How to inject private field with annotation?

Answer 1

You have to use @Value annotation:

public class MainFrame extends JFrame {

  @Value("my title")
  private String title;

or if the value is some dynamic variable then you use:

@Value("#{beanA.title}")
  private String title;

Update

If you have to set to the parent then:

      @Value("my title")
      @Override
      public void setTitle(String title){
         super.setTitle(title);
      }
