android实现图片上传功能（springMvc）

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<ResponseInfo>() {  @Override  public void onResponse(retrofit2.Call<ResponseInfo> call, retrofit2.Response<ResponseInfo> response) {  "处理成功"  }  @Override  public void onFailure(retrofit2.Call<ResponseInfo> 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

@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"); }
