dear Jens,
thank you for this link. This was the code I was looking for!
If I my ask you to help me getting the final part of the puzzle (the group
validation) to work properly:
I have created my own Validation Group:
public interface *PrePersitValidationGroup* {}
In persistence.xml I have registered this group to be called only on
pre-persist:
<property name="javax.persistence.validation.group.pre-persist"
value="javax.validation.groups.Default,
com.emajstor.server.persistence.validator.*PrePersitValidationGroup*" />
<property name="javax.persistence.validation.group.pre-update"
value="javax.validation.groups.Default" />
<property name="javax.persistence.validation.group.pre-remove"
value="javax.validation.groups.Default" />
In my Entity I have assigned my custom validator to be a part of this group:
@UniqueUserName(groups=*PrePersitValidationGroup.class*, message="Username
is already in use! Please choose another user name.")
private String userName;
*How do I say in my CustomServiceLayerDecorator to validate
PrePersitValidationGroup on pre-persit only?*
Or let say: How do I take the settings from the persistence.xml into
account?
class CustomServiceLayerDecorator extends ServiceLayerDecorator {
@Override
public <T> Set<ConstraintViolation<T>> validate(T domainObject) {
return jsr303Validator.validate(domainObject,
PrePersitValidationGroup.class);
}
}
Thank you in advance for your help!
Best regards:
Nermin
