AsyncHttpClient上传文件,服务器报异常 Stream ended unexpectedly

[xhf_3344]

使用 AsyncHttpClient做文件上传,服务器报 Processing of multipart/form-data request failed. Stream ended unexpectedly 这样的异常提示. 用浏览器在页面上表单提交是可以的,服务端代码应该没问题,在Android中就不行,服务器始终报

org.apache.commons.fileupload.FileUploadBase$IOFileUploadException: Processing of multipart/form-data request failed. Stream ended unexpectedly

该什么解决啊???中午到现在 快疯了都......

代码

    @Override
    public void onClick(View v) {
        String url_str = "http://192.168.1.102:8080/web/servlet/UploaderServlet";
        String filepath = et_filepath.getText().toString().trim();
        try {
            File file = new File(filepath);
            if (file.exists() && file.length() > 0) {
                AsyncHttpClient client = new AsyncHttpClient();

                RequestParams params = new RequestParams();
                params.put("profile_picture", file);

                client.post(url_str, params, new AsyncHttpResponseHandler() {
                    @Override
                    public void onSuccess(int i, Header[] headers, byte[] bytes) {
                        Toast.makeText(MainActivity.this, "文件上传成功", Toast.LENGTH_SHORT).show();
                    }

                    @Override
                    public void onFailure(int i, Header[] headers, byte[] bytes, Throwable throwable) {
                        Toast.makeText(MainActivity.this, "文件上传失败:" + i, Toast.LENGTH_SHORT).show();
                    }
                });
            } else {
                Toast.makeText(MainActivity.this, "文件不存在", Toast.LENGTH_SHORT).show();
            }

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

	public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		// 判断上传的数据是表单数据还是一个带文件的数据
		boolean isMultipart = ServletFileUpload.isMultipartContent(request);
		if (isMultipart) {
			// 拿到servlet的真实路径
			String realpath = request.getSession().getServletContext().getRealPath("/files");
			File dir = new File(realpath);
			if (!dir.exists())
				dir.mkdirs(); // 如果目录不存在 把这个目录给创建出来

			FileItemFactory factory = new DiskFileItemFactory();
			ServletFileUpload upload = new ServletFileUpload(factory); // 获取到上传文件的对象upload
			upload.setHeaderEncoding("UTF-8");
			try {
				List<FileItem> items = upload.parseRequest(request);
				for (FileItem item : items) {
					if (item.isFormField()) { // 上传的数据类型 是一个表单类型
						String name1 = item.getFieldName();// 得到请求参数的名称
						String value = item.getString("UTF-8");// 得到参数值
						System.out.println(name1 + "=" + value);
					} else {
						// 说明是一个文件类型 进行上传
						item.write(new File(dir, System.currentTimeMillis() + item.getName().substring(item.getName().lastIndexOf("."))));
					}
				}
			} catch (Exception e) {
				e.printStackTrace();
			} finally {
			}
		}

感觉如果不是上传的文件有问题就是服务器对上传的东西做了一些限制比如上传的大小等
