我正在尝试使用jxl将数据从Excel工作表导入mysql数据库。我需要从本地机器中选择一个文件并读取其内容并存储在数据库中。我已经创建了一个html页面来选择.XLS类型的文件并向jsp页面发送请求。在jsp页面中，我正在进行所有的读取和复制操作。下面给出的是jsp页面代码：
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@page import="java.io.*,java.sql.*,java.util.*,jxl.*, jxl.read.biff.BiffException"%>
<%@page import="javax.servlet.*" %>
<%@page import="javax.servlet.http.*" %>

Please suggest me where I am wrong.?
答案 0 :(得分：0)
如果您使用的是Windows，则使用ODBC数据源。在那里，您可以定义DSN并将其映射到Excel工作表。
现在，您只需读取数据并写入您的mysql数据库。
注意：为了方便起见
例如，您的Excel工作表看起来像这样。
A B C. X Y Z. P Q R
所以，虽然你可以做的原则
SOP（插入（....）值（'A'，'B'，'C'））
并将此文件另存为* .sql并立即在我的sql db中运行。
