Ich habe eine Spring Boot-Anwendung mit Jersey 2 REST-Diensten. Spring Boot scheint korrekt zu initialisieren und ich habe Jersey Spring bridge ('org.glassfish.jersey.ext: jersey-spring3: 2.22.2'). Trotzdem wird der folgende Fehler ausgelöst, dann wird der REST-Controller (JAX-RS 2.0) initialisiert und ein Spring Bean muss hineingejagt werden.HK2 sieht keine Frühlingsbohnen
org.glassfish.hk2.api.UnsatisfiedDependencyException: There was no object available for injection
Was kann einen solchen Fehler verursachen?
Die Bean ist vorhanden und mit @named annotiert, also ist es nicht das Problem. Spring Boot sucht standardmäßig auch nach JSR-330-Annotationen.
Edit: Initialisierung erfolgt mit:
@SpringBootApplication
public class Application extends SpringBootServletInitializer implements WebApplicationInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
}

Der Controller ist:

@Singleton
@Path("/RequestEndEvent")
public class RequestEndEventController {
private final Logger log = LoggerFactory.getLogger(getClass());
@Inject
private RequestEndEventLogger logger;
@POST

Wo ist Ihr 'RequestEventLogger'? Ich kann Ihnen sagen, dass Spring Service in Jersey/HK2-Ressourcen/Dienstleistungen kein Problem mit Spring Boot ist. Woher weißt du, dass der Logger tatsächlich im Spring-Kontext ist? Haben Sie versucht, 'ApplicationContext' zu injizieren und explizit' ctx.getBean (RELogger.class) 'zu versuchen, um zu sehen, ob es im Kontext ist? –
@peeskillet Sie haben Recht. Ich habe versucht, dass Sie vorgeschlagen und Spring ist nicht in der Lage, die Klasse zu finden. Es ist ein einfacher Klassengedanke mit \ @Named Annotation, also sollte es von Spring aufgenommen worden sein. – Sergey
In welchem Paket ist der Logger? Es sollte im gleichen Paket wie die Anwendungsklasse oder in einem Unterpaket sein, damit es im Scan abgeholt werden kann. –
