Java實戰網上電子書城的實現流程
項目描述: spring mvc +jsp實現的簡單書城項目,可以在支付寶沙箱內實現支付
運行環境: jdk8+tomcat9+mysql+IntelliJ IDEA
項目技術: spring+spring mvc+mybatis+jsp+maven
後臺管理員圖書管理代碼:
@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"; } /** * 添加書籍 * */ @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"; } /** * 書籍列表 * */ @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<BookInfo> books = bookInfoService.findBookListByCondition(keywords, 0, page, 10, store.getStoreId()); model.addAttribute("bookPageInfo", books); model.addAttribute("keywords", keywords); } else { model.addAttribute("exception", "您請求的資源不存在"); return "exception"; } return "admin/book/list"; } /** * 更新頁面回顯 * * @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); //更新圖片後,刪除原來的圖片 String realPath = request.getServletContext().getRealPath("/"); File uploadPic = new File(realPath + originBook.getImageUrl()); uploadPic.delete(); //重定向到書籍列表 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); //原始文件名稱 String pictureFileName = pictureFile.getOriginalFilename(); //新文件名稱 String newFileName = IDUtils.genShortUUID() + pictureFileName.substring(pictureFileName.lastIndexOf(".")); //上傳圖片 File uploadPic = new File(realPath + File.separator + newFileName); //向磁盤寫文件 pictureFile.transferTo(uploadPic); bookInfo.setImageUrl(urlPrefix + File.separator + newFileName); } } } }
書信息控制層:
@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); //查詢書籍推薦列表 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列表 * * @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"; } }
用戶管理控制層:
