项目目录结构

【JS】ssm搭建拍卖系统

  • controller，视图控制层，

  • service，业务逻辑层

  • dao，数据库操作层

  • jsp，页面进行数据渲染

  • mapper.xml,此文件定义了操作数据库的sql，每个sql是一个statement，映射文件是mybatis的核心

  • jdbc.properties，数据库帐号密码配置

运行效果

  • 注册

核心项目配置:

1.spring-mvc.xml配置：

</beans>

2.spring-mybatis.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">

3.登录验证

@RequestMapping("/checkLogin")
@ResponseBody
public int checkLogin(HttpServletRequest request, String uname, String upassword, String verifyCode) {
HttpSession session = request.getSession(); String sessionVerifyCode = (String) session.getAttribute("verifyCodeValue"); if (!verifyCode.equalsIgnoreCase(sessionVerifyCode)) { int flag = 4; return flag;
} else { List<PUsersModel> pUsersModels = pUserService.checkLogin(uname, upassword); if (pUsersModels.isEmpty()) { return 0;//用户名不存在
} String relpassword = pUsersModels.get(0).getUpassword(); int utype = pUsersModels.get(0).getUtype(); if (upassword.equals(relpassword)) { session = request.getSession(); session.setAttribute("uname", uname); session.setAttribute("utype", utype); session.setAttribute("pUsersModel", pUsersModels.get(0)); if (utype == 1) { return 3;//管理员
} return 1;//密码正确
} else { return 2;//密码不正确
} }}

4.系统推荐

@RequestMapping("/sysRecommend")
public String sysRecommend(HttpSession session, Model model, String page)
{
PUsersModel pUsersModel=(PUsersModel)session.getAttribute("pUsersModel"); //先判断当前用户是否已经浏览过商品
LookshistoryModel lookModel=new LookshistoryModel(); lookModel.setUserid(pUsersModel.getUid()); List<LookshistoryModel> lists=lookshistoryService.selectLookshistory(lookModel);      //查询总记录并做降序处理
Map<Integer,Integer> gmap=new HashMap<Integer, Integer>(); if(lists!=null&lists.size()>0){                                           //根据做商品过滤筛选 精准推荐
int hits=0;                                                          //获取浏览总数
for(LookshistoryModel m:lists){ gmap.put(m.getPgtype(),m.getHits());                                 //填充商品占比情况
hits+=m.getHits();                                              //叠加浏览次数
} Map<Integer,Integer> gpmap=new HashMap<Integer, Integer>();                               //对象储存转换，类型--->>次数 模式
for (Map.Entry<Integer, Integer> entry : gmap.entrySet()) { BigDecimal percentage=new BigDecimal(entry.getValue()).divide(new BigDecimal(hits),2,BigDecimal.ROUND_HALF_DOWN);     //当前最高商品的占比
int result=percentage.multiply(new BigDecimal(12)).intValue();                   //推荐每个商品出现的占比情况
gpmap.put(entry.getKey(),result); } List<GoodsModel> afterGoodsModels =new ArrayList<GoodsModel>(); int afterPageNums =0; for (Map.Entry<Integer, Integer> entry : gmap.entrySet()) {                         //最终推荐出商品情况
int afterPageItem = goodsService.countAfterGoodsByKinds(entry.getKey()); final int afterPageSize = entry.getValue(); if (page == null) { page = "1"; } PageUtil afterPageUtil = new PageUtil(afterPageItem, afterPageSize, Integer.parseInt(page)); int afterPageNum = afterPageUtil.getPageNum(); afterPageNums+=afterPageNum; int afterStartRow = afterPageUtil.getStartRow(); List<GoodsModel> goodsModels = goodsService.getAfterCheckGoodsByPageBykinds(afterStartRow, afterPageSize, entry.getKey()); Boolean afterHasNextPage = (Integer.parseInt(page) != afterPageNum) && (afterPageNum != 0); model.addAttribute("afterHasPrePage", Integer.parseInt(page) != 1); model.addAttribute("afterHasNextPage", afterHasNextPage); model.addAttribute("afterGoodsModels", afterGoodsModels); model.addAttribute("afterPageItem", afterPageItem);

model.addAttribute("afterGoodsModels", afterGoodsModels);//总商品
}else{                                                             //根据大众浏览推荐
lists=lookshistoryService.selectLookshistory(new LookshistoryModel());          //根据大众浏览次数多的多推荐
if(lists!=null&lists.size()>0){ int hits=0;                                                          //获取浏览总数
for(LookshistoryModel m:lists){ gmap.put(m.getPgtype(),m.getHits());                                 //填充商品占比情况

} Map<Integer,Integer> gpmap=new HashMap<Integer, Integer>();//商品占比存储对象
for (Map.Entry<Integer, Integer> entry : gmap.entrySet()) { BigDecimal percentage=new BigDecimal(entry.getValue()).divide(new BigDecimal(hits));      //当前最高商品的占比
int result=percentage.multiply(new BigDecimal(12)).intValue();                   //推荐每个商品出现的占比情况
gpmap.put(entry.getKey(),result); } List<GoodsModel> afterGoodsModels =new ArrayList<GoodsModel>(); int afterPageNums =0; for (Map.Entry<Integer, Integer> entry : gmap.entrySet()) {             //最终推荐出商品情况

}else{ int lindid=(int)Math.random()*(1);                         //没有浏览次数系统随机推荐
