首先需要两个jar包的支持commons-fileupload-1.3.jar commons-io-2.4.jar放入WEB_INF的lib包下
上传的界面代码：
upload.html
enctype="multipart/form-data">
Text1:
File2:
html>
上传的处理jsp代码：
<%@ page language="java" contentType="text/html; charset=GBK"
pageEncoding="GB18030"%>
<%@ page import="org.apache.commons.fileupload.*"%>
<%@ page import="org.apache.commons.fileupload.servlet.*"%>
<%@ page import="org.apache.commons.fileupload.disk.*"%>
<%@ page import="java.util.*"%>
<%@ page import="java.io.*"%>
<%
String uploadPath="f:\\fileupload";
boolean isMultipart = ServletFileUpload.isMultipartContent(request);
if(isMultipart==true){
try{
FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
List items = upload.parseRequest(request);//得到所有的文件
Iterator itr = items.iterator();
while(itr.hasNext()){//依次处理每个文件
FileItem item=(FileItem)itr.next();
String fileName=item.getName();//获得文件名，包括路径
if(item.isFormField()){
System.out.println("name ============== " + item.getFieldName()+new String(item.getString().getBytes("iso8859-1"),"GBK"));
}
else if(fileName!=null){
File savedFile=new File(uploadPath,item.getName());
item.write(savedFile);
}
}
out.print("upload succeed");
}
catch(Exception e){
e.printStackTrace();
}
}
else{
out.println("the enctype must be multipart/form-data");
}
%>
upload2.html
