Я использую шов 2.2.0. Я хочу динамически генерировать Excel и загрузить этот файл Excel.
Может кто-нибудь получить код, пожалуйста? Это мой код
public void getWriteExcelFile() {

я звонюиз внешнего интерфейса, как это
, но не загружается, если загружается, показывает размер как 0 байтов
, пожалуйста, предоставьте любую помощь
