使用java從e​​xcel中獲取圖像

Question

我正在與Apache POI一起工作。我能夠從Excel中讀取數據，但無法從Excel中讀取圖像。如何從excel中讀取圖像。

Answer 1

而不是迷惑周圍讓我們有一個完整的例子。

import org.apache.poi.ss.usermodel.WorkbookFactory; 
import org.apache.poi.ss.usermodel.Workbook; 
import org.apache.poi.ss.usermodel.PictureData; 

import java.io.InputStream; 
import java.io.FileInputStream; 
import java.io.FileOutputStream; 

import java.util.List; 
import java.util.Iterator; 

class ReadExcelImages { 

public static void main(String[] args) throws Exception{ 

    InputStream inp = new FileInputStream("test.xls"); 
    //InputStream inp = new FileInputStream("test.xlsx"); 

    Workbook workbook = WorkbookFactory.create(inp); 

    List lst = workbook.getAllPictures(); 
    int i = 1; 
    for (Iterator it = lst.iterator(); it.hasNext();) { 
    PictureData pict = (PictureData)it.next(); 
    String ext = pict.suggestFileExtension(); 
    byte[] data = pict.getData(); 
    if (ext.equals("png")){ 
    FileOutputStream out = new FileOutputStream("pict" + i++ + ".png"); 
    out.write(data); 
    out.close(); 
    } else if (ext.equals("jpeg")) { 
    FileOutputStream out = new FileOutputStream("pict" + i++ + ".jpeg"); 
    out.write(data); 
    out.close(); 
    } 
    } 
} 
} 

對我的作品與HSSF（*.xls）以及與XSSF（*.xlsx）。
