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, ApprWritUnionFormModel.class);

/*List writUnionFormList =

JSON.parseArray(params, FormModel.class);*/

List writUnionFormList=new ArrayList();

try {

writUnionFormList = (List)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 writUnionFormList =

JSON.parseArray(params, FormModel.class);*/

List writUnionFormList=new ArrayList();

try {

writUnionFormList = (List)mapper.readValue(params, javaType);

} catch (JsonParseException e) {

e.printStackTrace();

} catch (JsonMappingException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}
