android图片上传springMvc

android端：

String fileName = tvFilename.getText().toString();
        RequestBody description =
                RequestBody.create(
                        okhttp3.MultipartBody.FORM, fileName);

        File fileImage = new File(saveFileName);
        RequestBody requestBody1 =
                RequestBody.create(MediaType.parse("multipart/form-data"), fileImage);
        MultipartBody.Part body =
                MultipartBody.Part.createFormData("bannerImage", fileImage.getName(), requestBody1);


        RestClient.api().addLive(description, body)
        .enqueue(new retrofit2.Callback() {
            @Override
            public void onResponse(retrofit2.Call call, retrofit2.Response response) {
               "处理成功"
            }

            @Override
            public void onFailure(retrofit2.Call call, Throwable t) {
                "处理失败"
            }
        });

@Multipart
    @POST("add/live")
    Call<ResponseInfo> addLive(
            @Part("fileName")RequestBody fileName,//其他字段
            @Part MultipartBody.Part bannerImage);//图片

服务器端：

@RequestMapping(value = "/add/live", method = RequestMethod.POST)
    @ResponseBody
    public ResponseInfo addLive(
            @RequestParam(value = "fileName") String fileName,
            @RequestParam(value = "bannerImage") MultipartFile bannerImage
    )throws Exception {
        String logoPath = "/logo/score/";
        try {
                File file = new File(imagePath + logoPath);
                FileUtils.writeByteArrayToFile(file, bannerImage.getBytes());

        } catch (Exception e) {
            e.printStackTrace();
        }
        return new ResponseInfo(T1TConstants.SUCCESS, "成功");
    }
