使用org.apache.poi导出Excel表格

@RequestMapping(value="/exportExcel")
public void exportExcel(HttpServletResponse response){
   List list = new ArrayList();//根据title的顺序吧字段放进去
   String fileName ="站点信息"+".xls";//excel文件名
   String sheetName = "站点信息表";//sheet名
   //excel标题
   String[] title = {"站点名称","站点编号","所属企业","所属地市","所属省份","站点类型","站点位置","线路数量","创建日期","是否启用","负责人","联系电话"};
   //创建HSSFWorkbook
   HSSFWorkbook wb = ExcelUtil.getHSSFWorkbook(sheetName, title, list, null);
   //响应到客户端
   try {
      ExcelUtil.setResponseHeader(response, fileName);
      OutputStream os = response.getOutputStream();
      wb.write(os);
      os.flush();
      os.close();
   } catch (IOException e) {
      e.printStackTrace();
   }
}
