spring-poi-excle往單元格寫入圖片

 

HSSF是POI工程對Excel 97(-2007)文件操作的純Java實現 
XSSF是POI工程對Excel 2007 OOXML (.xlsx)文件操作的純Java實現 

在POI中有HSSFPatriarch對象，該對象為畫圖的頂級管理器，它的createPicture(anchor, pictureIndex)方法就能夠在Excel插入一張圖片。

步驟:

一、獲取HSSFPatriarch對象
二、new HSSFClientAnchor對象
三、調用createPicture方法

 

針對office2007以前的

public class ExcelImageTest {
    public static void main(String[] args) {
         FileOutputStream fileOut = null;   
         BufferedImage bufferImg = null;   
        //先把讀進來的圖片放到一個ByteArrayOutputStream中，以便產生ByteArray  
        try {
            ByteArrayOutputStream byteArrayOut = new ByteArrayOutputStream();   
            bufferImg = ImageIO.read(new File("F:/圖片/照片/無名氏/小昭11.jpg"));   
            ImageIO.write(bufferImg, "jpg", byteArrayOut);
            
            HSSFWorkbook wb = new HSSFWorkbook();   
            HSSFSheet sheet1 = wb.createSheet("test picture");  
            //畫圖的頂級管理器，一個sheet只能獲取一個（一定要注意這點）
            HSSFPatriarch patriarch = sheet1.createDrawingPatriarch();   
            //anchor主要用於設置圖片的屬性
            HSSFClientAnchor anchor = new HSSFClientAnchor(0, 0, 255, 255,(short) 1, 1, (short) 5, 8);   
            anchor.setAnchorType(3);   
            //插入圖片  
            patriarch.createPicture(anchor, wb.addPicture(byteArrayOut.toByteArray(), HSSFWorkbook.PICTURE_TYPE_JPEG)); 
            fileOut = new FileOutputStream("D:/測試Excel.xls");   
            // 寫入excel文件   
             wb.write(fileOut);   
             System.out.println("----Excle文件已生成------");
        } catch (Exception e) {
            e.printStackTrace();
        }finally{
            if(fileOut != null){
                 try {
                    fileOut.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}

HSSFClientAnchor(0, 0, 255, 255,(short) 1, 1, (short) 5, 8)這個構造函數造成的，下面我就來解釋這個構造函數：HSSFClientAnchor(int dx1,int dy1,int dx2,int dy2,short col1,int row1,short col2, int row2);各個參數的含義如下：

      dx1：the x coordinate within the first cell。

      dy1：the y coordinate within the first cell。

      dx2：the x coordinate within the second cell。

      dy2：the y coordinate within the second cell。

      col1：the column (0 based) of the first cell。

      row1：the row (0 based) of the first cell。

      col2：the column (0 based) of the second cell。

      row2：the row (0 based) of the second cell。

 

      這里dx1、dy1定義了該圖片在開始cell的起始位置，dx2、dy2定義了在終cell的結束位置。col1、row1定義了開始cell、col2、row2定義了結束cell。

實現插入多張圖片

HSSFClientAnchor anchor1 = new HSSFClientAnchor(0, 0, 1023,100,(short) 1, 1, (short)5, 8); 
HSSFClientAnchor anchor2 = new HSSFClientAnchor(0, 0, 1023,100,(short) 1, 9, (short)5, 16); 
            
            //插入圖片  
patriarch.createPicture(anchor1, wb.addPicture(byteArrayOut.toByteArray(), HSSFWorkbook.PICTURE_TYPE_JPEG)); 
patriarch.createPicture(anchor2, wb.addPicture(byteArrayOut.toByteArray(), HSSFWorkbook.PICTURE_TYPE_JPEG));
