Adnroid Retrifit2.0 多图片上传 服务端Java

Android端关于retrifit 2.0 多图片上传资料很多，但是相对应的webservice只找到几篇php的文章。初始，服务端接收了各种形式的参数都是null，通过抓接口才明白原来android和javaWeb传数据都是按web规范进行处理，android传递的是map，name全部相同，filename做区别，服务端根据name以数组形式接收参数。

Android核心代码:

/**多图片上传 */public void uploadImgList(Callback callback, Map<String, RequestBody> imgs){    ApiStore.uploadImgList con = retrofit.create(ApiStore.uploadImgList.class);Call<ImgBean> call = con.getInfo(imgs);call.enqueue(callback);

 File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/Download/", "icon.png");                File file1 = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/Download/", "icon1.png");                File file2 = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/Download/", "icon2.png");                                Map<String,RequestBody> imgs = new HashMap<>();                RequestBody requestImg = RequestBody.create(MediaType.parse("image/png"),file);                RequestBody requestImg1= RequestBody.create(MediaType.parse("image/png"),file1);                RequestBody requestImg2= RequestBody.create(MediaType.parse("image/png"),file2);                imgs.put("imgs\"; filename=\"icon.png",requestImg);                imgs.put("imgs\"; filename=\"icon1.png",requestImg1);                imgs.put("imgs\"; filename=\"icon2.png",requestImg2);

HttpClient.getInstance().uploadImgList(new Callback() {                    @Override                    public void onResponse(Call call, Response response) {                        ImgBean data = (ImgBean) response.body();                        if (data != null) {                            Snackbar.make(mButton2, "" + data.toString(), Snackbar.LENGTH_SHORT).show();                            Log.d("成功", data.toString());                        }                    }                    @Override                    public void onFailure(Call call, Throwable t) {                        Snackbar.make(mButton2, "" + t, Snackbar.LENGTH_SHORT).show();                        Log.d("失败", "");                    }                },imgs);               

Web核心代码:
