java操作poi將圖片從一個sheet複製到另一個sheet(兼容03與07)

1.我的poi版本

<dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi</artifactId>
            <version>4.1.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi-ooxml</artifactId>
            <version>4.1.0</version>
        </dependency>

2.獲取sheet中圖片的信息

這兩個函數分別獲取03與07excel中的圖片的信息（Anchor，圖片流，圖片類型）存入map中，用於在sheet中插入圖片。

/**
	 * 獲取圖片和位置 (xls)
	 */
	public static Map<String, Object> getPicturesFromHSSFSheet (HSSFSheet sheet) throws IOException {
	    Map<String, Object> map = new HashMap<String, Object>();
	    List<HSSFShape> list = sheet.getDrawingPatriarch().getChildren();
	    for (HSSFShape shape : list) {
	        if (shape instanceof HSSFPicture) {
	            HSSFPicture picture = (HSSFPicture) shape;
	            HSSFClientAnchor cAnchor = picture.getClientAnchor();
	            HSSFPictureData pdata = picture.getPictureData();
	            map.put("pictureAnchor", cAnchor);
	            map.put("pictureByteArray", pdata.getData());
	            map.put("pictureType", pdata.getPictureType());
	        }
	    }
	    return map;
	}

/**
	 * 獲取圖片和位置 (xlsx)
	 */
	public static Map<String, Object> getPicturesFromXSSFSheet (XSSFSheet sheet) throws IOException {
	    Map<String, Object> map = new HashMap<String, Object>();
	    List<POIXMLDocumentPart> list = sheet.getRelations();
	    for (POIXMLDocumentPart part : list) {
	        if (part instanceof XSSFDrawing) {
	            XSSFDrawing drawing = (XSSFDrawing) part;
	            List<XSSFShape> shapes = drawing.getShapes();
	            for (XSSFShape shape : shapes) {
	                XSSFPicture picture = (XSSFPicture) shape;
	                XSSFClientAnchor anchor = picture.getPreferredSize();
	                map.put("pictureAnchor", anchor);
		            map.put("pictureByteArray", picture.getPictureData().getData());
		            map.put("pictureType", picture.getPictureData().getPictureType());
	            }
	        }
	    }
	    return map;
	}

3.在sheet中插入圖片

此部分參考我的另外一篇博客Java操作POI4.1.0向Excel添加圖片兼容03(.xls)及07後(xlsx)兩個版本

public static void copyPicture(HSSFWorkbook workbook,String sourceSheetName,String targetSheetName) throws IOException {
		HSSFSheet sourceSheet=workbook.getSheet(sourceSheetName);
		HSSFSheet targetSheet=workbook.getSheet(targetSheetName);
		Map<String, Object> sourceSheetPicture=getPicturesFromHSSFSheet(sourceSheet);
		HSSFPatriarch drawing=targetSheet.createDrawingPatriarch();
		drawing.createPicture((HSSFClientAnchor) sourceSheetPicture.get("pictureAnchor"), 
				workbook.addPicture((byte[])sourceSheetPicture.get("pictureByteArray"),
						Integer.parseInt(sourceSheetPicture.get("pictureType").toString())));
		
	}
	
	public static void copyPicture(XSSFWorkbook workbook,String sourceSheetName,String targetSheetName) throws IOException {
		XSSFSheet sourceSheet=workbook.getSheet(sourceSheetName);
		XSSFSheet targetSheet=workbook.getSheet(targetSheetName);
		XSSFDrawing drawing=targetSheet.createDrawingPatriarch();
		Map<String, Object> sourceSheetPicture=getPicturesFromXSSFSheet(sourceSheet);
		drawing.createPicture((XSSFClientAnchor) sourceSheetPicture.get("pictureAnchor"), 
				workbook.addPicture((byte[])sourceSheetPicture.get("pictureByteArray"),
						Integer.parseInt(sourceSheetPicture.get("pictureType").toString())));
	}

4.測試主程序

	public static void main(String[] args) {
		String filePath="D:\\test.xlsx";
		FileInputStream fileInputStream=null;
		FileOutputStream fileOut=null;
		try {
//			fileInputStream=new FileInputStream(filePath);
//			HSSFWorkbook workbook=new HSSFWorkbook(fileInputStream);
//			copyPicture(workbook,"Sheet1","Sheet2");
//			fileOut=new FileOutputStream(filePath);
//			workbook.write(fileOut);
			fileInputStream=new FileInputStream(filePath);
			XSSFWorkbook workbook=new XSSFWorkbook(fileInputStream);
			copyPicture(workbook,"Sheet1","Sheet2");
			fileOut=new FileOutputStream(filePath);
			workbook.write(fileOut);
			System.out.print(" Success!");
		}catch (Exception e) {
	        e.printStackTrace();
		}finally {
			try {
				fileInputStream.close();
			} catch (IOException e) {
				e.printStackTrace();
			}
		}	
	}

注意：此程序只支持sheet只有一個圖片的情況，如果有兩個以上的圖片可有參考進行相應的修改！
