我正在研究我的截图方法。我现在添加了命名屏幕截图，我弹出了这个框，你可以在其中输入名称，但是一旦我输入名称并按确定，我就没有错误。但它不保存这是我的新代码

public void takeScreenshot() {
    try {

        Window window = KeyboardFocusManager.getCurrentKeyboardFocusManager().getFocusedWindow();
        Point point = window.getLocationOnScreen();
        int x = (int)point.getX();
        int y = (int)point.getY();
        int w = window.getWidth();
        int h = window.getHeight();
        Robot robot = new Robot(window.getGraphicsConfiguration().getDevice());
        Rectangle captureSize = new Rectangle(x, y, w, h);
        java.awt.image.BufferedImage bufferedimage = robot.createScreenCapture(captureSize);
                    String sn;
                    sn = JOptionPane.showInputDialog("Name Yout Screenshot");
        File file = new File((new StringBuilder()).append(SignLink.getCacheDirectory() + "Screenshots/" + sn + " ").append(".png").toString());
    } catch(Exception e) {
        e.printStackTrace();
    }
}

这是我工作时的代码

public void takeScreenshot() {
    try {
        Window window = KeyboardFocusManager.getCurrentKeyboardFocusManager().getFocusedWindow();
        Point point = window.getLocationOnScreen();
        int x = (int)point.getX();
        int y = (int)point.getY();
        int w = window.getWidth();
        int h = window.getHeight();
        Robot robot = new Robot(window.getGraphicsConfiguration().getDevice());
        Rectangle captureSize = new Rectangle(x, y, w, h);
        java.awt.image.BufferedImage bufferedimage = robot.createScreenCapture(captureSize);
        int picNumber = random(100);
        String fileExtension = "The Iron Door";
        File file = new File((new StringBuilder()).append(SignLink.getCacheDirectory() + "Screenshots/" + fileExtension + " ").append(picNumber).append(".png").toString());
        ImageIO.write(bufferedimage, "png", file);
    } catch(Exception e) {
        e.printStackTrace();
    }
}

我唯一更改的代码行是这一行

File file = new File((new StringBuilder()).append(SignLink.getCacheDirectory() + "Screenshots/" + fileExtension + " ").append(picNumber).append(".png").toString());

你遗漏了ImageIO.write(bufferedimage, "png", file);
