Java后台Excel表导出

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
