您好我正在尝试使用weed-fs java 客户端将文件上传到 weed-fs 。我想我已经按照如何安装 weed 的说明成功安装了 weed。总之我
- 用命令启动master
$./weed master - 然后
$./weed volume -port=9444我的应用服务器的卷服务器已经占用了 8080 端口 - 通过使用命令 `$./weed upload -dir="any_dir_with_small_files" 上传文件夹来测试一切是否正常
至此，一切都很好。在我的应用程序中，我尝试multipart/form-data从浏览器发布，该浏览器被调用一个类来处理上传的 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());
}
}
}
}
}
当我运行它时，我会得到很多调试信息

就像 x10 一样，我的屏幕高度会这样继续，不要忘记我设置了一个非常小的字体大小。有人可以告诉我这应该怎么做。如果您能指导我正确地指导杂草 fs 的 java 客户端，我也将不胜感激。提前致谢。
