服务器端用于从android上传多个图像的java代码

Question

我从安卓代码中获取代码

下面是该代码的一部分。

protected String doInBackground(String... params) {
        try {
            String url = "http://192.168.1.21:8080/uploadimageserverside/upload.jsp";
            int i = Integer.parseInt(params[0]);
            Bitmap bitmap = decodeFile(map.get(i));
            HttpClient httpClient = new DefaultHttpClient();
            HttpContext localContext = new BasicHttpContext();
            HttpPost httpPost = new HttpPost(url);
            entity = new MultipartEntity();
            ByteArrayOutputStream bos = new ByteArrayOutputStream();
            bitmap.compress(CompressFormat.JPEG, 100, bos);
            byte[] data = bos.toByteArray();
            entity.addPart("user_id", new StringBody("199"));
            entity.addPart("club_id", new StringBody("10"));
            entity.addPart("club_image", new ByteArrayBody(data,"image/jpeg", params[1]));
            httpPost.setEntity(entity);
            HttpResponse response = httpClient.execute(httpPost,localContext);
            sResponse = EntityUtils.getContentCharSet(response.getEntity());
            System.out.println("sResponse : " + sResponse);
        } catch (Exception e) {
            if (dialog.isShowing())
                dialog.dismiss();
            Log.e(e.getClass().getName(), e.getMessage(), e);
        }
        return sResponse;
    }

但我不知道如何在服务器端为java编写代码来读取文件和写入。请提前帮我谢谢。

您可以使用Jersey Framework来构建您的所有者Restful，如果您不知道如何使用后端，则需要安装一些工具来配置Restful，请参阅以下内容：
