java - 为什么相同的操作在 ActionListener 中有效，但在 @schedule 方法中无效？

Question

在以下代码片段中，actionPerformed() 方法和 aggiornaAutomaticamente() 方法执行相同的操作。为什么，在 GUI 中，我看到由 JButton 调用的 actionPerformed() 的更改，但使用 aggiornaAutomaticamente() @scheduled 方法，即使执行操作也不会出现更改？

由于操作是正确的，因此我没有粘贴所有代码，而只粘贴了其中的一部分。

@Configuration
@EnableScheduling
public class Appoggio {

    private JFrame frmClientPrestazioniChat;
    private DateTimePicker dateTimePickerDa;
    private DateTimePicker dateTimePickerA;
    private JCheckBox chckbxAggiornaAutomaticamente;
    private JPanel pnlFiltri;

    /**
     * Launch the application.
     */
    public static void main(String[] args) {

        // Comandi per usare spring
        AnnotationConfigApplicationContext ctx = new AnnotationConfigApplicationContext();
        ctx.register(Appoggio.class);
        ctx.refresh();

    }


    /**
     * Create the application.
     */
    public Appoggio() {
        initialize();
    }


    /**
