Upload file stop with Unexpected EOF read on the socket Exception

Not sure about the getBytes() method on the upfile. A more suitable approach would be to use the InputStream which will manage any size file and will buffer when necessary. Something like:

public void save_file(MultipartFile upfile , String path){

    try {
        File fichier = new File( path ) ;
        BufferedOutputStream stream = new BufferedOutputStream(new FileOutputStream( fichier ));
        InputStream is = upfile.getInputStream();
        byte [] bytes = new byte[1024];
        int sizeRead;
        while ((sizeRead = is.read(bytes,0, 1024)) > 0) {
            stream.write(bytes, 0, sizeRead);
        }
        stream.flush();
        stream.close();
        System.out.println( "You successfully uploaded " + upfile.getOriginalFilename() + "!" );

    } catch (Exception e) {
        System.out.println( "You failed to upload " + upfile.getOriginalFilename() + " => " + e.getMessage() ); ;
    }

}

Have you tried stream?

Jsp code:

<form method="POST" onsubmit="" ACTION="url?${_csrf.parameterName}=${_csrf.token}" ENCTYPE="multipart/form-data">

Controller:

 @RequestMapping(
        value = "url", method = RequestMethod.POST
)
public void uploadFile(
        @RequestParam("file") MultipartFile file
) throws IOException {

 InputStream input = upfile.getInputStream();
 Path path = Paths.get(path);//check path
 OutputStream output = Files.newOutputStream(path);
 IOUtils.copy(in, out); //org.apache.commons.io.IOUtils or you can create IOUtils.copy

}

All that worked for me with spring 4.0 and spring security.

Secondly, you should check if the http connection is timeout. Chrome does not support that configuration. So you can use firefox and follow here http://morgb.blogspot.com.es/2014/05/firefox-29-and-http-response-timeout.html.
