java - JTable 中的 java.net.malformedURLexception

Question

我有这段代码，当我单击 jtable 时，我的数据库中的图片将显示在我的界面中。但每次我点击 malformedUrlexception 时都会弹出。可以请人帮助我吗？

    private void recordTBLMouseClicked (java.awt.event.MouseEvent evt){
        String click = (recordTBL.getModel().getValueAt(row, 0).toString());
        try {
            clsConnect c = new clsConnect();
            Connection conn = c.makeConnection();
            String sql = "Select image from employeetbl where idnum = '" + click + "'";
            pst = conn.prepareStatement(sql);
            rs = pst.executeQuery();
            while (rs.next()) {

                URL imagedate = new URL("image");

                BufferedImage bufferedimage1 = ImageIO.read(imagedate);
                finalimage = new ImageIcon(resize(bufferedimage1, imageL.getWidth(), imageL.getHeight()));
                imageL.setIcon(finalimage);
            }
        } catch (Exception e) {
            JOptionPane.showMessageDialog(null, e);
        }
    }

这条线是你的问题：

URL imagedate = new URL("image");

“图像”不是 URL。您需要将有效的 URL 传递给 URL 构造函数。例如“ http://www.stackoverflow.com ”
