In my Spring Data Neo4j 4 project - BeforeSaveEvent class is deprecated.
Also, previously I used a following code in order to setup created/updated date for my entities:
@EventListener
public void handleBeforeSaveEvent(BeforeSaveEvent event) {
Object entity = event.getEntity();
if (entity instanceof BaseEntity) {
BaseEntity baseEntity = (BaseEntity) entity;
if (baseEntity.getCreateDate() == null) {
baseEntity.setCreateDate(new Date());
} else {
baseEntity.setUpdateDate(new Date());
}
}
}
but right now this listener is not invoked.
Is there any replacement for this logic in Neo4j 4 ? I'll really appreciate an example. Thanks
UPDATED
The configuration described below is working but some of my tests are fail because of NULL dates on a previously saved entities.. something is still wrong..
After clarification found a reason of this issue and waiting for this bugfix Modifications during a onPreSave() event do not persist to the database
@Configuration
@EnableExperimentalNeo4jRepositories(basePackages = "com.example")
@EnableTransactionManagement
public class Neo4jTestConfig {
@Bean
public Neo4jTransactionManager transactionManager() throws Exception {
return new Neo4jTransactionManager(sessionFactory());
}
@Bean
public SessionFactory sessionFactory() {
return new SessionFactory("com.example") {
@Override
public Session openSession() {
Session session = super.openSession();
session.register(new EventListenerAdapter() {
@Override
public void onPreSave(Event event) {
Object eventObject = event.getObject();
if(eventObject instanceof BaseEntity) {
BaseEntity baseEntity = (BaseEntity) eventObject;
if (baseEntity.getCreateDate() == null) {
baseEntity.setCreateDate(new Date());
} else {
baseEntity.setUpdateDate(new Date());
}
}
}
});
return session;
}
};
}
}
