Help !!! How to save entity log in entity in Hibernate/JPA call back events like @PostPersist @PostRemove @PostUpdate

[Gp P]

Hi Players ,

I have create and save and new entities when I am saving entity for purpose of aggregation , audit , and refreshing cache . I want to use JPA callback events because I am using curd module for admin part also for cleaner implementation rather than doing manually

1. Hibernate : I tried but I get all kinds of hibernate exception ,as 
2. Overriding entity _save method : If dont call save in overridden method entity doesn't , if call it goes into infinite loop
3. Hibernate  temprory session : Tring to figure out
4. Override Crud controller : Thinking of doing it .. which function to override ...perhaps save ? any examples

Guys , any help would be much appreciated!! , been up all night :-( , I hope I was able explain my problem 

Thanks

Hi List,

n way I save entity @PostPersist (all these hibernate callback event are pretty useless )

or by overriding _save()  method  , how to correctly overide _save() without it being recursive 

Please provide me a working solution ...on deadline :-(

Hi ,

I am trying to save entity in @PostPersist and update cache when I am saving Entity

But its not working , as per hibernate "A callback method must not invoke EntityManager or Query methods!" "

I tried overiding the _save meathod but without calling this.save it doent work , if call it it goes into recurrive loop :-(

any better solution which works ?

@Entity

public class SiteMeta extends Model {

public String name, tagline , twitterId, facebookId , contactEmail, contactAddress ;

@OneToOne

public Company company;

public String toString() {

   return name  ;

}

@PostPersist

@PostRemove

@PostUpdate

public void refreshCache(){

Logger.info("Repoulating siteMeta  ,something changed"+company.name);

new CacheAccess().repoulateSiteMetaCache(company.name);

}

public void _sav(){ 

 Logger.info(" Repoulating the site navigation , Category changed ->> " + name); save();

 new CacheAccess().repoulateSiteMetaCache(company.name);

 }

}
