@Multipart
@POST("网址")
Call<ResponseBody> addGoods(@Part("uploadfile") RequestBody body);

File file=new File(pathImg);

RequestBody body = RequestBody.create(MediaType.parse("multipart/form-data"), file);
Call<ResponseBody> call = myInterface.addGoods(body);
call.enqueue(new Callback<ResponseBody>() {
    @Override
    public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
        if (response.isSuccess()) {
            try {
                String string = response.body().string();
                if (!TextUtils.isEmpty(string)) {
                    callback.onSuccess(string);
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

    @Override
    public void onFailure(Call<ResponseBody> call, Throwable t) {
        callback.onError(t.getMessage());

});

 

javaweb后端接收代码

记得在Servlet类名上添加注解

@MultipartConfig
 Part part = request.getPart("uploadfile");
        InputStream inputStream = part.getInputStream();



        FileOutputStream outputStream = new FileOutputStream(new File("保存图片的文件夹路径", System.currentTimeMillis() + ".jpg"));

        byte[] byt = new byte[1024];

        int len;
        while ((len = inputStream.read(byt)) != -1) {
            outputStream.write(byt, 0, len);

        }

        outputStream.close();
        inputStream.close();
