我们公司目前做的项目采用nutz框架，我现在需要做一个多文件上传功能，前端用的swfupload插件，后台用的是fileupload，其他项目使用这两个插件没有任何问题。在nutz框架里面使用时，一直报一个错误，Stream closed，想问问是怎么回事？对nutz框架还不是太熟悉。求大神指教@wendal。
/**
* 文件上传

@POST
@AdaptBy(type = UploadAdaptor.class,args = {"ioc:upload"})
@At
public void uploadFile(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
//System.out.println("name====>"+request.getParameter("name"));
DiskFileItemFactory factory = new DiskFileItemFactory();
//设置内存缓冲区，超过后写入临时文件
factory.setSizeThreshold(10240000);
//设置临时文件存储位置
String base = "f:/uploadFiles";
File file = new File(base);
if(!file.exists())
file.mkdirs();
factory.setRepository(file);
ServletFileUpload upload = new ServletFileUpload(factory);
// 设置单个文件的最大上传值
upload.setFileSizeMax(10002400000l);
// 设置整个request的最大值
upload.setSizeMax(10002400000l);
upload.setHeaderEncoding("UTF-8");
try {
List<?> items = upload.parseRequest(request);【这里抛出的异常】
FileItem item = null;
String fileName = null;
for (int i = 0 ;i < items.size(); i++){
item = (FileItem) items.get(i);
fileName = base + File.separator + item.getName();
// 保存文件
if (!item.isFormField() && item.getName().length() > 0) {
item.write(new File(fileName));
}
}
} catch (FileUploadException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
