Spring Autowired NullPointerException

I am using spring for dependency injection, so I have a class which uses swing for user interface, however when I want to use @Autowired for any swing objects I get NullPointerException.

Here is the class:

@Component
public class PanelImpl implements Panel {

    @Autowired
    @Qualifier("getJPanel")
    private JPanel panel;

    //@Autowired
    private JButton getInfoBtn = new JButton();

    public PanelImpl() {
        init();
    }

    private void init() {
        setPanel();
    }

    private void setPanel() {
        getInfoBtn.setText("Get Info");
        panel.add(getInfoBtn);
    }

    @Override
    public JPanel getPanel() {
        return panel;
    }
}

And here is the Configuration class:

@Configuration
@ComponentScan("ooc")
@PropertySource("app.properties")
public class SpringConfiguration {

    @Bean
    public static PropertySourcesPlaceholderConfigurer getPropertySourcesPlaceholderConfigurer() {
        return new PropertySourcesPlaceholderConfigurer();
    }

    @Bean
    public Panel getPanel() {
        Panel PanelImpl = new PanelImpl();
        return PanelImpl;
    }


    @Bean
    public JPanel getJPanel(){
        return new JPanel();
    }

}

So any suggestions how I can use spring for injecting swing objects? Thanks in advance.
