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:'${root}/notice/multiNoticeList.do?params='+params,
onclose:function(){
//location.reload();
}
}).showModal();
后台获取json数据，并转成list，然后在ie模式，获取到的json数据都出现中文乱码，然后导致json不能解析报错了
String params = request.getParameter("params");
logger.info("文书参数转换前:》》"+params);
params=StringEscapeUtils.unescapeJava(params);
logger.info("文书参数转换后:》》"+params);
ObjectMapper mapper = new ObjectMapper();
JavaType javaType = mapper.getTypeFactory().constructParametricType(List.class, ApprWritUnionFormModel.class);
/*List<FormModel> writUnionFormList =
JSON.parseArray(params, FormModel.class);*/
List<FormModel> writUnionFormList=new ArrayList<FormModel>();
try {
writUnionFormList = (List<FormModel>)mapper.readValue(params, javaType);
} catch (JsonParseException e) {
e.printStackTrace();
} catch (JsonMappingException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
针对上面问题，和同事讨论，最开始打算base64加密来传，然后发现base64加密中文出现问题，所以改成URLEncode的方式，前端加密两遍，后台在解密一遍
var params = JSON.stringify(writParamList);
top.dialog({
id: 'noticeList',
title:'列表',
width:900,
height:500,
url:'${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();
}
