How to implement HTTP Post chunked upload of a big file using java httpclient?

I have an enormous file to upload and serv开发者_运维问答er on other side does support chunked upload. Is there any example of how exactly to do that? Or there is some other library which do that?

Using HttpClient 4 (From Apache)

HttpPost post = new HttpPost(url);
MultipartEntity content = new MultipartEntity(HttpMultipartMode.STRICT);

//To add parameters, use StringBody
content.addPart("param", new StringBody("value"));
content.addPart("param1", new StringBody("value1"));
content.addPart("param2", new StringBody("value2"));

//To add files, use InputStreamBody
content.addPart("source", new InputStreamBody(inputStream, mimeType, fileName)); //OR
content.addPart("source", new InputStreamBody(inputStream, mimeType));

//Finally
post.setEntity(content);

Hope this helps.

Using HttpURLConnection, just set chunked transfer mode.
