Hi Paul,
I have put the Rest service in a separate bundle but that does not help.
I created a simplified case:
Component(service = RestImpl.class)
@JaxrsResource
@JaxrsApplicationSelect("(" + JaxrsWhiteboardConstants.JAX_RS_NAME +
"=MyApplication)")
@JSONRequired
@Produces(MediaType.APPLICATION_JSON)
public class RestImpl {
@Reference
private PersonService personService;
@GET
@Path("/test")
public String test() {
System.out.println("personService == null " + (personService ==
null));
return "test";
}
}
@Component(service = Application.class, property =
{"servlet.init.hide-service-list-page=false"} )
@JaxrsApplicationBase("example")
@JaxrsName("MyApplication")
public class MyApplicationImpl extends Application {
@Override
public Set<Class<?>> getClasses() {
HashSet<Class<?>> set = new HashSet<Class<?>>();
set.add(JacksonJsonProvider.class);
set.add(RestImpl.class);
return set;
}
public Set<Object> getSingletons() {
return Collections.<Object>singleton(RestImpl.class);
}
}
- Execution of endpoint /example/test results in personService == null, so no DI
- Disabling @JSONRequired results in personService != null, so DI work here
- Disabling @JaxrsApplicationSelect results in personService != null, so DI
work here
This drives me into the direction that there is no problem with dependencies.
It seems that if @JaxrsApplicationSelect and @JSONRequired are used at the same
time, no DI happens.
Best,
