java將圖片轉成base64編碼

InputStream in = null;  
byte[] data = null;  
//讀取圖片字節數組  
try   
   {  
      in = new FileInputStream(你的文件路徑);   //該路徑只能是本機路徑,不能是網絡地址       
      data = new byte[in.available()];  
      in.read(data);  
    }   
catch (IOException e)   
   {  
      e.printStackTrace();  
   } finally{
    try {
          if(in != null){
          in.close();	
        }
    } catch (IOException e) {
	    e.printStackTrace();
	}
 }
	BASE64Encoder encoder = new BASE64Encoder();  
	String code = "data:image/png;base64,"+encoder.encode(data).replaceAll("\n|\r","");
