json-jquery-struct 解析例子(map) - 批量导入解析和批量导出

1、点击批量导入，先做个弹出层
   弹出层里面选择文件和返回信息
   确定导入
   返回信息，追加到div里面展示

$.getJSON(encodeURI('xxxAction!toImportExcel.action?filePat
h='+filePath),function(result){
	$.each(result.ERROR_LIST,function(key,value){
		$("#message").append("<font 
	color='red'>"+key+":"+value.errorInfor+"</font><br/>");
	});
});

ACTION - service 主要调用组件类，封装了map集合,列出错误格式集合或正确导入集合

private JSONObject jsonObject = new JSONObject();
//get-set method JSONObject 
// 获取 excel path路径
String filePath = new String(ServletActionContext.getRequest().getParameter("filePath").getBytes("iso8859-1"),"utf-8");
// 获取 map 集合
Map<String,List<ExcelBean>> map = 
	this.customerService.toImportExcel(filePath );
//遍历 map
Iterator it = map.entrySet().iterator();
	List<ExcelBean> errorList = null;
	List<ExcelBean> successList = null;
	while(it.hasNext()){
		Map.Entry mapEntry = (Map.Entry)it.next();
		if(mapEntry.getKey().equals("fail")){
			errorList = (List<ExcelBean>)mapEntry.getValue();
		}else if(mapEntry.getKey().equals("success")){
			successList = (List<ExcelBean>)mapEntry.getValue();
		}
	}
// 返回错误集合 或 操作 批量插入
if(errorList.size() != 0){
    		System.out.println("有错误excel格式,不执行批量操作,返回错误列表");
    		ServletActionContext.getResponse().setCharacterEncoding("UTF-8");
    		JSONArray jsonArray = JSONArray.fromObject(errorList);
    		jsonObject.put("ERROR_LIST", jsonArray);
    		ServletActionContext.getResponse().getWriter().write(jsonObject.toSt
			ring());
    		System.out.println("json :" + jsonObject.toString());
    		return null;
    	}else{
//    		调用dao层执行批量插入操作
    		System.out.println("调用dao层执行批量插入操作");
//    		封装解析成功的数据格式返回
//    		dosomething ...
    		return null;
    	}

xml配置
