Http请求传json数据中文乱码问题

业务场景:调easyui的dialog打开一个弹窗,传参是用json封装的,而且有中文,然后在极速模式是正常的,在ie11测试发现中文出现乱码了

var params = JSON.stringify(writParamList);
    top.dialog({
                 id: 'noticeList',
                 title:'列表',
                 width:900,
                height:500,
                url:'${root}/notice/multiNoticeList.do?params='+params,
                onclose:function(){
                            //location.reload();
                 }
    }).showModal();

后台获取json数据,并转成list,然后在ie模式,获取到的json数据都出现中文乱码,然后导致json不能解析报错了

String params = request.getParameter("params");
            logger.info("文书参数转换前:》》"+params);
            params=StringEscapeUtils.unescapeJava(params);
            logger.info("文书参数转换后:》》"+params);
            ObjectMapper mapper = new ObjectMapper();
            JavaType javaType = mapper.getTypeFactory().constructParametricType(List.class, FormModel.class);
            /*List<FormModel> writUnionFormList = 
                    JSON.parseArray(params, FormModel.class);*/
            List<FormModel> writUnionFormList=new ArrayList<FormModel>();
            try {
                writUnionFormList = (List<FormModel>)mapper.readValue(params, javaType);
            } catch (JsonParseException e) {
                e.printStackTrace();
            } catch (JsonMappingException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }

针对上面问题,和同事讨论,最开始打算base64加密来传,然后发现base64加密中文出现问题,所以改成URLEncode的方式,前端加密两遍,后台在解密一遍

var params = JSON.stringify(writParamList);
    top.dialog({
                 id: 'noticeList',
                 title:'列表',
                 width:900,
                height:500,
                url:'${root}/notice/multiNoticeList.do?params='+encodeURI(encodeURI(params)),
                onclose:function(){
                            //location.reload();
                 }
    }).showModal();

后台代码修改,解码一遍,然后发现在ie也正常

String params = request.getParameter("params");
            logger.info("文书参数转换前:》》"+params);
            //params=StringEscapeUtils.unescapeJava(params);
    //      byte[] buffer=Base64Utils.decodeFromString(params);
    //      params = new String(buffer);
             try {
                 params=URLDecoder.decode(params,"utf-8");
            } catch (UnsupportedEncodingException e1) {
                e1.printStackTrace();
            }
            logger.info("文书参数转换后:》》"+params);
            ObjectMapper mapper = new ObjectMapper();
            JavaType javaType = mapper.getTypeFactory().constructParametricType(List.class, ApprWritUnionFormModel.class);
            /*List<FormModel> writUnionFormList = 
                    JSON.parseArray(params, FormModel.class);*/
            List<FormModel> writUnionFormList=new ArrayList<FormModel>();
            try {
                writUnionFormList = (List<FormModel>)mapper.readValue(params, javaType);
            } catch (JsonParseException e) {
                e.printStackTrace();
            } catch (JsonMappingException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
