excel文件如图

，获取张三的基本信息及图片信息。

代码如下：

需要导入poi相关的jar 版本3.9及以上

public class ReadExcel {

public static void main(String[] args) throws Exception {

InputStream inp = new FileInputStream("F:\\xxx.xls");

HSSFWorkbook workbook = (HSSFWorkbook) WorkbookFactory.create(inp);

List<HSSFPictureData> pictures = workbook.getAllPictures();

HSSFSheet sheet = (HSSFSheet) workbook.getSheetAt(0);

Map<String,Object> map = new HashMap<String,Object>();

for (HSSFShape shape : sheet.getDrawingPatriarch().getChildren()) {

HSSFClientAnchor anchor = (HSSFClientAnchor) shape.getAnchor();

if (shape instanceof HSSFPicture) {

HSSFPicture pic = (HSSFPicture) shape;

int row = anchor.getRow2();

int col = anchor.getCol2();

System.out.println("--->" + anchor.getRow2() + ":" + anchor.getCol2());

//map.put(row+":"+col, row+":"+col);

int pictureIndex = pic.getPictureIndex()-1;

HSSFPictureData picData = pictures.get(pictureIndex);

System.out.println("--->" + picData);

map.put(row+":"+col, picData);

savePic(UUID.randomUUID().toString(), picData);

}

}

System.out.println(map);

}

private static void savePic(String i, PictureData pic) throws Exception {

String ext = pic.suggestFileExtension();

byte[] data = pic.getData();

if (ext.equals("jpeg")) {

FileOutputStream out = new FileOutputStream("F:\\" + i + ".jpg");

out.write(data);

out.close();

File file = new File("F:\\" + i + ".jpg");

FileInputStream in = new FileInputStream(file);

System.out.println("in===>"+in);

if(file.isFile()){

file.delete();

System.out.println("=============delete");

}

}

/* if (ext.equals("png")) {

FileOutputStream out = new FileOutputStream("F:\\" + i + ".jpg");

out.write(data);

out.close();

} */

}

}
