前台需要传成组数据且是动态的.拼接成json字符串,ajax传到后台然后解析.

  前台拼接json数组后台接受 
  前台代码 : 
      function makePicNameJson (){
          var picNameListForJson = '{"picNameListForUpload": [';
          $(".picInputsArae").children().each(function(){
              picNameListForJson += '{"realName":"' + $(this).attr("id") +' ","fileName":"' + $(this).attr("class") +'" },';
          });
          picNameListForJson = picNameListForJson.substring(0,picNameListForJson.length-1);
          picNameListForJson += ']}';
          $("#picNameListForJson").attr("value",picNameListForJson);
          //alert($("#picNameListForJson").val());
      }

  
  

后台json读取方式:

JSONObject.fromObject(picNameListArray.get(i)).get("fileName").toString()

  后台接受处理 :
  以string形式接受
  JSONObject picNameListObject  = JSONObject.fromObject(picNameListForJson);
  JSONArray picNameListArray = picNameListObject.getJSONArray("picNameListForUpload");
  for (int i = 0; i < picNameListArray.size(); i++) {
      LwApplicateFinishiAddendum lwApplicateFinishiAddendum = new LwApplicateFinishiAddendum();
      lwApplicateFinishiAddendum.setProjectId(projectId);
      lwApplicateFinishiAddendum.setWorkerId(((UserInfoSS)getUser()).getId());
      lwApplicateFinishiAddendum.setPicName(JSONObject.fromObject(picNameListArray.get(i)).get("realName").toString());
      lwApplicateFinishiAddendum.setPicSysName(JSONObject.fromObject(picNameListArray.get(i)).get("fileName").toString());
      lwApplicateFinishiAddendum.setPid(lwApplicateFinish.getId());
      HibernateDAO.save(lwApplicateFinishiAddendum);                
   }
