统计“总计”和 导出excel表格

1 统计“总计”(不随分页的变化而改变)

步骤：① 写总计的sql；② 取值放入list中；③ 从list中取值放入map中；④ 再放入文本框中 然后显示在列表中

以"客户资金余额client_account_list.jsp"为例：

        List list1 = null;
  Map map1;
  String sqlstr1="";
  String total_balance="";
  String weight="";
  String amount_in="";
  String amount_out="";

  sqlstr1="select sum(nvl(total_balance,0)) as total_balance,sum(nvl(weight,0)) as weight,sum(nvl(amount_in,0)) as         amount_in,sum(nvl(amount_out,0)) as amount_out from (" + sqlstr + ")";
