我试图使用'流'Apache Commons File Upload API上传大文件.

我使用Apache Commons File Uploader而不是默认的Spring Multipart上传器的原因是当我们上传非常大的文件大小(~2GB)时它失败了.我在一个GIS应用程序上工作,这种文件上传很常见.

我的文件上传控制器的完整代码如下:

@Controller
public class FileUploadController {

    @RequestMapping(value="/upload", method=RequestMethod.POST)
    public void upload(HttpServletRequest request) {
        boolean isMultipart = ServletFileUpload.isMultipartContent(request);
        if (!isMultipart) {
            // Inform user about invalid request
            return;
        }

        //String filename = request.getParameter("name");

        // Create a new file upload handler
        ServletFileUpload upload = new ServletFileUpload();

        // Parse the request
        try {
            FileItemIterator iter = upload.getItemIterator(request);
            while (iter.hasNext()) {
                FileItemStream item = iter.next();
                String name = item.getFieldName();
                InputStream stream = item.openStream();
                if …
