    }

    @Override
    public void start(Stage primaryStage) {
        ComboBox<String> comboBox = new ComboBox<>();

        // 建立数据库连接
        try (Connection conn = DriverManager.getConnection(DB_URL, DB_USER, DB_PASSWORD);
             Statement stmt = conn.createStatement();

            while (rs.next()) {
                String name = rs.getString("name");
                comboBox.getItems().add(name);
            }

        } catch (Exception e) {

        VBox root = new VBox(comboBox);
        primaryStage.setScene(new Scene(root, 200, 200));
        primaryStage.show();
    }
