本文介绍了一个使用Struts2框架实现文件上传的例子。通过ServletFileUpload组件解析HTTP请求中的文件，设置文件大小限制，并将文件保存到指定路径。示例中还包括了JSP页面代码。

//服务器断
private void saveFiletoServer(HttpServletRequest request,HttpServletResponse response,String uploadPath)
{
// 操作文件
response.setContentType("text/html; charset=UTF-8");
DiskFileItemFactory factory = new DiskFileItemFactory();
factory.setSizeThreshold(1024 * 4);
ServletFileUpload upload = new ServletFileUpload(factory);
upload.setFileSizeMax(maxPostSize);
logger("request========" + ObjectUtils.toString(request));
List fileItems = null;
try {
fileItems = upload.parseRequest(request);
logger("============" + ObjectUtils.toString(fileItems));
Iterator iter = fileItems.iterator();
while (iter.hasNext()) {
FileItem item = (FileItem) iter.next();
log(item.toString());
if (!item.isFormField()) {
String name = item.getName();
logger("上传的文件名 = " + name);
try {
item.write(new File(uploadPath + name));
} catch (Exception ex) {
logger(ex.getMessage());
}
}
}
} catch (FileUploadException ex1) {
logger("FileUploadException->" + ex1.getMessage());
}
}
