网上的很多方法都已经过时了
<%@page contentType="text/html" pageEncoding="UTF-8"%><html><head></head><body> <form action="upload.jsp" method="post" enctype="multipart/form-data" name="frm1" id="frm1"><input type="file" name="file1" id="file1"><input type="text" name="t2" id="t2" value="1234"><input type="submit"> </form></body></html>
