1.首先将数据存储到list中
List<HashMap> tjlist = new ArrayList<HashMap>();
//下面这个得到是一个数组，下面会进行处理
com.alibaba.fastjson.JSONArray json= gAction.getLlsMap();2.将得到的数据装入map中
Map<String, Object> beanParams = new HashMap<String, Object>();
beanParams.put("list", tjlist);
beanParams.put("list2", json);3.获取导出文件的路径并将数据导出
String mobanPath = ContextUtil.getRealPath() + "/WEB-INF/zljdpt/template/bbbbbbbbbb.xls";
tableTOexcel(response,beanParams,mobanPath);
public void tableTOexcel(HttpServletResponse response,Map<String, Object> map,String mobanPath){
