经验分享之前台Map数据的显示

前台Map数据的显示：

controller:

//-----------根据稿件Id查询稿件信息-----------start------------
  @ResponseBody
  @RequiresPermissions("sys:uploadPictorial:edit")
  @RequestMapping(value = "queryManuscriptById")
  public Map<String,Object> queryManuscriptById(@RequestParam Map<String,String> params,HttpServletRequest request,HttpServletResponse response,ManuscriptInfo manuscriptInfo, Model model) {

    String pictorialId = request.getParameter("pictorialId");//获取期刊的ID
    Map<String,Object> paramMap=new HashMap<String,Object>();
    PictorialInfo pictorialInfo = new  PictorialInfo();
    //从Mongo数据库中读取稿件信息
    paramMap.put("id", manuscriptId);
    ManuscriptInfo m=mongoService.findObject(ManuscriptInfo.class,paramMap,null,null,null,null,null,null);
    //获取期刊的总页数
    if(!StringUtils.isEmpty(pictorialId)){
      pictorialInfo = uploadpictorialService.get(pictorialId);
    }
    int totalPage = pictorialInfo.getPgNum();
    
    //计算起始页和结束页，并将计算出来的数据放入retMap
    Map<String,Object> retMap=new HashMap<String,Object>();
    int startPage = m.getPgStart();
