今天完成的事情:

增加前台用户列表接口,增加排名接口

@RequestMapping(value = "/a/u/user/rank", method = RequestMethod.GET)
   public String getuserListJson( ModelMap model,HttpServletRequest request) throws Exception {
//    验参

      ArrayList arrayList=new ArrayList <>();
      List listRank=new ArrayList();
      List<User> users=new ArrayList <>();
      int i=1;
      try {
         log.info("=====获取用户ID=====");
         String token = CookieUtil.getCookie(request, "token");
         String[] mToken = DesUtil.getStrM(token).split(",");
         Long uid = Long.parseLong(mToken[0]);
//          冻结用户不参与排名
            Map <String, Object> params = DynamicSQL.getUnfrozenUserList();
            List <Long> ids = userService.getIdsByDynamicCondition(User.class, params, 0, Integer.MAX_VALUE);
            users = userService.getObjectsByIds(ids);
//          对用户集合进行排序
//          排序规则:已学课时数相同时,学习天数更多的排前面；完全一样按注册先后排序
            Collections.sort(users, new Comparator <User>() {
               public int compare(User o1, User o2) {
                  int x = (o2.getLearnPeriod() - o1.getLearnPeriod());
                  int y = (o2.getLearnTime() - o1.getLearnTime());
                  int z = (int) (o1.getCreateAt() - o2.getCreateAt());
                  if (x == 0) {
                     if (y == 0) {
                        return z;
                     }
                     return y;
                  }
                  return x;
               }
            }
            );
            for (User userRank : users
                  ) {
               Map map = new HashMap();
               map.put("id", userRank.getId());
               map.put("name", userRank.getName());
               map.put("learnPeriod", userRank.getLearnPeriod());
               map.put("learnTime",userRank.getLearnTime());
               arrayList.add(map);
            }
            log.info("=====查询排名后用户位置=====");
            for (User userRank:users
                ) {
               if (userRank.getId().equals(uid)){
                  model.addAttribute("myScore",userRank.getScore());
                  model.addAttribute("myLearnTime",userRank.getLearnTime());
                  model.addAttribute("myLearnPeriod",userRank.getLearnPeriod());
                  model.addAttribute("beat",(new DecimalFormat("0.0%")).format(((double) (users.size()-i))/((double)(users.size()))));
                  break;
               }
               i++;
            }
//          取排名后集合前5条
            listRank = arrayList.subList(0,5);
            model.addAttribute("list", listRank);
            model.addAttribute("code", 0);

      }catch (Exception e){
         model.addAttribute("code",-1);
         log.info("系统错误");
         e.printStackTrace();
      }
      return "/jsps/user-jsp/json/userListJson";
   }
