The DEXTUploadNJMultipartResolver object is responsible for separating the form data and generating temporary files in the tempRepository location. After that, it is necessary to describe the code to be processed with the method mapped to the controller, since the implementation method differs depending on the service, since it is necessary to move and copy the temporary file to the place where it is actually saved.
