项目中做导入的时候遇到个bug，用JSON.stringify()序列号json对象传给后台；然后后台通过getPatameter()获取值时，前台的英文引号变成了中文引号。

原来代码如下：（自己排查发现就算是英文的时候也是如此）

//提交事件
$("#submitButton").bind("click",function(){
if($("#addForm").valid()){
var jsonStr = {};
$("#itemTable").find("input[lang='userAdd']").each(function(index,obj){
var nameAttr = $(obj).attr("id").trim();
var valueAttr = $('#'+nameAttr).combobox('getValue').trim();
if (valueAttr != "" && valueAttr != undefined) {
jsonStr[valueAttr] = nameAttr;
}
});
var json = new Object();
json.name = "ss";
json.age = "";
var data = JSON.stringify(json);
var att = {};
att["password"] = $("#text_pwd").val();
att["organization"] = $("#text_organization").combotree("getValue"); $(this).attr("disabled","disabled");
Loading(true,"<s:text name='cems.soft.progress.handling'></s:text>");//遮罩提示
$.doAjax({
url:'${basePath}/user/userAction_userAdd.do',
data:{"data":data,"arrdata":JSON.stringify(att)},
async:true,
success:function(responseText){

在后台获取时，前台的英文引号，在后台变成了中文引号，导致JSON解析出错，报异常：net.sf.json.JSONException: Unquotted string '”ss”'

/**
* 映射字段
*/
public void userAdd(){
log.info("用户批量导入_PBEG");
this.msg=RESULT_FAIL;
long startTime = System.currentTimeMillis();//获取当前时间
String initPassword = "";
File file = null;
List<User> list = new ArrayList<User>();
List<UserCache> userCaches = new ArrayList<UserCache>();
List<String> failedFailName = new ArrayList<String>();
Organization default_org = null;
try {
String data = getRequest().getParameter("data");
String arrdata =getRequest().getParameter("arrdata");
JSONObject jsonData = JSONObject.fromObject(data);
JSONObject jsonArrdata = JSONObject.fromObject(arrdata);
String arrPassword = jsonArrdata.containsKey("password") ? jsonArrdata.getString("password") : "";
String arrOrganization = jsonArrdata.containsKey("organization") ? jsonArrdata.getString("organization") : "";

解决方案：

经过几次json转换的尝试，发现结果均是如此，所以最后决定采用注入的方式处理。

//提交事件
$("#submitButton").bind("click",function(){
if($("#addForm").valid()){
var jsonStr = {};
$("#itemTable").find("input[lang='userAdd']").each(function(index,obj){
var nameAttr = $(obj).attr("id").trim();
var valueAttr = $('#'+nameAttr).combobox('getValue').trim();
if (valueAttr != "" && valueAttr != undefined) {
jsonStr[valueAttr] = nameAttr;
}
});
var data = JSON.stringify(jsonStr);
var att = {};
att["password"] = $("#text_pwd").val();
att["organization"] = $("#text_organization").combotree("getValue"); $(this).attr("disabled","disabled");
Loading(true,"<s:text name='cems.soft.progress.handling'></s:text>");//遮罩提示
$.doAjax({
url:'${basePath}/user/userAction_userAdd.do',
data:{"data":data,"arrdata":JSON.stringify(att)},
async:true,
success:function(responseText){

后台：采用注入方式

private String data;
public String getData() {
return data;
}
public void setData(String data) {
this.data = data;
} private String arrdata;
public String getArrdata() {
return arrdata;
}
public void setArrdata(String arrdata) {
this.arrdata = arrdata;
}
/**

List<UserCache> userCaches = new ArrayList<UserCache>();
List<String> failedFailName = new ArrayList<String>();

throw new IllegalStateException("用户批量导入-->用户导入临时文件不存在!");
}
