java全屏截图代码实现

工作中,有时候会遇到需要截图的时候,如下示例两种为一个简单的实现java屏幕截图的方法,使用robot和ImgIO来实现,代码如下:

    private static String defaultImageFormat="png";
    public static Dimension d = Toolkit.getDefaultToolkit().getScreenSize();

    public static void snapShot(String filePath, String fileName) {        
        try {
            File file = new File(filePath);
            if(!file.exists()){

                boolean create = file.mkdirs();
            }
            //拷贝屏幕到一个BufferedImage对象screenshot
            BufferedImage screenshot = (new Robot()).createScreenCapture(new
                    Rectangle(0, 0, (int) d.getWidth(), (int) d.getHeight()));
            //根据文件前缀变量和文件格式变量,自动生成文件名
            String name=fileName+"_"+gethms()+"."+defaultImageFormat;
            String imagePath = filePath+File.separator+name;
            File f = new File(imagePath);
            log.info("Save File "+imagePath);
            //将screenshot对象写入图像文件
            boolean tof = ImageIO.write(screenshot, defaultImageFormat, f);
            if(tof){
                log.info("图片生成成功:"+name);
            }else{
                log.info("图片生成失败");
            }           
        }
        catch (Exception e) {
            log.error("截图失败", e);
        }
    }

    private static String gethms(){
        int hour=0;
        int minute=0;
        int second=0;
        Calendar c=Calendar.getInstance();//获系统前期
        hour=c.get(Calendar.HOUR);
        minute=c.get(Calendar.MINUTE);
        second=c.get(Calendar.SECOND);
        String time=String.valueOf(hour)+String.valueOf(minute)+String.valueOf(second);
        return time;
    }
