示范：
JSP页面代码：
<body>
<form action="${pageContext.request.contextPath}/FileUplod" method="post" enctype="multipart/form-data">
<防和谐input type="file" name ="file2"/>
<防和谐input type="file" name ="file2"/>
<防和谐input type="submit" value="提交"/>
</body>
<防和谐/form>
Servlet页面内Java代码：
String uploadFilePath=request.getSession().getServletContext().getRealPath("/uplod"); //获取JSP页面的form表单是不是为 //enctype="multipart/form-data"
boolean isMultipart =ServletFileUpload.isMultipartContent(request);try {
if(isMultipart){
//创建工厂
FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload= new ServletFileUpload(factory);
Listitems = upload.parseRequest(request);
Iteratoriter = items.iterator();
while(iter.hasNext()){
//依次处理每个文件
FileItem item = iter.next();
String fileName= item.getName(); //表单字段的name属性值
if(fileName !=null && fileName!=""){
File src= new File(item.getName());
File save = new File(uploadFilePath, item.getName());
item.write(save);
}
}
}
} catch (FileUploadException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
