Daha önce Jersey 1.x bilgisi olmadan sıfırdan başlayarak, Jersey 2.0 projemde bağımlılık enjeksiyonunu nasıl ayarlayacağımı anlamakta zorlanıyorum.
HK2'nin Jersey 2.0'da da mevcut olduğunu anlıyorum, ancak Jersey 2.0 entegrasyonuna yardımcı olacak dokümanları bulamıyorum.
@ManagedBean
@Path("myresource")
public class MyResource {
@Inject
MyService myService;
/**
* Method handling HTTP GET requests. The returned object will be sent
* to the client as "text/plain" media type.
*
* @return String that will be returned as a text/plain response.
*/
@GET
@Produces(MediaType.APPLICATION_JSON)
@Path("/getit")
public String getIt() {
return "Got it {" + myService + "}";
}
}
@Resource
@ManagedBean
public class MyService {
void serviceCall() {
System.out.print("Service calls");
}
}

Konteyneri kaynağımı başlatmak ve sunmak için alabilirim, ancak @Inject'i MyService'e ekler koymaz çerçeve bir istisna atıyor:
