我想在JSP中读取一个excel文件,为此我首先使用Web应用程序项目将文件上传到名为uploads的:D分区的文件夹中,我尝试用另一个java projet 读取excel上传文件.这两个代码都在工作.这是通过Web应用程序项目(JSP和SERVLET)在特定文件夹中上传的代码:
图书馆
的index.jsp
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<title>Upload File</title>
</head>
<body>
<form action="UploadFile" method="post" enctype="multipart/form-data">

<input type="submit" value="Upload File">
