如何选择多个图像并在jLabel中显示它们

Question

我试图以Java应用程序形式选择多个图像并将其保存在我的SQL Server中，并在单击“搜索”按钮时在jLabel中显示它们。 这些是我在“浏览”按钮中的代码：

 JFileChooser chooser = new JFileChooser();
    chooser.showOpenDialog(null);
    File f = chooser.getSelectedFile();
    filename = f.getAbsolutePath();
    ImageIcon imageIcon = new ImageIcon(new ImageIcon(filename).getImage().getScaledInstance(jLabel1.getWidth(), jLabel1.getHeight(), Image.SCALE_SMOOTH));
    jLabel1.setIcon(imageIcon);
    File image = new File(filename);
    try {
        FileInputStream fis = new FileInputStream(image);
        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        byte[] buf = new byte[1024];
        try {
            for (int readNum; (readNum = fis.read(buf)) != -1;) {
                bos.write(buf, 0, readNum);
            }
        } catch (IOException ex) {
            Logger.getLogger(testJFrame.class.getName()).log(Level.SEVERE, null, ex);
        }

        personImage = bos.toByteArray();
    } catch (FileNotFoundException ex) {
        Logger.getLogger(testJFrame.class.getName()).log(Level.SEVERE, null, ex);
    }

保存按钮：

 String name = jTextField1.getText();
    try {
        Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
    } catch (ClassNotFoundException ex) {
        Logger.getLogger(testJFrame.class.getName()).log(Level.SEVERE, null, ex);
    }

    try {
        Connection conn = DriverManager.getConnection("jdbc:sqlserver://localhost:1433;databaseName=test", "sa", "oraclee");
        String url = "INSERT INTO imageTable (name,photo) VALUES (?,?)";
        PreparedStatement ps = conn.prepareStatement(url);
        ps.setString(1, name);
        ps.setBytes(2, personImage);
        ps.executeUpdate();
        JOptionPane.showMessageDialog(null, "saved");
    } catch (SQLException ex) {
        JOptionPane.showMessageDialog(null, "sorry,, not saved!");
    }
