不知道是不是因为系统的原因

后台终端报错

......省略一大堆异常
Caused by: java.io.FileNotFoundException: /private/var/folders/fm/xd_7vyqx0cd6bmz9g2fsm4q80000gn/T/tomcat.4221560576543662726.9102/work/Tomcat/localhost/ROOT/Users/****/git/AndroidServer/SOBAndroidMiniWeb-master/sobUpload/biu.jpg (No such file or directory)

代码是按照大锯哥的教程走的

File file = new File("/storage/emulated/0/Pictures/biu.jpg");
RequestBody body = RequestBody.create(MediaType.parse("image/jpeg"),file);
MultipartBody.Part part = MultipartBody.Part.createFormData("file", file.getName(), body);
Call<PostFileResult> task = mApi.postWithFile(part);
task.enqueue(new Callback<PostFileResult>() {
    @Override
    public void onResponse(Call<PostFileResult> call, Response<PostFileResult> response)
    {
        Log.d(TAG, "onResponse: response.code() ====> "+response.code() );
        if (response.code() == HttpURLConnection.HTTP_OK) {
            Log.d(TAG, "onResponse: postWithFile ===>" +response.body());
        }
    }

    @Override
    public void onFailure(Call<PostFileResult> call, Throwable t)
    {
        Log.d(TAG, "onFailure: "+ t.toString());
    }
});

Log

response.code() ====> 200
postWithFile ===>PostFileResult{success=false, code=11111, message='上传失败.', data=null}

前面的请求都没有问题，到单文件上传这后台就报错了。
