I am calling a helper class inside a Service Impl. This class should use a bunch of Repositories, which are both Elasticsearch and JPA, and return an object back to the Service Impl. When I inject the repositories via the constructor in that class, I do not get a null for the repository objects.
However, I do not want to have all the repository objects in the constructor as then I would have to use them all as parameters in the Service Impl class using the @Autowired injections on the Service Impl.
For that reason, I tried injection through setters in the UserConverter class but still got nulls.
I configured all the SQL and Elasticsearch related repositories and already got results when injecting the repositories via the constructor.
I am missing something but could not figure out what it is. Hopefully, someone can answer that :) Thanks!
Controller
@Controller
public class MyController {
private final MyService myService;
@GetMapping("/getUser")
public ResponseEntity<GlobalSearch> doSearch(@RequestBody RequestData requestData) {
try {
User user = myService.getUser(requestData);
return new ResponseEntity<>(globalSearch, HttpStatus.OK);
} catch (NoSuchElementException | JsonProcessingException e) {
return new ResponseEntity<>(HttpStatus.NOT_FOUND);
}
}
}
Service
public interface MyService{
User getUser(RequestData requestData);
}
Service Impl
@Service
public class MyServiceImpl implements MyService {
@Override
public User getUser(RequestData requestData) {
User user = new UserConverter().convertUser(requestData);
}
}
Repository
@Repository
public interface UserRepository extends ElasticsearchRepository<User, String>, UserRepositoryCustom {
}
UserConverter
@Component
public class UserConverter{
private UserRepository userRepository;
//and at least 5 more JPA or Elasticsearch Repositories after..
//injection via constructor works tho.
@Autowired
public void setUserRepository(UserRepository userRepo) {
this.userRepository = userRepo;
}
public User convertUser(RequestData requestData(){
int age = userRepository.getAge("joe");
}
}
