Using bean validation, particular hibernate validator implementation is it possible to define certain groups to automatically be used on certain crud operations like create or update?
or are there some build in hibernate groups that are internally checked for those operations?

Validating constraints In the setUp() method, a Validator instance is retrieved from the ValidatorFactory . Validator instances are thread-safe and may be reused multiple times. The validate() method returns a set of ConstraintViolation instances, which you can iterate in order to see which validation errors occurred.
Hibernate Validator allows to express and validate application constraints. The default metadata source are annotations, with the ability to override and extend through the use of XML. It is not tied to a specific application tier or programming model and is available for both server and client application programming.
In contrast to request body validation a failed validation will trigger a ConstraintViolationException instead of a MethodArgumentNotValidException . Spring does not register a default exception handler for this exception, so it will by default cause a response with HTTP status 500 (Internal Server Error).
The @Valid annotation ensures the validation of the whole object. Importantly, it performs the validation of the whole object graph. However, this creates issues for scenarios needing only partial validation. On the other hand, we can use @Validated for group validation, including the above partial validation.
You're probably looking for "Hibernate event-based validation" under "ORM Integration". You can set properties to specify which groups to validate at different times by setting properties on the SessionFactory like so:
<property name="javax.persistence.validation.group.pre-persist">javax.validation.Default</property>
<property name="javax.persistence.validation.group.pre-update">javax.validation.Default</property>
<property name="javax.persistence.validation.group.pre-remove"></property>
The above is the default configuration if you don't specify anything. Specifically, the javax.validation.Default group is validated on creates and updates. Nothing is validated on deletes.
