Java Jpa未刷新删除

java spring hibernate jpa

Java Jpa未刷新删除,java,spring,hibernate,jpa,spring-data-jpa,Java,Spring,Hibernate,Jpa,Spring Data Jpa,我有以下代码： @Transactional public class DbCrudServiceImpl implements DbCrudService { @Override public void cleanupDb() { ... serviceUserRepository.deleteAll(); //Spring data JPA repository for entity ServiceUser serviceUs

我有以下代码：

@Transactional
public class DbCrudServiceImpl implements DbCrudService {

    @Override
    public void cleanupDb() {
        ...
        serviceUserRepository.deleteAll(); //Spring data JPA repository for entity ServiceUser
        serviceUserRepository.flush();
        ...

    }

    ...
}

这是一种春豆

我在Jpa属性中将

org.hibernate.event.internal.AbstractFlushingEventListener的记录器设置为DEBUG
，以检查cleanupDb中发生的情况
显示了cleanupDb生成的日志行：
23:18:53.398 [main] DEBUG o.h.e.i.AbstractFlushingEventListener:149 - ## Processing flush-time cascades
23:18:53.401 [main] DEBUG o.h.e.i.AbstractFlushingEventListener:189 - ## Dirty checking collections

为什么没有delete语句？
为什么没有刷新它？
这可能是因为Hibernate遍历整个对象图，如果父对象没有被删除，它会取消子对象的删除
您可以通过将日志级别更改为跟踪并查找来自Hibernate的以下消息来检查这一点：
取消调度实体删除
