JAVA读取word内表格的图片，将几行几列写入图片名（非POI）

		ITable table = section.getTables().get(0);

		String output = "ReadTextFromTable.txt";

		if (textfile.exists())
		{
			textfile.delete();
		}
		textfile.createNewFile();
		FileWriter fw = new FileWriter(textfile, true);
		BufferedWriter bw = new BufferedWriter(fw);

		//创建List
		List images = new ArrayList();
		HashMap<String, Object> photoMap = new HashMap<>();

		//遍历表格中的行
		for (int i = 0; i < table.getRows().getCount(); i++)
		{
			TableRow row = table.getRows().get(i);
			//遍历每行中的单元格
			for (int j = 0; j < row.getCells().getCount(); j++)

				//遍历单元格中的段落
				for (int k = 0; k < cell.getParagraphs().getCount(); k++)
				{

					bw.write(paragraph.getText() + "\t");//获取文本内容

					//遍历段落中的所有子对象
					for (int x = 0; x < paragraph.getChildObjects().getCount(); x++)
					{
						Object object = paragraph.getChildObjects().get(x);
						//判定对象是否为图片
						if (object instanceof DocPicture)
						{
							//获取图片
							DocPicture picture = (DocPicture) object;
							images.add(picture.getImage());
							//得到当前表格的行和列
							String photoName = String.format("第%s行第%s列的图片.png", i + 1, j);
							photoMap.put(photoName,picture.getImage());

						}
					}
				}
			}
			bw.write("\r\n");//写入内容到txt文件
		}
		bw.flush();
		bw.close();
		fw.close();

		//将图片以PNG文件格式保存
//		for (int z = 0; z < images.size(); z++)
//		{
//			File imagefile = new File(String.format("提取的表格图片-%d.png", z));
//			ImageIO.write((RenderedImage) images.get(z), "PNG", imagefile);
//		}

		for (String s : photoMap.keySet()) {
			File imageFile = new File(s);
			ImageIO.write((RenderedImage) photoMap.get(s), "PNG", imageFile);

		}

	}
}

在此之前必须引入maven
