HSSF是POI工程对Excel 97(-2007)文件操作的纯Java实现 
XSSF是POI工程对Excel 2007 OOXML (.xlsx)文件操作的纯Java实现 

在POI中有HSSFPatriarch对象,该对象为画图的顶级管理器,它的createPicture(anchor, pictureIndex)方法就能够在Excel插入一张图片。

步骤:

一、获取HSSFPatriarch对象
二、new HSSFClientAnchor对象
三、调用createPicture方法

 

针对office2007以前的

public class ExcelImageTest {
    public static void main(String[] args) {
         FileOutputStream fileOut = null;   
         BufferedImage bufferImg = null;   
        //先把读进来的图片放到一个ByteArrayOutputStream中,以便产生ByteArray  
        try {
            ByteArrayOutputStream byteArrayOut = new ByteArrayOutputStream();   
            bufferImg = ImageIO.read(new File("F:/图片/照片/无名氏/小昭11.jpg"));   
            ImageIO.write(bufferImg, "jpg", byteArrayOut);
            
            HSSFWorkbook wb = new HSSFWorkbook();   
            HSSFSheet sheet1 = wb.createSheet("test picture");  
            //画图的顶级管理器,一个sheet只能获取一个(一定要注意这点)
            HSSFPatriarch patriarch = sheet1.createDrawingPatriarch();   
            //anchor主要用于设置图片的属性
            HSSFClientAnchor anchor = new HSSFClientAnchor(0, 0, 255, 255,(short) 1, 1, (short) 5, 8);   
            anchor.setAnchorType(3);   
            //插入图片  
            patriarch.createPicture(anchor, wb.addPicture(byteArrayOut.toByteArray(), HSSFWorkbook.PICTURE_TYPE_JPEG)); 
            fileOut = new FileOutputStream("D:/测试Excel.xls");   
            // 写入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)这个构造函数造成的,下面我就来解释这个构造函数:HSSFClientAnchor(int dx1,int dy1,int dx2,int dy2,short col1,int row1,short col2, int row2);各个参数的含义如下:

      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。

 

      这里dx1、dy1定义了该图片在开始cell的起始位置,dx2、dy2定义了在终cell的结束位置。col1、row1定义了开始cell、col2、row2定义了结束cell。

实现插入多张图片

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); 
            
            //插入图片  
patriarch.createPicture(anchor1, wb.addPicture(byteArrayOut.toByteArray(), HSSFWorkbook.PICTURE_TYPE_JPEG)); 
patriarch.createPicture(anchor2, wb.addPicture(byteArrayOut.toByteArray(), HSSFWorkbook.PICTURE_TYPE_JPEG));

 

 

 

office2007(xml)以后

public class StartPoiExcelWriterImg {
    public static void main(String[] args) {  
        FileOutputStream fileOut = null;     
        BufferedImage bufferImg = null;     
       //先把读进来的图片放到一个ByteArrayOutputStream中,以便产生ByteArray    
       try {  
           ByteArrayOutputStream byteArrayOut = new ByteArrayOutputStream();     
           bufferImg = ImageIO.read(new File("C:\\Users\\huage\\Desktop\\121231\\1466685286772.jpg"));     
           ImageIO.write(bufferImg, "jpg", byteArrayOut);  
             
           XSSFWorkbook wb = new XSSFWorkbook();     
           XSSFSheet sheet1 = wb.createSheet("Sheet1");    
           //XSSFSheet sheet1 = wb.getSheet("Sheet1");
           //画图的顶级管理器,一个sheet只能获取一个(一定要注意这点)  
           XSSFDrawing patriarch = sheet1.createDrawingPatriarch();     
           //anchor主要用于设置图片的属性  
           XSSFClientAnchor anchor = new XSSFClientAnchor(0, 0, 255, 255,(short) 1, 1, (short) 5, 8);     
           anchor.setAnchorType(3);     
           //插入图片    
           patriarch.createPicture(anchor, wb.addPicture(byteArrayOut.toByteArray(), XSSFWorkbook.PICTURE_TYPE_JPEG));   
           fileOut = new FileOutputStream("C:\\Users\\huage\\Desktop\\121231\\11111.xlsx");     
           // 写入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();  
               }  
           }  
       }  
   }  
}
