不知道是什么原因？應該怎樣來解決呢？
解決這個錯誤，需要在form表單里面加上加enctype=”multipart/form-data” 這個屬性，不過表單請求傳到另一個jsp或servlet里時，是不能用request.getParameter()來獲取到各個表單元素的值的，如下：
復制代碼 代碼如下:
<%@ page language="Java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ page session="false"%>
<%@ include file="/common/taglibs.jsp"%>
<%@ include file="/common/meta.jsp"%>
<%@ include file="/common/js.jsp"%>
<%@ page import="Java.util.*"%>
<%@ page import="Java.text.SimpleDateFormat"%>
<%@ page import="sdcncsi.ict.util.SysPara"%>
<%@page import="Java.io.*,Java.util.*,sdcncsi.ict.base.attachment.*"%>
<%@ page import="sdcncsi.ict.util.RequestUtil"%>
<%@page import="com.oreilly.servlet.MultipartRequest"%>
<%
String res="true";
request.setCharacterEncoding("UTF-8");
response.setContentType("text/html; charset=UTF-8");
String file=(String)request.getParameter("t_file_excel");
//System.out.println(file);
String accountid3=(String)request.getParameter("accountid3");
String saveDirectory = "";
//獲取配置參數,文件類型,文件大小
/*String date = "";
SimpleDateFormat gs = new SimpleDateFormat("yyyyMMdd");
Date now = new Date();
date = gs.format(now);*/
FileFuns fileFuns = new FileFuns();
try {
//判斷文件類型
String file_type=SysPara.getValue("dxt_sms_multi_sender_file_type");
if(!file.substring(file.lastIndexOf(".")+1).equals(file_type))
{
out.println("<script>");
out.println("alert('錯誤：文件類型錯誤！');");
out.println("</script>");
return;
}
//判斷文件夾是否存在，不存在創建
String file_path = SysPara.getValue("dxt_sms_multi_sender_file_path");
file_path=file_path.replace("http://","http://");
if (!fileFuns.getFileIsExists(file_path)) {
fileFuns.Createdir(file_path);
}
String file_size = SysPara.getValue("dxt_sms_multi_sender_file_size");
//文件上傳后，保存在saveDirectory
saveDirectory = file_path;
RandomFileRenamePolicy rfrp = new RandomFileRenamePolicy();
MultipartRequest multi = null;
System.out.println("saveDirectory"+saveDirectory);
System.out.println("file_size"+file_size);
multi = new MultipartRequest(request, saveDirectory, Integer
.parseInt(file_size), "utf-8", rfrp);
System.out.println("222"+multi);
//輸出反饋信息
Enumeration files = multi.getFileNames();
while (files.hasMoreElements()) {
String name = (String) files.nextElement();
File f = multi.getFile(name);
if (f != null) {
String fileName = multi.getFilesystemName(name);
saveDirectory+=fileName;
}
}
} catch (Exception eu) {
res="false";
eu.printStackTrace();
out.println("<script>");
out.println("alert('錯誤：文件大小超出限制！');");
out.println("</script>");
