Guice module integration issue with REST - rest

Question

Guice module integration issue with REST
I have define one AOP guice based module, but when I tried to integrate with REST code, methodInvocation.proceed retun null.
What might be best way to solve this issue.
Define AOP Guice based module as below
#Retention(RetentionPolicy.RUNTIME)
#Target(ElementType.METHOD)
#interface NotOnWeekends {}
public class WeekendBlocker implements MethodInterceptor {
public Object invoke(MethodInvocation invocation) throws Throwable {
Calendar today = new GregorianCalendar();
if (today.getDisplayName(DAY_OF_WEEK, LONG, ENGLISH).startsWith("S")) {
throw new IllegalStateException(
invocation.getMethod().getName() + " not allowed on weekends!");
}
return invocation.proceed();
}
}
public class NotOnWeekendsModule extends AbstractModule {
protected void configure() {
bindInterceptor(Matchers.any(), Matchers.annotatedWith(NotOnWeekends.class),
new WeekendBlocker());
}
}
But I tried to Integrate this with my REST API
public class WorkerBean implements Worker {
#Autowired
private WorkerRepository workerRepository;
#Override
#NotOnWeekends
public Collection<Worker> findAll() {
Collection<Worker> workers = workerRepository.findAll();
return workers;
}
#RestController
public class WorkerController {
#RequestMapping(
value = "/api/workers",
method = RequestMethod.GET,
produces = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<Collection<Worker>> getWorkers() {
Worker worker = Guice.createInjector(new NotOnWeekendsModule()).getInstance(Worker.class);
Collection<Worker> worker = worker.findAll(); // return null
....
}
