问题
I would like to stop Hibernate Envers from creating a version if the audited entity is deleted. The issue is, that instead of an delete version (REVTYPE: 2) and updated version (REVTYPE: 1) is inserted without calling onPostUpdate Event of Envers.

public class AuditConfig {
private HibernateEntityManagerFactory hibernateEntityManagerFactory;
@PostConstruct
public void registerEnversListeners() {
EnversService enversService =
hibernateEntityManagerFactory
.getSessionFactory()
.getServiceRegistry()
.getService(EnversService.class);
EventListenerRegistry listenerRegistry = hibernateEntityManagerFactory.getSessionFactory().getServiceRegistry().getService(EventListenerRegistry.class);
listenerRegistry.setListeners(EventType.POST_INSERT, new CustomAuditEventListenerPostInsert(enversService));
listenerRegistry.setListeners(EventType.POST_DELETE, new CustomAuditEventListenerPostDelete(enversService));
}
}
customEventListenerPostDelete.java:
package com.example.stackoverflow1.audit;
import com.example.stackoverflow1.model.Soup;
import org.hibernate.envers.boot.internal.EnversService;
import org.hibernate.envers.event.spi.EnversPostDeleteEventListenerImpl;
import org.hibernate.event.spi.PostDeleteEvent;
public class CustomAuditEventListenerPostDelete extends EnversPostDeleteEventListenerImpl {
public CustomAuditEventListenerPostDelete(EnversService enversService) {
super(enversService);
}
@Override
public void onPostDelete(PostDeleteEvent event) {
if (event.getEntity() instanceof Soup){
Soup soup = ((Soup) event.getEntity());
System.out.println("DELETE: " + soup);
}
}
}
Controller.java:
import com.sun.tools.javac.util.List;
import lombok.AllArgsConstructor;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@AllArgsConstructor
public class SoupController {
private SoupRepository soupRepository;
@RequestMapping(value = "create")
public Soup create() {
Ingredient ingredient = Ingredient.builder().name("ingredient").build();
Soup soup = Soup.builder()
.name("Soup")
.ingredients(List.of(ingredient))
.build();
return soupRepository.save(soup);
}
@RequestMapping(value = "delete")
public void delete() {
soupRepository.deleteById(1L);
}
}
After /create followed by /delete I would like to have just one Entry in Soup_AUD.
ID REV REVTYPE NAME
1 1 0 Soup
But instead I've got:
ID REV REVTYPE NAME
1 1 0 Soup
1 2 1 Soup
How can I avoid this delete audit?
