Hi, In my email about ideas what to do for Wicket 10 ( https://markmail.org/message/vpptsmt4ysxbktzc) I have suggested to drop @SpringBean and use jakarta.inject.Inject/Named instead. While working on it I've faced one issue - there is no support for non-required bean:
@SpringBean(required = false) private SomeBean someBean; If there is no matching bean in the Spring application context then nothing will be injected. Without 'required = false' the instantiation of the Component will fail with an Exception. With jakarta.inject APIs there is no way to say that something is optional. I've tried by using java.util.Optional: @Inject private Optional<SomeBean> someBean; but the problem here is that j.u.Optional is a final class and cannot be enhanced by CGLib to create a serializable proxy around it. Another option is to create a custom annotation, e.g. @Optional in wicket-ioc. Do you have other ideas ? Or should we stay with @SpringBean or even use Spring's @Autowired ?! Martin
