Hibernate Envers：禁止onPostDelete上的版本

Question

如果删除了审核的实体，我想阻止Hibernate Envers创建版本。问题是，没有插入删除版本（REVTYPE：2）和更新版本（REVTYPE：1），而未调用Envers的onPostUpdate事件。

auditConfig.java：包com.example.stackoverflow1.audit;

import lombok.AllArgsConstructor;
import org.hibernate.envers.boot.internal.EnversService;
import org.hibernate.event.service.spi.EventListenerRegistry;
import org.hibernate.event.spi.EventType;
import org.hibernate.jpa.HibernateEntityManagerFactory;
import org.springframework.stereotype.Component;

import javax.annotation.PostConstruct;

@Component
@AllArgsConstructor
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);
    }

}

在/ create之后再加上/ delete之后，我想在Soup_AUD中具有仅一个条目。

ID REV REVTYPE NAME

1 1 0汤

但是我却得到了：

ID REV REVTYPE NAME

1 1 0汤

1 2 1汤

如何避免这种删除审核？

可以检出项目-> https://github.com/MoritzMeinhardt/hibernate-envers.git

我相信您正面临这个问题，因为Envers如何处理将更改应用于集合的拥有实体。

[您可以尝试将org.hibernate.envers.revision_on_collection_change设置为false，但是请注意，这是针对所有审计实体的，并且当前不能定位到特定的实体类型或关系。
