在新版本的Apache POI中，HSSFDrawing类已经被废弃。您可以使用XSSFDrawing类来替代。

请将以下代码行： import org.apache.poi.hssf.usermodel.HSSFDrawing;

替换为： import org.apache.poi.xssf.usermodel.XSSFDrawing;

并将以下代码行： Drawing drawing = sheet.createDrawingPatriarch();

替换为： XSSFDrawing drawing = (XSSFDrawing) sheet.createDrawingPatriarch();
