导出数据到Excel：
1. 将数据查询出来返回给导出jsp页面。
//导出数据 @RequestMapping(value ="/chongLog_info_xls",produces="text/html;charset=UTF-8") public String consume_info_xls(String q_start_date,String q_end_date,Model map,HttpServletRequest request,String user_type,String q_tel,String status){ String q_str=""; if(q_tel!=null && !q_tel.equals("")){ q_str+=" and a.tel like '%"+q_tel+"%'"; } if(StringUtils.isNotBlank(q_start_date)){ q_str+=" and to_char(a.insert_date,'yyyy-MM-dd') >='"+q_start_date+"'"; } if(StringUtils.isNotBlank(q_end_date)){ q_str+=" and to_char(a.insert_date,'yyyy-MM-dd') <='"+q_end_date+"'"; } String sql="select a.name a__name,a.tel a__tel,c.money c__money,c.insert_date c__insert_date,c.balance c__balance,c.balance+c.money c__after" + " from t_fg_user a,T_CHONG_LOG c where a.id=c.user_id " + " and 1=1 "+q_str+" order by c.insert_date desc"; List list=proxy_jyyzService.findall(sql); map.addAttribute("list", list); return "bg/finance/chongLog_info_xls"; }
2. 导出功能jsp文件配置
chongLog_info_xls.jsp:
