Customizing entity validation
By default annotation validation is performed on all entities.
Customizing validation can be done by simply specifying a Validator bean that supports the specific entity type.
You can use the EntityValidatorSupport as a base class to extend the default annotation based entity validation.
Custom entity validator
@Component
public class SeatValidator extends EntityValidatorSupport<Seat> {
@Override
protected void preValidation(Seat entity, Errors errors, Object... validationHints) { (1)
}
@Override
protected void postValidation(Seat entity, Errors errors, Object... validationHints) { (2)
if (!errors.hasFieldErrors("seatNumber")) {
}
}
@Override
public boolean supports(Class<?> clazz) { (3)
return Seat.class.isAssignableFrom(clazz);
}
}| 1 | Do custom validation before the initial entity validation happens |
| 2 | Do custom validation after the initial entity validation happens |
| 3 | Return a boolean indicating if the validation needs to be triggered for that class |
If more than one Validator could be applied, you will manually have to set the Validator.class attribute on the EntityConfiguration to the correct one.
