Spring bean injection into a hibernate validator constraint

Question

I have a controller method like listed below whose argument is annotated with @Valid to validate PasswordChange object using a Hibernate validator @Constraint. Both PasswordChange and a sample constraint are listed below. As you can see, I am injecting up loginDao inside the constraint. Is this an anti-pattern ?

The other alternative I can think of is injecting the daos into the PasswordChange object so that the loginDao's are available inside the implementations of ConstraintValidator<A, V>. Somebody said that mixing data with business logic is an anti-pattern in spring.

Any suggestions are welcome.

Controller Method

---

@RequestMapping(value = "/passwordChange", method = RequestMethod.POST)
public @ResponseBody PasswordInfo passwordInfo(@RequestBody @Valid PasswordChange passwordChange)
 throws PasswordChangeException {
 return passwordService.changePassword(passwordChange.getLoginKey(), passwordChange.getOldPassword(), passwordChange.getNewPassword());
}

PasswordChange Bean

---

public class PasswordChange {
 @LoginAttemptsExceeded
 private String loginKey;
 private String oldPassword;
 private String newPassword;
 @Autowired
 private LoginDao loginDao;
 private LoginEntity login;
 private Person person;
 public PasswordChange() { 
 }
 public PasswordChange(String loginKey, String oldPassword, String newPassword) {
 this.loginKey = loginKey;
 this.oldPassword = oldPassword;
 this.newPassword = newPassword; 
 }
 @PostConstruct
 public void postInit() {
 login = loginDao.findByLogin(loginKey);
 person = login.getCorePerson();
 }
}

Sample Constraint

---

@Target({ FIELD, ANNOTATION_TYPE })
@Retention(RUNTIME)
@Constraint(validatedBy = LoginAttemptsExceededValidatorLoginId.class)
@Documented
public @interface LoginAttemptsExceeded {
 String message() default "{com.mrll.global.core.constraint.loginAttemptsExceeded}";
 Class<?>[] groups() default {};
 Class<? extends Payload>[] payload() default {};
}

Sample Constraint Validator

---

public final class LoginAttemptsExceededValidatorLoginId implements ConstraintValidator<LoginAttemptsExceeded, String> {
 @Resource
 private LoginDao loginDao;
 private LoginAttemptsExceeded loginAttemptsExceeded;
 @Override
 public void initialize(final LoginAttemptsExceeded loginAttemptsExceeded) {
 this.loginAttemptsExceeded = loginAttemptsExceeded;
 }
 /**
 * Validation fails if the login attempts have exceeded the preset number.
 * @param loginId
 * @param constraintValidatorContext
 * @return
 */
 @Override
 public boolean isValid(final String loginId, final ConstraintValidatorContext constraintValidatorContext) {
 if(StringUtility.IsEmpty(loginId)) return false;
 return !loginDao.findByLogin(loginId).isLoginAttemptsExceeded();
 }
}
