Description: The reason to convert to BASE64 is because I am involved in the transfer of cross-system images. Transfer file to another system, and another system to upload files.

Between this, the process from A to B, the picture is present in one of the nodes in the XML. To the B system to do XML to map the process. So in this process, you cannot remove byte[] or file type files from the map. Because the value of the map after the conversion cannot be strongly converted to byte[] or file, it can only be converted to BASE64 string values. To the B end and then to byte[] for file upload operations
