Question

您好我正在尝试使用weed-fs java client将文件上传到weed-fs。我想我已按照说明of how to install weed成功安装了杂草。总之我

使用命令$./weed master
然后我的应用服务器$./weed volume -port=9444的卷服务器已经占用了端口8080
使用命令`$。/ weed upload -dir =＆＃34; any_dir_with_small_files＆＃34;

到目前为止一切都很顺利。在我的应用程序中，我尝试从浏览器发布multipart/form-data，该浏览器由调用类来处理上传的servlet拦截。

    public void upload(HttpServletRequest request) throws FileUploadException, IOException {
    client = new WeedFSClient(MASTER_ADDRESS, MASTER_PORT);
    if (ServletFileUpload.isMultipartContent(request)) {
        FileItemIterator fileItemIterator = new ServletFileUpload().getItemIterator(request);
        InputStream inputStream = null;
        while (fileItemIterator.hasNext()) {
            FileItemStream item = fileItemIterator.next();
            if (!item.isFormField()) {
                inputStream = item.openStream();
                File file = new File(request.getServletContext().getRealPath("/")+"img/uploads/"+item.getName());
                FileOutputStream fos = new FileOutputStream(file);
                Streams.copy(inputStream, fos, true);
                RequestResult result = client.upload(file);
                if (result.isSuccess()) {
                    System.out.println("uploaded file with ID "+result.getFid());
                }
            }
        }
    }
}

当我运行这个时，我得到了很多调试信息

这就像这样继续像x10我屏幕的高度不要忘记我设置了一个非常小的字体大小。有人可以告诉我应该怎么做。如果你可以指导我为杂草fs提供java客户端的正确指南，我也将不胜感激。提前谢谢。
