Wrong profile is active - spring

Question

#SpringBootApplication
public class SfgDiApplication {
public static void main(String[] args) {
ApplicationContext ctx = SpringApplication.run(SfgDiApplication.class, args);
PetController petController = ctx.getBean("petController", PetController.class);
System.out.println("--- The Best Pet is ---");
System.out.println(petController.whichPetIsTheBest());
}
#Controller
#ResponseBody
public class PetController {
public PetController(PetService petService) {
this.petService = petService;
}
private final PetService petService;
#GetMapping("pet-type")
public String whichPetIsTheBest(){
return petService.getPetType();
}
}
public interface PetService {
String getPetType();
}
#Service("cat")
public class CatPetService implements PetService {
#Override
public String getPetType() {
return "Cats Are the Best!";
}
}
#Profile({"dog", "default"})
public class DogPetService implements PetService {
public String getPetType(){
return "Dogs are the best!";
}
}
application.properties
spring.profiles.active=dog
Result
--- The Best Pet is ---
Cats Are the Best!
I don't understand why cats are here. I can even comment the properties out, but cats are still here. I would like to see dogs.
What can I try next?

Answer 1

It looks like the DogService is not a bean. So in the end you only have a single bean (CatService) and this one will be picked all the time.

Answer 2

You should define a bean of DogPetService with #service.
You should add the cat profile to CatPetService.
Like this :
#Service("cat")
#Profile({"cat"})
public class CatPetService implements PetService {
#Override
public String getPetType() {
return "Cats Are the Best!";
}
}
#Profile({"dog", "default"})
#Service("dog")
public class DogPetService implements PetService {
public String getPetType(){
return "Dogs are the best!";
}
}

Answer 3

I think you can achieve what you want like this:
#Configuration("petConfig")
#RequiredArgsConstructor(onConstructor = #__(#Autowired))
public class PetConfig {
#Value("${spring.profiles.active}")
private String type;
#Bean(name = "petService")
#Primary
public PetService petService() {
PetService petService = null;
if ("cat".equals(type)) {
petService = new CatPetService();
}
if ("dog".equals(type)) {
petService = new DogPetService();
}
return petService;
}
}
Annotate both CatPetService and DogPetService with #Service. This way you can easily adapt the code without hardcodings and duplication.
