ajax上传map类型数据，后台解析

1.ajax上传map类型数据

var rebate="";
var typeKey="";

var rebateMap = {};
var str ="";
$('.rebateCss').each(function () {
rebate = $(this).val();
typeKey=$(this).attr("typeCate");
rebateMap[typeKey] = rebate;

//主要：map转json字符串放入data

str = JSON.stringify(rebateMap);
});
$.ajax({
url: "merchant_settled!getexamineIsPass.action",
data: {"id": id,"rebate":str},

2.后台解析：

String rebate = request.getParameter("rebate");

JSONObject jb = JSONObject.fromObject(rebate); Map map = (Map)jb; Iterator<String> iter = map.keySet().iterator(); while (iter.hasNext()) { String key = iter.next(); String value = (String) map.get(key); String[] typeCate = key.split("_"); for (int i = 0 ; i <typeCate.length ; i++ ) { Integer param=Integer.parseInt(typeCate[i]); if(i==0){ //类型id ProductTypeInfo type=productTypeService.get(param); }else{ ProductCategoryInfo cate=productCategoryInfoService.get(param); } } }
