getImageUrl());        uploadPic.delete();        //重定向到书籍列表        ra.addAttribute("keywords", keywords);        return "redirect:/admin/book/list";    }     @RequestMapping("/deletion/{bookId}")    @RequiresPermissions("book-delete")    public String deletion(@PathVariable("bookId") int bookId, String keywords, RedirectAttributes ra, HttpServletRequest request) throws BSException {        BookInfo bookInfo = bookInfoService.findById(bookId);        String realPath = request.getServletContext().getRealPath("/");        File uploadPic = new File(realPath + bookInfo.getImageUrl());        uploadPic.delete();        bookInfoService.deleteBook(bookId);        ra.addAttribute("keywords", keywords);        return "redirect:/admin/book/list";    }     @RequestMapping("/shelf")    @RequiresPermissions("book-shelf")    public String bookOffShelf(int bookId, int isShelf, String keywords, RedirectAttributes ra) {         bookInfoService.changeShelfStatus(bookId, isShelf);        ra.addAttribute("keywords", keywords);        return "redirect:/admin/book/list";    }     private void uploadPicture(BookInfo bookInfo, MultipartFile pictureFile, HttpServletRequest request) throws IOException {        if (pictureFile != null) {            if (!StringUtils.isEmpty(pictureFile.getOriginalFilename())) {                String realPath = request.getServletContext().getRealPath("/" + urlPrefix);                //原始文件名称                String pictureFileName = pictureFile.getOriginalFilename();                //新文件名称                String newFileName = IDUtils.genShortUUID() + pictureFileName.substring(pictureFileName.lastIndexOf("."));                 //上传图片                File uploadPic = new File(realPath + File.separator + newFileName);                 //向磁盘写文件                pictureFile.transferTo(uploadPic);                bookInfo.setImageUrl(urlPrefix + File.separator + newFileName);            }        }    } }

书信息控制层：

@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 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 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);         return "book_list";    } }

用户管理控制层：
