try {
// 先把读进来的图片放到一个ByteArrayOutputStream中,以便产生ByteArray
ByteArrayOutputStream byteArrayOut = new ByteArrayOutputStream();
//将图片读到BufferedImage
bufferImg = ImageIO.read(new File("C:/Users/uctimes/Desktop/1.jpg"));
// 将图片写入流中
ImageIO.write(bufferImg, "png", byteArrayOut);
// 创建一个工作薄
HSSFWorkbook wb = new HSSFWorkbook();
//创建一个sheet
HSSFSheet sheet = wb.createSheet("out put excel");
// 利用HSSFPatriarch将图片写入EXCEL
HSSFPatriarch patriarch = sheet.createDrawingPatriarch();
/**
* 该构造函数有8个参数
* 前四个参数是控制图片在单元格的位置,分别是图片距离单元格left,top,right,bottom的像素距离
* 后四个参数,前连个表示图片左上角所在的cellNum和 rowNum,后天个参数对应的表示图片右下角所在的cellNum和 rowNum,
* excel中的cellNum和rowNum的index都是从0开始的
*

//图片一导出到单元格B2中
HSSFClientAnchor anchor = new HSSFClientAnchor(0, 0, 0, 0,
(short) 10, 1, (short) 11, 2);
// 插入图片
patriarch.createPicture(anchor, wb.addPicture(byteArrayOut
.toByteArray(), HSSFWorkbook.PICTURE_TYPE_JPEG));
//生成的excel文件地址
fileOut = new FileOutputStream("C:/Users/uctimes/Downloads/123.xls");
// 写入excel文件
wb.write(fileOut);
} catch (IOException io) {
io.printStackTrace();
System.out.println("io erorr : " + io.getMessage());
} finally {
