java实现将Excel表导入数据库

一.java实现将Excel表导入数据库需要三个页面(以导入国税评定数据为例)：

（1）drgspdsj.jsp页面（表单页面）：

<%@ page language="java" import="java.util.*" pageEncoding="GBK"%>

<%@page import="com.hhzs.nsxydj.common.Tools"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

String nsrsbh = Tools.nullToSpace(request.getParameter("nsrsbh"));

<title>导入国税评定数据</title>

<style type="text/css">

}

table .header:hover {

text-decoration: none

table tr {

}

table tr:hover {

}

</style>

<script type="text/javascript">

return;

}

var arr = document.getElementsByName("scfj");

if(arr[i].value != "" && !uploadFileCheck(arr[i])){

return false;

}

}

var formxx = document.getElementByIdx_x_x_x("formxx");

showOrHideDiv("divCtais","block");

formxx.action = "gsbc.jsp";

formxx.submit();

}





//验证文件格式

function uploadFileCheck(objF){//验证文件

var regImg = new RegExp(/\.(xls|XLS|XLs|Xls)$/);

var FileMaxSize = 2048;

var obj=objF.value;

var fileObj = objF;

if(!obj.match(regImg)){

fileObj.outerHTML=fileObj.outerHTML.replace(/(value=").+"/i,"$1"");
