java生成图片并打印

最近做一个点菜宝项目,需要打印java后台嗲用打印机并且打印票据,思路是这样 先填充数据,然后生成图片,调用打印机直接打印图片!废话不多说直接上代码!

public class CreateImage{
 public static BufferedImage image;
 
 public static String createImage(String fileLocation) {
 try {
 FileOutputStream fos = new FileOutputStream(fileLocation);
 BufferedOutputStream bos = new BufferedOutputStream(fos);
 JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(bos);
 encoder.encode(image);
 bos.close();
 
 } catch (Exception e) {
 e.printStackTrace();
 }
 return fileLocation;
 }
 
 
 
 public static String  graphicsGeneration(List orderDishesList,OrderForm orderForm) {
 createDir("C://orderForm//image");
 int imageWidth = 400;//图片的宽度
 int imageHeight = 400+orderDishesList.size()*200;//图片的高度
 image = new BufferedImage(imageWidth, imageHeight, BufferedImage.TYPE_INT_RGB);
 Graphics graphics = image.getGraphics();
 graphics.setColor(Color.WHITE);
 graphics.fillRect(0, 0, imageWidth, imageHeight);
 graphics.setColor(Color.BLACK);
 Font fontTitle=new Font("楷体",Font.BOLD,35);
 graphics.setFont(fontTitle);
 graphics.drawString("点菜宝", 40, 25);
 Font font=new Font("宋体",Font.PLAIN,25);
 graphics.setFont(font);
 graphics.drawString("订单编号: " + orderForm.getFormCode(), 50, 75);
 graphics.drawString("对应楼层: " + orderForm.getDisk().getFloor().getFloorNum(), 50, 100);
 graphics.drawString("对应餐桌: " + orderForm.getDisk().getDiskCode(), 50, 125);
 graphics.drawString("订单时间: " + orderForm.getFormDate(), 50, 150);
 Integer  y=175;
 for(OrderDishes od:orderDishesList){
  y=y+25;
  graphics.drawString("菜名 : " +od.getDishes().getDishesName() , 50, y);
  y=y+25;
  graphics.drawString("价格 : " + od.getDishes().getPrice(), 50, y);
  y=y+25;
  graphics.drawString("份数: " + od.getNum(), 50, y);
  y=y+25;
  graphics.drawString("备注: " + od.getMemo(), 50, y);
  y=y+25;
 }
 //ImageIcon imageIcon = new ImageIcon(imgurl);
 //graphics.drawImage(imageIcon.getImage(), 230, 0, null);
 //改成这样:
 BufferedImage bimg = null;
 try {
    bimg = javax.imageio.ImageIO.read(new java.io.File("C://orderForm//image"+DateUtil.DateToStringHHSSMM(new Date())+orderForm.getFormCode()+".jpg"));
 } catch (Exception e) {
 }
 if(bimg!=null)
 graphics.drawImage(bimg, 230, 0, null);
 graphics.dispose();
 String  imageUrl=createImage("C://orderForm//image//"+DateUtil.DateToStringHHSSMM(new Date())+orderForm.getFormCode()+".jpg");
 return imageUrl;
 }

 
 public static boolean createDir(String destDirName) {
     File dir = new File(destDirName);
     if(dir.exists()) {
      System.out.println("创建目录" + destDirName + "失败,目标目录已存在!");
      return false;
     }
     if(!destDirName.endsWith(File.separator))
      destDirName = destDirName + File.separator;
     // 创建单个目录
     if(dir.mkdirs()) {
      System.out.println("创建目录" + destDirName + "成功!");
      return true;
     } else {
      System.out.println("创建目录" + destDirName + "成功!");
      return false;
     }
 }

}

生成图片 然后嗲用java自带的打印服务进行打印!
