前后端交互json字符串

 

//将需要的参数转成json字符串，然后用utf-8编码
var obj = encodeURIComponent(JSON.stringify(this.categories),"utf-8")

//后台将前台的json字符串按照utf-8的格式解码，然后进行转换
@RequestMapping(value = "/updateMaterialDemoInfo.do", method = RequestMethod.POST)@ResponseBodypublic Map<String, Object> updateMaterialDemoInfo(String obj){List<MaterialDemoInfoDTO> list = new ArrayList<MaterialDemoInfoDTO>();try {String param = URLDecoder.decode(obj,"utf-8");list = (List<MaterialDemoInfoDTO>)JSonUtil.json2Obj(param, MaterialDemoInfoDTO.class);} catch (Exception e) {// TODO Auto-generated catch block
            e.printStackTrace();}return materialDemoService.updateMaterialDemoInfo(list);}
