JSP頁面代碼：
<body>
<form action="${pageContext.request.contextPath}/FileUplod" ? ? ??method="post" enctype="multipart/form-data">
<防和諧input type="file" name ="file2"/>
<防和諧input type="file" name ="file2"/>
<防和諧input type="submit" value="提交"/>
</body>
<防和諧/form>
Servlet頁面內(nèi)Java代碼：
String uploadFilePath=request.getSession().getServletContext().getRealPath("/uplod"); //獲取JSP頁面的form表單是不是為 //enctype="multipart/form-data"
boolean isMultipart =ServletFileUpload.isMultipartContent(request);try {
if(isMultipart){
//創(chuàng)建工廠
FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload= new ServletFileUpload(factory);
Listitems = upload.parseRequest(request);? ?
?Iteratoriter = items.iterator();
while(iter.hasNext()){?
//依次處理每個(gè)文件
FileItem item = iter.next();
String fileName= item.getName(); //表單字段的name屬性值
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
