Java 實戰項目錘煉之網上花店商城的實現流程
一、項目簡述
功能: 一套完整的網上花店商場系統,系統支持前臺會員的註冊 登陸系統留言,花朵的品種選擇,詳情瀏覽,加入購物 車,購買花朵等;後臺支持管理員的花朵種類添加,花朵 詳情的添加修改,用戶管理,留言管理,商場新聞管理等。
二、項目運行
環境配置: Jdk1.8 + Tomcat8.5 + mysql + Eclispe (IntelliJ IDEA,Eclispe,MyEclispe,Sts 都支持)
項目技術: JSP + Servlert + html+ css + JavaScript + JQuery + Ajax + Fileupload等等。
商城商品查詢和展示代碼:
商城商品查詢: @Controller public class GoodsController { @Resource private NewBeeMallGoodsService newBeeMallGoodsService; @Resource private NewBeeMallCategoryService newBeeMallCategoryService; @GetMapping({"/search", "/search.html"}) public String searchPage(@RequestParam Map<String, Object> params, HttpServletRequest request) { if (StringUtils.isEmpty(params.get("page"))) { params.put("page", 1); } params.put("limit", Constants.GOODS_SEARCH_PAGE_LIMIT); //封裝分類數據 if (params.containsKey("goodsCategoryId") && !StringUtils.isEmpty(params.get("goodsCategoryId") + "")) { Long categoryId = Long.valueOf(params.get("goodsCategoryId") + ""); SearchPageCategoryVO searchPageCategoryVO = newBeeMallCategoryService.getCategoriesForSearch(categoryId); if (searchPageCategoryVO != null) { request.setAttribute("goodsCategoryId", categoryId); request.setAttribute("searchPageCategoryVO", searchPageCategoryVO); } } //封裝參數供前端回顯 if (params.containsKey("orderBy") && !StringUtils.isEmpty(params.get("orderBy") + "")) { request.setAttribute("orderBy", params.get("orderBy") + ""); } String keyword = ""; //對keyword做過濾 去掉空格 if (params.containsKey("keyword") && !StringUtils.isEmpty((params.get("keyword") + "").trim())) { keyword = params.get("keyword") + ""; } request.setAttribute("keyword", keyword); params.put("keyword", keyword); //封裝商品數據 PageQueryUtil pageUtil = new PageQueryUtil(params); request.setAttribute("pageResult", newBeeMallGoodsService.searchNewBeeMallGoods(pageUtil)); return "mall/search"; } @GetMapping("/goods/detail/{goodsId}") public String detailPage(@PathVariable("goodsId") Long goodsId, HttpServletRequest request) { if (goodsId < 1) { return "error/error_5xx"; } NewBeeMallGoods goods = newBeeMallGoodsService.getNewBeeMallGoodsById(goodsId); if (goods == null) { return "error/error_404"; } NewBeeMallGoodsDetailVO goodsDetailVO = new NewBeeMallGoodsDetailVO(); BeanUtil.copyProperties(goods, goodsDetailVO); goodsDetailVO.setGoodsCarouselList(goods.getGoodsCarousel().split(",")); request.setAttribute("goodsDetail", goodsDetailVO); return "mall/detail"; } }
驗證碼生成代碼:
驗證碼生成: @Component public class KaptchaConfig { @Bean public DefaultKaptcha getDefaultKaptcha(){ com.google.code.kaptcha.impl.DefaultKaptcha defaultKaptcha = new com.google.code.kaptcha.impl.DefaultKaptcha(); Properties properties = new Properties(); properties.put("kaptcha.border", "no"); properties.put("kaptcha.textproducer.font.color", "black"); properties.put("kaptcha.image.width", "150"); properties.put("kaptcha.image.height", "40"); properties.put("kaptcha.textproducer.font.size", "30"); properties.put("kaptcha.session.key", "verifyCode"); properties.put("kaptcha.textproducer.char.space", "5"); Config config = new Config(properties); defaultKaptcha.setConfig(config); return defaultKaptcha; } }
