Spring MVC - lookup validators automatically

Suppose I have a sample entity class like this:

public class Address {
    ...
}

and a corresponding validator:

@Component
public AddressValidator implements Validator {

    @Override
    public boolean supports(Class<?> entityClass) {
        return entityClass.equals(Address.class);
    }

    @Override
    public void validate(Object obj, Errors errors) {
        ...
    }
}

When I use a controller like the following, everything works:

@RestController
@RequestMapping("/addresses")
public class AddressController {

    @Autowired
    private AddressValidator validator;

    @InitBinder
    protected void initBinder(WebDataBinder binder) {
        binder.setValidator(validator);
    }

    @RequestMapping(method=POST)
    public Long addNewAddress(@Valid @RequestBody Address address) {
        ...
    }
}

However, if I omit the validator registering part (i.e. the following), validation is not performed.

@Autowired
private AddressValidator validator;

@InitBinder
protected void initBinder(WebDataBinder binder) {
    binder.setValidator(validator);
}

Having to register validators manually seems pointless. Can I instruct Spring to look up validators automatically (similar to how controllers are looked up)?

It's a Spring Boot based application.
