java - HTML 页面在 JEditorPane 中未正确显示

问题描述

我有一个 Spring Boot 应用程序，它JFrame在触发事件时显示。框架显示 HTML 页面，但我在这里面临的问题是，当我手动打开 HTML 页面时，它在 chrome 浏览器中正确显示，如下所示：

但是当我试图通过我的应用程序在框架中打开同一页面时，它看起来像这样：

我已经尝试过，但无法弄清楚问题所在。下面是显示框架的代码：

public class BringUpFrame {

    static Logger logger = LoggerFactory.getLogger(BringUpFrame.class);
    private static final int SWP_NOSIZE = 0x0001;
    private static final int SWP_NOMOVE = 0x0002;
    private static final int TOPMOST_FLAGS = SWP_NOMOVE | SWP_NOSIZE;
    private static final HWND HWND_TOPMOST = new HWND(Pointer.createConstant(-1));
    private static JFrame frmOpt;
    static String Message;

    public static JFrame ShowBanner() throws IOException {

        int width = 0;
        int height = 0;
        String ScrnResol = getScreenResolution();
        String[] ScreenResolution = ScrnResol.split(",");

        try {
            width = Integer.parseInt(ScreenResolution[0]);
            height = Integer.parseInt(ScreenResolution[0]);

        } catch (NumberFormatException nfe) {
            logger.info("NumberFormatException: " + nfe.getMessage());
        }

        HWND windowHandle = User32Ext.INSTANCE.GetForegroundWindow();
        frmOpt = new JFrame("Banner");
        frmOpt.setExtendedState(JFrame.MAXIMIZED_BOTH);
        frmOpt.setPreferredSize(new Dimension(width, height));
        frmOpt.setUndecorated(true);
        frmOpt.setBackground(new Color(1.0f, 1.0f, 1.0f, 0.1f));
        frmOpt.setVisible(true);
        frmOpt.setAlwaysOnTop(false);
        frmOpt.setLocationRelativeTo(null);
        bringToForeground(getHWND(frmOpt), windowHandle);
        JPanel panel = new JPanel();

        panel.setLayout(new BorderLayout());

        JEditorPane jEditorPane = new JEditorPane();
        jEditorPane.setEditable(false);
        URL url = BringUpFrame.class.getClassLoader().getResource("test.htm");

        try {
            jEditorPane.setPage(url);
        } catch (IOException e) {
            jEditorPane.setContentType("text/html");
            jEditorPane.setText("<html>Page not found.</html>");
        }

        JScrollPane jScrollPane = new JScrollPane(jEditorPane);
        jScrollPane.setPreferredSize(new Dimension(width, height));
        panel.add(jScrollPane);

        frmOpt.add(panel);
        frmOpt.pack();
        frmOpt.setVisible(true);

        return frmOpt;

    }

    public static void disposeBanner() {
        frmOpt.dispose();
    }

    private static void bringToForeground(HWND clientWindow, HWND tillHandle) {
        User32Ext.INSTANCE.SetWindowPos(clientWindow, HWND_TOPMOST, 0, 0, 0, 0, TOPMOST_FLAGS);
    }

    private static HWND getHWND(Component comp) {
        return new HWND(Native.getComponentPointer(comp));
    }

    public static String getScreenResolution() {

        GraphicsDevice gd = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice();
        int width = gd.getDisplayMode().getWidth();
        int height = gd.getDisplayMode().getHeight();

        String resolution = width + "," + height;
        logger.info("Till Resolution is (width,height) : " + resolution);
        return resolution;

    }

}
