Qualifier class

Qualifier annotation for specific bean selection

When multiple beans of the same type are available, use @Qualifier to specify which specific bean should be injected.

Example:

@Service()
@Qualifier('primary')
class PrimaryUserService implements UserService { }

@Service()
@Qualifier('secondary')
class SecondaryUserService implements UserService { }

@Component()
class UserController {
  @Autowired()
  @Qualifier('primary')
  late UserService userService;
}
